Discover our compelling case-studies that represent an extensive range of security and safety-critical use-cases.



Securosys is the leading HSM provider for securing assets, identities, and communications with a focus on the banking and blockchain industry.


Securosys is facing a huge demand to execute applications on secure hardware that guarantees integrity and confidentiality of code and data during rest, transit, and runtime.


Proving the integrity and confidentiality of applications during runtime requires strong isolation and proving the trust-graph of all components and their dependencies to a hardware root of trust.


Gapfruit provides a revolutionary platform with the highest security properties on the market. The platform can easily be customized and integrated. Our unique technology enables complete control over all software stacks and allows our customers to form rational arguments about why their product is considered trustworthy. Therefore, it is perfectly suited to build TEE appliances.


Securosys IMUNES is a Trusted Execution Environment for the highest security requirements set in the banking, blockchain, and payment sector. Securosys is a pioneer in providing attestable trustworthiness for its TEEs through the capability-based security engineered at Gapfruit.

A Securosys IMUNES can prove that a certain output was generated from a specific input, executed at a particular time with specific code. The integration is straightforward with an easy-to-use API. Securosys was able to release the product in no-time, thanks to Gapfruit.

An evolutionary approach to provide facilities unavailable in ARINC 653.


Gapfruit is aiming to build a platform where strong security and safety requirements meet.

Please get in contact with us to develop the next generation of interconnected safety-critical systems.


Jim Podmore, a renowned aircraft engineer, shows how Gapfruit addresses a significant limitation of ARINC 653 based RTOS's, which is their static configuration. The ability to reconfigure a system dynamically, albeit in a carefully controlled manner, provides excellent flexibility in a system while limiting individual components' complexity.
