## Summary

Hornetsecurity by Proofpoint announced a suite of AI‑focused security updates for Microsoft 365 that will roll out in Q4 2026. The company says the new features are designed to give organisations and managed service providers clearer visibility into permission and sharing risks, and to make AI‑powered email assessments easier to interpret.

CEO Daniel Hofmann explained that AI adoption amplifies existing security gaps, so the firm is adding a 365 Permission Manager that maps access across SharePoint, OneDrive and Teams, an AI Cyber Assistant in the Control Panel for centralised management, and adaptive security awareness training that now extends into Microsoft Teams. The goal is to let customers build a stronger security foundation before deploying AI tools.

The announcement positions Hornetsecurity’s next‑gen portfolio as a bridge between everyday collaboration tools and the emerging AI workload, aiming to reduce the chance of over‑broad permissions or unclear sharing settings that could be exploited by AI‑driven processes.
