In business you need to secure your computer network from internal and external threats. Next-generation firewalls (NGFWs) filter network traffic and are an essential element of network security. Having a firewall will maintain features of stateful firewalls like IPsec, SSL, VPV support, network monitoring, IP features and more.
NGFWs have more extensive content investigation capabilities to search deeper into your network to be certain your network is fully protected. These capabilities provide the ability to identify attacks, malware and other aspects that could possess as a threat to your network, then NGFWs can block any attacks should they occur.
By having NGFW they will provide organizations with SSL inspections, application control, intrusion prevention and advanced visibility across all the surfaces that could get attacked. With the threat landscape expanding rapidly because of co-location, multi-cloud adoption and business growth to satisfy customer needs, the traditional firewalls can fall further behind which will not be able to offer enough protection at scale which will then lead to poor user experience.
