The growing complexity of certificate management
Managing digital certificates is more challenging than ever.
Shorter lifespans, rapid growth, new regulations, and emerging cryptography standards are reshaping the landscape.
To stay secure and resilient, organizations must keep certificates visible, compliant, and ready for what’s next.

Red Sift Certificates provides real-time discovery of new certificates and seamless monitoring for expiration and revocation.
Get full visibility into your public PKI by combining real-time monitoring of the Certificate Transparency ecosystem with discovery across hostnames and services.
Monitor deployments to catch misconfigurations, expired or undeployed certificates, and gaps left by incomplete automation before they lead to outages.
Correlate certificate data with DNS, CT logs, and more to quickly surface risks during industry-wide incidents like the Entrust Distrust event.
Get alerted to rogue certificate activity like unauthorized issuances within minutes, and take action before it leads to compromise.
Continuously monitor deployed, unused, and newly issued certificates to surface misconfigurations, expired certificates, and suspicious issuances early before they lead to outages or breaches.
View detailed configuration data like key strength, algorithm type, endpoint status, and deployment location so you can spot weak deployments, maintain crypto hygiene, and prepare for post-quantum standards.
Many CLMs track certificates from a single issuing CA. Red Sift consolidates certificates from all CAs, including those issued by other teams, for a complete view of your certificate footprint.
Discover certificates deployed across your estate, even those issued by third parties or embedded via external services. Correlate data from CT logs, IPs, hostnames, and DNS records to maintain a real-time inventory that reflects what’s truly in use.
Ingest and monitor every public certificate in real-time, with unmatched depth across subdomains, IPs, hostnames, and more. Go beyond daily scan schedules with continuous detection of new assets the moment they appear.
Unlike traditional CLMs that require weeks of complex integrations and set up, Red Sift Certificates deploys in minutes, enabling teams to act on certificate insights instantly.
