The record

Purpose: Certynx helps organizations discover, govern, automate, and remediate machine identities.
Automated renewal: It issues, validates, and deploys certificates automatically before expiration.
Policy and audit: It enforces key strength, validity limits, and approved certificate authorities at issuance, recording actions in a tamper-evident, hash-chained audit log.
CA orchestration: Its API works across public and private CAs, including Let’s Encrypt, DigiCert, EJBCA, Vault, and AD CS.
Post-quantum readiness: It inventories cryptographic algorithms, identifies migration requirements, and supports orchestration toward post-quantum cryptography.
CT monitoring: It monitors Certificate Transparency logs for unexpected certificates issued for a customer’s namespaces.
Integrations: The site lists AWS, Azure, Google Cloud, Kubernetes, HashiCorp, DigiCert, Sectigo, Let’s Encrypt, Keyfactor, Entrust, Cloudflare, F5 BIG-IP, ServiceNow, PagerDuty, Slack, and PKCS#11.
Deployment: Deployment options are fully managed cloud, private cloud in a VPC or data center, and air-gapped installation.
Key handling: For HSM-backed issuance, keys are generated and used inside the HSM, and Certynx says it sees only a handle, never the key.
Air-gapped installation: The air-gapped deployment runs without cloud reachback and offers signed images with an SBOM and offline-reproducible installation.
Intended users: The site describes the product for security and PKI, platform and DevOps, and compliance and risk teams.
Setup: Certynx says connecting a read-only source can build a live inventory of certificates, expirations, weak algorithms, and blind spots within about an hour.
Support: The contact page says the team typically responds directly within one business day and provides [email protected] for vulnerability reports.
