AI agent identity sprawl and access creep: what teams need to know

TL;DR: Weak identity governance turns excess access, manual access reviews, poor visibility, and AI agent sprawl into a larger attack surface, compliance gap, and operational burden as described by ConductorOne. The core issue is assumption failure: legacy IAM expects identities to stay stable, reviewable, and human-paced, but AI-era access does not.

NHIMG editorial — based on content published by ConductorOne: Risks of Weak Identity Governance in 2026

Questions worth separating out

Q: How should security teams reduce privilege creep across human and non-human identities?

A: Security teams should review entitlements by identity class, business purpose, and current usage, then remove access that no longer matches the role or workload.

Q: Why do manual user access reviews fail in modern identity programmes?

A: Manual user access reviews fail because the data is usually stale, incomplete, or too hard to interpret at scale.

Q: What breaks when AI agents are given permissions without lifecycle governance?

A: When AI agents are given permissions without lifecycle governance, ownership becomes unclear, revocation becomes slow, and auditability disappears.

Practitioner guidance

  • Map access creep by identity class Separate humans, service accounts, bots, and AI agents in entitlement reporting so privilege creep can be measured against the right baseline.
  • Automate UAR evidence collection and revocation Replace spreadsheet-driven reviews with current entitlement data, reviewer context, and enforced revocation workflows.
  • Build a complete inventory of high-risk identities Centralise visibility across SaaS, cloud, and automation layers so orphaned accounts, shadow IT, and over-privileged roles can be found before incidents do.

What's in the full article

ConductorOne's full blog covers the operational detail this post intentionally leaves for the source:

  • How the vendor structures access review automation for large entitlement sets across users and service accounts
  • The operational examples behind AI agent access sprawl and why legacy IGA breaks at scale
  • Practical guidance for reducing manual review effort while improving revocation accuracy
  • Implementation detail on building a stronger identity governance operating model

Weak identity governance is now an attack-surface multiplier, not a back-office control issue. When access, review, and visibility fail together, the environment becomes easier to traverse and harder to recover. This is the same structural problem whether the identity is human, machine, or agentic. Practitioner conclusion: identity governance has to be treated as a core security control, not an administrative layer.

A few things that frame the scale:

  • 85% of organisations lack full visibility into third-party vendors connected via OAuth apps, 38% have no or low visibility, and a further 47% have only partial visibility, according to The State of Non-Human Identity Security.
  • Only 1.5 out of 10 organisations are highly confident in their ability to secure NHIs, compared to nearly 1 in 4 for securing human identities, which shows how uneven governance maturity still is.

A question worth separating out:

Q: Who is accountable when excessive access leads to a breach or audit failure?

A: Accountability sits with the identity programme owner, the application owner, and the business approver who allowed access to persist beyond need. Compliance teams may see the failure first, but the control gap is usually upstream in ownership, review cadence, or revocation enforcement. Governance only works when accountability is tied to removal as well as approval.
