Excalibur are network security experts. We provide advanced managed firewalls, multi-layer VPN products and 2FA (two-factor authentication) solutions that keep your network safe.

Too many data breaches have hit the headlines, make sure you’re not one of them with Excalibur network security.

Barrier security is your first line of defence. It needs to be robust, carefully managed and able to protect you from intrusion, data loss and loss of system integrity. As the entry point for all network traffic

Managed firewall

A managed firewall acts as the cornerstone of your network security as it is the point at where all traffic enters your area of responsibility. Firewalls will be equipped with both proactive and reactive features, full reporting, traffic logging and management and be monitored 24/7. They are the ultimate protection for your network.

Excalibur’s managed firewall solutions are designed around your specific needs and can include hardware or virtual appliances with over 99.9% availability.

Multi-layer VPN

VPN, Virtual Private Networks are well-established methods of safely transporting data across the internet. Using a secure encrypted tunnel between the source and destination, you can confidently send confidential business data from one location to another.

Standard VPNs provide a high level of security for data in transit. Multi-layer VPNs take that one step further. Using MPLS layer-2 (switched) and MPLS layer-3 (routed) VPNs, data is as safe as it is possible to be while being transported.

Excalibur provides a range of VPN services to deliver the protection you need.


If you have ever had to enter a code sent via SMS to log into a website or enter a separate code from a keypad to log into internet banking, you have used 2FA (two-factor authentication). It is a valuable extra layer of protection that elevates network security to a whole new level.

By complementing the usual username and password with an extra authentication step that only a particular user has access to eliminates many of the risks to data and identity theft. Considering how straightforward and cost-effective it is to implement, it makes sense to include this into your security mix.

Each of these network security solutions can be used on its own. However, using all of them will elevate your network protection to a whole new level!
