A firewall is most crucial for a secure internet connection as it prevents unwanted users from hacking into and accessing your connection. Firewalls come as two kinds; Network Address Translation (NAT), and Stateful Packet Inspection (SPI). While NAT caches the computer’s IP address behind the router’s IP address, the SPI checks every data packet to ensure it is part of a legitimate connection. The best routers with a firewall also support some advanced wireless security measures to safeguard business assets.
