As of mid-May 2025, there is no confirmed information supporting claims that Proofpoint plans to acquire Hornetsecurity for over $1 billion. Speculation about such a deal appears to be unfounded, with no substantial evidence from reliable sources backing these rumors.
In fact, Proofpoint, known for its cybersecurity and compliance solutions, was acquired by the private equity firm Thoma Bravo back in August 2021. This significant deal was completed for approximately $12.3 billion, illustrating the market value and strategic interest surrounding Proofpoint's offerings at that time.
Hornetsecurity continues to operate successfully within the email security sector, emphasizing its focus on advanced threat detection and management. Established as a key player in the industry, its strategies and innovations in email protection are well recognized. However, Reuters reported that there isn't any verified development regarding its acquisition by Proofpoint.
