Safety first

Our managed firewall service gives you the peace of mind that comes from a flexible, well-resourced, strategic security solution delivered and maintained by experts.

  • Evolving defences. We invest in real-time updates on global security threats – and how to tackle them – as they emerge, pre-emptively defending against them before they become a problem.
  • Real-time responsiveness. Our 24/7 Operations Centre proactively monitors your networks round-the-clock, enabling us to take swift action against potential firewall breaches, minimising their impact.

A firewall is a network security device or software that acts as a barrier between a trusted internal network and untrusted external networks, such as the internet.

The main function of a firewall is to analyse and filter network traffic based on a set of predefined rules. As data packets pass through, the firewall examines them and determines whether to allow or block them based on things like source and destination addresses, ports, and the type of traffic. This helps to prevent unauthorised access, protects against malware and cyber attacks, and establishes a secure perimeter for the network.

A managed firewall is a firewall system that is outsourced to a third-party service provider for monitoring, maintenance, and ongoing management. In a managed firewall arrangement, the service provider is responsible for configuring the firewall settings, updating security rules, monitoring network traffic, and responding to security incidents.

The key distinction between a managed and unmanaged firewall lies in the level of oversight and responsibility for the firewall’s operation. In an unmanaged firewall scenario, the organisation is solely responsible for configuring, monitoring, and maintaining the firewall. However, a managed firewall involves outsourcing these tasks to a service provider.

Having a managed firewall allows organisations to focus on its core business while still benefiting from robust network security. It provides access to specialised expertise and the continuous monitoring and management offered by a managed firewall service enhances the organisation’s overall security posture. Outsourcing firewall management also enables quicker response to emerging threats, reducing the risk of security breaches. Additionally, organisations benefit from cost savings and resource efficiency, as they no longer need to hire and train in-house personnel for firewall management.
