Every organization has certificates it does not know about. These shadow certificates create blind spots that undermine security, compliance, and operational reliability. Gaining full visibility is the first step toward regaining control.
A shadow certificate is any digital certificate that exists in your environment but is not tracked, managed, or even known by the teams responsible for security and infrastructure. It is the certificate equivalent of shadow IT: something deployed outside the boundaries of official processes and oversight.
Shadow certificates are not inherently malicious. In most cases, they are created by well-intentioned developers, cloud engineers, or business units who need a certificate quickly and obtain one without going through the organization's formal request process. The problem is not intent; it is invisibility. When a certificate is invisible to your security and operations teams, it cannot be monitored for expiration, validated against policy, or rotated when a vulnerability is discovered.
Research consistently shows that organizations underestimate their certificate count by 40% to 70%. That gap, the difference between certificates you know about and certificates that actually exist, is your visibility gap. Closing it is one of the most impactful things a security team can do, because you cannot protect, renew, or govern what you cannot see.
A one-time scan is not enough. Deploy continuous discovery that automatically scans your networks, cloud environments, and endpoints on a regular schedule. New certificates should be detected within hours or days of issuance, not months later when they expire and cause an outage.
Define clear certificate policies that specify approved key algorithms, minimum key sizes, maximum validity periods, and required naming conventions. Then enforce these policies automatically. When a newly discovered certificate violates policy, the system should flag it and notify the responsible team.
Maintain a list of approved Certificate Authorities and make it easy for teams to request certificates from them. If obtaining a certificate from an approved CA is as fast and convenient as using an unapproved source, teams will naturally gravitate toward the approved path. Pair this with CT log monitoring to detect certificates issued by CAs outside your approved list.
Shadow certificates often appear because developers do not realize there is a proper process, or they find the existing process too slow. Address both sides: educate teams on the risks of unmanaged certificates, and streamline the official request process so it takes minutes, not days. Self-service portals with automated approval workflows are highly effective at reducing shadow certificate creation.
Continuous multi-source discovery — Evertrust CLM discovers certificates across your networks, cloud providers, endpoints, and CT logs. Scans run continuously so new certificates are detected within hours, not months.
Unified inventory — Every discovered certificate is automatically added to a centralized inventory with full metadata, ownership attribution, and expiration tracking. No more spreadsheets, no more surprises.
Policy violation alerts — Define your organizational policies once, and Evertrust automatically flags any certificate (new or existing) that violates them. Weak keys, unauthorized CAs, and non-compliant configurations are surfaced immediately.
Self-service with guardrails — Give developers a fast, approved path to obtain certificates through self-service portals backed by Evertrust PKI. Requests are fulfilled in seconds with built-in policy enforcement, removing the incentive to go outside official channels.
