Opsis OSINT Platform
From an identifier to your next investigative lead.
Search emails, usernames and domains across multiple sources. Opsis brings available account signals and public profile details into one report, so you can spend less time repeating lookups and more time evaluating the evidence.
Three starting points. One place to investigate.
Email search
Check for accounts associated with an email address. Review profile information where a source exposes it, and distinguish account-existence signals from identified profiles.
Username search
Look for a handle across supported platforms. Compare source links, names, avatars and other available profile details before connecting accounts to the same person.
Domain search
Add domain context with available WHOIS, DNS and reverse WHOIS checks. Premium domain searches can also extract metadata from accessible public documents.
Built for the analyst’s workflow.
Start with a lead, see what the sources return, and keep your conclusions tied to evidence.
01
Choose your starting point
Enter an email address, username or domain you are authorized to investigate. Choose the search mode that fits your work.
02
Review results as they arrive
Results appear as checks resolve. Inspect the details a source provides instead of treating every match as equally informative.
03
Check the original source
Follow profile links where available, compare identifiers and record what is confirmed versus inferred. A shared username alone is not identity verification.
Useful context for real investigations.
Investigations
Turn an initial identifier into candidate accounts and public context. Compare findings across sources to decide which leads deserve closer review.
Threat intelligence
Research identifiers observed during an incident or in threat reporting. Add public account and domain context to an analyst-led investigation.
Fraud-signal review
Examine public profile details and apparent inconsistencies around a reported account. Use the findings alongside your own evidence—not as a verdict that someone is fraudulent.
Know what a result actually means.
Opsis uses source-specific modules and positive/negative health checks to help identify broken checks and reduce false positives. Some sources provide rich profiles; others answer only whether an account appears to exist. Available fields and coverage vary.
A blocked or timed-out source is not a clean negative. A match is a lead, not proof of identity. Read how we check results or follow the reverse email lookup workflow.
Multi-source searches require a subscription. Standard searches use one credit; premium username searches use two and include additional solver-backed checks. See plans and allowances. Individual free tools and previews are available separately.
