Cost reality

Software free; console/cloud features may be paid—verify pricing.

Pricing and free-tier limits change frequently; re-check official pricing before budget decisions.

Official pricing

Tasks reduced or augmented

Software does not replace community or ops staff. It may reduce or augment:

Brute-force mitigation
Log-based detection

Human oversight still needed

False positives
Signal sharing preferences

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

Workflows: incident-response, compliance-review

Problems: privacy-compliance, secure-door-access

Smallest useful experiment

Protect the reverse proxy in front of admin logins and review false positives for a week.

Typical time to first value: 1–3 days
