IT Leaders Overestimate TLS Certificate Visibility; 61% Experienced Certificate‑Related Outage in Past Year
What Happened — A recent Sectigo‑commissioned survey of 500 senior IT and security leaders across North America, EMEA and APAC revealed a stark gap between perceived readiness and actual automation of TLS certificate management. While 40 % of respondents said they felt “very prepared” for monthly TLS renewals, only 4 % have fully automated the process. In reality, 61 % reported a certificate‑related outage or incident in the last 12 months. The survey also showed that 73 % plan to increase automation as certificate lifespans shrink (CA/Browser Forum reduced the maximum validity to 200 days in March 2026, with further reductions slated for 2027 and 2029). Despite this, 33 % claim they are “extremely confident” they track all certificates—including rogue ones—while 48 % are “very confident.” The data suggests many organizations are unaware of certificates they do not control, creating a hidden attack surface and operational risk.
Why It Matters for Trust & Control Assurance — Incomplete inventory and manual renewal undermine the control objective of maintaining a reliable, auditable lifecycle for cryptographic assets, a key pillar of continuous compliance.
Who Is Affected — Enterprises that rely on public‑facing web services, SaaS platforms, cloud‑hosted APIs, and internal applications across all sectors (technology, finance, healthcare, retail, etc.).
Recommended Actions
- Deploy automated discovery tools to locate every TLS certificate—both issued and rogue.
- Implement a centralized certificate management platform that enforces scheduled renewals before expiry.
- Integrate certificate lifecycle logs into your SIEM and retain evidence for audit windows.
- Conduct a gap analysis against the “cryptographic asset inventory” control and remediate any missing or manually‑managed certificates.
Technical Notes
- CA/Browser Forum now caps public TLS certificates at 200 days (effective 15 Mar 2026), dropping to 100 days in 2027 and 47 days in 2029.
- Manual renewal cycles double the risk of missed expirations and service disruption.
- 61 % of surveyed firms experienced at least one outage linked to certificate expiry or misconfiguration in the past year.
