TL;DR: Manual SSL certificate tracking no longer scales as organisations accumulate hundreds or thousands of certificates with different expiry dates, validation tasks, and monitoring needs, according to DigiCert. The governance problem is not the certificate itself, but the operational fragility created when lifecycle control depends on spreadsheets and fragmented oversight.
Editorial analysis by NHI Mgmt Group, based on content published by DigiCert: “Advantages to Using a Centralized Management Platform for SSL Certificates”.
Key questions
Q: What breaks when certificate ownership and expiry tracking are managed in spreadsheets?
A: Spreadsheet tracking breaks down when certificate volume grows and environments become distributed.
Q: Why do expired or misissued certificates create more than an availability problem?
A: Because a certificate is a trust assertion, not just a connectivity setting.
Q: How do security teams know if certificate lifecycle management is working?
A: Certificate lifecycle management is working when every certificate has a clear owner, renewal is automated or tightly managed, and expiry cannot occur without escalation.
Practitioner guidance
- Build a single certificate inventory Maintain one authoritative inventory of all SSL certificates, including issuer, expiry date, deployment location, and business owner, so teams can see the full estate without searching multiple spreadsheets.
- Automate expiry monitoring and alerts Set renewal alerts early enough to absorb approval delays, validation steps, and deployment windows, then route notices to the teams that actually own each certificate.
- Standardize deployment and inspection workflows Use a repeatable process for installation, monitoring, inspection, and remediation so certificate handling does not vary by team, environment, or issuing authority.
Bottom line: Manual certificate tracking becomes unreliable once the estate reaches hundreds or thousands of certificates and ownership is no longer obvious.

Certificate lifecycle sprawl is a governance problem before it is a tooling problem. The article shows that the real issue is the loss of reliable ownership and timing across a growing certificate estate. When administrators depend on spreadsheets, they lose the ability to govern expiry, validation, and remediation as a coherent lifecycle. Practitioners should treat certificate management as a trust inventory discipline, not a point-in-time admin task.
A few things that frame the scale:
- 48% of organisations cite cloud-based services as a driver for PKI deployment, according to the 2023 State of Machine Identity Management report.
A question worth separating out:
A: Organisations should treat certificate management as a governance problem, not just a tooling problem. Start by inventorying certificates across IT and OT, then centralise lifecycle tracking, renewal, and reporting so nothing is left unowned. Automation helps reduce outages and frees teams from manual renewal work, but the real objective is consistent control, auditable status, and reliable service delivery.
