TL;DR: Manual renewals and fragmented ownership still let certificate expiry become service downtime, according to Fortanix. Certificate inventories and renewal paths need tighter automation and governance to keep trust from failing at the edge.
Editorial analysis by NHI Mgmt Group, based on content published by Fortanix: “7 Ways to Prevent the Next Outage with Proper Enterprise Key and Certificate Management”.
Key questions
Q: Why do expired certificates still cause outages in mature environments?
A: Expired certificates still cause outages because many environments rely on manual tracking, fragmented ownership, and renewal processes that do not match certificate growth.
Q: What do security teams get wrong about manual key rotation?
A: They treat rotation as a periodic task instead of a lifecycle control.
Q: What breaks when SSL certificate lifecycle management is not in place?
A: When certificate lifecycle management is weak, services can fail at expiry, trust chains can degrade silently and users may lose confidence in the site or application.
Practitioner guidance
- Implement continuous certificate discovery Build an authoritative inventory of certificates, keys and their owners across cloud, on-premises and application environments so expiry cannot hide in isolated systems.
- Automate renewal and rotation policies Remove manual renewal dates from operational dependence and enforce lifecycle actions through policy-driven workflows for both certificates and application keys.
- Tighten access to cryptographic operations Require least privilege, multi-factor authentication and quorum approval for key export, revocation and other high-impact operations.
Bottom line: Expired certificates and unmanaged keys create preventable outages because operational trust depends on lifecycle control, not just encryption.

Certificate lifecycle failure is an identity governance problem, not just an operations problem. Keys and certificates are machine trust credentials, so when their ownership, renewal and revocation are not governed, the organisation has created unmanaged non-human identity risk. The outage is only the visible symptom; the deeper issue is that no one can prove who owns each trust object, when it expires or how it is recovered. Practitioners should manage certificates with the same lifecycle discipline they apply to privileged access and service identities.
A question worth separating out:
Q: Should organisations prioritise automation before post-quantum cryptography planning?
A: Yes. Post-quantum planning matters, but without automated discovery and renewal, organisations cannot even see where their current keys and certificates live, let alone transition them safely. Inventory and automation create the control foundation that PQC migration depends on.
