PKI Spotlight

PKI Spotlight is a real-time monitoring and alerting platform designed to give organizations clear, actionable visibility into their Public Key Infrastructure (PKI). Developed by PKI Solutions, it helps IT and security teams stay ahead of issues by continuously watching over critical components like Certificate Authorities (CAs), Hardware Security Modules (HSMs), and certificate templates. One of the standout features is its “Is-Alive” capability, which checks the health and responsiveness of key PKI elements such as CAs and OCSP responders. This ensures that services are operational and can alert teams to potential problems before they escalate. PKI Spotlight also offers a comprehensive inventory of CA, NDES certificates, Certificate Revocation Lists (CRLs), and OSCP responders tracking their validity and providing proactive renewal alerts. This helps prevent unexpected expirations that could disrupt services. For organizations using multiple HSM vendors, PKI Spotlight provides unified monitoring across different platforms, including Entrust (nCipher) and Thales (Luna). This consolidation simplifies management and enhances visibility into the performance and health of these critical security devices. Security posture management is another key aspect. PKI Spotlight detects over 100 best practices, misconfigurations, and vulnerabilities, such as those identified in the SpecterOps Certified Pre-Owned report, and alerts teams to potential threats like the PetitPotam attack. This proactive approach helps organizations maintain a strong security stance. In summary, PKI Spotlight serves as a centralized tool that simplifies PKI management, enhances security, and ensures operational continuity by providing real-time insights and alerts across the entire PKI environment.
