A network your business
can rely on
Network problems kill productivity and create security risks. W3IT designs, configures and manages business networks that are fast, segmented, secure and supported — with proactive monitoring so issues are caught before they affect your team.
We manage our own network using the same standards we apply to clients. VLAN segmentation, DNS filtering, MFA-protected VPN and firewall rules aligned with the principle of least privilege — all running on commodity hardware most SMEs already own.
Most SME networks are a flat, unsegmented risk
The default network configuration from an ISP router creates a flat network where every device can see every other device. That's convenient — and dangerous.
- One infected device reaches everything In a flat network, ransomware on a staff laptop can spread to file servers, point-of-sale systems and network printers without crossing any security boundary.
- Guest Wi-Fi on the same network Visitors, contractors and personal devices on the same network as your business systems create both security and compliance risks.
- Remote access not properly secured VPN or RDP exposed directly to the internet without MFA or IP restrictions is one of the most common SME breach entry points.
- No visibility of network activity Without logging, you have no way to know if a device is behaving abnormally — communicating with unusual addresses or generating unusual traffic volumes.
Network support from edge to endpoint
We manage every layer of your network — from the internet connection to the device on the desk.
Firewall Configuration & Management
Firewall rule audit and hardening, inbound rule minimisation, geo-blocking of high-risk regions, intrusion detection configuration and regular rule reviews. We work with enterprise-grade firewalls on SME budgets including pfSense, Sophos and Cisco Meraki.
Network Segmentation (VLANs)
VLAN design and implementation to separate staff devices, guest Wi-Fi, IoT/smart devices and servers. Segmentation limits blast radius — a compromised device on the guest VLAN can't reach your file server on the management VLAN.
Wi-Fi Design & Deployment
Access point placement for full coverage, WPA3 configuration, SSID management with separate networks for staff, IoT and guests, and roaming configuration for multi-floor offices. We size and specify hardware correctly from the start.
VPN & Remote Access
Site-to-site and remote-access VPN configuration with MFA enforcement, split tunnelling design and remote access policy. For businesses moving to zero-trust models, we implement Cloudflare Access or similar solutions as a VPN replacement.
Monitoring & Incident Response
Network traffic monitoring, syslog collection, anomaly alerting and incident response for network-level events. If a device starts generating unusual traffic at 3am, we're alerted and can investigate before your staff arrive in the morning.
What we commit to
No Unnecessary Hardware
We work with what you have where possible. New hardware is only recommended when your existing equipment genuinely can't support the required configuration.
Same-Day Outage Response
Network outages are treated as emergency incidents. We respond within 1 hour during business hours and escalate to out-of-hours support for critical systems.
Full Network Documentation
We document every configuration change and maintain a current network diagram. You're never locked in — another engineer can pick up where we left off.
Proactive, Not Reactive
Monitoring means we often identify and resolve issues before you notice them. Our goal is for your network to be invisible — reliably working in the background.
