Next-Generation Firewall (NGFW)

Securing your enterprise starts with your firewall. Time has moved forward from legacy security to prevention-based architectures that evolve with your business. Next-generation firewalls have been redefining network security for 15 years and are a must for today's digital world.

Today gateway computers serve much the same purpose but instead of translating communication protocols they often function as DNS/DHCP servers and translate addresses taking the single IP that a site may own and then figuring out which computer to route that packet to. This is done by routers as well, many home routers have built-in DHCP servers to allow you to connect multiple computers.

A firewall is a software or hardware appliance the blocks, filters, or in some way restricts and to a degree directs network traffic. Typically the firewall would be used to selectively block connections to various ports on local machines that the admin didn't need. It may allow ssh connections to 22 but only from a certain IP block or it may not allow any traffic on ports commonly associated with P2P networks.

Network Firewalls, especially Next-Generation Firewalls, focus on blocking malware and application-layer attacks. Along with an integrated intrusion prevention system (IPS), these Next Gen Firewalls are able to react quickly and seamlessly to detect and react to outside attacks across the whole network. They can set policies to better defend your network and carry out quick assessments to detect invasive or suspicious activity, like malware, and shut it down.
