TL;DR: Unpatched vulnerabilities remain a primary breach driver, with the article linking slow TPV to identity compromise, ransomware, and double extortion; Sophos, NinjaOne, and Verizon’s DBIR are cited to show how exploit windows translate into operational risk. Aligning patch speed with incident-response speed turns patching into an identity governance control, not just an IT hygiene task.
NHIMG editorial — based on content published by Unosecur: Why your TPV should match your MTTR: Reducing identity risk
By the numbers:
- Research collated by NinjaOne shows that unpatched vulnerabilities are responsible for roughly 60 percent of successful breaches.
- Only 5.7% of organisations have full visibility into their service accounts.
Questions worth separating out
Q: How should security teams align patching with incident response for identity systems?
A: Treat patching for identity-critical systems as a security response workflow, not a normal maintenance task.
Q: Why do delayed patches increase risk for IAM and NHI programmes?
A: Delayed patches extend the period in which attackers can abuse trusted systems to steal tokens, replay credentials, or escalate privileges.
Q: What breaks when identity platforms stay unpatched after disclosure?
A: What breaks is the assumption that identity control planes remain trustworthy until the next maintenance window.
Practitioner guidance
- Align patch priority to identity criticality Put domain controllers, SSO gateways, identity proxies, and credential vaults on the same emergency path used for active incidents.
- Link every patch wave to credential review After urgent remediation, inspect affected service accounts, API keys, and session material for leakage or reuse risk.
- Measure TPV beside MTTR on one dashboard Show patch latency and incident containment together for the same assets, with identical thresholds and escalation rules.

Patch latency is now an identity control problem, not a maintenance problem. Once attackers can use a disclosed flaw to reach credential material or privileged consoles, the delay between patch release and deployment becomes part of the attack surface. That means TPV belongs in the same governance conversation as access review and incident containment. The practical conclusion is that patch approval for identity-critical systems must be treated as a security control decision.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
- Only 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
A question worth separating out:
Q: Who is accountable when patch timing creates an identity breach window?
A: Accountability should sit jointly with security, infrastructure, and identity governance leads, because the risk spans vulnerability management and access control. Frameworks such as the NIST Cybersecurity Framework 2.0 support that shared responsibility model. The practical test is whether the organisation can prove its TPV target matches the urgency of its MTTR target.
