A firewall is a security system for your computer network. It monitors and controls the incoming and outgoing network traffic based on security rules set by you. In other words, a firewall is a filter, between your internal network and the external network such as the internet, that protects your business network from unauthorized external access.
 

Does your network need a firewall?

 

Even though computers come with an inbuilt software firewall, your business isn’t safe with that single flimsy safety net. Network infrastructure devices are typical targets for cyber attackers and without a dedicated firewall, your network and all connected devices are vulnerable to hackers.

 

A dedicated hardware firewall gives your network a much-needed added layer of protection. The hardware firewall comes with advanced features such as VPN, Remote Access, and Advanced Web filtering. It is similar to a router in that it can handle a limited number of users. Therefore, make sure to get a firewall with enough capacity for future growth. 

A commercial-grade router usually comes with inbuilt firewall capabilities so you might not need to buy separate firewall hardware. Just make sure that you double-check this since it is critical for your network security.
