Keeping Sensitive Client Data Safe
20 April 2020
With a strong focus on protecting client data, leading international legal business, DAC Beachcroft LLP has adopted Tessian’s machine intelligent email security platform to support the firm’s new cyber security strategy. Being deployed across its offices in Europe, Asia Pacific and Latin America, the platform will help prevent the firm’s 2,500 employees from sending misdirected emails that could potentially lead to loss of confidential client data. DAC Beachcroft LLP is leading the move towards legal firms becoming more digitally focused with security being at the forefront of that movement. It looked to Tessian to offer a platform that would not only give employees peace of mind when handling sensitive client data but allowed staff to be more flexible when using email on the move across any device or operating system (OS). The platform also delivered a solution that was quick to install with minimal disruption and was easy to use for busy lawyers and support teams alike. “Our staff deal with highly sensitive client data on a daily basis and we wanted to be able to support the teams to work with that personal information confidently without the fear of a data breach,” comments, Andrew Keith, COO, DAC Beachcroft LLP. “Just by having the Tessian platform in place has significantly reduced risks at DAC Beachcroft LLP within just four weeks. It captures what could potentially be a massive data breach, and the benefits have been almost immediately recognized by all at the firm.” David Aird, IT Director DAC Beachcroft LLP, continues; “Our lawyers are busy with client work, and the simplicity of the platform has meant they and their support staff don’t have to worry about simple human errors such as entering the wrong email address.  The Tessian platform stood out from other solutions on the market because its machine learning approach meant we could automatically protect the firm from misdirected emails, unauthorized emails and non-compliance on the network.” Tessian uses machine intelligence to understand normal email communication patterns in order to automatically identify email security threats, without the need for end user behavior change or pre-defined rules and policies. “DAC Beachcroft LLP is one of the leading legal firms to create a digital environment for its network. The firm has invested time and money in the best security solutions to protect client data and its staff from potential serious email breaches. We’re delighted to be part of that move to become a secure digital business and see a long partnership ahead,” comments Tim Sadler, CEO of Tessian.

Cybersecurity Awareness Should Be People-Centric, Too
13 March 2020
The first speaker at Tessian Human Layer Security Summit on March 5 was Mark Lodgson, Head of Cyber Assurance and Oversight at Prudential.  He started his presentation by citing three fundamental flaws in cybersecurity awareness training: It’s boring It’s often irrelevant  It’s expensive 
So, should we do away with it entirely? Not quite. Cybersecurity training is a necessary evil Cybersecurity professionals who implement training programs and employees who take part in these training programs can no doubt attest that the three flaws Mark mentioned are an unfortunate reality.  But, what’s the solution? Training is, after all, a necessity. Without it, employees would rely entirely on often small and overworked IT and cybersecurity teams to prevent incidents and mitigate the consequences afterward.  That’s not just a tall order; it’s completely unfeasible, especially when human error is the most prevalent cause of data breaches. That means every individual must be held accountable.  By educating employees about data privacy laws, password best practices, and how to spot phishing scams, cybersecurity becomes the collective responsibility of the organization, not just those who have a relevant title. With that said, Mark isn’t suggesting that organizations do away with cybersecurity awareness training. Instead, he’s saying that in order for it to be effective, it needs to be aligned to the individual business.  To do that, you have to get to know the business, the people in it, and their attitudes towards security. And, according to Mark, the best indicator of future behavior is confidence. The cybersecurity culture survey
Influenced by the work of Phillip Tetlock, Mark created a survey with predictive power. But, unlike your average survey that simply gauges knowledge, this survey gauges confidence.  Importantly, the survey focused on five key competencies: Business focus Cyber risk assessment Policy and best practice Cybersecurity advocacy Personal practice The thought process is simple: a survey respondent who answers a question incorrectly with 100% confidence is just as likely to make a mistake as a survey respondent who answers a question correctly with less than 100% confidence. Both responses signal the potential for equally risky behaviors. Beyond that, though, the responses – either correct or incorrect – represent an area that requires targeted training and intervention. How can you apply this to your cybersecurity strategy? While Mark shared the results of the survey he conducted (which you can see by watching the full presentation on our YouTube channel) his findings won’t help cybersecurity professionals fine-tune their own training. The key here is that awareness training needs to be customized.  Without gauging not just the knowledge but the confidence of your employees, you’re essentially blind to the cybersecurity risks within your organization. And, of course, your efforts run the risk of being deemed “boring”, “irrelevant”, and “expensive” with no tangible upside.

