Cost reality
Software free; appliance hardware and HA designs cost money. Business support available from vendors.
Pricing and free-tier limits change frequently; re-check official pricing before budget decisions.
Tasks reduced or augmented
Software does not replace community or ops staff. It may reduce or augment:
- Edge firewall
- VPN concentrator
- Captive portal experiments
Human oversight still needed
- High blast radius misconfig
- Change control
- HA complexity
Data held
-
firewall logs
-
DHCP leases
-

Risks
| Area | Notes |
|---|---|
| Vendor lock-in | Evaluate export formats and API completeness before deep customization. |
| Security | Apply updates promptly; restrict admin access; enable TLS. |
| Compliance | Operator remains responsible for privacy and local regulatory obligations. |
| Licensing | Confirm license fits commercial coworking use. |
| Operational | Plan backups, monitoring, and a restore drill before production use. |
Coworking fit
Roles: technical-operator, facilities
Workflows: facility-maintenance, incident-response, visitor-management
Problems: improve-wifi-reliability, secure-door-access, privacy-compliance
Smallest useful experiment
Lab install as a VM firewall in front of a test VLAN before touching production internet edge.
Typical time to first value: 1–3 days
