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.

Better Email Security with Intelligent Technology
11 April 2019
JTC is a publicly listed, award-winning provider of fund, corporate and private wealth services to institutional and private clients. Founded in 1987, JTC have c.600 people working across their global office network and are trusted to administer assets of c.US$85 billion. Putting clients at the heart of the business and developing and investing in talent have been key to JTC’s growth. JTC is protecting employees with Tessian Guardian, Tessian Enforcer and Tessian Constructor.
A shared journey There is a natural fit between JTC and Tessian. Tessian’s machine intelligent approach is revolutionising the way companies prevent against data loss is well suited to JTC’s forward thinking attitude, and entrepreneurial mindset. This natural fit was demonstrated early on in the relationship between JTC and Tessian. In the space of one month JTC listed on the London Stock Exchange, chose Tessian as their machine intelligent based email solution, and Tessian secured their $13 million Series A funding round led by Balderton and Accel. “Enterprises must contend with a vast array of scenarios where email can be used or abused to cause severely damaging yet avoidable incidents for the business,” says Tim Sadler, CEO and co-founder at Tessian. “This is especially true for JTC and other firms that are dealing with highly sensitive financial information. Machine intelligence can give organisations a way to learn normal sending patterns and automatically step in to check or prevent something that appears out of character or breaks policy. This mitigates any interruption to innocuous email use, meaning employees and IT teams won’t have to deal with needless, time-consuming administration.” JTC’s attitude to data protection, coupled with increasing regulatory demands and its higher profile following its listing on the LSE Main Market, catalysed them to seek out a solution that matched their forward-thinking attitude and appreciation for a seamless user experience.
The problem JTC’s innovative IT team had been actively seeking a machine intelligent solution to assist in remaining competitive, innovative and at the forefront in the financial services sector. This led JTC to identify that the risk of sensitive information being inadvertently sent to the wrong recipient or to unauthorized accounts as a priority. After looking around the market, JTC dismissed the rule-based solutions, due to unacceptably high user interruption and resource hungry administration and management, and opted for Tessian’s unique approach of intelligently preventing misaddressed emails, and unauthorized emails through machine learning. JTC also recognised spear phishing as a key inbound risk vector. In assessing the risk, they identified that, whilst existing rule-based email security controls are adequate for preventing weak-form impersonation spear phishing attempts, the risks of highly targeted strong-form impersonation spear phishing attacks were increasing. To combat this risk, JTC opted for Tessian’s Defender module which uses machine intelligence and an understanding of historical email relationships to prevent strong-form impersonation spear phishing attacks. The solution Explaining the reason for his firm’s adoption of the technology, JTC’s Chief Information Officer, Adam Jeffries says “Tessian stands head and shoulders above other providers, it requires no admin and creates zero disruption for employees. The technology directly helps our business in solving critical problems and we were very impressed with this. “IPOs are one of the most sensitive times for organisations and a single misaddressed email could put the entire process in jeopardy. For us, it made complete sense to invest in a tool like Tessian to stop the very apparent risk of email data loss.” Deployment The Outlook Add-in was straightforward to implement and fully installed to all users within a week. The seamless integration was then completed by the Gateway solution to provide full coverage across the organisation and ensure all our mobile workers had the protection available to them. Success JTC continue to find Tessian’s reporting to be fantastic, allowing them to realise and demonstrate to the various boards immediate value. Tessian’s ease of use allowed JTC’s GDPR team to actively prevent breaches whilst ensuring minimum impact on users in the form of Outlook pop-ups. The team found Tessian intuitive and easy to use, fitting seamlessly into their existing workflow with no disruption to users. They appreciated the speed and accuracy of the machine learning.
