Frequently Asked Questions

While there are many types of software-based firewalls used today, they all aim to provide overall network security. Firewalls provide network security through a gateway process that acts as a filter for all incoming packets. With pre-defined rules and logic, each packet that enters (or that tries to) the network will be analyzed in order to determine whether it contains malicious code or not. Some of the most commonly used software firewalls are packet filtering, circuit-level, proxy server, stateful inspection, and next-generation firewalls (NGFW).

Firewalls act as a gateway between external internet resources and internal devices using a private network. They filter incoming packets in order to identify malicious file types and access. In doing so, software firewalls provide effective security for all resources connected to a private network.
