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. With clients increasingly challenging the legal sector on data protection and cybersecurity, Tessian and Webb Henderson plan to continue to work together to mitigate risks that arise from human error to ensure the security and safety of Webb Henderson’s data and its reputation.

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.

Data Loss Prevention in Healthcare: A Serious Business
11 June 2019
Laya Healthcare members have access to some of the most innovative health insurance benefits and services in the Irish health insurance market. Working with over half a million customers, its brand promise, Looking After You Always, represents laya healthcare’s member-centric approach, which is fundamental to its vision and values. Part of global insurer AIG since 2015, Laya healthcare also offers life and travel insurance policies. Laya Healthcare is protecting 550 employees with Tessian Guardian.
Security in healthcare: a serious business Health insurance is an intensely specialized industry and can be fragmented from a technology perspective. Significant amounts of information are constantly transferred between different practitioners, hospitals, other insurers and partner organizations. As one of Ireland’s largest health providers, Laya healthcare deals with extremely sensitive information. Ian Brennan, Director of IT at laya healthcare, and his team go above and beyond to ensure human error doesn’t contribute to breaches or put individuals’ data at risk. Ian is responsible for overseeing Laya healthcare’s security and privacy. Analysing their security data, he established that particular email productivity functions like Autocomplete were actually contributing to errors being made by people. As Ian says, “We always want to save our team time, but unfortunately there are negative consequences to these efficiency-led features too.” Ian needed to find a way to eradicate the possibility of these errors without disrupting employees’ productivity on email.
Minimizing disruption for the workforce Laya healthcare’s existing Data Loss Prevention tool was catching most mistakes being made by people on email. However, certain limitations meant that Ian was looking for a more intelligent solution that learned from users’ behaviour, and which required minimal time investment from the IT department. In Ian’s experience, “there are a million tools that say they’ll do exactly what I need. But if I need a performant product that runs unobtrusively when it’s not doing its job, there aren’t many solutions that really fit the bill. Ian is sensitive to the knock-on effects on his IT team when software doesn’t work as intended. Since Tessian deployed the Guardian product for Laya healthcare, it has needed minimal “care and feeding”, as Ian says, requiring no IT input to make sure Guardian was learning as expected. This freed his team up to tackle higher-value work. “I’ve seen very few products as light on IT admin as Tessian.”
Moving beyond rule-based systems Ian was eager to take advantage of Tessian’s ability to learn from employees’ behaviours, identifying which email conversations were ‘business as usual’ and which emails needed flagging. Ian is confident that leveraging Tessian’s machine learning will reduce overhead for his team and the wider business in the coming years. “As rule-based systems expand in complexity, the maintenance and service requirements often increase too. We anticipate that Tessian will scale much more smoothly.” Insurance companies are confronting a changing security climate. “People are now much more switched on to their rights as individuals, and security risks are always evolving too.” Tessian and laya healthcare will continue to work closely together in the coming months and years, helping eradicate human errors on email and helping laya healthcare members get the topclass service they deserve.

