Our Customers

Our customers—both large and small—come from every industry (business, ecommerce, education, financial, government). And our customers all have one thing in common: they take online security very seriously. Thousands of organizations—including Amazon.com, PayPal, Overstock.com, the Federal Bureau of Investigation, NASA, and the U.S. Department of Justice—all trust DigiCert certificates.


Enterprise and other large environments often need specialized SSL Certificate solutions. Luckily, DigiCert’s certificate offerings are designed to meet any need. Regardless of server OS, number of servers, or number of domains, one of our SSL Certificates is right for you. And, for customers in need of advanced management capabilities, we offer Managed PKI services. Managed PKI allows an organization with a large volume of SSL Certificates to take control of certificate management—including issuing new certificates and reissuing, replacing, and revoking existing certificates on demand.
