Next-generation firewalls(NGFWs) protect an organization from internal and external threats. A firewall system maintaining some features such as packet filtering, IPsec and SSL VPN support, network monitoring, and IP mapping features and NGFWs possess deeper content inspection capabilities. These capabilities provide the ability to identify attacks, malware, and other threats, and allow the NGFW to block these threats. NGFWs provide organizations with SSL inspection, application control, intrusion prevention, and advanced visibility across the entire attack surface. NGFWs not only block malware, but also include paths for future updates, giving them the flexibility to evolve with the threat landscape and keep the network secure as new threats arise. Next-generation firewalls are a vital component of implementing network security.
