We live in an age of deep internet penetration and global outreach. And in this modern era, cyber security threats pose a greater danger to your business’ assets and that all-important entity, data.

Almost all modern business has an IT and internet-based infrastructure in place to help them communicate and achieve objectives quickly and reliably. However, internet connectivity brings with it inherent risks because there are malicious elements always looking to wreak havoc with your business. That’s where a good firewall can really help.

Almost every one of us has heard of the term firewall. But really, what is a firewall? And what is it used for? Is it some sort of an anti-virus? To put it simply, a firewall is the first line of defense that operates with the sole purpose to protect your computer and network from cyber-security risks that can emanate from the internet.

A firewall works by acting as a sort of barrier between your network and the outside internet. It does so by scanning the incoming and outgoing data (packets). A good firewall has built-in customization rules and pattern detectors that are able to detect any irregular or non-routine activity which would normally signal malicious activity.

Protect Your Network and Computers from Unauthorized External Access and/or Hackers

A firewall is a preemptive measure that every business should take in order to safeguard their network and data. A good firewall will detect any suspected activity and will block the source of that activity from reaching your network. An anti-virus will NOT serve this purpose, only a firewall is able to block incoming traffic or data to your network.

Restrict Access to Websites

If you’re the owner of a business and are constantly worrying about your employees slacking off by using social media websites like Facebook, a firewall can come in especially handy. Using a firewall, you can setup a policy which will block all outgoing and incoming traffic to certain websites from your network.

Protect Sensitive Data from Being Accessed

When you’re connected to the internet, you deal with both incoming and outgoing internet traffic. Malicious sources can use incoming traffic to take control of your computer or network. However, monitoring of outgoing traffic is just as important, as it can include your account passwords, credit card details or social security number. A good firewall does not just block incoming access from potential hackers or malicious sources. It will monitor outgoing traffic as well, and will detect and block access from any sources it suspects are trying to ‘sniff’ the outgoing data.


A good firewall provides the critical first line of defense your network infrastructure needs to protect itself from digital threats such as intruders and malicious code that are ever-present on the internet. As a business owner, you should consider investing in a hardware firewall as they provide the greatest level of security by filtering data at the packet-level.
