Tessian gives us an opportunity to take a proactive step to prevent bad things happening in the first place

Rob Hyde, CISO, Schroders

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.
