TL;DR: Certificate outages are usually a symptom of deeper PKI governance problems, not isolated IT failures, because manual operations, fragmented ownership, and shrinking certificate lifetimes create persistent identity risk according to Palo Alto Networks. The real issue is that certificate management has become an NHI governance problem, not just an infrastructure task.
Editorial analysis by NHI Mgmt Group, based on content published by Palo Alto Networks: “The Hidden Cost of PKI: Why Certificate Failures Aren’t Just an IT Problem”.
Key questions
Q: What breaks when certificate renewal is still handled through manual workflows?
A: Manual renewal workflows break first at scale because they cannot keep pace with recurring expiry windows and cross team dependencies.
Q: Why do certificate outages create identity governance risk instead of just downtime?
A: Certificate outages create identity governance risk because the certificate is what allows systems to trust each other.
Q: What are the signs that certificate governance is failing in critical infrastructure?
A: Common warning signs include unclear ownership, expired certificates, mixed use of approved and unapproved issuers, and last-minute manual renewals.
Practitioner guidance
- Establish certificate ownership mapping Assign a named business or technical owner to every internal certificate, private CA, and renewal path so no asset sits outside accountable governance.
- Automate renewal before shortening lifecycles Use automated renewal workflows for certificates with tight expiry windows, especially where multiple platforms or teams depend on the same trust chain.
- Inventory certificate dependencies continuously Track which applications, workloads, devices, and services rely on each certificate so you can see the blast radius before expiry or revocation.
Bottom line: Certificate failures are best understood as machine identity governance failures because certificates function as credentials, not background plumbing.

Certificate lifecycle management is now a machine identity control, not an infrastructure convenience. Certificates authenticate machines, services, and internal applications, so their ownership and renewal are governance questions, not just operations tasks. When teams centralise only the tooling but not the accountability, the control fails at the point of trust. The implication is that certificate governance should sit alongside other NHI lifecycle controls, not outside them.
A few things that frame the scale:
- Organisations maintain an average of 6 distinct secrets manager instances, creating fragmentation that undermines centralised control, according to the State of Secrets in AppSec.
- Enterprises manage far more machine secrets than human ones: 20 times as many according to Enterprise Strategy Group, and 45 times according to GitGuardian.
A question worth separating out:
Q: How should security teams govern certificate lifecycle risk in hybrid environments?
A: Security teams should treat certificate lifecycle as a governed identity process, not an ad hoc infrastructure task. That means every certificate must have an owner, an expiry path, a renewal workflow, and a retirement record. The strongest programmes automate issuance and renewal while keeping policy, auditability, and exception handling under central control.
