A firewall is a vital piece of your business’s defense against electronic threats. Serving as a gatekeeper between your company’s servers and the outside world, a properly maintained firewall will not only keep external threats out, but it can also alert you to subtler problems by intercepting outgoing data as well. Paired with a well-maintained anti-malware suite, a firewall can save your business from spending time and money dealing with virus infections or hacker attacks.
A solid firewall will help you stop intruders from accessing your system. You keep your internet link to the outside world but the outside world can’t view you unless you want them to. With a firewall in place you will still have typical email access, but chat and other interactive programs will require you to take an extra step to grant access before you can use them. A firewall is powerful but unobtrusive, just like a deadbolt lock inside a door.
