Device42 supports auto-discovery of SSL certificates for easy tracking within Device42.
SSL Certificate Discovery Configuration
You can setup a new certificate discovery job by going to Discovery → Certificates, and then clicking “Add Certificate Autodiscovery Spec”. You can specify a range of addresses and one or more ports to check for the certificates. You can also set a schedule at this time to keep the discovery jobs running.
If a certificate is found on an IP address already associated with a device in Device42, the certificate will also be associated with that device automatically. Certificates that are discovered will then be available under Software>Certificates, and each device with a particular certificate will be listed in that Certificate’s detail page, or in Certificate Instances.
Note that certificate discovery can fail if MultiTenancy is enabled and the discovery job targets a VRF group whose subnet doesn’t existing within Device42. If you encounter this behavior, simply create the subnet that you are discovering within Device42 (or run a network discovery first, as reccomended by the best practices guide).
