Coach Tessian’s machine learning uses twelve months of historical data from Microsoft and/or Google APIs to establish a behavioral baseline for each user. Tens of thousands of events over email create a strong foundation for normal vs. abnormal communications.
Behavioral Flag Examples:
- Display name change
- Irregular Employee Comms
- Unusual IP Addresses
Tessian’s machine learning identifies unusual text in images, QR codes, URLs, subject headings, body text, and inside of email attachments for potential threats. Hundreds of data points within each email are used to determine if the email is safe, malicious, or needs review. We use each of these data points to prevent similar attacks from bypassing defenses.
Content Flag Examples:
- Suspicious QR Codes and Images
- Password Reset Requests
- Urgent/Fraud call to action
The Tessian platform includes third party threat feeds and threat data from our customers to improve security across the network. Within minutes, Tessian can add malicious domains, urls, IPs, email addresses and file hashes from any source to prevent email based attacks. When Tessian flags emails as threats, or similar attachment hashes are seen in attacks within our network, we detect the same threat across the entire Tessian community automatically.
Threat Network Flag Examples:
- Flagged IP, URL, file hash
- False negative reports
- Tessian threat hunting
Tessian is built to augment security from your email provider, by stopping advanced phishing attacks and protecting sensitive data on email. With native API integrations to Microsoft and Google, Tessian deployed in less than five minutes.

Tessian’s risk insights offers a user and group based view of risk from email based threats, calculated based on the risk drivers below:
Phishing Attacks
Measures the risks associated with employees being tricked by phishing attacks, including credential theft, business email compromise, data loss, and malware.
Data Exfiltration
Data Exfiltration measures the risk associated with employees sharing sensitive data to non-business accounts outside of the organization
Accidental Data Loss
Measures risk associated with employees accidentally leaking sensitive data outside of the organization
Data Sensitivity
Data Sensitivity risk driver identifies those employees who day-to-day handle more sensitive data than others, and is an important factor to consider when thinking about protecting the human layer; those who have access to and handle more sensitive data require greater protection.
Security Awareness Risk
Measures risk associated with employee security awareness, engagement, and compliance. A higher score represents more risk associated with lower employee security awareness.
