View detailed information about each certificate in your inventory.

The Certificates tab in the Inventory displays all certificates that Cortex Xpanse has attributed to your organization and whether Cortex Xpanse has seen each certificate advertised recently. The Certificates list view also indicates whether the advertisement is associated with an active service. If you have integrated cloud accounts, this tab will show you which certificates have associated managed cloud resources.

Cortex Xpanse tracks the following information for each certificate:

  • Issuer, Issuer Country, Issuer Organization, Issuer State

  • Public key, Public Key Algorithm

  • Subject, Subject Alternative Names, Subject Organization, Subject Country, Subject State

  • Serial Number

  • Valid Not Before, Valid Not After

  • Version

  • Common Name

Additionally, Cortex Xpanse automatically tracks the following “cryptographic health” checks for certificates:

  • Is Self-Signed?

  • Is Wildcard?

  • Is Domain Control Validated?

  • Expired When Scanned?

  • Public Key Bits

  • Signature Algorithm

These health checks are referred to in Expander as Certificate Classifications.
