VPS-to-Homelab Security Auditor
Build a SaaS or self-hosted agent that inspects a user's VPS, tunnel, and firewall posture to identify whether public services can become a bridge into private systems. The product would translate expert hardening advice into a clear risk score, remediation steps, and optional safe automation.
これが重要な理由
You have a small server in the cloud acting as the doorway to machines at home, and that convenience creates constant anxiety. When you open ports for games or apps, you are no longer just thinking about one server being exposed; you are worrying about whether a compromise could travel through the tunnel into the rest of your environment. Existing tools help with one layer at a time, but they do not tell you whether the overall design is safe. You end up piecing together firewall rules, tunnel settings, and isolation ideas from scattered advice, never fully sure if you have closed the real risk.

- Define the first three supported patterns: VPS relay, VPS plus WireGuard, and public game ports on same host
- Build a lightweight Linux agent that collects SSH, firewall, open-port, and routing metadata
- Create a rules engine for common findings such as public SSH exposure and weak forwarding scope
- Design a simple dashboard with risk score and remediation list
- Write onboarding docs for one VPS provider and Ubuntu only
- Add blast-radius checks for whether the tunnel exposes private subnets beyond intended targets
- Generate exact remediation snippets for UFW and iptables
- Add recurring scans and alerting for newly opened ports or changed routes
- Implement a secure token-based agent registration flow
- Launch a landing page with a self-audit waitlist and demo report

失敗する可能性がある理由
自己反論 — 最も重要な信頼のシグナル
- 1The target users may be too technical and prefer free guides or manual scripts instead of paying monthly.
- 2Security credibility is hard to earn, and any mistaken recommendation could damage trust immediately.
- 3The environment diversity across providers, kernels, and firewall tools may make accurate audits harder than expected.
エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
The discussion repeatedly centered on the danger of combining public services and a private tunnel on one cloud host. Multiple participants proposed manual mitigations such as restricting SSH, narrowing forwarding rules, and splitting workloads, which shows the need is real but current solutions are pieced together. The strongest signal is not just desire for security, but uncertainty about whether the architecture is safe enough.
