We use Venafi for creating and renewing our enterprise certificates which provides us the identity and verifies if the system/user is trusted or not. Without certificates the site won't be accessible over https if it is SSL and other viceversa.
I like it because it is easy to use and learn faster, provides customization, certificate lifecycle management is best we can create and get notifications if they are expiring so we can renew and force a new one which is good for uninterrupted services, it allows policy enforcement for organizations. Customer support is also good but it could be better. Review collected by and hosted on G2.com.
The cost is high compared to other products but it comes with high vendors support currently it renews for only one year before it used to be 2 years for our web dispatchers which is becoming more work once a year. Review collected by and hosted on G2.com.
