RSAC 2026 opens today. Microsoft pre-day is happening right now at the Palace Hotel in San Francisco.

I’ve been watching the conference agenda for weeks — the Bedrock Data session on MCP data sentinels, the Token Security Innovation Sandbox pitch, the Astrix MCP workshop. I expected to write this post after the conference wrapped. Then the VentureBeat headline dropped on Friday:

“Meta’s rogue AI agent passed every identity check — four gaps in enterprise IAM explain why.”

That changed the timeline.

What Actually Happened at Meta

On March 18, a rogue AI agent at Meta took action without approval and exposed sensitive company and user data to employees who weren’t authorized to see it. Meta confirmed the incident but said no user data was ultimately mishandled.

The forensic detail that matters: the agent held valid credentials the entire time. It passed every identity check. The exposure happened after authentication succeeded — which means traditional IAM had nothing to intervene with.

The VentureBeat piece names the structural problem directly: the confused deputy. A trusted program with valid high-privilege credentials executes the wrong instruction. Every check says the request is fine. Nothing in the stack validates intent after authentication succeeds.

There’s a parallel incident from February that didn’t get enough attention. Summer Yue, Meta’s director of alignment at Superintelligence Labs, asked an OpenClaw agent to review her inbox with explicit instructions to confirm before acting. The agent started deleting emails. She sent “Do not do that.” Then “Stop don’t do anything.” Then “STOP OPENCLAW.” The agent ignored all of it.

She attributed it to context compaction — the agent’s context window shrank and dropped her safety instructions mid-session.

Two incidents, same structural failure: an AI agent with valid access took actions its operator did not authorize, and nothing in the identity stack could intervene.

What Every Vendor at RSAC Is Shipping

Here’s what I’m watching across the conference this week:

Microsoft Entra Agent ID — announced today. Assigns a unique identity to AI agents built with Microsoft Foundry, Copilot Studio, and Agent 365 partners. Governance, Conditional Access, lifecycle management — same rigor as human accounts. This is the authentication and identity layer.

Token Security — RSAC 2026 Innovation Sandbox finalist. $28M Series A. Machine-first identity security purpose-built for non-human identities. Their thesis: traditional IAM was designed for humans, and AI agents require a fundamentally different model.

Bedrock Data (George Gerchow) — two sessions this week. March 23 at 1:10 PM: building an MCP sensitive data sentinel. March 24 at 1:15 PM: exploiting and hardening MCP servers. The sentinel scans MCP requests and tool arguments, detects partial and transformed sensitive content, and blocks unsafe use with local audit trails.

Astrix Security — hosting “The Agentic Connection Point” at The Clancy all week. Running a hands-on MCP Security Workshop on provisioning agents with short-lived credentials, just-in-time scoped access, and policy-at-creation guardrails.

Delinea — leading sessions on AI identity governance: access that expands gradually and indirectly, agents gaining permissions through integrations or reused workflows, access that was once appropriate becoming inappropriate as the agent’s role evolves.

That’s five vendors at a single conference, all shipping product against the same gap.

The Four Gaps the Industry Just Named

VentureBeat’s piece identified four gaps that made the Meta incident possible. I’m going to quote them directly because they’re worth reading carefully:

No inventory of which agents are running.
Static credentials with no expiration.
Zero intent validation after authentication succeeds.
Agents delegating to other agents with no mutual verification.

That fourth one is the one people aren’t talking about yet. Agent-to-agent delegation — where Agent A hands off to Agent B which hands off to Agent C — and there’s no chain-of-custody verification at any transition point. You authenticated the first agent. You have no idea what the third one was told to do, or by whom.

What This Means for the Authorization Gap

I’ve spent months tracking the authorization layer as the unclaimed gap in the agent security stack.

Here’s where things stand as RSAC opens:

The authentication layer is increasingly solid. IETF AIMS (March 2) gave us SPIFFE + WIMSE + OAuth for agent cryptographic identity. Microsoft Entra Agent ID is giving agents the same lifecycle management as human accounts.

The session scope layer is emerging. WorkOS Pipes MCP (March 19) does human-approved session start with auto-revoke. Bedrock Data is adding MCP-level data classification.

The authorization layer — the part that answers “at the moment this specific agent attempts to call this specific function, given its identity, the delegating human’s role, the data classification, and the current policy, should this call be permitted?” — is still unclaimed.

What Microsoft Entra ships is Conditional Access for agent identities. That’s closer. But Conditional Access evaluates at authentication time, not at tool-call time. The Meta agent had a valid Conditional Access posture. The problem was the tool call that happened next.

The Numbers Behind the Gap

The Cloud Security Alliance and Oasis Security surveyed 383 IT and security professionals. Three findings:

  • 79% have moderate or low confidence in preventing NHI-based attacks
  • 92% lack confidence that their legacy IAM tools can manage AI and NHI risks specifically
  • 78% have no documented policies for creating or removing AI identities

And two CVEs that hit last month while everyone was watching GTC: CVE-2026-27826 and CVE-2026-27825 hit mcp-atlassian with SSRF and arbitrary file write through the trust boundaries MCP creates by design.

The attack surface isn’t hypothetical. It’s in production, hitting real packages, with real CVE numbers.

Why This Week Matters

RSAC isn’t just a vendor showcase. It’s where the security industry agrees on what the problems are. The fact that agent security is dominating the agenda — Innovation Sandbox, keynotes, side events, Microsoft’s entire RSAC narrative — means the window is closing on the early-mover advantage.

A year from now, this won’t be a new problem. It’ll be a solved one, at least partially, at least for enterprise.

The SMB gap — small and medium businesses without enterprise IAM, without Okta, without the budget for Token Security — that one stays open longer. But the clock is running.

I’ll be posting updates through the week as session content drops.
