DigiCert, 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 percent this past year, Valimail is recognised as a leader in protecting organisations 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.
Amit Sinha, DigiCert CEO, said: “Our strategy has always been to expand our platform’s capabilities with technologies that solve emerging threats for customers, and we believe that email authentication is the next logical step for DigiCert ONE. This strategy has guided our evolution from the world’s largest certificate authority company into a digital trust platform leader. Today, the rise of AI and the looming threat of quantum computing against current encryption have made it clear that the future of digital trust must be built on the belief that every digital interaction requires the right level of protection. Valimail is a leader in zero trust email authentication, with durable, foundational technology that is essential for securing email interactions at scale.”
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 authorisation, underscoring its leadership in highly regulated environments.
DigiCert is also a global provider of Mark Certificates (MCs) and Verified Mark Certificates (VMCs), which enable organisations to display verified brand logos in customer inboxes. When combined with DMARC, VMCs power BIMI (Brand Indicators for Message Identification), allowing users to instantly recognise 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, organisations can deliver a safer and more trustworthy email experience for their customers.
Alex Garcia-Tobar, Valimail CEO, said: “Our mission has always been to authenticate the world’s communications, starting with email. Teaming up with DigiCert helps accelerate our joint mission globally, aligning with the company’s broader trust ecosystem and ensuring that organisations are secure not only in their email, but across all their digital interactions. As a growth company, we’re excited to work closely with Amit and his leadership team to capture a larger share of the $4B+ market opportunity ahead of us.”
