Certificates

Device42 tracks SSL certificates discovered across your infrastructure and lets you view validity details, associate certificates with devices and FQDNs, and run expiry reports. For details on creating a certificate discovery job, see Certificate Discovery.

Certificate List Page​

The certificate list page, under Applications > Certificates, shows all certificates discovered in Device42 along with their validity details.

Each certificate entry displays the following fields:

  • Serial Number
  • Key Encipherment
  • Key CERT Sign
  • Subject Alternative Name
  • First Detected date and time
  • Encryption method

You can export certificates by selecting them from the list and choosing Export Selected items as CSV from the Actions dropdown.

You can associate an FQDN, multiple devices, IPs, and different validity dates with a certificate. This is useful for wildcard certificates, where you can see all the FQDNs or subdomains associated with a single certificate.

Certificate Reports​

When a certificate has multiple valid-to dates, Device42 reports alert based on the oldest date stored for that certificate.

You can run reports to see which devices still need their certificates updated. This is especially useful in large deployments where you want to track update progress.