Mitigating the Risk of Data Exfiltration in a Regulated Industry
19 February 2020
McMillan Williams Solicitors (MW) is a British consumer high street law firm. It is a top 10 conveyancing law firm, operating across the south of England with a mission to provide accessible, affordable, inclusive, innovative and personal legal services. MW Solicitors is protecting 450 employees with Tessian Guardian, Tessian Enforcer and Tessian Constructor.
Making security a priority MW Solicitors provides legal advice to clients across the UK. Chief Information Officer David Fazakerley is responsible for ensuring that the firm’s IT infrastructure is efficient and fit for purpose. With over 1,000 new clients every month, protecting client data is a top priority.  Due to the high volume of clients, MW Solicitors’ attorneys must be efficient when tending to client needs. David notes that because of the pace of work, “mistakes can easily happen on email, especially due to features like autocomplete, which can lead to an email being accidentally sent to the wrong person.” David identified misdirected and unauthorized emails as two key problems that could compromise the firm’s data security.  What’s more, from a compliance point of view, data loss and exfiltration can cause significant issues for law firms, resulting in many hours spent on incident management and potentially having to file a report to the ICO. Seeking a solution that would ensure that their sensitive data remains secured, MW Solicitors turned to Tessian.
Efficiently mitigating the risk of data loss Tessian’s ability to easily integrate into MW Solicitors’ layered security system without having an impact on the infrastructure was a key benefit for the firm’s Risk and Compliance team. Tessian produced positive results shortly after deployment.  MW Solicitors deployed Tessian Guardian to prevent accidental data loss due to misdirected emails. One of the most common mistakes that can lead to a misdirected email is an employee inputting the wrong client email into a case management system. “This can be as simple as putting in hotmail.com instead of hotmail.co.uk,” notes Charlotte Mays, Compliance and Data Protection Manager. This is a problem because case management systems are unable to recognize such mistakes. Tessian Guardian can prevent emails from being sent to an incorrect address saved in the case management system. It does this by analyzing the firm’s historical email data in order to understand sending patterns and relationships between contacts. By learning what the “normal” or correct email address is from previous communications, Tessian Guardian can automatically identify the abnormal email address and notify the user that the incorrect recipient has been included in the email.  MW Solicitors also deployed Tessian Enforcer to prevent data exfiltration by email to personal or non-business domains. Tessian Enforcer understands the difference between authorized and unauthorized accounts by looking at emails that each employee has sent and received in the past in order to identify non-business contacts. If an employee sends an email to an unauthorized account, Charlotte and her team are now able to easily detect this. This has been “a huge improvement, as before it might have been difficult to even identify the employee in the first place,” notes Charlotte. MW Solicitors’ Risk and Compliance team are now able to review the Tessian dashboard to see in real time if data has been sent to unsafe destinations. 
Building a culture of transparency David aims to build a culture of transparency when it comes to data security. If all employees have an understanding of the security solutions in place, David believes that this will improve employee awareness and accountability. As MW Solicitors continues to grow, highlighting the importance of data security will be vital.  Human error is a constant, but if employees are armed with the right tools to prevent mistakes from occurring in the first place, then damage can be minimized or avoided altogether.  Learn more about how Tessian prevents human error on email Tessian is building the world’s first Human Layer Security platform to automatically secure all human-digital interactions within the enterprise.

