Check Point UTM-1 was a firewall solution that unified threats. The use of this tool was as an on-premise device since we needed security in the network to control incoming and outgoing traffic working in conjunction with security policies. It also features additional items, such as the antivirus capabilities that we implement on all devices, as well as intrusion prevention and VPN capabilities. It is an excellent tool that helped us to solve all the vulnerability problems that we presented while reducing security gaps.
Checkpoint is the most complex firewall/UTM/NGFW among the vendors I worked with compared to Fortinet / SonicWall / Netasq. The product is stable and comes with many amazing features even most of them costing money but with these features, you can easily get better viability of your network(s).
