Strong Authentication

We understand the importance of strong authentication in safeguarding your sensitive information and systems. Our team helps you in choosing the right authentication solution depending on threats and prerequisites, integrating it in custom applications, and rolling it out on a large scale. We are well-versed in the latest authentication standards such as FIDO2, passkeys, and passwordless login but also know One-Time Passwords (OTP, TOTP, HOTP) in and out, enabling us to deliver cost-effective solutions that meet the required security level.

Public Key Infrastructure (PKI) and Hardware Security Modules (HSM)

We support you in setting up a PKI and integrating Nitrokey HSM or NetHSM. This includes requirements analysis, high-level solution design, policy development, key ceremony, technical integration of HSMs into custom applications, and usage of HSMs to secure your crucial cryptographic keys during their entire life cycle.


We specialize in security hardware, embedded Rust development, IoT, low-level and full-stack security development. Our expertise in these areas enables us to deliver innovative and secure solutions that protect your digital assets from the ground up. Whether you want to build secure hardware or software applications with minimal attack surface, we have the skills and experience to get the job done right. Our developer team is passionate and experienced in Rust but has many years experience in Python, C and C++ as well. As one of the driving developers behind the Trussed framework we can not just build modern cryptographic firmware in Rust but also extend the framework if needed for your solution. Of course, we are always glad to customize our own hardware products to your needs.
