What is Device Fingerprinting?

Device fingerprinting identifies a visitor by the combination of attributes their browser and device expose, rather than by cookies or IP address alone.

How it works

Signals like canvas rendering, installed fonts, timezone, and hardware concurrency combine into a stable identifier that survives proxy rotation.

Why it matters for marketplaces

Fingerprints let you recognize the same operator across thousands of IPs, which is where scrapers and botnets are weakest. For your marketplace, that means your catalog stay protected and buyers and sellers get a fair experience.

How BazaarFort detects it

BazaarFort scores every request against behavioral, network, and device signals, so automated patterns surface even when they imitate real buyers and sellers. Suspicious sessions get challenged or blocked before they reach your marketplace.
