Network security, firewalls and business Wi-Fi
Next-generation firewall configuration, VLAN segmentation and enterprise wireless — designed, reviewed regularly, and documented.
Almost every business network we look at was configured correctly on the day it was installed. The problem is what happened afterwards. A temporary rule opened for a supplier three years ago and never closed. A guest Wi-Fi network that quietly sits on the same VLAN as the accounts system. A camera system plugged into whatever port was free. None of it was a mistake at the time; all of it accumulates.
Network security is not a product you buy once. It is a configuration that has to be reviewed, because the business changes around it. We design, configure and actively manage next-generation firewalls and business wireless, and — the part that actually matters — we review the ruleset on a schedule and document what is there and why.
We are vendor-neutral by choice. The right firewall for a single-site office of fifteen people is not the right firewall for a manufacturer with three sites and a warehouse full of scanners, and we would rather specify for the situation than for a partner agreement.
What's included
What network security covers
Next-generation firewall configuration
Specified, deployed and configured for your actual traffic, not a default template.
Firewall rule review and hardening
Scheduled review of what each rule is for and whether it is still needed.
Network segmentation and VLAN design
Separating the systems that matter from the ones that merely need internet.
Business and guest wireless
Enterprise wireless designed for coverage and access control, with guest traffic properly isolated.
IoT and operational technology isolation
Cameras, sensors, printers and machine controllers kept off the network your data lives on.
Intrusion detection and prevention
IDS/IPS enabled and tuned, so it produces signal instead of being switched off in frustration.
Remote access and VPN
Secure remote connectivity with MFA, replacing whatever was stood up in a hurry.
Multi-site connectivity
Site-to-site links designed so a second location does not double your attack surface.
This is probably for you if
- Nobody has reviewed the firewall rules in over twelve months
- Guest Wi-Fi and business systems share the same network
- Cameras, printers or machine controllers sit on the main network
- Nobody can produce a diagram or document of how the network is arranged
- Remote access was set up quickly during a crisis and never revisited

Network work across St Helens, Liverpool and Warrington
Network security is the part of this job that genuinely benefits from being local. Surveys, installations, switch and access point work, and fault-finding all need somebody on site — and being based in St Helens puts Liverpool, Warrington, Wigan, Widnes and most of Merseyside within a short drive.
A lot of our regional work is in older industrial and converted buildings, which have their own character: thick walls that defeat consumer access points, historic cabling of uncertain provenance, and production equipment that cannot simply be taken offline for an afternoon. Planning around that is part of the work rather than an obstacle to it.
Common questions
At least annually as a floor, and after any significant change — a new site, a new line-of-business application, a supplier integration, or anyone leaving who had remote access. The risk is rarely one dramatic misconfiguration; it is accumulation, where each individually reasonable rule adds up to a perimeter nobody fully understands.
Because a guest device is unmanaged by definition. You do not know its patch level, what is installed on it, or whether it is already compromised. If it lands on the same network as your file server, you have extended trust to a machine you have never seen. Proper isolation gives guests internet access and nothing else.
We are deliberately vendor-neutral and specify against the requirement — site count, throughput, remote access needs, and what you already own. We are happy to work with equipment you have already invested in where it is fit for purpose, rather than replacing it for the sake of it.
Yes, and it is a common arrangement. Network and security work is a specialism that many general IT support providers do not cover in depth. We can take the network layer while your existing provider continues with day-to-day support.
Yes. For anything involving wireless coverage or a building we have not seen, a survey comes first. Designing wireless from a floor plan alone is guesswork, particularly in industrial buildings.
