What actually is a Firewall?

We often talk about firewalls in cyber security conversations - but what are they?

A firewall acts as a barrier between your network/computer and the internet. It helps to keep your systems and the data stored on them safe.

We hope that this video helps to breakdown the technical jargon and gives you a good amount of knowledge to make informed decisions for for your business.

If you would like help assessing your firewall setup in your business, get in touch, we'd love to help.
