TL;DR: Google’s requirement that EV certificates issued after 1 January 2015 include Certificate Transparency proofs changes how browsers validate public trust, and certificates without the required logged evidence will no longer show Chrome’s green address bar, according to DigiCert. The governance lesson is that certificate lifecycle controls now have to account for public logging, not just issuance and renewal.
Editorial analysis by NHI Mgmt Group, based on content published by DigiCert: “Certificate Transparency Required for EV Certificates to Show Green Address Bar in Chrome”.
Key questions
Q: What breaks when a certificate is issued without Certificate Transparency support?
A: When a certificate is issued without Certificate Transparency support, browsers that enforce CT policy may not trust it.
Q: When should teams prioritise Certificate Transparency support over simple certificate renewal?
A: They should prioritise CT support whenever the certificate is publicly trusted and browser-visible trust signals matter.
Q: What are the signs that EV certificate governance is missing CT coverage?
A: The clearest sign is a mismatch between valid issuance and browser trust presentation, especially when certificates are renewed but the green address bar disappears.
Practitioner guidance
- Map EV issuance to CT proof requirements Check every EV certificate issuance path for the required number of CT proofs based on validity period and browser expectations.
- Inventory whether proof is embedded or stapled Record whether each public EV certificate carries CT proof in the certificate or via OCSP stapling so the owning control point is clear.
- Verify CA support before renewal Confirm that the certificate authority supports CT for publicly trusted EV certificates before the next renewal cycle begins.
Bottom line: Certificate Transparency changes EV certificate governance by making public logging part of the trust model, not just a browser feature.

Certificate transparency is now a governance requirement, not a browser quirk. The article shows that public trust indicators depend on logged proof, which means certificate lifecycle management extends beyond issuance, renewal, and expiry. Once browsers condition trust presentation on CT evidence, organisations must govern visibility as part of the certificate control plane. The practitioner takeaway is that certificate inventory now needs a proof layer, not just a validity layer.
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:
Q: How should teams manage public EV certificates versus internal certificates under CT rules?
A: Public EV certificates should be governed for CT logging and browser-visible trust, while internal or non-public certificates should not be treated as if they face the same presentation requirement. The governance model needs to separate public trust assets from internal-only certificates.
