How are IT and security leaders using Tessian's technology to secure email?

Before we adopted Tessian’s technology, we didn't believe we had any problems with misdirected emails. After a pilot, we realized that was only because these issues weren’t being reported. We can see ROI in one email.”

Andrew Cheung, Partner & General Counsel, Dentons

There are complex solutions to a number of the security challenges we face, but the best chance we have to protect ourselves is simply doing the fundamentals properly. Tessian is now part of our fundamentals, and a part that I wish we had all along.

Tim Fitzgerald, CISO, Arm

“Tessian proved its value after a few weeks of being deployed firm-wide. For the first time ever, we now have visibility and control over inadvertent data loss through misaddressed emails and information being sent to unauthorized email accounts.”

Neil Wellard, Head of Information Security, Man Group
