👋 Hey Product Hunt! I built Knock to solve a problem I kept running into: Codebases, databases, and infra often have serious security issues — and most devs don’t realize it until it’s too late. Knock does three things well: Scans GitHub for hardcoded secrets (AWS keys, DB creds, etc.) Audits Supabase for missing RLS, public tables, and policy gaps Checks your public-facing IPs for exposed ports like RDP, SSH, or admin panels 🛠 You get actionable results: Exact SQL commands to fix RLS issues Real-time alerts when your infra changes Smart suggestions based on actual misconfigurations Most scans take <60 seconds and find critical issues right away. 🔍 If we don’t find anything in 30 days, you get a full refund. Would love your feedback — especially if you're using Supabase in prod or shipping fast and want a second set of (automated) eyes on your stack. Thanks for checking it out! — Sam

Knock sounds like a must-have for modern dev teams. Fast audits with real fixes and a money-back guarantee? That’s confidence—and exactly what security tooling needs more of.
