ICYMI: Proofpoint to acquire email security rival Tessian

US cybersecurity and compliance company Proofpoint Inc announced this week that it has entered into a definitive agreement to acquire email security rival Tessian, which applies AI to automatically detect and guard against accidental data loss and evolving email threats.

With the acquisition of Tessian, Proofpoint says that it will enhance its threat and information protection platforms by adding powerful layers of AI-powered defense that address risky user behaviours, including misdirected email and data exfiltration.

Darren Lee, executive vice president and general manager of the security products and services group at Proofpoint said: “By combining Proofpoint’s best-in-industry data, detection stack, and efficacy with Tessian’s advanced behavioural 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.”

The acquisition is expected to close in late 2023 to early 2024, subject to customary closing conditions, including any required regulatory approvals.