Strengthening Security in Biotechnology
11 February 2020
Gubra is a Danish biotechnology company that was founded in 2008. Gubra focuses on preclinical contract research services and drug discovery programs within the metabolic space. The organization has established itself across the globe as a highly professional and competent partner within academia, biotechnology and the pharmaceutical industry. Gubra is protecting 160 employees with Tessian Defender and Tessian Guardian.
Taking security seriously Gubra is a Danish preclinical contract research organization that specializes in model building and drug testing for a variety of metabolic diseases. Chief Technology Officer Morten Høgholm Pedersen oversees IT development, implementation and operations. With many of the globe’s largest pharmaceutical companies as customers, ensuring that Gubra’s IT systems remain secure is a top priority. Many of Gubra’s clients are very sensitive to data security due to the nature of the biotechnology industry. Therefore, it is imperative that their information remains safeguarded within the organization. “We share data via password protected fileshare solutions. So even though sensitive data would not be compromised, misdirected emails that employees could accidentally send would still seem unprofessional and undermine our reputation,” says Morten. Additionally, with the rise in spear phishing attacks, Gubra also needed a solution that would better protect the organization from inbound threats on email. Gubra turned to Tessian.
Upholding credibility through secured systems Tessian was successfully implemented into Gubra’s security stack. Administered by Gubra’s IT team and overseen by Morten, Tessian gives Gubra transparency into their email security. Gubra is now protected from accidental data loss due to misdirected emails with the implementation of Tessian Guardian. For Gubra, the most powerful feature is Tessian Guardian’s ability to automatically identify an abnormal email address and notify users in real time that the potentially wrong recipient has been included. “The pop-up warning that tells people they could be sending an email to the wrong person has had a learning effect on the organization,” notes Morten. For Gubra, Tessian Guardian has led employees to become even more cautious. Many spear phishing attempts try to lure employees into paying fake invoices; and attackers are convincingly impersonating familiar parties. For Morten, the biggest concern for the organization is maintaining data security and credibility. Tessian Defender automatically prevents advanced impersonation-based spear phishing attacks by using stateful machine learning models to analyze historical email data and understand relationship context. Tessian Defender can detect impersonation from both internal and external parties and is helping Gubra defend itself from inbound threats.
Staying vigilant in a changing environment Human error is inevitable, and people will make mistakes on email, but they can be mitigated if the right tools are in place. For Morten, “it should be a standard for all companies to have a high degree of protection using the most advanced tools available against phishing attempts and misdirected emails.” With attackers getting more sophisticated with their tactics, it will be important for organizations to stay proactive with their security strategy. Gubra can now ensure that their clients’ sensitive data remains secured.

Insights on Human Layer Security from Tim Fitzgerald, CISO of Arm
23 January 2020
In case you missed it, on January 22 Tim Sadler, Tessian’s CEO and co-founder, hosted our first webinar of the year which explored the biggest threat to an organization’s security: its employees. To understand the risk of human error in the workplace and how Tessian’s Human Layer Security platform is able to mitigate that risk, Tim S. was joined by Tim Fitzgerald, the CISO of Arm for a live Q&A. Before joining Arm over two years ago, Tim F. served as the CSO of Symantec for over five years. He has a special interest in digital data and human security. Arm is a customer of Tessian’s, and has deployed Tessian Defender,  Tessian Guardian, and Tessian Constructor. Consequently, Tim F. is not just attuned to the security risks associated with employees making mistakes, he understands how best to combat those risks. While you can listen to the full webinar and Q&A on-demand here, below are some of the key takeaways from Tim Fitzgerald. Where does risk really exist? Tim Fitzgerald: “It is very ‘sexy’ in security to talk about big hacking groups and use that as justification to invest in security. And there’s a lot of legitimacy behind that. But the other side of the narrative – which we spend more time on now than nation-state type threats – is how do we not do it to ourselves? Because now we’re more often dealing with avoidable events caused by predictable human error.” “I think, in general, not only should we be talking to our senior executives and boards more clearly about where real risk exists – which for most companies is the human layer – but we also need to be doing more to help these people combat