Traceform is a visitor identification platform for publishers, media companies, and B2B SaaS businesses. Its device fingerprinting technology is designed to recognize returning visitors when cookies are blocked, private browsing is enabled, or IP addresses change through VPN use. By analyzing more than 480 device and browser characteristics, including screen properties, WebGL and canvas rendering, audio processing, fonts, and hardware signals, Traceform creates a persistent device fingerprint and matches visitors across sessions.

The company says its system achieves 99. 5% identification accuracy and can return results in about 50 milliseconds. A lightweight JavaScript SDK supports asynchronous identification without blocking page rendering, and businesses can try a live demo without signing up.

Traceform positions its service as a way for publishers to improve article metering, detect subscription sharing, and reduce paywall leakage, while B2B SaaS teams can identify anonymous prospects, assess engagement, and support account-based marketing. The platform emphasizes privacy controls, including one-way fingerprint hashes, anonymized IP addresses, and configurable data retention
