The Agent Oversharing Problem: Why We Need to Get Governance Right, Now
We've all been there. You roll out Microsoft's AI agents across Teams and SharePoint, your teams start collaborating faster, and suddenly your CIO and Chief Security Officer are in your office with a problem you didn't see coming.
It's not just Microsoft's fault, though Gartner's latest research AI Agents Guide: Microsoft (2025), shows that governance controls are fragmented across five different admin centers, and only 14% of IT leaders actually feel confident they have the right guardrails in place. The real issue? Your organization's most powerful collaboration tools are now moving data faster than your compliance framework can track it.
That's what we call the oversharing problem.
What Happens When Autonomy Outpaces Oversight
Copilot and our AI agents can read, reason, and summarize across our entire corporate dataset. That's incredible for productivity. But it's terrifying if we're not careful.
When permissions get messy, these tools can surface confidential information to people who were never supposed to see it. Or worse, to other AI agents making decisions downstream. Five years ago, oversharing meant someone forwarded a confidential file to the wrong person. Today, it means an autonomous agent is reasoning over unclassified data and sharing insights across your organization without anyone knowing where that information came from. Soon enough these agents will be used to not just share internally but beyond organizational boundaries in which the problem only compounds.
For companies in regulated industries, this isn't just a problem. It's a risk that could bring their organizations to a halt.
Why Our Current Tools Aren't Enough
Microsoft has made serious strides in governance. Purview, Entra, and Copilot Studio bring capabilities like classification, labeling, and even prompt governance for AI interactions. These are powerful tools — but they don’t solve the whole problem.
Here’s the catch: governance needs to consider security, collaboration (modern work), identity, and AI. Companies need to include all of these stakeholders to enable business to work in an efficient and secure manner.
The Answer: Governance That Actually Works
The solution isn't to slow down our digital transformation. It’s to embed governance into the collaboration layer itself.
That’s where eSHARE comes in. It doesn’t replace Microsoft’s governance; it amplifies it. By extending Purview’s classification and DLP policies into real-world sharing workflows, eSHARE makes external collaboration secure without slowing innovation.
No guest account sprawl. No shadow systems. Just governed collaboration inside Microsoft 365, continuously audited, policy-driven, and ready for scale.
Think about what that means operationally:
Data never leaves Microsoft 365. No exports, no workarounds, no shadow storage systems. Identities stay managed and auditable. External collaboration happens without the mess of guest account sprawl. Governance is continuous where every interaction either at the point of sharing or access is automatically logged and protected by proven data protection as well as compliance policies.
When Copilot expands what our teams can do, this approach gives us the confidence to let it. Compliance and innovation aren't fighting each other anymore.
The Real Competitive Advantage
The enterprise landscape is shifting fast. We're not just adopting AI agents: we're building organizations where humans and AI collaborate seamlessly, at scale, across teams and sometimes across companies.
But here's what separates the winners from the rest: the companies that scale collaboration and governance together. Gartner calls this the next evolution of enterprise productivity, and they're right. But productivity without governance isn't ambition — it's recklessness.
The future of enterprise collaboration isn't about moving files faster or managing guest access better. It's about building a trusted collaboration fabric that's intelligent by design and compliant by default. It's about choosing governance that empowers, not restricts.
That's the direction we need to move, and it's the only way teams unlock what these AI tools can really do.
