Entrust: Late revocation of underscore certificate

RESOLVED FIXED Entrust
AI Summary

Entrust failed to revoke nine SSL certificates containing underscores before the January 15, 2019 deadline set by the CA/Browser Forum. Although Entrust had encouraged subscribers to revoke such certificates, a flawed SQL query led to the oversight. The issue was detected after notification from Netcraft, prompting an investigation that revealed the missed revocations. Entrust has since updated their processes to prevent similar issues in the future, including changes to their query and requiring additional reviews for compliance activities.
