Full onsite deployment of firewall hardware, DNS filtering, and endpoint hardening. Ongoing monitoring and maintenance included.

In Northern Ireland, we deploy the full security stack onsite. That means a physical firewall with IDS/IPS enabled, a dedicated DNS filtering server blocking over 2 million malicious domains, VLAN segmentation isolating different device types, and endpoint hardening on every workstation. Then we monitor and maintain it remotely as part of an ongoing support arrangement.
This is not antivirus software. It is layered network security deployed as infrastructure, managed and maintained by the same person who installed it.
Small businesses in Northern Ireland face the same phishing emails, ransomware campaigns, and credential theft attempts as large enterprises. The difference is that large companies have dedicated security teams. Small businesses typically have nothing beyond the default settings on a consumer router and whatever Windows Defender does by default.
A managed firewall and threat prevention setup closes that gap. It does not make you invulnerable, but it blocks the vast majority of common attacks before they reach your staff, and it gives you visibility into what is happening on your network that you currently do not have.
Antivirus runs on one device and catches threats that have already reached it. Managed firewall and DNS filtering block threats at the network boundary before any device is exposed. They work at different layers:
All three layers run simultaneously. If one misses something, the next catches it.
Full onsite deployment (hardware installation, server setup, VLAN configuration, endpoint hardening): all of Northern Ireland.
Ongoing monitoring and management: remote, included in the support arrangement.
For businesses outside Northern Ireland who want the remote monitoring and DNS filtering without onsite hardware deployment, see our Ireland-wide remote firewall and threat prevention page.
Tell me what you have. I will check your current router, DNS setup, and endpoints, and tell you what is exposed. Onsite across Northern Ireland.

A managed firewall sits between your internet connection and your internal network. It blocks unauthorised access attempts, filters DNS requests to prevent staff reaching known malicious websites, monitors all network traffic for suspicious patterns, and logs everything for review. Unlike a consumer router, it actively inspects traffic rather than simply forwarding it.
For businesses on a support contract, managed firewall and DNS filtering is included at no extra charge. As a standalone service, pricing starts from around £30 to £60 per month depending on site size, number of devices, and whether onsite hardware deployment is required. We will quote based on your specific setup after a quick site review.
Yes. Antivirus and firewalls protect at different layers. Antivirus scans files on a single device after they arrive. A firewall blocks threats at the network boundary before they reach any device. DNS filtering stops your machines connecting to dangerous websites in the first place. Think of it as locking the front door (firewall) versus having a guard inside each room (antivirus). You need both.
DNS filtering checks every website request against a list of known dangerous domains before the page loads. If someone clicks a phishing link or visits a compromised website, the connection is blocked before any content reaches their device. It protects every device on your network automatically, including phones, printers, and IoT devices that cannot run antivirus software.
We use automated alerting that flags suspicious activity in real time: unusual DNS queries, repeated failed login attempts, and traffic to known bad destinations. Our DNS filtering blocks over 2 million malicious domains, updated regularly from multiple threat intelligence feeds. Firewall firmware is kept current, and monthly reports are available showing what was blocked and any recommendations for your network.
