We use it for the actual firewall and also site-to-site VPN.
Our company is always growing. Every day's a new day and there is always something new to learn. We are a mature organization, but we can never sit still. We have two company locations and we use Cisco Firepower as our main firewall at both locations.
Overall, for security, we use about seven tools.
Within our company, there are just two people that maintain this solution. Myself and the IT manager. I'm the network administrator.
