Firewalls have long been a staple of enterprise security. They have played a key role in filtering content and protecting IT systems. But in today’s high-risk business landscape, first and second-generation devices aren’t enough to protect against increasingly sophisticated attack methods. They also don’t reflect the needs of organizations in the cloud. As a result, organizations large and small are adopting more advanced next-generation firewalls (NGFW).

Next-generation firewalls combine conventional firewall protections with more sophisticated features, including in-line deep packet inspection, intrusion detection and website filtering. According to Research and Markets, the next-generation firewall market is projected to grow at a CAGR of over 12 percent between 2018 and 2023. The growth of NGFW’s revolves around their ability to address web-based exploit kits, sophisticated malware, application-layer attacks, and highly targeted threats.

Here are the top vendors in the NGFW space, according to eWEEK. Vendors appearing in this guide scored high on the Gartner MQ and Gartner Peer Review sites. Other sources included NSS Labs, vendor websites and our sister site, eSecurity Planet. For more information, see our top security vendor methodology.