Tackling Spear Phishing when the Stakes are High
11 June 2019
Polarcus is the world leader in offshore geophysical services. Its fleet of green, hightech vessels conduct explorations from pole to pole, producing seismic survey data for global clients. Headquartered in Dubai, the company is listed on the Oslo stock exchange. Polarcus is protecting 350 employees with Tessian Defender. 
The spear phishing paradox Spear phishing is a relatively new and very different kind of security threat. For decades, spam and bulk phishing attacks have relied on unsophisticated mass messaging, effectively hoping that one or two people out of thousands don’t pay attention and make elementary mistakes. Spear phishing, by contrast, is far more malicious. Inbound emails targeting specific people, using social pressures to imply urgency, are a much more challenging threat for legacy security products. Erik Ruis joined Polarcus as Head of IT in early 2019. At that point the company was working out how to address sophisticated threats that could bypass its existing security infrastructure. He comments, “Threats like data theft and systems takeover can start from a single spear phishing email. Making things more complicated, companies in our sector have become targets for attackers seeking financial gain or trying to make an environmental or political statement.” This set of circumstances led Polarcus to Tessian.
Helping users make better judgments Spear phishing techniques like domain impersonation (when an attacker changes, for example, ‘tessian.com’ to ‘tesssian.co’ in order to trick a user into thinking an email is coming from a colleague) pose enormous risks to organizations. To effectively combat these threats, busy email users needed to understand in real time why an email might be suspicious. Defender, Tessian’s product built to combat spear phishing threats, was the natural solution. In Erik’s experience, “When you show someone a phishing email and tell them it’s an impersonation, they are still sometimes unable to understand why it’s fake.” This underscored the benefits of a product that leverages machine learning to automatically provide contextualised warning messages to users, a fundamental part of the Tessian offering. Now, Erik says, “we don’t get many alerts from Tessian, but when they happen people definitely notice them and benefit from them.”
What the future holds As Polarcus continues to innovate, Erik will keep looking for intelligent products that can tackle issues to do with human behavior on email, such as data exfiltration. The key will be identifying solutions that focus on “patterns of behavior, rather than rules.” In the meantime, attackers trying to circumvent legacy rule-based systems means that for Erik, “as perpetrators become more creative and more sophisticated over time, I expect Tessian’s products to keep adding even more value.” 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.

Focusing on Security Basics with Game Changing Technology
11 June 2019
Arm technology is at the heart of a computing and connectivity revolution that is transforming the way people live and businesses operate. Together with 1,000+ technology partners, Arm is at the forefront of designing, securing and managing all areas of computing, from the chip to the cloud. Arm is protecting 6,000 employees with Tessian Defender and Tessian Guardian. 
Building a human layer security culture “Humans will make mistakes.” That’s the blunt assessment of Arm CISO Tim Fitzgerald. Tim joined Arm in 2017 after spending years working on IT and information security at KPMG and Symantec. Since being acquired by Softbank in 2016, Arm has been investing significantly in the organization’s growth. On joining Arm, Tim kicked off an ambitious plan to improve his workforce’s understanding of security risks, while retaining a “high-trust” culture that emphasises “sharing, communication and collaboration as the basis of Arm’s success”. When Tim first began speaking to Tessian, he was seeking a more intelligent way to respond to isolated incidents of data loss that resulted from people not having enough salient information surfaced for them in real time. “Getting the fundamentals right”, for Tim, meant looking at the most prominent channels of communication and catalyzing change by focusing on the most important threat vectors within these channels. That meant looking at email, and particularly at how people behave – and slip up – on email.
Tailored real-time threat detection Over an initial proof-of-concept period, Arm straight away began seeing results. Thanks to Tessian’s ability to retroactively analyze historic email data, Arm was “immediately able to look back and pinpoint particular events that could have been avoided with Tessian’s software. That was a huge influence in our decision to move forward.” For Tim, Tessian’s reinforcement of best practice through delivering crucial contextual insight – giving people a beat to stop and think – is critical. “The value for us is that we’re effectively retraining the organization to look again at how they’re interacting with email in real-time.”
Eradicating ‘garden-variety’ vulnerabilities Under Tim’s leadership, Arm is continuing to invest in its security infrastructure by focusing on its people, and on flawlessly executing the basics of information security. In Tim’s view, “The ugly truth is that most threats to organizations stem from ‘garden variety’ vulnerabilities, and that includes humans.” Today, Tessian protecting employees from human error on email is a crucial part of Arm’s security strategy. Sometimes, focusing on the basics is the most important thing you can do.

Human-Centered Cybersecurity in a Historic Industry
11 May 2019
North P&I Club (North) is a leading mutual maritime liability insurer based in Newcastle upon Tyne with regional offices and subsidiaries in Australasia, China (Hong Kong and Shanghai), Greece, Ireland, Japan, Singapore and the USA. North’s IT department embraces modern technologies by creating leading-edge solutions to support over 350 staff across the globe on a 24/7 basis, enabling the shipowners we insure to trade with confidence. North is protecting over 350 employees with Tessian Guardian and Tessian Enforcer.
The voyage beyond policy and training “As you can imagine, in the shipping sector a lot of business is conducted on email.” James Holmes, Chief Information Officer at marine insurer North, has a broad range of priorities to tackle in his role. Until adopting Tessian, North had principally aimed to educate employees through policy and training initiatives. James saw that there was an opportunity for technological solutions to also play their part: “We have to acknowledge that people are going to make mistakes – we are human, after all – but at the same time we have to mitigate errors as much as we can.” James was made aware of Tessian’s software through another Tessian customer, and was immediately impressed by the prospect of intelligently being able to identify misdirected emails before they happen. Insurance companies control many kinds of sensitive data, and James wanted to make sure data wouldn’t be put at risk because of human error. North’s IT team scoped out the market and found that Tessian would be the platform that best served the company’s needs. North’s cross-departmental Information Security Committee approved, and gave the green light for James’s team to deploy Tessian.
Better email security with intelligent technology James was eager to take advantage of the way Tessian impacts people’s behavior in the moment, prompting them to think carefully about potentially taking a dangerous action on email. “It’s about empowering people to make decisions having all salient information to hand.” Since rolling out Tessian across the business, North has seen a number of employees receiving Tessian alerts and, as a result, double-checking emails to ensure mistakes are not made. Digesting Tessian’s reports on people’s alerts helps James to quantify the Guardian filter’s impact. “People can react in the moment to Tessian’s notifications and make the right decision for themselves and the business.”
Encouraging cybersecurity oversight across the business With more people working from home and using different devices to get work done, it’s important for companies in all industries to understand where new threats may emerge. James says, “We all know that personal addresses are more susceptible to hacking. Having technology that reminds people of the dangers of inappropriate data transfers is incredibly useful.” Today, North is in the process of improving its data loss prevention capabilities by bringing in Tessian’s Enforcer filter. Enforcer identifies when sensitive data is being transferred out of an organization to personal or unauthorized addresses. Because of Enforcer’s importance when it comes to regulatory alignment, North’s risk and compliance team will take responsibility for managing the new filter. Shipping is one of the oldest trades in the world, and marine insurance is moving quickly as a sector. By embedding best-in-class technology across the company and building out the organization’s suite of Tessian products, James is orienting North for longterm success.

Dentons is a global law firm driven to provide clients with an innovative and competitive edge. As the 8th largest law firm in the world by revenue and the world’s largest law firm by number of lawyers, Dentons is a BTI Client Service 30 Award winner. Dentons is protecting 1,300 employees with Tessian Guardian and Tessian Enforcer.
Mitigating data loss risks As a Partner and General Counsel at Dentons, Andrew Cheung understands the importance of finding the right solution when faced with a complex problem. Law firms like Dentons encounter vast amounts of sensitive information on a daily basis. Ensuring that proprietary client data remains secure is a top priority for Andrew and the firm as a whole. The risks of allowing data to leak are serious. Commercial, regulatory and financial penalties are becoming more severe, and law firms, which aggregate sensitive data from many individuals and businesses, are at particular risk from sophisticated attacks.
Better visibility into complex systems Complex enterprises may lack oversight and control over every piece of information sent to unauthorized or misaddressed accounts. By applying machine learning to historic email data, Tessian learns about employees’ unique relationships with their colleagues and other contacts. After deploying Tessian’s Guardian and Enforcer modules, Andrew was able to benefit from in-depth visibility into Dentons’ email security. Right from the partnership’s pilot phase, Andrew saw return on the firm’s investment in Tessian.
Delivering growth, staying secure Whether it’s malicious behaviour such as an employee forwarding company proprietary data to a personal account, or a well intentioned employee sending a file to a personal account to work from home, data loss from unauthorized or misaddressed emails will continue to expose law firms to significant risk. With Tessian protecting Dentons’ people, data and systems, Andrew and the wider firm are confident that the firm can deliver growth while remaining protected from advanced security vulnerabilities.
