TL;DR: RSAC 2026 conversations centred on reducing blast radius after initial compromise, with sessions spanning identity abuse, lateral movement, OT resilience, and AI-assisted policy design, according to ColorTokens. That framing matters because containment, not just prevention, is becoming the decisive control when modern environments are already breached.

By the numbers:
- 64% of valid secrets leaked in 2022 are still valid and exploitable today, proving that detection alone is not enough without automated revocation.
- 59% of compromised machines in a major 2025 supply chain attack were CI/CD runners rather than personal workstations.
Questions worth separating out
Q: What breaks when segmentation is not aligned with identity governance?
A: When segmentation is not aligned with identity governance, attackers can authenticate once and then move far beyond the original access decision.
Q: Why do service accounts and operator identities matter in containment design?
A: Service accounts and operator identities often hold the reach needed to cross from one system to another, so they define the real blast radius after compromise.
Q: How do security teams know whether blast-radius controls are actually working?
A: They know blast-radius controls are working when a test compromise cannot reach adjacent systems, critical workflows stay isolated, and enforcement matches the intended reachability map.
Practitioner guidance
- Map critical access paths to containment zones Identify the workloads, service accounts, and operator identities that can reach crown-jewel systems, then convert that map into explicit reachability rules.
- Review privileged identity scope with segmentation together Run access reviews and network policy reviews as one exercise for systems that matter most.
- Validate AI-generated policy before enforcement Require traffic simulation, exception review, and rollback criteria before any AI-assisted segmentation rule goes live.

Blast-radius containment is becoming the real test of security maturity. Prevention still matters, but this RSAC 2026 framing reflects a market reality: organisations are judged on how far an attacker can move after the first control fails. That makes microsegmentation and identity scope part of the same governance conversation. Practitioners should treat containment as a measurable control objective, not a narrative around resilience.
A question worth separating out:
Q: Who is accountable when containment fails after an internal breach?
A: Accountability sits with the teams that own the access model, the segmentation model, and the operational resilience outcome. In practice that means IAM, infrastructure security, and platform owners must share responsibility for post-compromise containment, because no single control plane can prove resilience on its own.
