Risk & Security

Risk and security governance is about reducing the exposure that grows as content, workspaces, and AI assistants multiply across Microsoft 365. Oversharing, stale access, and unprepared Copilot rollouts can turn everyday collaboration into data leakage. Rencore Governance detects oversharing, reviews who can reach sensitive information, and confirms Copilot readiness before deployment, so organizations can adopt new capabilities confidently without expanding their attack surface.

Every new workspace, shared file, and AI assistant adds convenience and, potentially, risk. Risk and security governance is about keeping that balance in check: enabling collaboration and Copilot while making sure sensitive information stays with the people who should see it. The outcome you want is confident adoption, where new capabilities do not quietly widen your attack surface.

The outcome: exposure under control

Security in Microsoft 365 is largely a question of who can reach what. When permissions accumulate and broad sharing links spread, the estate becomes harder to reason about. Bringing oversharing and access into a single, reviewable view means you can act on real exposure rather than react to breaches after the fact.

The risks of unmanaged sharing and AI

Oversharing is the quiet threat that Copilot makes loud. An assistant that can read everything a user can read will surface whatever has been overshared, turning latent permission sprawl into visible data leakage. Stale access, anonymous links, and site-wide permissions compound the problem, and unprepared Copilot rollouts amplify it across the organization at once.

How Rencore helps

Rencore Governance detects and helps prevent oversharing across SharePoint and OneDrive, and supports access reviews so entitlements match intent. Copilot readiness checks surface risky permissions before deployment, letting you clean up exposure first and roll out AI on a sound foundation. Policy monitoring keeps these controls active as the tenant changes, so improvements hold over time.

With the first scan reaching its first finding in under an hour, you can measure and reduce risk in days rather than months.

Where to go next

Start by detecting SharePoint oversharing, then prepare for a safe Copilot rollout. Read the oversharing concept to understand how permissions accumulate and how to bring them back under control.
