PKI Security & Resilience Assessment & Remediation

Assess PKI architecture, certificate templates, revocation services and recovery readiness, with a remediation roadmap.

Public Key Infrastructure frequently becomes a hidden dependency for authentication, device trust, encryption and application security.

Many enterprise PKI environments remain operational for years while certificate templates, revocation infrastructure, administrative permissions and recovery procedures gradually diverge from the original design.

This assessment examines PKI as both a security control and a critical trust infrastructure.

What we assess

CA architecture

  • Root CA
  • Issuing CAs
  • Online and offline roles
  • CA hierarchy
  • Role separation
  • Enterprise CA dependencies
  • Legacy CA infrastructure

CA security

  • Administrative permissions
  • CA operator roles
  • Key protection
  • HSM usage where applicable
  • Audit configuration
  • Operating system security
  • Service-account dependencies

Certificate templates

  • Template permissions
  • Enrollment rights
  • Autoenrollment
  • Subject-name configuration
  • EKUs
  • Authentication-capable templates
  • Legacy templates
  • Template lifecycle

Revocation and publication

  • CRL
  • Delta CRL
  • AIA
  • OCSP
  • Publication locations
  • Availability
  • Expiration margins
  • Client dependencies

Certificate lifecycle

  • Enrollment
  • Renewal
  • Revocation
  • Expiration
  • Certificate ownership
  • Application dependencies

Identity dependencies

  • Domain controllers
  • Certificate authentication
  • Windows Hello for Business
  • Network authentication
  • Device authentication
  • Application authentication

Resilience and recovery

  • CA backup
  • Private-key backup
  • CA database recovery
  • Revocation availability
  • Disaster recovery
  • CA migration
  • Recovery testing

What you receive

  • PKI architecture assessment
  • Certificate-template risk review
  • Revocation-infrastructure assessment
  • Administrative-access findings
  • Dependency map
  • Resilience findings
  • Remediation roadmap
  • Modernization design
  • Post-remediation validation

Example public finding

This is an illustrative example, not a finding from a customer assessment.

PKI-021 — Certificate revocation availability depends on a single publication path

Observation

Certificates reference revocation information through an HTTP publication path that depends on a single server or service instance.

Why it matters

Certificate validation may depend on the continuing availability of revocation information.

A failure of the publication service can therefore affect authentication or application behavior beyond the certificate authority itself.

Recommended direction

Separate certificate issuance from revocation publication, provide an appropriate resilient publication architecture, validate client behavior during endpoint failure and ensure CRL publication remains operational throughout CA maintenance or migration.
