Is a router a firewall?

Yes, the rumors are true: wireless routers automatically do the job of a basic hardware firewall.

Firewalls are designed to repel any external internet traffic that tries to gain access to your internal network (a.k.a. the network of devices connected to your router). This is a common technique used by hackers; once they get access to your network, they can steal sensitive data (like employee records and customer payment info) and control devices like wireless security cameras.

Routers help prevent this kind of infiltration because they were designed to manage outgoing traffic requests. If the router receives an incoming traffic request that isn’t initiated by a device on your network, the router discards it automatically. That keeps anyone outside your network from accessing your devices, so you get built-in protection from basic-level cyberattacks.
