Overview Sentinel has been setting the standard for software protection since 1984 and secures more clients worldwide than any other key. SentinelĒ UltraPro keys protect against revenue leakage so vendors receive fair compensation for software development. Use of the AES public algorithm protects against hacking and further defense is provided against driver replacement and debugging tools. UltraPro also thwarts record and playback hacks through the auto-generation of large query tables. Licensing flexibility provided by UltraPro allows vendors to reach new markets, leading to increased revenue. Pre-built license models include feature-based, evaluation and pay-per-use. A range of features, such as Business Layer APIsĒ, speed development time, allowing developers to reduce costs and quickly respond to customer needs.
Features Up to 512 bytes of memory, pseudo-random function, unique serial number for each device, counters and remote algo activation
