Networks & Firewalls
A business network should be stable, secure and able to grow with you. Neither more complicated than necessary, nor simpler than sensible.
Many SMEs in Galicia still operate networks designed a decade ago that no longer reflect their current reality. A consumer router acting as the firewall, no separate guest WiFi, all devices on a flat network. The result: fragility and unnecessary exposure.
What this service includes
Analysis of the current network. Inventory of devices, cabling, existing configuration, weak points. A clear diagnosis before any changes.
Segmented network design. Logical separation through VLANs: work network, guest network, IoT network (printers, cameras), server network. An attack contained in one segment cannot jump to another.
Next-generation firewall. Deployment of open-source solutions (OPNsense, pfSense) or commercial solutions where you already have them. Clear, documented and auditable rules.
VPN for remote access. Configuration of WireGuard or OpenVPN so your team can work securely from anywhere. Faster and more secure than traditional solutions.
Professional WiFi. Uniform coverage, seamless roaming between access points, separate guest network. Using reliable equipment such as Ubiquiti UniFi or MikroTik.
Network monitoring. Continuous visibility of traffic, detection of anomalous patterns and automatic alerts on suspicious behaviour.
Who is this service for
Offices with more than five employees, businesses with remote workers, shops with connected point-of-sale systems, medical practices and professional firms with confidentiality obligations.
Frequently asked questions
Do I have to replace all my network equipment?
Not necessarily. I assess what you already have first. Existing switches and access points can sometimes be reused. Other times, renewal is worthwhile for energy savings and better manageability.
Do you also install cabling?
I do not install structured cabling directly, but I coordinate with trusted local installers in A Coruña for that part of the project.
What is the difference between a consumer router and a professional firewall?
A consumer router offers basic protection. A professional firewall allows granular rules, deep packet inspection, geolocation blocking, DNS filtering and detailed logs for auditing. For a business with sensitive data, the difference is significant.
Can the network be segmented without interrupting work?
Yes, with proper planning. Critical changes are usually performed outside working hours or at weekends to minimise impact.
