Sentinel HL Net

Licensing Flexibility in a Networked Infrastructure

Sentinel HL NetSentinel HL Net provides a robust solution for protecting enterprise software designed for operating in a networked environment. By using the Sentinel HL Net key, developers can impose restrictions on the number of concurrent users from a secure program in addition to offer the option of concurrent licensing support.

The most robust yet flexible solution for protecting enterprise software designed for operating in a networked infrastructure while offering the option of adjustable concurrent licensing support.

Note: Network Floating licensing as supported by our existing Sentinel HL Net keys can now be used on all keys (except Basic). This new feature requires a paid upgrade.
