Ferret OSINT

Ferret OSINT brings essential open-source intelligence tools to iPhone for fast, focused technical investigation. Built for mobile workflows, it helps you analyze public domain and footprint data without unnecessary complexity.

Your results stay under your control. Ferret OSINT stores all data locally on your device with AES-256 encryption, avoids third-party storage, and uses open, transparent methods based on publicly available sources.

Core features:

DNS Lookup — Review DNS records grouped for faster analysis of domain infrastructure.
WHOIS — Check public registration details, registrar information, and key domain dates where available.
Subdomain Discovery — Identify related subdomains to expand visibility into a target's public-facing surface.
Public Email Discovery — Find publicly exposed email addresses from open sources using non-intrusive methods.
Shodan Integration — Export subdomain results directly to Shodan. Select multiple targets and send them as a batch for deeper infrastructure analysis.
