DigiCert has confirmed a security breach involving an internal business system that stored archived customer information and identity documents. The incident resulted in unauthorized access to customer records containing names, business email addresses, phone numbers, and business addresses. A limited number of customer accounts also included sensitive documents such as passports, driving licenses, and utility bills. The unauthorized access was confirmed on October 19, 2026, although the actual data exposure occurred between June 27 and July 2, 2026. DigiCert stated that its certificate services and issued certificates were not affected. The incident originated from an infrastructure migration conducted on February 4, 2025, which moved an internal system from a VPN-protected network to an externally accessible environment. This change unintentionally exposed a self-registration feature that allowed unauthorized accounts to access archived customer records with read-only permissions. The accounts bypassed the company's employee MFA requirements due to weaknesses in the authorization process. Although DigiCert initially identified suspicious account registrations in June 2026, the issue was not immediately recognized as a data exposure incident. Investigators later confirmed that unauthorized users had accessed sensitive customer information. Organizations using DigiCert services should review their notifications and determine whether their archived customer information was involved. Businesses should monitor suspicious communications and phishing attempts that may use exposed contact or identity details. Administrators should enforce MFA, review account permissions, and ensure internal applications are not unnecessarily accessible from public networks. Regular security assessments, access monitoring, and proper authorization checks should also be implemented to prevent similar incidents. DigiCert customers do not need to replace active certificates as a result of this breach.
