Proactive SSL/TLS certificate lifecycle management. Prevent outages and protect your digital trust.
An expired SSL/TLS certificate is more than just an embarrassing browser warning—it represents a complete application outage, immediate customer friction, and broken data integrations. Manual spreadsheet tracking is a recipe for disaster.
Certificate Guardian automates the entire SSL/TLS certificate lifecycle, passively and actively scanning your public and private endpoints, executing hands-free renewals via ACME protocols, and warning you of security policy violations long before expiration day.
Complete lifecycle security and transparency monitoring for your SSL certificates.
Continuously crawls and profiles your public domains and internal subnets to discover, inventory, and audit all active certificates.
Seamlessly integrates with Let's Encrypt, ZeroSSL, and custom CAs to automatically renew and deploy certificates before they trigger warnings.
Scans public Certificate Transparency (CT) logs in real time to immediately detect and report unauthorized certificates issued for your domains.
Get smart notifications before certificates expire. Receive alerts via Slack, Teams, Email, or custom webhook integrations.
Join secure infrastructure teams who trust Certificate Guardian to protect their brand and uptime.
