What Certynx is

Certynx manages machine identities for organizations, with certificate discovery, policy enforcement, automated renewal and remediation. It searches networks, cloud environments, Kubernetes and Certificate Transparency logs to build a live certificate inventory. Teams can use that inventory to see expirations, weak algorithms and blind spots; connecting a read-only source can produce it in about an hour. Certynx can issue, validate and deploy certificates before they expire, enforcing rules for key strength, validity periods and approved certificate authorities. Its actions go into a tamper-evident audit log, and its API works with public and private CAs, including Let’s Encrypt, DigiCert, EJBCA, Vault and AD CS. It also monitors Certificate Transparency logs for unexpected certificates associated with customer namespaces and inventories algorithms to identify post-quantum migration requirements. Deployment choices include managed cloud, private cloud in a VPC or data center, and an air-gapped installation. For HSM-backed issuance, keys stay inside the HSM; Certynx receives a handle rather than the key. The air-gapped version operates without cloud reachback and offers signed images with an SBOM and offline-reproducible installation. The product is aimed at security and PKI, platform and DevOps, and compliance and risk teams.
