Keyfactor

Keyfactor provides PKI (Public Key Infrastructure) and machine identity management solutions for enterprises. The company helps organizations manage and secure cryptographic identities across devices, workloads, and digital transactions through certificate lifecycle automation and PKI-as-a-Service offerings.

The company originated in 2001 as a PKI consulting firm and has evolved into a provider of both cloud-based and on-premises PKI solutions. In 2021, Keyfactor merged with PrimeKey, the creators of the open-source EJBCA and SignServer platforms, expanding capabilities across critical infrastructure, cloud, and connected device ecosystems.

The company acquired CipherInsights and InfoSec Global in 2025 to strengthen post-quantum readiness and cryptographic visibility capabilities.

Keyfactor's platform addresses certificate management, code-signing certificate protection, SSH key management, and PKI deployment across various environments. The company serves over 1,500 enterprise customers across 70+ countries in industries where digital trust and authentication are critical requirements.

Their solutions support zero trust architectures, supply chain security, and crypto-agility for organizations managing identities at scale.

The company offers both SaaS-based certificate management and enterprise PKI infrastructure, with deployment options on Azure and AWS. Their technology stack includes automated certificate lifecycle management, cryptographic protection across identity lifecycles, and APIs for integration with existing systems.
