Tessian was so easy to deploy and has been incredibly low-maintenance. It’s not a tool we have to worry about keeping up and running from an infrastructure perspective. It’s one less thing the security team has to worry about. That was and continues to be a huge selling point for us.

Tessian works very nicely in concert with our other layers of defenses, like phishing awareness training. The benefit of the platform is that it provides continuous awareness, and introduces a mandatory pause.
Ian Schneller
