Following the discovery phase, the system manages TLS certificates, offering flexibility for both manual and automated request options, catering to various certificate-related tasks and processes.

The TLS certificate chains, signed by the certificate authority and root, populate the Unique Certificate \[cmdb_ci_certificate\] and Installed Certificate \[sn_disco_certmgmt_cmdb_installed_certificate\] tables. Subsequently, a
scheduled job reviews the Unique Certificate table for expiring and expired certificates, initiating the creation and assignment of certificate tasks and incidents.

You have the option to manually request new certificates and renew existing ones. For more information, see [Manual flow for certificate requests](https://servicenow-prod.fluidtopics.net/P9Mt4v6Fx5HMaKwpyYj2zg "Certificate renewal requests and incidents are automatically created when certificates are about to expire or have expired. For added flexibility and control, you can also manually create requests using the Service Catalog.").

In Version 1.3.8, the capability to automate requests for new certificates, renewals, or revoking certificates has been introduced. For more information, see [Automated certificate management for TLS certificates](https://servicenow-prod.fluidtopics.net/sG36IEmbAio1PbhSNQDsog "From Certificate Inventory and Management Version 1.3.8, you can automate the request flow for new certificates, renewals, and revoking certificates.").  
To optimize system performance, a table cleaner automatically removes old certificate records from these two tables after a specified number of days:

* Discovered Certificate \[sn_disco_certmgmt_certificate_history\] table: older than 30 days
* Installed Certificate \[sn_disco_certmgmt_cmdb_installed_certificate\] table: older than 90 days

Note:  
You can toggle various behaviors related to Certificate Inventory and Management depending on your needs, using specific certificate properties as shown in [Discovery properties](https://servicenow-prod.fluidtopics.net/6OmXtHd_W~setq24sqO8iw "Discovery properties allow you to control several aspects of the horizontal discovery process.") and [System properties](https://www.servicenow.com/docs/access?context=r_AvailableSystemProperties&version=yokohama&pubname=yokohama-platform-administration&ft:locale=en-US).
