AI Summary

Izenpe S.A. reported a compliance failure involving the issuance of a certificate containing a duplicate attribute in the subject. This violation of the Baseline Requirements was detected after the certificate was issued on September 3, 2024, and was subsequently revoked the same day. The issue arose due to a change in their certificate management application that inadvertently affected EV certificates. Izenpe has since updated their linting tool and implemented new procedures to prevent similar incidents, including notifying the PKI team of any certificate revocations. All action items related to this incident have been completed, and Izenpe has requested closure of the case.
