What does a firewall do?
Your firewall is responsible for guarding your whole network of electronic devices by blocking unauthorized access to your system while only permitting safe outward communication. This means a hacker trying to remotely access your computer will be blocked from your system. Likewise, if someone in your organization attempts to access an unsafe site, they will be blocked from reaching that site. The only communication it should allow is from users on your network to websites it has been told are safe.
With nearly two billion websites in existence, there are innumerable security threats lurking all over the internet. Your company doesn’t need to be left completely open to the entirety of the internet when you only need to access a certain number of websites to run productively and efficiently. Your firewall keeps your entire organization more secure. The more you can restrict, the less opportunity there is for a security breach.

Why does my firewall block me from everything?
If you get a secure firewall that offers a lot of robust features, it starts out with a very small radius of sites it considers safe to access. So, when you first implement your firewall, it’s likely to block you from going to websites you require. All you need to do is loosen some of the restrictions. Reach out to your IT support provider or department, we can program your firewall to suit your company's specific needs. It will also need to be maintained over time to combat new security threats.
Do keep in mind that your firewall is not infallible and you will need other pieces of the cybersecurity puzzle to keep your business secure. Every piece of protective software installed or hardware connected to your system does a specific job to protect your business.
