The product
One side panel for the next security check.
Start with what is in front of you. Coeus helps you inspect it locally, find other indicators on the page, and follow the sources you trust.

A clear path from question to source.
Inspect what you found.
Bring selected text or an image into a local tool. Decode an encoded command, read an email header, inspect a QR code or extract indicators without leaving the page.
Scan when you need context.
Ask Coeus to check a bounded snapshot of the visible page. Its scan list groups recognised indicators and images; choose one to see its details. Page marks help you find it again.
Follow your own sources.
A domain, IP, hash or other recognised value opens in focused detail first. Choose one source or open the enabled matches together in a browser tab group.
Make it yours
The right sources are the ones you use.
Enable the destinations that matter to you. Each source can support different indicator types, and you can turn off a type for one source without losing the rest. Add your own source by showing Coeus a search you already make, then test and confirm its URL before saving it.
