The Challenge:


Limited Visibility:

96% of all data breaches start with an email, with the majority of organizations having limited visibility over email phishing attacks. Most threat visibility tools only offer point-in-time insights.


Risky Legacy Tools:

Organizations that rely on legacy, rule based email security tools like secure email gateways (SEGs) have no ability to detect and prevent advanced email threats.


No Advanced Protection:

Human mistakes are the number one cause of data loss. Poor visibility into data loss events equals compliance risk. Lack of visibility into threat actors limits remedial measures and results in a broken compliance enforcement model.

The Tessian Advantage:


Comprehensive Protection and Visibility:

Detect and prevent advanced email security threats and view them in a single dashboard for easy remediation. Get comprehensive protection and insight into advanced phishing attacks, zero-day threats, accidental data loss, and insider threats.

Third-Party Integrations for Closed-Loop Security.
Tessian can ingest data through an API and on-premises email platforms and can integrate with third-party SIEM and SOAR tools to centralize and triage security events.

What Can You Do With Better Threat Visibility?


Identify at-risk employees (most attacked, most phished, data exfiltrators, non-compliant actors) in your organization and take additional security measures to protect them.

Behavioral intelligence modeling, powered by machine learning means that Tessian can automatically identify attack trends early, so that organizations are not caught unawares after a breach.

In-the-moment warnings educate employees about the threat, remind them of security policies and help nudge them towards safer behavior, empowering them to be your strongest security defense.

Continuous protection for your employees that enables you to drive down risk in your organization.
