About this extension
PRISM OSINT lets you run open-source intelligence scans without leaving your browser.

Select a domain, IP, email, phone, or username on any page, right-click, and pick "Scan with PRISM" — or open the popup and type a target. The scan runs against your own PRISM instance and the results appear right inside the popup: a live progress log, an OPSEC exposure score, findings, and per-module details (DNS, WHOIS, subdomains, open ports, breaches, and more).

Point it at your self-hosted PRISM for full privacy, or use the public demo to try it. No account, no telemetry — the extension only ever contacts the server you configure. Available in 9 languages.
