Firewall and network security

Small businesses, churches, and nonprofits are targeted every day — not because they’re famous, but because attackers expect weaker defenses. Most breaches start with something simple: a stolen password, a phishing email, an open port, or a firewall nobody has looked at in years. We focus on practical, affordable protection that closes the gaps that matter most.

Firewall diagnosis & hardening

Your firewall is your network’s front door. We specialize in the leading open-source firewall and router platforms — pfSense, OPNsense, and OpenWrt — and can diagnose problems, tighten security, and get them running the way they should.

Troubleshooting & diagnosis

  • Connectivity problems — devices that can’t reach the internet, each other, or specific sites
  • Port forwarding and NAT issues — cameras, servers, and phone systems that won’t connect from outside
  • VPN problems — WireGuard, OpenVPN, and IPsec tunnels that won’t connect, keep dropping, or run slowly
  • Slow or unstable internet — throughput, packet loss, bufferbloat, and traffic-shaping (QoS/SQM) tuning
  • Multi-WAN and failover — backup internet connections that actually take over when the main line goes down
  • DNS and DHCP issues — Unbound, dnsmasq, and address conflicts
  • VoIP problems — one-way audio, dropped calls, and SIP connection issues caused by firewall settings

Security review & hardening

  • Rule audit — find and remove overly permissive, outdated, or conflicting firewall rules
  • Exposed services check — identify ports and admin pages open to the internet that shouldn’t be
  • Network segmentation — separate VLANs for staff, guests, cameras, phones, smart devices, and payment systems
  • Intrusion detection and prevention — Suricata or Snort with tuned rule sets on pfSense and OPNsense
  • DNS filtering — block malware, phishing, and ad domains for the whole network
  • Secure remote access — replace risky port forwards with properly configured VPNs
  • Admin access lockdown — strong credentials, limited management access, and secure remote administration
  • Updates and backups — firmware and package updates, plus saved configuration backups for fast recovery

Not sure who set it up?

We take over inherited firewalls all the time. We’ll document what’s there, fix what’s broken, and leave you with a clean, well-documented configuration — or help you migrate between pfSense, OPNsense, OpenWrt, and UniFi when another platform is a better fit.

Protecting your people & data

  • Multi-factor authentication (MFA) rollout for email, banking, and cloud services
  • Password manager deployment so every account has a strong, unique password
  • Email security — SPF, DKIM, and DMARC to stop spoofing and improve deliverability, plus phishing filtering
  • Security awareness training — short, practical sessions that teach staff to spot phishing and scams
  • Endpoint protection — managed antivirus and device security for computers and servers
  • Backups that work — the 3-2-1 approach with regular restore testing, so ransomware can’t hold you hostage

Risk reviews & incident response

  • Security assessment — a plain-English report of your biggest risks and what to fix first
  • Account and access review — remove former employees and unnecessary admin rights
  • Policies made simple — acceptable use, password, and incident response guidelines sized for small organizations
  • Incident response — fast help containing and recovering from a compromised account, malware, or ransomware event

Who it’s for

  • Businesses running pfSense, OPNsense, or OpenWrt that need an expert to troubleshoot or review them
  • Organizations with a firewall someone else set up — and nobody knows how it works
  • Churches and nonprofits handling donor, member, and payment information
  • Businesses with cyber-insurance requirements like MFA, backups, and security training
  • Anyone who has had a “close call” with a phishing email or hacked account
