DigiCert Tech Stack

PKI and digital certificate provider for enterprise security and identity

Computer and Network Security Lehi, Utah 1,001–5,000 employees Founded 2003 Privately Held

DigiCert operates a mature PKI and certificate infrastructure business serving Fortune 500 companies globally. The tech stack reveals a heavily containerized, cloud-native architecture (Kubernetes, Docker, Terraform, CloudFormation across AWS/Azure/GCP), paired with adoption of post-quantum cryptography and SPIFFE/SPIRE — indicating a shift toward zero-trust identity frameworks. Current hiring focuses on engineering and sales roles across 10 countries, while active pain points around renewal rates, account expansion, and fraud prevention suggest the core business is shifting from transactional certificate issuance toward relationship-driven, higher-touch account management.
