Intruder's pricing consists of a fee for the basic service, and our prices increase by a small amount per extra target you'd like to cover. This small extra charge is the 'per-target fee'.
Once you've signed up for a free trial, you can use the pricing calculator at https://portal.intruder.io/signup to determine the cost of your subscription.
Just move the slider to the number of systems (e.g. IP addresses or hostnames) or targets you want to protect and it'll show you the cost for each plan.
