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.”
