Firewall & Network Security

Advanced threat protection, deep packet inspection and robust perimeter defense for your office — enterprise-grade security without the enterprise price tag.

At a Glance
Full Traffic Visibility

Know what every device is doing on your network, in real time.

Segmented Networks

Guests, staff, servers and CCTV isolated — one compromised laptop can't reach everything.

Intrusion Prevention

Known attack patterns blocked automatically at the perimeter.

Overview

Why It Matters

Your router from the ISP is not a security strategy. We deploy proper next-generation firewalls with intrusion prevention, content filtering and segmented networks — so guests can't see your servers, malware can't phone home, and you can finally see what's actually moving through your network.

Like everything we do at V12, this comes with our family-run promise: honest advice, transparent pricing, and zero-jargon support from the same engineers who built your system.

Scope

What's Included

  • Next-gen firewall deployment — OPNsense/pfSense or commercial NGFW, sized to your line speed
  • Network segmentation — VLANs separating staff, guests, servers, VoIP and IoT
  • Intrusion detection & prevention — signatures updated daily, alerts that reach a human
  • Content & DNS filtering — malware domains and time-wasting categories blocked at the edge
  • Secure Wi-Fi design — enterprise authentication, not one shared password on a sticky note
  • Monthly security reporting — what was blocked, what tried, what changed
Capabilities

What We Deliver

Next-Gen Firewalls

Stateful inspection, application awareness and geo-blocking at wire speed.

Deep Packet Inspection

Threats hiding inside encrypted and normal-looking traffic get found and dropped.

VLAN Segmentation

Blast-radius control: a breach in one zone stays in that zone.

DNS & Web Filtering

Phishing and malware domains dead on arrival; acceptable-use policies enforced.

Enterprise Wi-Fi Security

WPA3-Enterprise with per-user credentials and rogue-AP detection.

Logging & Reporting

Centralised logs with retention — for troubleshooting, audits and insurance questionnaires.

Our Process

How We Work

01
Assess

We scan and map your current network, finding open ports, flat topology and quiet risks.

02
Design

A segmented architecture and rule policy is drawn up — strict where it matters, invisible to daily work.

03
Deploy

Firewalls and switches configured and cut over after-hours with tested rollback.

04
Watch

IPS signatures update daily; we review alerts and send you a monthly plain-English report.

FAQ

Common Questions

No — modern firewalls inspect at full line rate, and good rule design is invisible to legitimate work. Staff notice exactly one change: the guest Wi-Fi finally works properly and the network feels faster, because junk traffic is gone.

Small businesses are the preferred target — attackers know the defenses are weaker and the data is still valuable. Most attacks are automated scans that hit every IP on the internet; they don't check your company size first.

Usually, yes. We audit what you have — many switches and access points can be reused in a segmented design. We only recommend replacing hardware that genuinely can't do the job.
