Proofpoint to Buy Hornetsecurity in $1 Billion Deal

Proofpoint Inc., a major player in the cybersecurity sector, has agreed to acquire Hornetsecurity, a European cloud security firm based in Germany, in a deal valued at more than $1 billion. The acquisition is expected to close later this year, pending regulatory approvals and customary closing conditions.

Hornetsecurity specializes in safeguarding companies from cloud-based threats, with a particular focus on securing Microsoft 365 environments. Its offerings include email security, backup, and compliance tools designed to help organizations mitigate risks associated with the popular productivity suite.

The acquisition is poised to bolster Proofpoint’s presence in the European market and expand its portfolio of cloud-based security solutions. As enterprise reliance on Microsoft 365 continues to grow, the deal underscores Proofpoint’s strategy to address evolving threats in cloud collaboration platforms.

The companies have not disclosed additional terms of the agreement. Upon completion, Hornetsecurity will become part of Proofpoint’s expanding suite of cybersecurity services.
