Private Enterprise PKI

Your own dedicated Certificate Authority, without the compliance program overhead

Private Compliance PKI is a cloud-hosted, WebTrust-audited CA hierarchy that belongs entirely to your organization. Your own Root CA and Issuing CA(s), HSM-backed keys, auditor-witnessed Key Ceremonies, and independently verified compliance controls, operated by SSL on the same infrastructure that underpins our public trust platform.

Dedicated CA infrastructure. Full control. Internal trust.

Private Enterprise PKI provides the same underlying platform as Private Compliance PKI, the same FIPS-hardened HSM infrastructure, the same unified REST API, the same enrollment protocols, and the same observability capabilities, without the WebTrust compliance program and its associated Key Ceremony audit requirements.

What you get:

Your own Root CA

A dedicated CA hierarchy, your Root and Issuing CAs are not shared with any other organization.

HSM-backed CA keys

CA keys generated and stored in FIPS 140-2 Level 3 certified Hardware Security Modules, never exportable in plaintext.

Full certificate lifecycle

Issuance, renewal, rekey, rollover, revocation via ACME, SCEP, EST, and REST API. Built for Kubernetes, MDM, DevOps pipelines.

Custom certificate profiles

Define profiles for your internal use cases, TLS, Client Auth, Code Signing, Device Identity.

What is different from Private Compliance PKI: No WebTrust independent audit coverage, no auditor-witnessed Key Ceremony, trust scope is internal only, certificates issued are not suitable for supply chain or partner ecosystem compliance claims. Lower cost.

Key benefits

Your own Root CA

Inherit SSL's WebTrust audit evidence for your PKI, without building or funding your own audit program.

FIPS 140-2 Level 3 HSMs

Partners, regulators, and customers can inspect your CA's audited governance, not just its certificates.

Full automation

ACME, SCEP, EST, REST API enrollment, built for DevSecOps, Kubernetes, MDM, and factory-floor issuance.

Unified REST API

The same SSL.com Web Services (SWS) REST API used for public-trust certificates: no separate SDK, no separate authentication, no parallel integration required for internal and external certificate workflows.

Custom certificate profiles

Hybrid post-quantum profiles (ML-KEM, ML-DSA, SLH-DSA) available at the Ecosystem/IoT tier.

Full observability

Full observability: certificate inventory dashboards, expiration forecasting, immutable audit logs with tamper-evident timestamping, and SIEM/SOAR integration for security operations visibility.

Lower cost than audited tier

All the dedicated infrastructure benefits of Private Compliance PKI without the WebTrust compliance program cost: the right choice when external audit evidence isn’t a requirement.

Who Private Enterprise PKI is for

Private Enterprise PKI is the right choice when:

  • Your use cases are internal only and you do not need to demonstrate your PKI governance to external partners, regulators, or customers
  • You need a dedicated CA hierarchy, not a shared platform, for policy, naming, or organizational reasons
  • You are running internal mTLS, VPN/Wi?Fi authentication, internal device identity, or developer/staging certificate infrastructure
  • Your organization wants full CA control over certificate profiles and policies without the compliance overhead
  • You want to progress to Private Compliance PKI in the future, Private Enterprise PKI uses the same platform and can be upgraded

If you need to demonstrate independently audited CA governance externally, for supply chain requirements, regulated industry compliance, or partner ecosystem trust, choose Private Compliance PKI instead.

Contact our PKI solution architects to design a Managed PKI deployment tailored to your environment. Our team will confirm your service tier fit, namespace requirements, and integration options for your enrollment systems (ACME, SCEP, EST, REST API).

Common use cases

Internal mTLS and service mesh

Medical devices, IIoT, automotive. Devices need an audited "birth certificate" for secure boot, firmware signing, and mTLS. The WebTrust audit proves the issuance process meets bank-grade security standards.

VPN/Wi-Fi authentication (EAP-TLS)

When government agencies or large enterprises require vendors to prove security infrastructure meets strict standards, the WebTrust seal on your dedicated PKI is the documented proof.

Internal device identity

The WebTrust-audited foundation pre-certifies the PKI component of your compliance audit. Signatures issued under an audited CA are legally defensible.

Kubernetes workload identity

Machine-to-machine service mesh, container identity, internal microservice mTLS. RBAC and dual-control enforced by the platform ensure no single person can issue a rogue certificate.

Developer and staging CAs

The Ecosystem tier supports hybrid PQC profiles combining RSA/ECC with ML-KEM, ML-DSA, and SLH-DSA. Use your dedicated environment to pilot quantum-safe certificates across internal workloads before broader rollout.

Frequently asked questions

Both give you a dedicated Root CA and Issuing CA(s) on the same FIPS-hardened platform. The difference is the WebTrust audit. Private Compliance PKI's Key Ceremony is witnessed by SSL's independent auditor, and your hierarchy is covered by the same audit program as our public trust operations, giving you "audit pass-through" for SOC2, HIPAA, supply chain, and partner compliance requirements. Private Enterprise PKI is the same infrastructure without the compliance program.

Managed PKI Certificates is a shared multi-tenant service, you don't own the Root CA. Private Enterprise PKI gives you a fully dedicated CA hierarchy with your own Root CA and custom certificate policies, not shared with any other tenant.

Yes, because both products are built on the same platform, upgrading to add WebTrust audit coverage is a process discussion, not an infrastructure migration.

Internal mTLS and service mesh, VPN/Wi-Fi authentication (EAP-TLS), internal device identity, developer and staging CAs, Kubernetes workload identity, and any scenario where you need a dedicated CA hierarchy for internal trust without external compliance requirements.
