fail2ban

Fail2Ban matters only if the evidence supports a paid workflow around keeping sites trusted, protected, and recoverable, not a list of isolated fixes. The current commercial thesis is: Security, spam, and trust failures create business risk that owners struggle to triage. The entry wedge is to turn security and abuse signals into prioritized actions, audit trails, and recovery-ready reporting.

Opportunity Summary

Full report

Build a trust and abuse-prevention operations plugin for site owners, agencies, and maintenance teams: Security, spam, and trust failures create business risk that owners struggle to triage. The first wedge is to turn security and abuse signals into prioritized actions, audit trails, and recovery-ready reporting.

The unmet need is not the individual complaint. It is the recurring business workflow: Security, spam, and trust failures create business risk that owners struggle to triage. Current stage: commercial plugin opportunity.
