We live in a hyper-sensitive era when it comes to cyber-security. News of hacks and vulnerabilities are all over the news at the moment. We value cyber-security and it is our mission to make cyber-security a less daunting prospect for our users. To do so, we have made some helpful guides. Today we will cover firewalls. A firewall is relatively well known, but few really understand what it does.
Let’s understand the basics first – What is a firewall and what does it do?
Firewalls are commonly used to help prevent unauthorized access to both company and home networks. You can implement a firewall in either hardware or software form, or a combination of both. Firewalls prevent unauthorized internet users from accessing private networks connected to the internet.

We are now in a new era whereby just using a firewall to secure the perimeter of business networks won’t be enough, other measures need to happen which would go a long way in preventing cyber-attacks.
Businesses should regularly be reviewing security on company networks and looking at ways whereby they have the ability to scan traffic for both known and new threats at the same time using the next generation firewalls.
Clever cloud technologies can prevent threats along with effective management and monitoring of networks.
Anti-virus software is a must in addition to firewalls. But with so much on the market to choose from, how do you decide which is the best option for your business?
Decisions like these are based on how a company feels their current Anti-virus is performing, keys things to bear in mind:-
Did you know that some of the next general firewalls they have a mix of Anti-virus & Anti-spam with a licence associated with the firewall itself, but we still recommend that Anti-Virus software is installed.
When we look at network security, not only do we look at firewalls and antivirus software we also look at things like:-
