Editor's note

Next-generation firewalls represent the next major step in the development of firewall technology, combining the functionality of a traditional firewall with intrusion prevention while also adding detailed application awareness into the mix.

Next-generation firewalls (NGFWs) bring additional context to the firewall's decision-making process by providing the appliance with the capability of understanding the details of the Web application traffic passing through it and helping it take action to block traffic that could exploit potential vulnerabilities.

This essential guide was designed to help enterprises better make firewall evaluations. It shows them how to cut through the marketing jargon of next-gen firewalls and make clear not only what an NGFW can provide in an enterprise setting but also help the organization determine which features to look for in an NGFW to ensure it best fulfills business needs.

1What can a next-generation firewall do for your enterprise?

An NGFW is good for more than just consolidating firewall and IPS functions into a single product. Next-gen firewalls also help manage and protect against traffic on unknown ports, help implement identity-based policies, and secure remote and mobile users.

Buying a next-generation firewall is a big decision to make, so don't jump in feet-first. Prior to making a buying decision, it is critical to know the criteria for making an evaluation on a number of factors, including integration, support options, functionality, product benefits and tradeoffs. Read on to learn more about these criteria and other "seal the deal" considerations.
