DigiCert confirms customer data breach following 16-month security lapse

Posted in Commentary with tags on November 9, 2026 by itnerd

Certificate authority DigiCert has disclosed a data breach involving an internal business system that was inadvertently exposed to the internet for more than 16 months following a February 2025 network migration.

The system, previously restricted to VPN access, allowed an unauthorized user to create an account without multifactor authentication and access archived customer information. DigiCert discovered unauthorized accounts on June 18, 2026, but initially dismissed them as harmless because they weren’t assigned to an application.

Although the vulnerability was addressed on July 2, the company didn’t confirm until October 19 that customer records had been accessed between June 27 and July 2. Exposed information included names, business contact details and, for some customers, passports, driver’s licenses and other identity documents. The number of affected customers remains undisclosed.

“A system that was behind a VPN for years and then sat on the open internet for 16 months tells you the migration checklist had no step that asked what else this change exposes. This is how most of these exposures start. No one re-verified reachability after the move, so the control everyone assumed was in place had quietly stopped existing. When unauthorized accounts are dismissed because they weren’t tied to an application, it means the team judged risk by what the account was assigned to rather than what it could reach. That is how an exposure turns into a confirmed records breach four months later.”

“Whenever I see articles like this, I get uncomfortable with the way information trickles out from the vendor, bit by bit by bit. Sometimes we don’t get a cohesive understanding of what happened until months later. This breach feels like that.

“First, there was a breach, but nothing sensitive was affected. Then, there was a breach, but we took care of it. Now we’re hearing that the exposure lasted more than 16 months.

“That pattern makes me question whether the slow release of information is intentional. I can’t say what the vendor’s intent is, but dribbling out details can bury a story. Something that would have been a very large story if disclosed all at once starts small and grows through updates that attract less attention.

“The story gets old. Writers and reporters end up covering what looks like the same incident again and again, even when the new information materially changes our understanding of it. That concerns me, because this is starting to look like a much larger breach than was initially reported..

“It’s either that, or they are very incompetent.”

Sharon Hagi, CSO, Finite State:

“Certificate authorities are the root of trust for the connected world. Billions of devices rely on them to prove who they are (identity), to authenticate each other (authentication and key exchanage), and to accept only genuine firmware updates (digital signatures). When a CA’s security fails, the damage can reach every system that trusts it.

“DigiCert says certificate issuance was not affected, and that matters. But this was not a sophisticated attack. It was a basic operational failure: a system was exposed for 16 months, accounts could be created without MFA, and confirming the breach took four months. The stolen identity documents are the same ones used to validate certificate holders, which gives attackers material for impersonation and social engineering. The fact that a certificate authority fell short in this case, is the material concern.

“CAs sit at the top of the trust hierarchy. They have to be held to a higher standard than anyone else in ecosystem, and they have to meet it.”

This is way too long to notify humans that you got pwned. And you have to question if people are paying attention. Especialy 16 months later.

DigiCert Acquires Valimail

Posted in Commentary with tags , on September 16, 2025 by itnerd

DigiCert, a leading global provider of digital trust, backed by Clearlake Capital Group, L.P. (together with its affiliates, “Clearlake”), Crosspoint Capital Partners L.P. (“Crosspoint”), and TA Associates Management L.P. (“TA”), today announced the acquisition of Valimail, a market leader in zero trust email authentication delivered as a service. With more than 92,000 clients worldwide, up 70% this past year, Valimail is recognized as a leader in protecting organizations from phishing, spoofing, and domain-based threats.

The acquisition advances DigiCert’s strategy of delivering end-to-end digital trust. Valimail adds leadership in zero trust email authentication to the DigiCert ONE platform that already brings together public CA, private PKI, certificate lifecycle management, and DNS to give customers a unified view of digital trust.

Valimail is a pioneer in Domain-based Message Authentication, Reporting, and Conformance (DMARC). Today, the company protects global brands, enterprises, and government agencies, and holds the industry’s most robust portfolio of DMARC-related patents. Valimail is also the only DMARC provider with FedRAMP authorization, underscoring its leadership in highly regulated environments.

DigiCert is also a leading global provider of Mark Certificates (MCs) and Verified Mark Certificates (VMCs), which enable organizations to display verified brand logos in customer inboxes. When combined with DMARC, VMCs power BIMI (Brand Indicators for Message Identification), allowing users to instantly recognize trusted emails. This not only helps prevent phishing but also reinforces brand identity with visual trust indicators such as the blue check mark alongside the sender’s name. By bringing together DMARC enforcement, VMCs, and DigiCert’s leadership in digital trust, organizations can deliver a safer and more trustworthy email experience for their customers.

Sidley Austin LLP served as legal advisor to DigiCert. Piper Sandler served as the exclusive financial advisor to Valimail while Fenwick & West LLP served as legal advisor.
