PingCastle Enterprise License
PingCastle Enterprise licenses use one of two models: a legacy per-domain model or the current per-user model.
Configuration > Settings > Licensing shows which model the current license uses, along with usage against the licensed limit. You can also identify the model from the first three characters of the license key: PC2 for a per-domain license, PC3 for a per-user license.
- Per-user licensing
- Per-domain licensing (legacy)
Per-user licenses depend on the number of users you manage.

Per-domain licenses depend on the number of domains you manage, with licenses available up to unlimited. The number of domains includes subdomains of a forest.
- Licensing counts only domains, not Domain Controllers
- Licenses come in packs of 10 domains, up to 60, with an unlimited license thereafter
Example: If you have contoso.com with two subdomains called uk.contoso.com and us.contoso.com, this would require a 10-domain licensing pack.

Updating your license
Configuration > Settings > Licensing shows the current license and lets you apply a new one.
- Status — A read-only display of the license status, edition, and current usage against the licensed limit.
- Upload license — Upload a new license file to replace the current one.
