OSINT investigation tools
Quick answer
An OSINT (open-source intelligence) investigation connects publicly available information about an account, domain, wallet or organization into one picture. Serus is an agentic OSINT tool: start with an email, username, phone number, domain, wallet, screenshot or a plain-language question, and it runs surface, deep and dark web searches in minutes, with every finding linked to its source.

What it finds
- Accounts, domains, wallets and phone numbers connected to what you start with

- Dark web results from sources that include breach dumps, credential collections, forums and market listings, with sensitive values redacted
- Whether scattered indicators (handles, domains, emails, wallets) connect to one actor
- New findings as they surface, from deployed agents that watch names, domains and keywords around the clock

Frequently asked
What is an OSINT investigation?
Research built from open sources: websites, public records, social profiles, breach data and the like. The work is connecting scattered identifiers (an email, a handle, a domain) into one picture you can verify.
What are OSINT tools?
Tools that search and connect open-source information. Many do one job each, like a username search or a breach check. Serus runs the searches together and cross-references the results into one verified profile, instead of scattered pages you connect by hand.
Does Serus search the dark web?
Yes. Dark web scans include breach dumps, credential collections, forums and market listings. Sensitive values like passwords stay redacted until you choose to reveal them.
Can I build Serus into my own systems?
Yes. The developer API lets you start scans, pull results and stream findings as they surface, documented against OpenAPI 3.1.
Is using OSINT legal?
Working with publicly available information is legal in most places, but how you use it is governed by law, including privacy rules like the GDPR and anti-stalking and anti-harassment laws. You're responsible for having a lawful basis for your searches.