the problem rather than just passing blame.” To err is human, but people are (generally) well-intentioned TF: “I very much chafe at the idea that we think of our employees as the weakest link. It underserves peoples’ intent and how they choose to operate. Rather than that, we try to take a look in the mirror and say ‘What are we not providing our employees to help them avoid these type of scenarios?’” “At Arm, we take the ‘people-are-people’ view. Not that they’re the weakest link; not that they don’t come with good intent; or that they don’t want to be good at their job; or that they take shortcuts just to get that extra moment of productivity. But, actually, everyone wants to do a good job and our job is to arm them with both the knowledge and the tools to be able to keep themselves secure, rather than trying to secure around them.” The role of a CISO is people-centric TF: “I view my job in human security as somewhere between a sociology and a marketing experiment. We’re really trying to change peoples’ behaviors in a moment. Not universally, not their personal viewpoints. But will they make the right decision in this moment to do something that won’t create security risk for us? Evolving that strategy relies not just on how we influence behavior in that moment of time, but actually, can we change their ethos? Can we make responsible security decision-making part of everybody’s job?” “Security is ultimately my responsibility. But, we very much rely on what we consider our extended security team, which is all of our employees. Our view is that they can undo all the good that we’ve done behind them to try to compensate for the risk that normal human beings create.” Security solutions should empower employees TF: “By far the biggest single challenge we have is Arm’s ethos around information sharing. We have a belief – that has proven to be true – that this level of information sharing has allowed Arm to be extraordinarily successful and innovative. There’s no backing up from that, and that represents a huge amount of challenge; that level of information sharing is quite difficult to manage. “Rather than saying people are an intractable problem and therefore we can’t conquer this, if we start thinking about how we can mobilize them as a part of our overall cybersecurity defense mechanism, it causes you to rethink whether or not you’re serving your populous correctly.”
Machine learning enables Human Layer Security TF: “What I liked about Tessian is that it gave us an opportunity to use the ML in the background to try and develop context about whether or not something that someone was doing was either atypical or perhaps just part of a bad process. Either way, we can get a sense of whether or not what they’re doing is causing us risk. It doesn’t require us to be completely prescriptive about what we’re looking for, but it allows us to learn with the technology – and with the people – what normal patterns of behavior look like and, therefore, intervene when it matters and not have to react every time an alarm goes off. “You have all this amazing context of what people are doing on email, which is where people spend most of their time and where most of the risk comes for most organizations. How can we turn this into more than just making sure someone doesn’t fat finger an email address or send sensitive files where they’re not supposed to go? Can we take the context that we’re gaining through how people are using email and create more of those moments in time to connect with them?” Tessian fits into a larger security framework TF: “We have a whole bunch of other mechanisms to protect against traditional insider threats – the people who are really acting against our best interest – but that instance is infrequent and high impact. The person who makes the mistake is high frequency, medium-to high-impact. We were getting hammered on that sort of stuff, which is why we came to Tessian.”
“When used correctly and in a finite environment or a finite data set, DLP solutions are very effective at keeping that data where it’s supposed to be and understanding movement in that ecosystem. When you try to deploy that broadly though…you start to run into the inability of the DLP system to understand where that data is supposed to be. Is this person supposed to have it based on their role and their function? It’s not a smart technology like that. You end up trying to write these very complex rules that are hard to manage.” The future of Human Layer Security TF: “Can we start to mesh together what we know about the technology and the machines with real human behavior? It’ll not only help us find those bad guys in our environments who we know are there, but also to get out in front of people’s behavior rather than reacting to it after it happens. That’s the holy grail of what this could become. To get – if not predictive – at least start leading us toward where we think risk exists and allowing us an opportunity to intervene before things happen.” Want to learn more about how Tessian helps Arm catch and stop accidental data loss with Tessian Guardian and prevent spear phishing attacks with Tessian Defender?

