Proofpoint Inc., a leading cybersecurity and compliance company, today announced it has entered into a definitive agreement to acquire Tessian, a leader in the use of advanced AI to automatically detect and guard against both accidental data loss and evolving email threats. The acquisition is expected to close in late 2023 to early 2024, subject to customary closing conditions, including any required regulatory approvals.
Balderton first invested in Tessian back in 2018, co-leading the company's Series A alongside Accel.
Proofpoint protects organizations against social engineering attacks by applying award-winning AI and large language models (LLMs) to block threats and provide real-time threat insights. AI-based detection has proven to be notably effective in identifying threats targeting people, such as email fraud and supplier-based attacks, and preventing data loss due to negligent or malicious actions. With the acquisition of Tessian, Proofpoint will enhance its threat and information protection platforms by adding powerful layers of AI-powered defense that address risky user behaviors, including misdirected email and data exfiltration.
Our long-standing 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. 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.
More than nine in 10 organizations have dealt with a data breach caused by an end-user error on email. Using behavioral understanding and machine learning, 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 seamless Microsoft 365 and Google Workspace deployment. Tessian solutions include:
Tessian’s solutions are expected to become part of Proofpoint’s offering upon the closing of the acquisition.
