Cryptosense Software Suite

Conventional vulnerability management
software checks a list of known attacks.

Cryptosense software imitates an
intelligent attacker to find and prevent
attacks on your specific installation.

Cryptosense Analyzer is the core software offering of Cryptosense. The Analyzer works by using a combination of a patent-pending symbolic machine learning algorithm and a custom developed model-checker. It learns a model of an HSM, Smartcard or software crypto interface under test, creates a model of the device in memory, and searches the model for flaws. Attacks found include cryptanalytic attacks, logical key management policy flaws, implementation errors, and combinations of these. All vulnerabilities found in the model can be tested directly on the device, eliminating false positives.

The full Cryptosense software package also includes Cryptosense MonitorCryptosense App Tracer and Cryptosense Simulator.
