Our company does internal PEN testing which enerates A LOT of IPS alerts. How can I whitelist the IP?

Thank you.

You can add it as an exclude host

Setting up a list of excluded computers

Thank you for the advice. But my security folks don't want to exclude the traffic. Maybe there's a way to allow the traffic but silence emails?

Disable the alerts or exclude the host. Not really any other options than those.

Were you able to get this resolved?
