Do you know whether your firewall is correctly configured and fully up to date?
Many businesses install a firewall and assume the job is done. In reality, an incorrectly configured or poorly maintained firewall can leave your network exposed. In some cases, it can be just as risky as having no firewall at all.
What Is a Firewall?
A firewall is a security system designed to control traffic entering and leaving your network. It works by applying rules that decide which connections are allowed and which should be blocked.
Firewalls are essential for preventing unauthorised access to internal systems, protecting sensitive data, and reducing the risk of cyber attacks originating from the internet.
Why Firewall Management Is Often Overlooked
Firewalls are not a “set and forget” solution. Over time, networks change, applications are added, and threats evolve. Without regular review and maintenance, firewall rules can become outdated or misaligned with your business needs.
This can result in:
- Traffic being allowed when it should be blocked
- Legitimate services being disrupted
- Security gaps caused by outdated firmware or rules
- Compliance failures due to misconfiguration

Protect Your Network with Expert Firewall Management
A correctly installed and professionally managed firewall is one of the strongest defences you can have against online threats. It acts as a gatekeeper between your internal systems and the wider internet.
Managed firewall services ensure that this protection adapts as your business and threat landscape change.
Free Up Time Without Compromising Security
Firewall management requires specialist knowledge and ongoing attention. Most business owners did not start their company to spend time reviewing firewall logs and adjusting access rules.
By outsourcing firewall management, your team can focus on running the business while experienced engineers handle the security.
Supporting Compliance and Regulatory Requirements
Many data protection and security standards rely on properly configured firewalls. For example, PCI DSS requires firewalls between payment systems and the internet.
Managed firewall services help ensure that policies remain aligned with these requirements and that changes are documented and monitored.
