Overview

A firewall decides what traffic is allowed in and out of your network. A VPN lets people and offices connect securely over the internet. Set up well, they're quiet guardians. Set up badly, they either leave doors open or block the work you need to do.

We configure hardware and software firewalls, build secure remote access for staff working from home, connect multiple offices and set up intrusion detection. We work with equipment from vendors such as Fortinet, Cisco and Ubiquiti.

Frequently asked questions

Do I need a hardware firewall if my computer has one?

Computers have built-in software firewalls, which you should keep on. A hardware firewall protects the whole network, including devices that can't run security software, and is recommended for businesses.

Is a VPN the same as the VPN apps advertised online?

Not quite. Consumer VPN apps route your traffic through a provider's servers for privacy. A business VPN connects your staff securely to your own office network and systems.

Will a VPN slow down my connection?

There's some overhead, but with the right setup and equipment it's usually small enough not to notice for everyday work.

Can you check my existing firewall?

Yes. A rule review often finds old, unnecessary openings that should be closed.
