Managed Firewall & Network Security
Your firewall selected or taken over, its rules reviewed and controlled, firmware current, intrusion prevention and web filtering on, remote staff connected securely, and the network segmented so a compromised camera cannot reach the accounting server.
Overview
The firewall was configured on install day. The business has changed every week since.
Managed firewall services solve a problem almost every small business has and few know about: the firewall was set up once, by whoever installed it, and has not been looked at since. Rules were added for a vendor's remote access and never removed. Firmware is years behind. The intrusion prevention subscription expired. The guest Wi-Fi is on the same network as the file server, and so are the security cameras, the thermostat and the card terminal. The box is still passing traffic, which is why nobody has noticed.
We manage the firewall as an ongoing service rather than an install. That starts with selecting and supplying a next-generation firewall sized for your connection and staff, or taking over the one you have — Fortinet, SonicWall, Cisco Meraki, Ubiquiti and WatchGuard are the lines we manage most. Then the work that keeps it effective: a rule review to remove what nobody can explain, change control so every new rule is requested, reviewed and logged, firmware and security updates applied in maintenance windows, intrusion prevention and web filtering kept licensed and tuned, geo-blocking for countries you do not do business with, a VPN or zero-trust access for staff working remotely, and segmentation that puts guests, cameras, IoT devices and payment terminals on their own networks. Logs flow into our monitoring platform, failover is tested, and the whole thing is documented with a diagram you can hand to an auditor.
Capabilities
What's included
- Firewall selection, supply or takeoverA next-generation firewall sized for your business and configured from a documented baseline, or your existing firewall audited and brought under management.
- Rule reviews and change controlAn initial clean-up of rules nobody can explain, then every change requested, reviewed, applied and logged.
- Firmware and security updatesVendor updates and security advisories applied in agreed maintenance windows, with a rollback plan.
- Intrusion prevention, web filtering and geo-blockingIPS/IDS signatures kept current, web categories filtered by policy, and traffic from countries you do not work with blocked.
- VPN and zero-trust remote accessRemote staff connected through the firewall's VPN or a zero-trust network access service, with MFA, instead of ports opened to the internet.
- Network segmentationGuest Wi-Fi, cameras, IoT, printers and payment terminals on separate networks, so a compromise in one cannot reach the rest.
- Logging, alerting, failover and documentationFirewall logs and health into our monitoring platform, internet failover configured and tested, and a current network diagram.
How It Works
Delivered through managed IT
The firewall reports health and traffic statistics into NinjaOne, our enterprise management platform, over SNMP alongside your switches and access points, while configuration and policy are managed through the firewall vendor's own console. Changes are made by our engineers under change control and documented in the same system as the rest of your network.

Common Questions
Questions we get asked
How is a managed firewall priced?
A flat monthly fee per firewall, month to month, quoted before any commitment. It covers monitoring, rule reviews, change control, updates, VPN administration and documentation. If we supply the hardware, it is quoted separately along with the security subscription the vendor requires for intrusion prevention and web filtering; if you own a suitable firewall already, there is no hardware cost. A network redesign or a segmentation project is scoped as a project first.
We already have a firewall. Do we have to replace it?
Usually not. If it is a business-grade unit from a vendor still issuing firmware and security updates, we take it over: audit the configuration, clean up the rules, update it and bring its logs into monitoring. We recommend replacement when the model is end of life, when the vendor has stopped updating it, or when it cannot do what you need, such as segmentation or a modern VPN. You get the reasoning in writing, and the decision is yours.
Does this include the router our internet provider gave us?
Carrier-supplied routers are built to deliver the connection, not to protect a business network, and they rarely offer intrusion prevention, segmentation or proper logging. We typically put a managed firewall behind the carrier's device, set the carrier's device to pass traffic straight through, and treat the firewall as the edge of your network. If the carrier's device is doing something it should not, such as running your Wi-Fi, we sort that out as part of setup.
What is network segmentation, and do we need it?
It is splitting one flat network into several, so that guests, security cameras, smart devices, printers and payment terminals sit apart from the computers and servers that hold your data. Most small-business networks are flat, which means a compromised camera or a guest's infected laptop can reach everything. PCI DSS expects segmentation around card systems, cyber insurers ask about it, and it is the single change that most limits how far an intrusion can spread.
Do we still need a firewall if everything is in the cloud?
If people sit in an office, yes. The firewall is what stands between every device in the building and the internet, filters what they reach, isolates the guest and device networks, and gives remote staff a secure way in. Being in the cloud changes what the firewall protects — less a server, more the laptops, phones and printers — not whether something should be doing the job. What changes is sizing: a cloud-first office needs a smaller firewall and a better internet connection.
