Best for: Teams already running Fortinet security
It belongs here because one product ships in three forms, so you can cover older and newer apps the same way, and its checks on scripts in payment pages help with PCI DSS. If you already run FortiGate, it shares that ecosystem. If you do not, weigh whether you want one more vendor console in the mix.
