Full CA hierarchy with X.509 Name Constraints, OCSP revocation, SPIFFE identity (X.509 + JWT-SVID), and Let's Encrypt ACME -- all managed from one platform.
See It In Action
Name Constraints enforced. Chain verified. ACME ready.
From root CA creation to automated renewal, every certificate is constrained, tracked, and audited.
Provision an offline ECDSA or RSA root CA with a hardware-backed key. The root signs intermediate CAs only -- it never issues leaf certificates directly.
Create scoped intermediate CAs with RFC 5280 Name Constraints -- permitted and excluded DNS names, IP ranges, and email domains enforced at the cryptographic level.
Workloads use the built-in ACME endpoint to request and renew certificates automatically. No manual CSRs, no expiry surprises, no toil for engineers.
From root of trust to certificate inventory, the entire lifecycle in one place.
Permitted and excluded DNS names, IP ranges, URIs, and email domains enforced as a CRITICAL extension -- intermediate CAs are cryptographically scoped to their environment.
Issue X.509-SVID and JWT-SVID identities for workloads. Every service gets a cryptographically verifiable identity -- no more service account passwords or shared API keys.
Built-in ACME server compatible with Certbot, cert-manager, and any RFC 8555 client. Workloads request and renew certificates automatically with no human involvement.
Real-time OCSP responder and periodic CRL distribution. Revoke a certificate and the change propagates immediately -- no waiting for cache expiry.
Name Constraints are not soft policy -- they are a CRITICAL X.509 extension. Any certificate authority in the chain that tries to issue a certificate outside its permitted scope will be rejected by every compliant TLS stack.
Every CA key is stored with envelope encryption (AES-256-GCM). The key encrypting key is backed by your chosen KMS -- AWS KMS, Azure Key Vault, HashiCorp Vault, or a PKCS#11 HSM. The private key never leaves hardware in hardware-backed configurations.
