Paste an IP, domain, hash, or CVE — the atlas checks every major free feed at once and tells you what they say. No sign-up, no API keys, no install. For students, researchers, and anyone trying to understand what's going on out there.
The free, open security data already exists — CISA KEV, EPSS, MITRE ATT&CK, abuse.ch, Spamhaus, HaveIBeenPwned, NIST, the research datasets. The hard part is using it. Each feed has its own format, its own access pattern, its own quirks. Stitching them together for one question — "what do we know about this indicator?" — is most of the work in a real security investigation.
The Open Cyber Atlas does that stitching, once a day, for everyone:
It's a teaching tool first. Built for students at GWU and anyone else who wants to understand how the open cybersecurity ecosystem fits together. Free, no account, no tracking.
