RSAC 2026 DEBRIEF

Everyone at RSAC sold you agentic defense. We prove whether yours works.

We sat through 570 sessions so you don't have to. Here's the signal, plus a 15-minute readout to pressure-test your own stack against it.

01
THE SIGNAL UNDER THE NOISE

Three things actually mattered.

01

Defense went autonomous

Agents now act at machine speed. Almost no vendor could show theirs actually stops an intrusion.

02

Breakout time is seconds

Attackers reach lateral movement before a human reads the first alert. Real-time is the only honest test.

03

Your AI stack is the attack surface

LLMs, RAG, and agent identity are now yours to defend, and to prove, under NIST / EU / ISO scrutiny.

02
THE PROOF GAP

Claims aren't proof.

Every booth promised agentic defense. None could prove it holds, and with breakout time in seconds, that gap is exactly where breaches live.

What the floor sold
  • "Agentic" detection and response
  • AI coverage of the latest threats
  • Dashboards full of green checkmarks
  • Roadmaps that grade their own work
What SIEGE proves
  • Whether those agents stop a real intrusion
  • Live attack paths run against your controls
  • Evidence that survives a board or auditor
  • DARPA-defined rigor, not a vendor's word

DARPA CASTLE

SIEGE runs reasoning agents that emulate real adversaries, generating novel attack paths your tools have never seen, and hands you dated, board- and auditor-ready evidence of what held.

03
YOUR 15-MINUTE READOUT

Fifteen minutes. Three answers.

  • 01Your top attack-path exposure: where a real adversary would move first.
  • 02How agentic, machine-speed threats map to the controls you already own.
  • 03What board- and auditor-ready evidence of resilience actually looks like.

No slideware. No obligation. A working conversation about where a real adversary would go in your environment, and how you'd prove you'd catch them.
