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 across your certificates by combining real-time monitoring of the Certificate Transparency ecosystem with discovery across hostnames, services, and private infrastructure.
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.
Why security teams choose Red Sift Certificates
Fast, frictionless deployment with nothing to install
Unlike traditional CLMs that require weeks of complex integrations and setup, Red Sift Certificates deploys in minutes, enabling teams to act on certificate insights instantly.
Access the deepest, freshest certificate data
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.
See every certificate in use—including those beyond your control
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.
Discover private certificates trusted inside your environment
Safely uncover certificates issued by private or internal CAs and surface hidden dependencies across internal applications and services that external discovery can’t see.
Gain visibility across all Certificate Authorities (CAs)
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.
Understand your PKI posture with detailed configuration insights
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.
Spot misconfigurations and rogue certificates before they become threats
Continuously monitor deployed, unused, and newly issued certificates to surface misconfigurations, expired certificates, and suspicious issuances early before they lead to outages or breaches.

A closer look at how Red Sift Certificates works
"Red Sift Certificates enables William Fry to achieve the best possible security configurations on all of its hosts and domains across the web and email whilst also closely monitoring both our own public certificates, as well as our vendor certificates."
"Using Certificates helps Denic as we can see the configuration of our infrastructure in real-time, receive notifications about certificate issues before they impact on production, and receive useful analysis when a problem does occur that helps us to get to a fix quickly."
"We rely on Red Sift Certificates to identify when our digital certificates are due to expire. We can easily inspect certificate details along with the endpoints that were discovered serving them without resorting to low-level debugging tools."
"Coop uses Red Sift Certificates to gain better visibility of our exposure on the internet. We use it to discover and monitor all of our cloud apps and third-party certificates. It also helps us validate our WebServer settings such as CSP and HSTS headers to harden our configurations."

Private PKI Monitoring now available
Private PKI Monitoring expands certificate visibility beyond the public internet and into private networks and internal environments. This release helps teams close long-standing visibility gaps in private PKI and manage certificates more consistently across modern, hybrid infrastructure.
Frequently Asked Questions
It helps prevent outages and risk by tracking certificate inventory, expiry, and unexpected changes across your estate.
Monitoring focuses on visibility and alerting (what exists, what’s expiring, what changed). CLM focuses on issuance/renewal orchestration and automation workflows.
Use automated discovery (domain + network + CT log visibility) to build an inventory, then assign ownership for remediation and renewal.
Discovery first—automation is powerful, but you can’t automate what you haven’t inventoried and assigned owners to.
