When discussing technology, there’s a good chance you’ve heard the term “firewall” more than once. But what exactly is a firewall, and why it is important to have a one in place for your business in Naperville, Hinsdale, or the surrounding suburbs?

What is a Computer Firewall?

Firewalls are software programs that offer network security. They prevent unauthorized access to and from private networks, and they filter incoming and outgoing traffic. Firewalls are put in place to reduce and/or eliminate unwanted communication, and they protect your IT infrastructure with an added layer of security to prevent malicious attacks on your servers.

If someone is trying to access your company’s computers, they’ll hit the computer firewall first. It will fend off the attack and warn you that someone is trying to gain access. Some firewalls will also alert you to suspicious outgoing traffic as well as the incoming traffic.

What If You Don’t Have a Firewall?

If you don’t put a firewall in place, your computer’s operating system is vulnerable to attacks. These can include harmful viruses, Trojans, popups, spyware, and malware. After undergoing so many attacks, your computer will become unusable.

Do You Have a Proper Firewall in Place?

If you’re not sure if you have a computer firewall in place or you want to ensure that you have the best possible protection, working with a managed IT services provider will give you peace of mind. Your outsourced IT support consultant will analyze and assess your current computer security systems and make suggestions for upgrades and improvements for firewall protection as part of your overall IT strategy.
