A Good Start But....

Use Cases and Deployment Scope

Tessian was put in place to better assist users with avoiding account compromises and reduce our security exposure through email. Tessian was used across the organization for every user.

Pros

  • Clear alerts within emails to provide context to emails.
  • Fairly easy to deploy across the organization.

Cons

  • The Outlook Add-In broke several systems during use.
  • There are many changes to the account reps and engineers assigned to us. As a result, we lost touch with Tessian.
  • Lack of knowledge and help from Support during times when the Add-In was disrupting users.

Return on Investment

  • Early ROI due to users having more information about potential scams.

Usability

Easy but solid catch-all solution for g-suite email security

Use Cases and Deployment Scope

Solid plug-and-play solution for email security, is specifically nice with g-suite since the built-in email security tools are pretty limited. Very intuitive and simple interface, and feels like it could be used by someone who's not hard technical without much issue. Has some pretty simplistic DLP functionality built-in which is a nice bonus as it gives you some basic tools to work with.

Pros

  • simplicity
  • plug-and-play
  • low-hassle

Cons

  • maturity
  • transparency as to how detections work
  • power-user features
  • API

Most Important Features

  • easy
  • fast
  • decent coverage
