Self-Hosted Security Auditor
A SaaS or local-first web app that scans a self-hosted stack and explains actual internet exposure, risky Docker defaults, weak proxy settings, and missing hardening steps. It turns scattered forum advice into a prioritized action plan tailored to beginners.
Why this matters
You have several security pieces in place, but you still do not know whether the whole setup is safe or just looks safe. The hard part is not installing a proxy, login gate, or SSL certificate. It is understanding how Docker networking, forwarded ports, proxy routes, and authentication rules combine in practice. You worry that a single hidden default could expose a service you thought was protected. Generic hardening lists are overwhelming, and advanced networking advice often assumes deeper experience than you have. What you want is a clear answer: what is exposed, what is risky, and what should be fixed first without turning your server into a full-time project.
- · Built for Beginner to intermediate self-hosters running Dockerized apps behind a reverse proxy who want confidence before exposing services to the internet..
- · Most likely monetization: SaaS subscription.

Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Users may see this as a one-time setup tool and resist recurring payment
- 2Accurate detection across many custom setups may be harder than expected
- 3If the product misses a serious issue once, trust and word-of-mouth could collapse
Evidence Summary
How AI synthesized this insight — no verbatim quotes
The discussion showed repeated uncertainty about whether an exposed Docker stack was genuinely secure even when protected by a proxy, auth layer, and HTTPS. Mentions around baseline safety, actual exposure, and Docker firewall surprises appeared frequently across both batches. Users also asked for practical next steps rather than theory, which supports a product that audits current state and translates findings into prioritized actions.
