Why PKI Health Is Critical

Health is the human metric that summarizes availability, integrity and configuration correctness so admins can quickly understand whether an entity is fit for purpose and why it is or isn’t. PKI Insights uses the same concept and maps technical health at a scale of A+ to F so PKI admins, security teams and auditors can all speak the same language: healthy, degraded (and why), or critical – then act immediately. When any PKI component (CA, HSM, TLS endpoint) is unhealthy, the result is outages, failed audits, weakened trust, and increased attack surface.

Key outcomes of poor PKI health

  • Service outages from expired or mis-chained certificates

  • Silent security gaps (weak keys, improper extensions) that enable abuse

  • Audit failures and compliance risk (protocols, cipher suites, crypto standards)

  • Hidden ADCS/HSM faults that escalate into larger incidents

How PKI Insights Calculates Health (ADCS, HSM, SSL/TLS)

PKI Insights continuously computes a health score for every monitored object and explains the cause when health drops. Health is derived from many discrete checks; each check contributes to the score and generates an actionable finding.

ADCS / Certificate Authorities – what’s checked

  • 250+ checks made against the issued certificate

  • CA availability and failed call rates (up/down, latency, error counts)

  • Issuance anomalies and issuance trends (spikes, unusual principals)

  • Weak keys or deprecated signing algorithms (e.g., non-approved sizes or hashes)

  • Certificate structural and profile checks against RFC 5280 (chain, validity, extensions)

  • Detection of ADCS abuse patterns and exposure (SpecterOps ESC categories, PetitPotam-style coercion indicators)

  • Certificate extension correctness per Microsoft recommendations (template EKUs, enrollment ACLs)

  • Template & ACL drift, misconfigurations and unauthorized template changes

HSMs – what’s checked

  • HSM availability and CA connectivity (up/down, response time)

  • Device-level telemetry: slot and device status, uptime, firmware version and changes

  • Hardware health: battery status (where applicable), CPU, memory, and performance metrics

  • Key usage, slot errors, and HSM-reported faults or warnings

  • Certificate expiry of keys/certificates stored or referenced by HSMs

  • Human-readable, auditable logs for every check and event produced by the HSM monitor

Vendor depth: PKI Insights collects 50+ HSM data points for Thales and similar deep telemetry for Entrust and Utimaco, so you get vendor-specific insight, not just generic pings.

SSL/TLS Endpoints – what’s checked

  • Certificate expiry, chain correctness and RFC 5280 structural validation

  • Public vs internal endpoint parity and coverage (internal services often missed)

  • Weak keys or legacy signing algorithms in use on endpoints

  • TLS protocol and cipher analysis (deprecated vs compliant configurations)

  • Connectivity and handshake failures (latency, broken chains, renegotiation issues)

  • PQC/hybrid TLS indicators where applicable (support or lack thereof)

Fix Faster: Built-in Guidance & Remediation Wiki

Health without guidance is only a warning. PKI Insights pairs each finding with concise remediation steps drawn from a built-in wiki so admins can fix issues faster and with confidence.

Remediation features

  • Contextual playbooks (what changed, why it matters, step-by-step resolution)

  • One-click links to relevant CA/HSM/endpoint configuration views and logs

  • Prioritized recommendations based on severity and potential business impact

  • Auditable change history once remediation steps are executed
