CPU Tech produces the Acalis family of secure processors that protect software and systems from reverse engineering. Acalis enables the development of secure and compatible electronics modernization technology solving obsolescence problems while reducing size, weight and power (SWAP).

The Acalis secure processors directly address the need for anti-tamper (AT) technology in today's critical computing and communications systems while providing a trusted, long-term supply. As the strongest protection available for software and systems, Acalis protects algorithms, rules and data from cloning, malicious insertion and countermeasures.
