A next-generation firewall (NGFW) is a network security device that provides capabilities beyond a traditional, stateful firewall. While a traditional firewall typically provides stateful inspection of incoming and outgoing network traffic, a next-generation firewall includes additional features like application awareness and control, integrated intrusion prevention, and cloud-delivered threat intelligence.
Gartner has named Cisco a leader in the 2019 Magic Quadrant for Network Firewalls.
A traditional firewall provides stateful inspection of network traffic. It allows or blocks traffic based on state, port, and protocol, and filters traffic based on administrator-defined rules.
A next-generation firewall (NGFW) does this, and so much more. In addition to access control, NGFWs can block modern threats such as advanced malware and application-layer attacks. According to Gartner's definition, a next-generation firewall must include:
The best next-generation firewalls deliver five core benefits to organizations, from SMBs to enterprises. Make sure your NGFW delivers:
The No. 1 job of a firewall should be to prevent breaches and keep your organization safe. But since preventive measures will never be 100 percent effective, your firewall should also have advanced capabilities to quickly detect advanced malware if it evades your front-line defenses. Invest in a firewall with the following capabilities:
You can't protect against what you can't see. You need to monitor what is happening on your network at all times so you can spot bad behavior and stop it fast. Your firewall should provide a holistic view of activity and full contextual awareness to see:
Whether you are a small to medium-sized business or a large enterprise, your firewall should meet your unique requirements:
The current industry standard time to detect a threat is between 100 to 200 days; that is far too long. A next-generation firewall should be able to:
Your next-generation firewall should not be a siloed tool. It should communicate and work together with the rest of your security architecture. Choose a firewall that:
