Network Segmentation Is Not Optional
A flat network where every device can reach every other device is a security disaster waiting to happen. One compromised device — a printer, an IP camera, a guest laptop — can reach your accounting system, your server, everything.
Proper segmentation using VLANs puts your critical systems on separate network segments with controlled access between them. A compromised guest network device can't even see your business network.
Firewall Design Matters
A consumer-grade router-firewall is not adequate for business use. A proper business firewall provides:
- Application-layer inspection — understanding what traffic is doing, not just where it's going
- Outbound traffic filtering — blocking exfiltration attempts
- IDS/IPS — detecting attack patterns in real time
- Logging that's actually useful for incident investigation
The Value of Network Monitoring
You can't defend what you can't see. Basic network monitoring tells you when devices communicate outside their normal patterns — often the first sign of a compromise. For small businesses, a simple SIEM or even well-configured firewall logging provides tremendous value.
We regularly find that our small business clients have compromised devices on their networks that have been there for months — never detected because nothing was monitoring for unusual behavior.
