School Firewalls

A school firewall controls how your network behaves day to day — protecting users, managing access and keeping systems available. Wave9 provides managed and co-managed firewall services built on Sophos and supported by engineers who understand how school environments work.

Why Firewalling Matters in Schools

Schools rely on their network for teaching, safeguarding, administration and communication. That means the firewall is not just a security tool, it is a key control point for how the environment runs.

It determines what traffic is allowed, how users and devices are handled, and how services connect across sites and systems. If your firewall is poorly configured or has evolved without review, it can create risk, reduce visibility and make day-to-day management harder than it needs to be.

We’ve got a strong internal team… but where Wave9 really come into their own is the specialist areas like firewalls and cyber security.

How Wave9 Approaches School Firewalls

Wave9 delivers firewalling as a managed or co-managed service, depending on how much control your school or trust wants to retain.

Schools with in-house IT teams can stay hands-on, with direct access to Wave9 engineers for support, changes and more complex work. Where internal capacity is limited, Wave9 can take on day-to-day management while keeping everything visible and understandable.

Built on the Sophos XGS platform, the service covers policy management, traffic control, routing, remote access and resilience. The focus is not just installation, but making sure the firewall remains clear, usable and properly supported over time.

Control and Resilience: Cloud vs On-premise

Cloud-managed services can be convenient, but they do not always give schools the control or resilience they expect.

In many cases, multiple internet connections still depend on the same central platform. If that platform has an issue, both connections can be affected.

An on-premise firewall allows schools to manage traffic locally, support true failover between independent connections and maintain clearer control over policies. Wave9’s co-managed approach keeps these benefits while removing the burden of managing everything alone.

Built to Support Schools in Practice

When network issues affect a school day, schools need speed, clarity and direct access to someone who can act.

Wave9 provides direct access to experienced engineers who can investigate issues, explain what’s happening and take ownership. This is especially important where your configuration has evolved over time or internal IT capacity is stretched.

You can read more about how this works on our Support and Service page.

A Firewall Review Can Be Useful Before Renewal or Change

Firewall setups often build up over time, with rules, exceptions and access changes accumulating.

A review can help you understand how your current configuration works, identify unnecessary complexity and check that it still reflects current needs.

If that sounds familiar, our Firewall Audit page explains what a structured review can cover.
