TL;DR: Identity-based attacks are now the dominant enterprise entry path, and the article argues that legacy IAM, IdPs, and quarterly access reviews were built for a pre-cloud world that no longer exists, according to Newcore. The architecture problem is no longer hypothetical: identity platforms must govern humans, workloads, and agents together, or they become the weakest part of the stack.

Editorial analysis by NHI Mgmt Group, based on content published by Newcore: “The New Identity Manifesto”.

Key questions

Q: What breaks when an identity platform is still built for pre-cloud access patterns?

A: Periodic review, static trust boundaries and human-paced administration all break down when the platform has to govern services, workflows and agents as well as people.

Q: Why do identity platforms create more risk when they become the main authentication layer?

A: Because compromise of the control plane now has enterprise-wide consequences.

Q: How can security teams measure whether agentic AI is improving identity governance rather than just speeding up requests?

A: Teams should measure operational outcomes, not just response time.

Practitioner guidance

  • Map the identity control plane Document which authentication, federation and token services sit at the center of enterprise access so you can assess where a single compromise would have the broadest blast radius.
  • Separate actor classes in governance design Model humans, workloads and autonomous agents in one identity graph, but keep lifecycle, policy and attribution rules explicit for each actor type.
  • Review trust primitives for single points of failure Identify shared secrets, replayable tokens and signing paths that could turn one stolen assertion into enterprise-wide access.

Bottom line: Legacy IAM is now failing as an architecture model because identity-based attacks exploit the same systems that enterprises rely on for authentication and trust.

Identity platforms have become enterprise risk centers, not neutral plumbing. When the systems that authenticate the workforce are also the systems most likely to be targeted, the control plane itself becomes part of the threat surface. That shifts identity from a support function to a core security dependency, and practitioners should treat it that way in architecture reviews.

A question worth separating out:

Q: Should organisations migrate before they fully exhaust their legacy identity stack?

A: Yes. When a legacy identity stack depends on escalating customisation, manual review effort and specialist knowledge that is already scarce, waiting only deepens the debt. Migration should be timed to restore governance capacity before access complexity becomes unmanageable. The practical issue is control continuity, not platform sentiment.
