The Network Enterprise Firewalls are defined as standalone purpose-built firewall appliances with IPSec VPN capabilities, capable of delivering extensive firewall and management capabilities for securing the perimeter access. Enterprise firewalls incorporate also IPS technologies, replacing perimeter IPS as well. Further integration with more application and user awareness protection capabilities are also emerging on these firewalls. This combination is known as Next-Generation Firewalls.

Enterprise firewalls must be able to secure an increasingly complex network that includes traditional on-premises data center deployments, remote offices and a range of cloud environments. Perhaps the only element more complex than configuring, testing and managing a next-generation firewall is the decision-making process regarding which product to trust with your enterprise security.
