I wanted to know if having two firewalls is usefull at all.
I'm an apprentice in a company and the I'm the only one in my company who knows little about networking. We have a cisco firewall and each computers have a kaspersky anti virus solution with a firewall. I have total control over it, however I'm rethinking about the utility of two firewalls.
At this moment, I didn't desactivate anything since the firewall was left on by an informatic company and since windows "want" a local firewall on each computers.
