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.
