What We Do

Cryptographic Data Security

Cryptographic Data Security

We can advise you on the data security architecture of your system or we can develop a security design for your project. Our mantra is 'fit for purpose' because perfect security is impossible and overdoing it is just an unnecessary overhead.
Cryptographic Components

Cryptographic Components

We supply and develop cryptographic components in different form factors such as Java smart cards, secure elements, USB/Bluetooth tokens and HSMs. These devices can be used in a range of applications from electronic payments to IoT.



We provide a cloud hybrid security system where you can do your transaction processing in the cloud. You can use your own data centre or interact with securely authenticated HSMs operating in our data centre. The HSMs are accessed over a bilateral TLS session using a REST API.
