One of DigiCert’s most valuable resources is the amount of trust they’ve harnessed over the years. Not only from their users and clients, but also from other contemporary companies and media conglomerates.

This being just one of many examples of DigiCert’s ubiquity, it will allow you to increase brand recognition and engagement across the board - simply by showing up in your users’ email inboxes without any fuss or trouble through the use of DMARC technology.

The History of DigiCert

The obtaining and management of SSL certificates wasn’t always as easy as it is today. We have certificate authorities such as DigiCert to thank for this streamlining of the process.

DigiCert was originally founded back in 2003. The business came about as the inevitable result of constant and consistent frustration with the then-available certificate providers and authorities. Founders of DigiCert wanted to distance themselves from these sloppy and unreliable companies and establish a new industry standard.

It quickly became clear that the process of purchasing and managing SSL certificates and PKI infrastructure needed to be made as simple as possible. This ended up being DigiCert’s targeted niche, and the sheer speed at which the company acquired consumer acclaim ended up being a sure sign of them being onto something.

An Evolution of Certificate Management and Online Security Solutions

By 2017, DigiCert had the unique opportunity to acquire the world's largest certificate authority, Symantec. Said acquisition also included the following brands; GeoTrust, Thawte, RapidSSL, and VeriSign. Another important acquisition was that of QuoVadis in 2018, which is Switzerland's largest and most trusted service provider.

DigiCert has been a major driving force in the industry when it comes to research and development, too. The company’s DigiCert Labs sub-division is dedicated specifically to producing innovative and out-of-the-box approaches to the rising security challenges of the 21st century.

The DigiCert Labs R&D collaborated with a variety of other enterprise labs - including that of Microsoft. They also offered numerous university grants to promising prospects. All of this to help improve data integrity, encryption, authentication, and safety, with DigiCert SSL certificates at the very pinnacle of their efforts.

DigiCert is also one of the only CAs that are actively researching post-quantum security with their own solutions to target potential vulnerabilities in encryption methods.

DigiCert SSL FAQ

DigiCert is a US-based digital security company that specializes in PKI (public key infrastructure) provision and validation for TLS/SSL certificates. They are a certificate authority (CA), and a trusted third party, ensuring their continued and successful operation in the software security niche.

DigiCert SSL Certificates (including, but not limited to DigiCert Secure Site) are trusted by every major operating system and web browser. This means that users of DigiCert-secured websites and digital content providers need not worry about their safety while perusing them.

On a similar note, DigiCert is also the CA of choice for many top-level tech companies in 2021. IBM, CloudFlare, and Wikipedia being just a few examples of many. High assurance rates are a given, at this level of business.

Yes. DigiCert uses PKI as a risk mitigation service first and foremost. PKI is an umbrella term for a wide variety of processes, technologies, and policies that allow users and businesses to sign and encrypt data without relying on outdated safety protocols.
