On May 12, 2026, Proofpoint announced the establishment of its MSP Platform, aimed at serving managed service providers (MSPs) and small to mid-sized businesses (SMBs) in North America. This initiative follows Proofpoint's acquisition of Hornetsecurity in December 2025, which laid the groundwork for its MSP-focused offerings. The new platform, Proofpoint 365 Total Protection, provides a unified, AI-driven security solution for Microsoft 365, designed to simplify security management for MSPs. The platform aims to reduce complexity and costs by consolidating multiple vendor relationships into a single solution. Proofpoint has partnered with Pax8 to enhance its channel ecosystem, allowing partners access to comprehensive Microsoft 365 security services. The launch is part of a broader trend among cybersecurity vendors, including SonicWall and Palo Alto Networks, to streamline offerings for MSPs. This shift addresses the growing demand for bundled, SaaS-based security solutions in the midmarket sector.
