Certificate Cisco ASA 5545

[jonesch]

I was just informed that the certificate inside of my ASA will be expiring soon, What type of certificate should I be looking to purchase to replace it with?

Hi

I believe this is the certificate for ssl vpn.
You can purchase any public ssl certificate (basic domain validation).
Or you can look at let's encrypt that allows you to enroll free public certificates. However they're only valid for 3 months but you can script it to renew it automatically.
