Proofpoint signs definitive agreement to acquire Tessian

Cybersecurity firm Proofpoint Inc. is set to acquire Tessian, a leading AI email threat detection company. The deal will enable Proofpoint to enhance its threat and info protection platforms, countering risky user behaviors such as misdirected emails and data exfiltration. The acquisition, expected to close between late 2023 to early 2024, will bolster Proofpoint’s Microsoft 365 and Google Workspace defenses and reduce security teams’ data breach detection and remediation times.
