Self-Hosted Exposure Scanner
Build a SaaS plus lightweight local agent that scans self-hosted services, detects public exposure, weak authentication, and risky container publishing, then explains the findings in plain language. The strongest value is helping non-experts answer a simple question: what is reachable right now, why is it risky, and how do I fix it safely.
Pourquoi c'est important
You expose one app for convenience, assume it is harmless, and only realize later that the interface could trigger dangerous actions or had no meaningful access control. Even if you use containers, you are not sure whether the service is truly isolated, whether Docker published a port you forgot about, or whether your firewall behaves the way you think it does. The hardest part is not reading another security guide. It is getting a clear answer about what is publicly reachable today and what to change first without breaking your stack.
- · Conçu pour Individuals and small home-lab operators who run Docker-based media, download, and utility apps and want to know whether anything is accidentally exposed..
- · Monétisation la plus probable : SaaS subscription.

Périmètre MVP · 1–2 semaines
- Build a local agent that enumerates Docker containers and published ports
- Create an external reachability check service to test whether declared ports are public
- Design a simple severity model for missing auth, open admin UIs, and dangerous defaults
- Ship a basic dashboard with asset list and risk scores
- Write first remediation playbooks for common torrent and media web apps
- Add reverse-proxy detection for common Caddy and Nginx patterns
- Implement alerts for probable UPnP or silent public exposure conditions
- Create plain-language fix instructions with copy-paste config examples
- Launch a free scan page with email capture and local-agent download
- Run onboarding tests with 10 target users and refine false-positive handling
Différenciation
Pourquoi cela pourrait échouer
Auto-contre-argument — le signal de confiance le plus important
- 1Users may prefer free scripts and open-source scanners over a paid monitoring layer
- 2False positives or incomplete detection could quickly erode trust in the product
- 3The audience may be large enough for a tool business but too price-sensitive for strong retention
Résumé des preuves
Comment l'IA a synthétisé cet aperçu — pas de citations textuelles
This opportunity is supported by the most frequent and highest-intensity pain cluster. Roughly 18 mentions focused on accidentally exposed admin interfaces, another 16 on confusion about safe exposure and networking basics, and 8 more on defaults that silently publish services. Multiple participants also expressed uncertainty about whether their containerized apps were actually safe, indicating strong demand for verification rather than generic education.
