A firewall service review is not a box-ticking exercise for when something goes wrong. It is a practical check of whether the security device protecting your internet connection is still doing its job – stopping threats, supporting staff and keeping your business operating without unnecessary disruption.

For many businesses, the firewall was installed when the office first opened, when the internet service changed, or as part of a previous IT project. Since then, staff may have started working remotely, moved to Microsoft 365, added cloud applications, connected more mobile devices or introduced new systems such as practice management software. Each change can create a security gap if the firewall settings have not kept pace.

A proper review gives business owners and practice managers a clear answer to a simple question: can we rely on this part of our IT environment when it matters?

What a Firewall Service Review Should Cover

A firewall sits between your business network and the internet. It controls what traffic is allowed in and out, helping to block unauthorised access, malicious activity and risky connections. However, the device itself is only one part of the protection. Its configuration, software updates, monitoring and ongoing management are just as important.

A useful firewall service review looks at how the service works in your real business environment, not just whether a device has lights on the front. It should begin with the basics: the age and model of the firewall, whether it is still supported by the manufacturer, and whether its security subscriptions are current. A device that can no longer receive updates may continue to route internet traffic, but it is no longer a sensible security control.

The review should also examine the firewall rules. These rules determine which systems, services and users can communicate with the outside world. Over time, rules are often added to solve a short-term problem and then forgotten. An old remote access rule, an open port for a retired application or broad access granted years ago can become an unnecessary exposure.

Good firewall management means keeping rules specific, documented and regularly reviewed. If nobody can explain why a rule exists, it deserves attention before it becomes a weakness.

Security Features Are Only Helpful When They Are Enabled

Modern business firewalls can provide more than basic traffic filtering. Depending on the service and licensing, they may inspect web traffic, identify suspicious behaviour, block known malicious websites, control applications and support secure remote access for staff.

Not every business needs every feature switched on in the same way. A small office with a handful of local users has different requirements from a medical practice with multiple consulting rooms, cloud-based clinical systems and remote access needs. The aim is not to make the setup unnecessarily complicated. It is to ensure the protection matches the way your team works.

During a review, your IT provider should check whether security services are active, licensed and correctly configured. For example, web filtering may need to prevent access to known phishing sites, while intrusion prevention helps identify suspicious traffic patterns before they affect devices on the network. These controls are most effective when they are monitored and adjusted, rather than left on default settings.

Remote Access Needs Careful Attention

Remote work has made secure access a normal business requirement. Staff may need to access files, business applications or systems from home, on the road or between locations. Remote access can be convenient, but it should never mean opening the network to anyone with a password.

A firewall review should assess how remote users connect and whether multi-factor authentication is in place. It should also confirm that former staff no longer have access and that connections are limited to the systems each person actually needs.

For healthcare providers, this check is especially important. Patient information, clinical software and diagnostic systems can be sensitive and operationally critical. Access arrangements need to support clinicians and administration staff without creating shortcuts that put privacy or availability at risk.

Signs Your Firewall Service Needs Attention

A firewall problem is not always obvious. In many cases, business owners only find out there is an issue after a ransomware incident, an internet outage or a failed compliance check. A review is far more useful when it happens before a disruption.

There are several signs that it is time to look more closely at your firewall service:

• The firewall is more than a few years old, unsupported or no longer receiving firmware updates.
• Nobody can confirm who manages it, where its administrator credentials are kept or whether backups of its configuration exist.
• Staff use remote access, but multi-factor authentication is not consistently required.
• Your business has moved offices, changed internet providers, added cloud platforms or expanded to another location without reviewing network security.
• Internet performance is inconsistent, staff report blocked applications, or security alerts are regularly ignored because nobody owns them.
• Your organisation handles sensitive client, financial or patient information and needs confidence that access is controlled and recorded.

Any one of these points does not automatically mean your firewall has failed. It does mean the service should be assessed by someone who can explain the risks in plain language and recommend practical next steps.

What Good Firewall Management Looks Like

The best firewall service is not necessarily the one with the longest feature list. It is the one that is correctly sized, actively managed and supported when your business needs help.

That starts with clear ownership. There should be a named IT provider or internal contact responsible for updates, security alerts, configuration changes and escalation if the firewall goes offline. Businesses should also know what support is available outside standard hours, particularly if internet access affects bookings, payments, cloud applications or patient care.

Configuration backups are another essential part of good management. If a firewall fails or needs replacing, a current backup can reduce recovery time significantly. Without one, the replacement process may involve rebuilding settings from scratch while staff wait to reconnect.

Network segmentation is also worth considering. This separates different parts of the network so a problem in one area does not automatically spread everywhere else. For example, staff computers, guest Wi-Fi, security cameras, phones and specialised medical equipment may not need to sit on the same network segment. The right approach depends on the size and complexity of your environment, but separation can limit the impact of compromised devices and reduce unnecessary exposure.

Regular reporting helps turn security management into an ongoing service rather than a once-a-year task. Reports do not need to be overly technical. They should show whether updates are current, whether threats have been blocked, whether any issues need a decision from the business, and what work has been completed.

Questions to Ask During a Firewall Service Review

You do not need to be an IT expert to assess the quality of a firewall service. Ask your provider straightforward questions and expect clear answers.

Can you confirm whether our firewall is still supported and receiving security updates? Which security services are enabled, and what risks are they designed to reduce? Who reviews alerts and how quickly are serious issues escalated? Are our remote access settings protected with multi-factor authentication? When was the configuration last backed up and tested? Which firewall rules are no longer needed?

It is also reasonable to ask what happens if the hardware fails. Some businesses can tolerate a few hours without internet access; others cannot. A practice relying on cloud-based records, online bookings and EFTPOS may need a faster replacement plan or a backup internet connection. The right level of cover depends on the cost of downtime to your organisation.

A good provider will not push a replacement simply because a newer model is available. They will explain whether your current firewall is suitable, where the risks are, and whether maintenance, reconfiguration or replacement is the most cost-effective option.

Make Firewall Reviews Part of Business Continuity

Cybersecurity and business continuity are closely connected. A firewall can help prevent an incident, but it also supports recovery by controlling access, maintaining secure connections and reducing the chance that one compromised device affects the whole network.

For this reason, firewall reviews work best when considered alongside backups, malware protection, user access controls and incident response planning. A business with strong backups but poor network security still has staff downtime and recovery costs to manage. A business with an excellent firewall but no tested backups may still struggle if systems are encrypted or data is lost.

At Onsite Technology Solutions, we approach firewall support as part of the wider IT environment. That means looking at the devices, users, cloud services and business applications that depend on your network, then keeping the protection practical and manageable.

The most helpful outcome from a review is not a long technical report. It is a clear plan: what is working, what needs fixing now, what can be improved over time, and who is responsible for each step. When your firewall is properly managed, it stays in the background where it belongs – helping your team get on with their work.
