About osin.uz
osin.uz is an open-source intelligence (OSINT) platform for security engineers, sysadmins and site owners. Every module works with public data only: WHOIS, DNS, Certificate Transparency logs, TLS certificates, HTTP headers and open APIs.
What it does not do
- No port scanning, brute force or exploitation — nothing active or intrusive.
- No authentication bypass, no access to private data.
- No plaintext query storage — the client IP is hashed, queries expire.
Rules
Only test assets you own or have written permission to test. You are responsible for how you use the results.
Limits
Up to 120 lookups per hour per IP. Results are cached for 15 minutes.
