I don’t need a firewall – I’ve got antivirus…. Right?


You're either secure or you're not, there is no middle ground when it comes to having proper network security.

An antivirus program is not the same thing as a firewall and it’s important for businesses to realise that buying a firewall is not a pointless exercise.

An assumption that is often made by smaller companies is that they are not a target for hackers because they are too small. Bigger companies assume that they are already protected or somebody else is *looking after IT*

Just assuming you won’t be affected won’t keep you safe and as more and more records are leaked through information hacks, it’s prudent to start looking for a solution to ensure you are protected from today.

Businesses of all sizes, small and large, are vulnerable to viruses, hacking and data leaks, and it’s easy to take the few simple steps to ensure that you are well protected against this growing threat.

Choosing the right size firewall is important, so make sure you do your research beforehand as to what you need, don’t just rely on a vendor to tell you, as one vendor will probably quote a totally different size to the next. Use a vendor sizing guide as just that – a guide.

We recommend that you think about your individual infrastructure, and not compare yourself to another company.  Take time to see how your network users work, what a typical use-age pattern looks like, which applications they use and the servers you need to protect. Decide which features you are likely to want to use daily.

 Traditional port-based firewalls only provide you with limited control and visibility of the applications and end-users accessing your network, but you might not want everyone accessing applications like Instagram, YouTube or Facebook. You might however, want your social media or marketing team to be able to connect to these sites.

With the right firewall in place, you can apply policies to certain end-users, allowing access to those with jobs pertinent to the applications being used, and denying access to those who have no business updating their social media accounts whilst at work, or set a policy as to what you might want guests to be able to connect to.

Did you know – that if you use a traditional port-based firewall, you cannot see who is accessing your network, or the applications that might be gaining access. With all the data breaches we are seeing, that is a problem, as how will your network stay protected?

A next-gen firewall can limit traffic and risks by allowing approved only applications, as it can see and control all your sensitive information on the wireless network.

The next-gen firewall is also capable, of finding a device by user name, rather than an IP address, so you know exactly how many devises your employee is using to access your network, and if you need to you can find and wipe the device so a breach can be avoided.

BYOD – bring your own device, is allowed by more and more employers, allowing remote working in almost every industry.  These employees might need to connect remotely from home, a customer base, or even a coffee shop while on their lunch, but you should ensure that the same rules and policies are set on the firewall and enforced as such outside of the main workplace.

Next-gen firewalls already have the necessary security infrastructure components built-in, which includes, Anti-virus protection, spam filtering, deep packet inspection, application filtering, which means you don’t have to spend more money or extra applications or hardware.

It's a comprehensive security component that enables you to not have to worry about what other pieces you’ll need to add to make your network more secure.

We recommend Barracuda Next Gen Firewalls, purpose built for a modern distributed network where your performance and availability are just as important as your security. Being application aware, unlike traditional firewalls, means you can regulate application use-age and prioritise network traffic.
