In a move that has sent ripples through the tech community, Google's Chrome Security Team has announced that it will no longer trust new server authentication certificates issued by Entrust, a leading certificate authority (CA). The decision, effective from Chrome 131, is a result of Entrust's pattern of compliance failures, unmet improvement commitments, and lack of transparency in incident response.

This development has significant implications for developers who maintain certificates, as it highlights the importance of contingency planning for scenarios where a CA may suddenly become distrusted. According to Arvid Vermote, CISO and head of security and compliance at GlobalSign, developers need to have backup plans in place, including automation, to ensure business continuity in the event of a CA being compromised.

The incident also underscores the need for automation in certificate management, with the trend shifting towards shorter certificate lifetimes and the adoption of automated certificate management environments (ACME) protocols. As the industry prepares for post-quantum cryptography, the importance of automation and contingency planning cannot be overstated.

In an era where trust is paramount, the Chrome team's decision serves as a warning to CAs and developers alike: transparency, accountability, and robust incident response are crucial to maintaining the integrity of the public key infrastructure (PKI) that underpins secure web communications.Cybersecurity
