What happened
Rubrik announced (Aug 4-5, 2026, Black Hat) Agent Identity within Agent Cloud: an MCP Gateway that evaluates every tool call via behavioral analysis (SAGE), policy enforcement, and identity verification, issuing scoped short-lived tokens instead of standing access; integrates with Okta and Microsoft Entra ID.
Why it matters
Moves agent access control from broad standing permissions to per-action, moment-of-execution scoping — directly responding to Rubrik Zero Labs data showing only 23% of orgs have full visibility into their agents.
Applicability
Enterprises using Okta/Entra ID and running MCP-based agent tooling should evaluate as a least-privilege control layer.
