Differentiation
Why Gatepost Over
Microsoft Native Tooling?
Microsoft Purview is a world-class data governance platform. It was not designed to govern AI agent retrieval. Gatepost closes the gaps Purview doesn't address.
Not a replacement for Purview
Gatepost is a governance layer that sits above your existing Microsoft stack. Purview handles data classification — Gatepost uses those classifications to govern what AI agents can retrieve. They are complementary, not competitive.
Deployed in your tenant, not ours
Unlike SaaS security intermediaries, Gatepost runs entirely within your Azure subscription. Your sensitive data never transits third-party infrastructure. This is the architecture enterprise security teams require.
Agent-aware, not just user-aware
Microsoft's native tooling enforces access at the user level. Gatepost enforces at the agent identity level — giving you distinct policy sets for Copilot, custom agents, and automated pipelines operating independently of human users.
Audit depth regulators expect
HIPAA, FCA, and ISO 27001 require demonstrable control at the point of AI retrieval. Gatepost's chunk-level audit trail with policy-version capture provides the evidence chain that file-level Purview logs cannot.

What about Microsoft Agent 365?
It's a fair question. Here's the honest answer.
Microsoft Agent 365 and SharePoint Advanced Management give you visibility into what agents access. They do not give you per-agent sensitivity ceilings, chunk-level audit trails, or policy version evidence pinned to each retrieval event. Those are architectural gaps, not roadmap items.
Gatepost is also additive to Microsoft tooling, not competitive with it. We consume Purview sensitivity labels. We write to your Log Analytics workspace. We deploy inside your tenant. When Microsoft extends its agent governance capabilities, Gatepost extends alongside them - your audit history remains intact.
The switching cost is your audit trail. Once your compliance reports reference Gatepost enforcement records, replacing the platform means losing the evidence chain retroactively. That is the moat - and it compounds with every month of production use.
"Not a replacement for Microsoft Purview — a governance layer Purview doesn't provide."
Gatepost integrates directly with your existing Purview sensitivity labels and Entra ID policies. You don't displace your current investment — you extend it to cover the AI retrieval layer.
