A common misconception about firewalls is that they are only necessary for large companies or financial corporations. In reality, every business that has a network should have a firewall, regardless of the size of your company.
Over half of all cyberattacks today are targeted at small businesses, because smaller businesses typically have a myopic view that cybercriminals will not target at them. Hence, they have lesser or rudimentary network security which in fact makes them the easiest prey. Also, cybercriminals are continually evolving their strategies and finding new, more sophisticated ways to penetrate through the network security, and steal your company’s most valuable asset – your data.
Thus, this is where the firewall earns its keep.
