DigiCert

DigiCert is a wildly explosive, fiercely aggressive enterprise leviathan that mathematically defines the "High-Assurance Identity" market. While Let's Encrypt provides free encryption, DigiCert engineered a terrifyingly rigorous manual verification architecture (EV/OV). It is the absolute weapon of choice for Fortune 500 banks, governments, and healthcare providers who mathematically demand an ultra-premium cryptographic certificate backed by a $2 million warranty and exhaustive corporate identity validation.
