Server-side fingerprinting that works across domains. Identity resolution, fraud detection, and behavioral analytics — without cookies.
Cookies are dead
Impressio works without third-party cookies. Server-side signals that browsers can't block.
Fraud is invisible
Real-time bot detection, VPN flagging, and behavioral analysis — built into every request.
Users are anonymous
Identity graphs across domains. Same user on shop1.com and shop2.com? Impressio knows.
Six modules working together — fingerprinting, identity, fraud — all in one API call.
16 server signals (JA4, CloudFront) + 48 client signals (canvas, WebGL, audio) fused into one hash.
Domainprints: identify the same user across different domains via backend resolution. No cookies needed.
Headless browser detection, bot scoring, VPN flagging, rate limiting — integrated, not tacked on.
GDPR-compliant hashing, PII minimization, no raw IPs stored. Privacy is not an afterthought.
One script tag, one API call. Fingerprint + identity + fraud response in under 400ms.
Interactive GeoMap, user timelines, fingerprint browser, fraud charts — no extra cost.
Install a Service Worker on your partner's domain that automatically preserves UTMs, click IDs, and campaign data across the entire user session. Multi-touch attribution with zero data loss — no cookies, no third-party scripts.
