**Tessian Enforcer**: According to the vendor, this feature automatically stops sensitive information from leaving the organization's environment via malicious or negligent data exfiltration. It prevents non-compliant activity and safeguards sensitive information.

**AI-Based Email Threat Detection**: The vendor states that this feature utilizes AI and machine learning to learn normal vs. anomalous behavior from historical email data. It quantifies human risk scores for security teams to prioritize potential threats and provides recommended actions to improve security for employees.

**Automatic Threat Prevention**: According to the vendor, this feature automatically detects and prevents advanced email security and Data Loss Prevention (DLP) threats. It provides real-time protection without requiring manual intervention from security teams.

**In the Moment Security Coaching**: The vendor claims that this feature notifies employees with contextual warning messages when threats are detected in their emails. It uses employee feedback to improve behavioral intelligence models and customizes warnings with the company logo and specific wording.

Secure Email Gateway Software

Tessian Cloud Email Security Platform is an outlook solution that looks and learns users behaviors. It will alert a user to a suspicious inbound email and point specifically to the items that are questionable, not only protecting the user, but providing real-time training to them in their own Inbox. It also monitors outbound communications and will alert if a user mis-directs an email and recommend suggestions

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.

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

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.

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

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.
