Reverse Proxy Bot Shield for Small Sites
Build a SaaS plus lightweight agent that analyzes web server logs, detects spoofed crawler and scan traffic, and automatically generates blocking rules for NGINX, Caddy, and fail2ban. The strongest value is not raw threat data but fast, low-effort enforcement for operators who do not have a security team.
Pourquoi c'est important
You run a site or small app stack and suddenly see bursts of suspicious requests that pretend to be well-known crawlers or AI agents. You know some are vulnerability probes, but proving that and blocking them safely takes time you do not have. Generic CDN protection helps somewhat, yet you still want control at your own reverse proxy before origin resources are wasted. The current path is messy: inspect logs manually, look up ASNs, guess which providers to block, and hope you do not lock out real visitors. A tool that turns raw logs into safe, explainable blocking rules would save hours and reduce anxiety every time a new scan wave appears.
- · Conçu pour Indie hackers, small SaaS teams, self-hosted app operators, and sysadmins running their own reverse proxies who need better bot filtering without enterprise tooling..
- · Monétisation la plus probable : SaaS subscription with usage tiers.

Différenciation
Pourquoi cela pourrait échouer
Auto-contre-argument — le signal de confiance le plus important
- 1Many operators may prefer free community blocklists and occasional manual blocking instead of another subscription.
- 2False positives on VPN, privacy, or shared-network users could create support burden and reputational damage.
- 3Large security vendors may already offer adjacent features, making differentiation difficult unless onboarding is dramatically simpler.
Résumé des preuves
Comment l'IA a synthétisé cet aperçu — pas de citations textuelles
The discussion repeatedly focused on forged user-agents, recent scan surges, and the desire to stop suspicious traffic at the reverse proxy before it reaches origin. Several commenters discussed ASN blocking, log analysis, and the limitations of generic bot checks. Multiple solution mentions show that the need is active, but current workflows remain manual, fragmented, and error-prone.
