Hey HN, TL;DR: We’ve launched a free version of our Shadow IT scanner to identify which SaaS apps are used in your company, who uses them, and if they have high-risk OAuth scopes. Philip and I went through YC with AccessOwl in 2022. We started the company because, in our previous roles, we struggled to track all the SaaS apps, users, and granted OAuth scopes. The Shadow IT scanner started as a small feature within AccessOwl, which manages SaaS vendors and user accounts centrally.

I built this after seeing multiple teams accidentally ship API keys in their frontend code. The problem: Modern web development moves fast. You're vibe-coding, shipping features, and suddenly your AWS keys are sitting in a tag visible to anyone who opens DevTools. I've personally witnessed this happen to at least 3-4 production apps in the past year alone. KeyLeak Detector runs through your site (headless browser + network interception) and checks for 50+ types of leaked secrets: AWS/Google keys, Stripe tokens, database connection strings, LLM API keys (OpenAI, Claude, etc.), JWT…
