In May 2025, Proofpoint announced the acquisition of Hornetsecurity, which completed in December 2025. This move brings together two well-established cybersecurity providers and strengthens Proofpoint’s offering for small and mid-sized businesses.
Hornetsecurity is known for its integrated “365 Total Protection” platform, which combines email security, Microsoft 365 backup, compliance, and security awareness into a single, streamlined solution designed to simplify protection and reduce operational complexity.
For customers currently using Proofpoint Essentials, there are no immediate changes—services continue as normal and remain fully supported. However, the acquisition signals a clear direction of travel, with Hornetsecurity expected to play a central role in Proofpoint’s future offering for businesses like yours.
Over time, this is likely to mean enhanced functionality, more integrated security capabilities, and a more unified platform experience. We will continue to monitor developments closely and provide guidance to ensure you benefit from any improvements, with a focus on maintaining strong protection, reliability, and ease of use.
