ABOUT THIS SERVICE

Your network connects every device, every user, and every system in your business. A single misconfiguration or unmonitored connection is all it takes for an attacker to get in. We make sure they can't.

Firewall Configuration and Management

A properly managed firewall is your first line of defence. Most businesses have firewall rules that haven't been reviewed in years — we fix that.

  • Firewall configuration and ongoing rule management
  • Legacy rule audit and cleanup
  • Traffic filtering and application control
  • Inbound and outbound threat blocking
  • Regular configuration reviews and documentation

Remote Access and Zero Trust

Remote and hybrid working is now standard — which means securing connections from outside the office is just as important as securing what's inside it.

  • VPN setup and management for remote teams
  • Zero Trust Network Access (ZTNA) implementation
  • Per-user access controls — staff only reach what they need
  • Encrypted connections from any device, any location
  • Remote access auditing and session logging

Continuous Network Monitoring

Threats on your network don't always announce themselves. Our monitoring detects unusual behaviour and suspicious activity before damage occurs.

  • Continuous network traffic monitoring
  • Intrusion detection and prevention (IDS/IPS)
  • Anomaly detection and alerting
  • Network segmentation — isolating sensitive systems
  • Guest Wi-Fi separation from internal networks

Network Security — Frequently Asked Questions

Do I need network security if I'm mostly in the cloud?

Yes. Cloud environments have their own network security requirements and misconfiguration is one of the most common causes of data exposure.

How do I know if my network has already been compromised?

Many compromises go undetected for months. A network security assessment can identify indicators of past or ongoing compromise. Contact us to arrange a review.

What's the difference between a firewall and a network security service?

A firewall is one component. A managed service covers firewall management, monitoring, access controls, and ongoing assessment — defence in depth rather than a single control.
