TL;DR: Fortune 500 cybersecurity posture is weak and identity compromise dominates breaches, with 84% of firms scoring D or worse and up to 71% of breaches tied to compromised credentials, according to Business Digital Index research cited by Clarity Security. The deeper issue is structural: access models built for periodic review cannot keep pace with human, NHI, and AI agent identities that change faster than governance cycles can see.
NHIMG editorial — based on content published by Clarity Security: Adaptive Trust and the evolution of identity security
By the numbers:
- Eighty-four percent of Fortune 500 companies score a D or worse for their cybersecurity efforts, according to Business Digital Index research analyzing companies across seven key security dimensions.
- With up to 71% of breaches now attributed to compromised credentials and identity-based attacks, the state of cybersecurity posture and the state of identity security are impossible to separate.
- Only 5.7% of organisations have full visibility into their service accounts.
Questions worth separating out
Q: How should security teams move from periodic access reviews to continuous identity governance?
A: Start by treating reviews as assurance, not detection.
Q: Why do non-human identities break conditional trust models?
A: Non-human identities break conditional trust because they outnumber human accounts, rarely appear in HR workflows, and often keep access long after the original purpose ends.
Q: What do organisations get wrong about just-in-time access for NHIs?
A: They often apply just-in-time thinking only to privileged human sessions and leave service accounts, API keys, and bots with standing access.
Practitioner guidance
- Inventory every identity class in scope Build a single inventory that includes human users, contractors, third parties, service accounts, API keys, bots, and AI agents.
- Collapse review findings into remediation workflows Route risk findings into direct remediation actions instead of ticket queues.
- Define where standing access must disappear Identify entitlements that should exist only for a task, then convert them to just-in-time access or removal by default.

Adaptive Trust is the clearest response to the failure of review-based identity governance. Campaign-driven governance assumes risk can be captured, assigned, and resolved on a human schedule. That assumption no longer holds when non-human identities, third-party credentials, and AI agents change state faster than the review cycle can observe. Practitioners should read this as a structural shift in how identity control must operate.
A few things that frame the scale:
- 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, according to the Ultimate Guide to NHIs.
- 71% of NHIs are not rotated within recommended time frames, increasing the risk of compromise over time.
A question worth separating out:
Q: How do you know if continuous remediation is actually working?
A: Look for reduced dwell time between risk detection and entitlement change, fewer identities outside lifecycle ownership, and fewer stale permissions surviving the review cycle. If risks remain open until the next campaign, the programme is still operating as a periodic review process rather than a continuous control.
