Sentinel HL Max - Micro Form Factor

Flexible Licensing with a sleek design

Sentinel HL Max (Micro)Sentinel HL Max offers a robust protection and flexible licensing enforcement in a sleek new design – making it virtually invisible and decreasing the possibility of accidental or deliberate damage.

The ideal solution for cases in which reduced visibility minimizes the likelihood of tampering and accidental or deliberate breakage, including use with notebooks, embedded systems, medical devices, machinery controls and other equipment with stationary licensing keys.
