How many sites is my licence valid for ?

SecuPress and licences

When you buy a licence, you choose the number of sites you want to install SecuPress on. You can choose 1, 3, 10, or an unlimited number of sites, depending on your need. A single site licence can be active for a single site, and so on.

If you run a multisite, a single licence is enough because it activates on the whole network. The plugin affects every single site at once, and it is not possible to not activate SecuPress on an individual site of the network.
