Proofpoint partners will gain new cyber defense solutions with the company's acquisition of Tessian.

Tessian uses advanced artificial intelligence (AI) to automatically detect and guard against both accidental data loss and evolving email threats.

The acquisition should close in late 2023 to early 2024, subject to customary closing conditions, including any required regulatory approvals. With the acquisition of Tessian, Proofpoint will enhance its threat and information protection platforms by adding layers of AI-powered defense that address risky user behaviors, including misdirected email and data exfiltration.

“Far too often, human errors with email lead to organizations putting their own and their customer’s data at risk, breaching industry and data protection regulations and losing mission-critical intellectual property,” said Darren Lee, executive vice president and general manager of Proofpoint's security products and services group. “By combining Proofpoint’s best-in-industry data, detection stack and efficacy with Tessian’s advanced behavioral and dynamic detection platform, we can provide our customers with world-class defense and instant protection. Proofpoint channel partners can quickly bring value to their customers with these new, easy-to-deploy solutions that integrate natively with Microsoft 365 and Google Workspace.”

Proofpoint Partners to Get Enhanced Offering

More than nine in 10 organizations have dealt with a data breach caused by an end-user error on email, according to Proofpoint. Using behavioral understanding and machine learning (ML), Tessian's AI-powered email security platform will enhance Proofpoint’s email data loss prevention (DLP) offering by addressing accidental data loss and malicious insiders through its Microsoft 365 and Google Workspace deployment.

Tessian solutions include:

  • Tessian Guardian, which protects sensitive data, helps customers meet regulatory compliance and confidentiality agreements, and eliminates the risk of reputational damage by preventing misdirected emails and mis-attached files.

  • Tessian Enforcer, which automatically protects against data exfiltration and safeguards intellectual property without predefined rules or deny lists.

  • Tessian Defender, a context-aware, AI-based email defense that detects and prevents the full spectrum of email attacks, while providing end users with in-the-moment contextual warning banners to help them decide whether an email is safe.

Tessian’s solutions should become part of the offering that Proofpoint partners can sell upon the closing of the acquisition.

“Our longstanding vision to secure the human layer has been the driving force behind our innovative platform offering inbound email security, as well as outbound data loss prevention,” said Tim Sadler, Tessian's CEO. “By joining forces with Proofpoint, we can empower organizations to further improve their email security posture, reduce the risk of data breaches, and lighten the workload on their security teams.”
