Many smaller businesses run every device, from printers to the finance server, on a single network. If one laptop is compromised, an attacker can reach everything. Segmenting the network into zones, with firewall policy controlling traffic between them, contains the damage.
A practical starting design:
- Separate zones for staff, servers, guests and IoT devices
- Allow only the specific flows each zone needs
- Audit and remove unused firewall rules before and after the change