Ensuring Data Security under GDPR
02 December 2019
Coastal Housing Group is a not-for-profit social housing provider specializing in community residential properties. The business predominantly operates in South Wales, United Kingdom. In addition to residential properties, Coastal Housing has a robust commercial portfolio that focuses on mixed-use town center regeneration projects. Coastal Housing is protecting 250 employees with Tessian Defender and Tessian Guardian.
Protecting a bustling business Coastal Housing has provided housing opportunities to communities across South Wales since 2008. Mark Elias is Coastal Housing’s IT Infrastructure Manager. He understands how important data security is in the housing sector.  Coastal Housing handles and processes a considerable amount of sensitive information and utilizes multiple, complementary technologies to help keep this information protected. While the organization goes to great lengths to provide staff with the reassurance that they are conscientious about security, the IT team recognized that they could do more. With a growing mobile workforce and data regularly exiting the organization’s directly controlled network, the IT team wanted to see how machine learning could fortify their security stack. Tessian’s offering was exactly what Coastal Housing was looking for.
Staying vigilant under GDPR Tessian integrated seamlessly into Coastal Housing’s layered infrastructure. Tessian was up and running in a short period of time and was very easy for the IT team to understand. Having implemented Tessian Guardian, Coastal Housing can now prevent accidental data loss from misdirected emails, mitigating the impact of human error and helping IT teams control an unwieldy problem. Coastal Housing’s IT team deployed Tessian and educated employees about how the product works quietly in the background. With a low false positive rate, Coastal Housing’s employees liked the fact that when a warning did appear, it provided context on what had happened. Guardian accurately flags mistakes without disrupting their day-to-day workflow. Coastal Housing employees now feel assured that they won’t accidentally send sensitive information to the wrong destinations. In addition to the problem of accidental data loss, Coastal Housing’s IT team are acutely aware of how sophisticated spear phishing attacks are becoming. While employees are being as vigilant as they can be, it’s unrealistic to assume they will be able to spot a threat 100% of the time. Armed with Tessian Defender, Coastal Housing has secured their system from inbound spear phishing threats, protecting the organization from data being pilfered and systems being compromised.
Maintaining security while growing Coastal Housing understands that for security to be effective it cannot be static. As threats evolve, so must the technology designed to protect against them. Being a bustling business, Coastal Housing will continue to adapt and to respond to the ever-changing landscape. The organization will continue to focus on investing in platforms that are capable of doing the same.

Hill Dickinson is a leading commercial law firm with offices across the UK, Europe and Asia. With 850 employees worldwide, Hill Dickinson delivers advice and strategic guidance to businesses, organizations and individuals, advising on non-contentious advisory and transactional work for all forms of commercial litigation and arbitration. Hill Dickinson’s clients include multinational companies, major corporations, UK and foreign banks and financial institutions, public sector organizations, private individuals and professional bodies. Hill Dickinson is protecting 850 employees with Tessian Guardian and Tessian Enforcer. 
Improving client service with new technology As Director of IT and Operations at Hill Dickinson, Keith Feeny recognizes that the focus on security across the legal sector has increased dramatically over the past five years. Heightened client requirements and a tougher regulatory climate have made it necessary for law firms to take a more proactive approach to security. In particular, Hill Dickinson’s health practice works with some of the largest healthcare providers in the United Kingdom. Ensuring the security of sensitive data like patient records is a top priority. As Keith says, “Having big directories of sometimes quite similar names can increase the chance of an email being accidentally sent to the wrong person.” The need to mitigate these risks led Hill Dickinson to look for security products that wouldn’t restrict normal business, but which could effectively deal with the dangers of human error on email. With that goal in mind, Keith began to consider Tessian as a more intelligent solution.
