DigiCert
DigiCert operates the certificate infrastructure layer that secures roughly 90% of Fortune 500 enterprises and over 100,000 organizations globally. The company handles the fundamental cryptographic plumbing - public key infrastructure, TLS/SSL certificate issuance, IoT device authentication, and digital signing - that underpins encrypted connections, software authenticity, and identity verification at scale. The technical surface is broad. DigiCert's ONE platform consolidates PKI, DNS, and certificate lifecycle management into a single control plane. That matters because certificate sprawl is a real operational problem: expiration tracking, revocation management, and visibility across hybrid infrastructure create systemic risk. The platform layers AI-powered automation on top of these functions, plus extends into emerging threat surfaces like AI content authentication and agent protection. The company is also preparing for quantum-safe cryptography transitions, working on the problem of how certificate-dependent systems migrate to post-quantum algorithms. Beyond the ONE platform, DigiCert operates traditional high-assurance certificate authority services - the foundational role of issuing and managing TLS/SSL certificates, PKI hierarchies, IoT security credentials, and signing certificates. This positions the company at a chokepoint: if your organization needs proof of identity or encryption key binding, DigiCert's infrastructure often sits in the decision path. The breadth of customers - enterprises, cloud platforms, embedded device manufacturers, software publishers - means the company operates across multiple threat models and compliance regimes simultaneously.
