# Enhanced Fingerprinting

While our default cookieless tracking already handles most VPN scenarios, some teams need even more advanced capabilities. \
\
For organizations looking to maintain visitor identity across devices, browsers, domains, and network changes - including the most persistent VPN masking - HockeyStack offers an Enhanced Fingerprint option. \
\
This premium add-on, powered by [Fingerprint.com](http://fingerprint.com/), goes beyond standard fingerprinting by using a proprietary identification model designed to handle challenging cases like:

* Visitors who regularly switch between work and personal devices
* Browsers running in strict privacy modes
* High-frequency VPN and proxy users
* Mobile-to-desktop session transitions
* Support for Customers with Multiple Domains

When enabled, Enhanced Fingerprint works seamlessly alongside HockeyStack’s core tracking. No extra scripts or changes to your snippet are required - just enable it with your HockeyStack representative or Customer Success Manager, and the system begins applying the enhanced model to your existing visitor data.\
\
The result is a higher match rate for unique visitors, more accurate deduplication, and improved continuity in your analytics - without compromising on privacy or compliance. \
\
As with our standard fingerprinting, Enhanced Fingerprint never stores IP addresses or PII, and all identifiers are securely hashed before processing.