Facilitating business as usual Hill Dickinson’s main priority when looking for an email security solution was finding a tool that would pose minimal interruption to business as usual. Keith was able to deploy Tessian firm-wide with minimal involvement from his IT team. Keith was particularly impressed with Tessian’s lack of false positives. Unlike other solutions which place a warning on every external outbound email, with Tessian “you’re getting 10 warnings out of 1,000 emails. The advantage of that is when people actually receive the warning, it gets their attention.” After deploying Tessian, Hill Dickinson now has indepth visibility on email security. As a result, Keith can easily surface intelligence on how many potential breaches have been avoided to the Executive and main LLP Boards, which enables strategic decisions to be taken with security in mind. Building a security culture for a mobile workforce Tessian has become a core part of Hill Dickinson’s security infrastructure. With more employees working from home and using personal devices, Hill Dickinson takes the risks of data loss and exfiltration seriously. Integrating with Tessian’s Gateway means that Hill Dickinson emails are covered on mobile devices as well as desktop computers, giving Keith additional peace of mind. Armed with Tessian’s Guardian and Enforcer filters, Keith is confident that Hill Dickinson is in a strong position to mitigate the risk of regulatory, financial and reputational damage caused by human failure on email.

The firm provides specialist legal advice in the areas of telecoms and media, competition law and regulation, corporate and finance, and disputes. Webb Henderson operates through its offices in Sydney and Auckland, serving clients domestically and globally from these locations. Webb Henderson is protecting 100 employees with Tessian Guardian, Tessian Enforcer and Tessian Constructor. 
Securing data and protecting customers As the partner responsible for Webb Henderson’s technology and security strategy, Ara Margossian believes that staying ahead of constantly changing threats is a principal security challenge for the firm: “Supply chain security has become a fundamental requirement for our clients, particularly those operating in sensitive industries and highly regulated sectors. Our clients are having very specific discussions with us about our security posture and data protection strategies. It’s never been more important that the work that we undertake for our clients is kept confidential and secure.” With clients increasingly seeing security as a top priority, it was important for Webb Henderson to ensure that their own security strategy was taking advantage of market-leading solutions. One of the biggest security risks that law firms like Webb Henderson face is the possibility of sensitive client information being exfiltrated to unauthorized recipients. Law firms primarily deal with unstructured data, making it difficult to solve the problem with rules-based Data Loss Prevention (DLP) solutions. The firm needed a product that would ensure Webb Henderson’s clients’ confidential data remained secure, which is what led the firm to Tessian.
Seamless integration into a layered system One of the firm’s top considerations when deciding to move forward was the intuitive nature of Tessian’s notifications and a positive user experience for employees. For Webb Henderson, it was important that any new technology was integrated smoothly so that the firm’s lawyers could focus on their work, rather than being distracted by new workflows and unfamiliar systems. With a low false-positive rate and minimal maintenance requirements, Tessian was a good fit with Webb Henderson’s firm’s objective of balancing the need for user education and visibility with the need for security to be robust and as unobtrusive as possible. An evolving partnership Tessian now forms part of Webb Henderson’s multi-layered approach to security and provides greater insight and control in relation to the risks faced by the firm from email communications. Using machine learning to anticipate and react to risky behaviors in real time has made a real difference for Webb Henderson. Tessian’s Guardian and Enforcer filters now play a critical role in the firm’s security stack, while Tessian Constructor is being used to add a further layer of protection.

Australia’s Oldest Law Firm Invests in Human Layer Security
28 September 2019
Allens is one of Australia’s leading commercial law firms with offices throughout Australia and 28 international locations through a global alliance with Linklaters. For almost 200 years, Allens has prided itself on providing excellent client service. The firm has worked with many of the world’s leading organizations both within Australia and abroad. Allens is protecting 1,100 employees with Tessian Defender, Tessian Guardian, and Tessian Enforcer. 
