Stop multi-accounting and fraud with device fingerprinting

Repeat Sign-Ups
Prevent the same users from creating multiple accounts.

Account Sharing

See when an account is being used by different devices.
Account Takeover
Identify anomalies or spoofed device fingerprints.

More than just a device ID

Catch users across incognito & browsers
We use multiple layers of device, browse, and TCP features that let us match users across browsers - something no one else can do.
Take a multi-fingerprint approach
We create multiple fingerprints and match users probabilistically, instead of using a single binary device ID. This means more accurate links without the false positives.
Catch anti-detect browsers
Spoof- and lie-detection technology validates that the data coming from the device is ground truth, so we can catch anti-detect browsers that trick other providers.

"After finding Verisoul and integrating with them for less than a day, we had access to insights that would have taken us months to build. With Verisoul we get higher quality signups, and a design partner in helping us catch the latest trends in fraudulent usage. "

Read how Splitdrop reduced fraud by 82% with Verisoul's Fingerprinting

“After seeing our fraud rates drop by 82% in the first month of using Verisoul, I asked them to set up a referral program, because it's so powerful.

We were able to get rid of other vendors with high false positive rates when we switched to Verisoul.”
