Product Walkthrough: Securing Microsoft Copilot with Reco
Summary: Reco, a SaaS Security platform, describes a six-part approach to securing Microsoft 365 Copilot, including analyzing user prompts against user identity and role, flagging sensitive keywords such as "SSN" and "credit card," and applying NLP to catch intent behind queries that avoid obvious terms. The platform also monitors Copilot's responses and file-sharing events, checks sharing permissions, integrates with Microsoft Purview sensitivity labels, and compares prompts against known attack techniques from MITRE ATT&CK using vector similarity matching.
What you should know: The article states that without proactive controls, every file in an organization could be accessible via Copilot, and an attacker could use it to locate sensitive files or map out IT infrastructure and vulnerabilities without manually searching systems.