Looking for better data security oversight Allens is the oldest law firm in Australia, and has a proud heritage of supporting its clients through important matters. Bill Tanner is the Chief Information Officer at Allens and looks after endto-end IT delivery for the firm across Australia and South East Asian territories. Law firms like Allens receive sensitive company and client data on a daily basis. For Bill, ensuring the firm’s technical stack remains up to date and secure is a top priority. As Bill says, “Allens wants to help our people identify potential threats but also ensure our people don’t inadvertently expose our systems.” Searching for a solution that could simultaneously protect their people from security threats, while building awareness within the workforce as to how threats manifest on email, Allens turned to Tessian.
Mitigating inbound and outbound threats Tessian’s Guardian, Enforcer and Defender filters were seamlessly integrated into Allens’ security stack. After deployment, Bill and his team were able to immediately see the filters’ success in eliminating threats from both inbound and outbound emails. The high accuracy of the Tessian platform meant employees could still be protected while continuing their day to day business without interruption. Mail being sent to the firm has increased 57% over the past six months. Whilst there has been a 74% increase in the volume of mail rejections, this correlated with an 8% improvement in rejection rate. Mail-based attacks continue to rise, and attackers are getting more sophisticated with their techniques. Allens was looking to bolster its existing defences by providing additional context around the potential threats landing in employees’ inboxes. Tessian’s Defender module detects anomalous incoming emails in real time, delivering warnings to employees that both prevent the attack having any impact and educate them as to why the email looks suspicious. To Bill, Defender’s intelligent notifications “provide that context in the moment that is so important for our people.”
Creating a conscious security culture As data security threats continue to threaten the legal sector, it will be vital for firms like Allens to invest in cutting-edge technology to mitigate the risk of data loss and spear phishing attacks, and the potentially disastrous repercussions of data breaches. With Tessian’s filters protecting Allens employees in multiple territories, Allens has increased the protection of the sensitive data held by the firm as it continues to deliver the high standard of service the firm has provided for almost 200 years.

To Neil, it was vital for Man Group to continue looking beyond its existing security technologies like Data Loss Prevention. Aware of the potential risks and the limitations of legacy email security products, Neil and his team progressed with Tessian. Best-in-class security, without disrupting business After successfully deploying Tessian across the entire firm, Man Group’s information security professionals were quickly able to familiarize themselves with Tessian’s products and access detailed organizationwide security analytics through the Tessian dashboard. Tessian’s machine learning helped Man Group automatically identify and prevent inadvertent data loss over email while ensuring minimum disruption to employees at the organization. With a low false positive rate, Tessian’s warnings effectively minimized unauthorized emails and accidental data loss without disrupting people’s regular workflows. Staying vigilant in a changing environment With Man Group and other multinational investment managers having to deal with constantly changing regulatory and commercial environments, the need to invest in agile and customizable security solutions will only grow over time. With Tessian in place, Man Group can mitigate the risk of misaddressed and unauthorized emails without disrupting business as usual.

Moving past manual solutions Evercore is a firm with exceptionally high standards. That extends to deploying new pieces of software. In heavily transactional environments like investment banking, any downtime or performance issues caused by a new software product is potentially damaging. IT teams often cite ease of deployment as a main priority for new software. Chris Turek, Evercore’s Chief Information Officer, understands just how important it is to deploy new systems quickly and smoothly.
Incredibly simple, uniquely effective For Chris, the beauty of the Tessian platform lay in its administrative simplicity. When Tessian is installed on an email network, it begins analyzing historic email communications retroactively to learn what constitutes ‘normal’ behavior for each user. Within hours, Tessian was up and running, protecting Chris and Evercore’s employees against misdirected emails due to human error. Tessian has also been instrumental in targeting spear phishing emails generated outside the organization. What’s more, Tessian’s platform doesn’t require large sets of pre-labeled data or complex integration processes. The add-in can be installed by simply downloading a file, and it can be rolled out to users at the IT team’s discretion. As Tessian integrates directly with Microsoft Outlook, Office365 and G Suite, all major enterprise email environments are catered for.
