TL;DR: Unosecur says the ECB has ordered significant euro-area banks to submit by 31 October 2026 an action plan for AI-driven cyber risk, with priorities including exposed assets, faster patching, stronger monitoring, and zero-trust identity controls across users, APIs, and service accounts. The message is that perimeter assumptions are now obsolete and identity governance has become a supervisory requirement, not an internal preference.
Editorial analysis by NHI Mgmt Group, based on content published by Unosecur: “The ECB Just Mandated What Identity Security Teams Have Been Asking For. Here Is What Banks Must Do By October 2026”.
Key questions
Q: What breaks when organisations rely on periodic access reviews for AI systems?
A: Periodic access reviews break when the identity scope changes between review cycles.
Q: Why do service accounts and APIs increase risk in the ECB's zero-trust model?
A: Because the model assumes attackers can move through identities after initial access, not just through networks.
Q: What are the signs that identity controls are not keeping pace with AI-driven threats?
A: Common warning signs include stale credentials, excessive privileges, delayed access reviews, weak visibility into who has access, and security teams relying on manual approvals for changes that should be automated.
Practitioner guidance
- Map every identity and asset continuously Build and maintain an always-current inventory of human identities, non-human identities, cloud assets, VPN paths, and third-party connections so exposed attack surfaces are visible before they are exploited.
- Shift identity controls to runtime enforcement Treat access review as supporting evidence, not the primary control, and enforce least privilege and verification at the moment access is used.
- Expand monitoring to identity behaviour Correlate access logs, anomalous service-account activity, and external exposure signals so compromise indicators are detected while exploitation windows are still open.
Bottom line: The ECB letter treats identity controls as part of bank resilience because AI is compressing the gap between vulnerability discovery and exploitation.

Identity governance is now a supervisory resilience control, not an IAM preference. The ECB letter makes clear that banks are being judged on whether identity controls can absorb faster exploitation cycles, not just whether they exist on paper. That shifts the centre of gravity from access administration to continuous operational control. For financial institutions, the practitioner implication is that identity programmes now need to be defended as resilience infrastructure.
A question worth separating out:
Q: How should banks align DORA readiness with identity governance under the ECB letter?
A: Banks should treat DORA implementation as an operational resilience programme that includes identity scope, runtime logging, least privilege, and supplier access. The regulatory expectation is not a document set alone. It is evidence that identity can be governed continuously across internal and external boundaries.
