About the Sentinel SL Platform

Sentinel SL is a virtual protection key that is installed and stored on the end-user's device. Based on the Sentinel HASP HL protection technology, Sentinel HASP SL provides the strongest software-based security available. Sentinel HASP SL protects software copyrights and Intellectual Property and offers a variety of flexible licensing options while enabling Electronic Software Distribution (ESD) to reduce time to market and operational costs.

Product Activation with Sentinel SL

When software-based Product Activation is chosen, the software is activated and can be used only after an internet transaction is performed. The end user electronically transmits a unique Product Key supplied by the software vendor, to a remote Sentinel LDK EMS Server and a Sentinel SL protection key containing license terms is sent back and installed on the end-user's PC-activating the software. The Sentinel EMS API included with Sentinel LDK enables integration with your backend systems such as ERP or CRM.
