The basics

What Is Network Security?

Network security is the set of tools, settings, and processes that protect your business network from unauthorised access, misuse, and attack. It covers everything from your firewall and Wi-Fi to how remote staff connect and how traffic is monitored.

Done well, it stops threats at the edge of your network, limits how far an attacker can move if they do get in, and spots unusual activity early.


Why test

Most businesses now work across offices, homes and the cloud. Every laptop, Wi-Fi network, and remote connection is a possible entry point.

stop attacks before they disrupt your business

give staff secure access from anywhere

Our services

Our Network Security Services

Managed Firewalls

We supply, configure and manage business-grade firewalls, including WatchGuard, to control what enters and leaves your network.

Secure Remote Access and VPN

Give your team safe access to company systems from home or on the move, with encrypted connections and multi-factor authentication.

Secure Business Wi-Fi

Separate staff and guest Wi-Fi, strong encryption, and access controls, so visitors and personal devices never reach your business systems.

Network Segmentation

We split your network into secure zones, so if one area is compromised, an attacker can’t move freely to your servers, finance systems, or sensitive data.

Web and DNS Filtering

Block access to malicious and unsafe websites before they load, cutting the risk from phishing links and harmful downloads.

Network Monitoring and Threat Detection

We monitor your network for unusual activity and respond quickly. Add managed detection and response (MDR) for 24/7 monitoring.

Vulnerability Scanning

Regular internal and external scans find weak points in your network, with a clear plan to fix them.

Network Security Audits

A full review of your current network, firewall rules, and Wi-Fi setup, with plain-English recommendations ranked by risk.

FAQs

Network Security FAQs

What is network security?

Network security protects your business network from unauthorised access and attack, using firewalls, secure Wi-Fi, remote access controls, filtering and monitoring.

Do we still need a firewall if we use Microsoft 365 and the cloud?

Yes. Your office network, Wi-Fi and connected devices still need protecting, and a firewall is one of the five Cyber Essentials controls.

Do you support WatchGuard firewalls?

Yes. We’re a WatchGuard partner and have delivered multi-site WatchGuard firewall migrations for clients.

Can you secure remote and hybrid workers?

Yes. We set up secure remote access, VPNs, and multi-factor authentication, so your team can work safely from anywhere.

How much does network security cost?

It depends on your number of sites, users and hardware. Book a Free IT Health Check, and we’ll recommend the right setup with a clear, fixed quote.
