Enhance Microsoft 365 Security Capabilities With Tessian

Microsoft + Tessian

Working together to strengthen email security and stop advanced attacks

Seamless integration with Microsoft

While Microsoft 365 offers built-in email security, providing a baseline against spam and malware. Tessian works alongside Microsoft, offering complete protection leveraging Microsoft’s Graph API and Office Add-In deployed together as Tessian’s M365 Integration. This integration gives enterprises more robust email security without needing a gateway or client-side software. Microsoft + Tessian offers an additional layer, providing comprehensive protection against advanced threats and insider risks on email

Protection for Microsoft Office

Simplify and Modernize Your Technology Stack

Tessian Cloud Email Security Platform is a fully automated platform that closes critical security gaps in the enterprise security stack.

Automatically prevent advanced email threats

While Microsoft 365 will scan for known malicious payloads such as links and attachments, Tessian combines behavioral intelligence modeling, threat intelligence and deep content inspection to automatically detect and prevent the full spectrum of advanced email attacks that legacy email defenses miss. When a threat is detected and prevented, Tessian notifies the end user to warn them of the threat.

Unburden overwhelmed SOC teams

Integration with Microsoft 365 is seamless and easy for time-poor SOC teams. Tessian does the hard work by automating incident triage and remediation. Tessian automatically quarantines known email threats and detects and prevents unknown email threats that evade Secure Email Gateways, significantly reducing admin time.

Remediate with speed

Efficiency gains are further realized in the SOC by automating incident triage and remediation – significantly reducing admin time.
Quarantine, clawback unsafe emails from users’ inboxes, update deny lists and remediate burst attack campaigns with a single click. Or integrate with a SIEM. With Tessian’s no black-box rule, a clear explanation is provided for every action taken. Deeper integrations with Microsoft allow security teams to sync user groups, view emails directly within the portal and more.

Non-disruptive, in-the-moment security awareness coaching

Emails with the highest probability of being malicious are automatically quarantined for inspection and approval by a Security Analyst. For emails with a lower probability of being malicious, Tessian helps build a smarter security culture using in-the-moment security awareness coaching. End-users receive simple explanations of potential risks and are able to self-remediate, which also reduces security teams’ workloads.

Gain visibility into email risk

Our integrations with Microsoft allow security teams to sync user groups and view emails directly within the portal. Security and Risk Management leaders also gain greater visibility into risk levels and drivers at end-user, department, and company level – enabling them to take targeted actions to reduce risk.

Intelligent email security beyond advanced email threat prevention

In addition to the advanced email threat prevention, Tessian offers industry leading email data loss prevention for accidental and malicious data loss on email including mitigation against:
  • Insider threats
  • Data Exfiltration
  • Misdelivered emails and attachments
No rules or policy configurations needed. Customize warning messages, on-demand policy enforcement capability, allowing full control of outbound email traffic.
