Our passion for Open Source and cryptography brought us to work in security and engineering for numerous companies during the past decades. Find out what we can get done for you.



Let’s take a closer look.

IT without security is unthinkable. No matter where your software runs, be it in a tiny microchip or in some large server cluster: At some point you have to deal with software security. That’s where we come in: Security is and has always been an integral part of our work. So, let’s test your system - we are here to support you!

We love to share our knowledge.

That’s why we provide dedicated in-house workshops on a variety of topics; be it additional to our other offers or as a standalone service. Sure, we do lectures, but mainly as booked speakers. In our experience individually designed workshops are the key to success. Your engineering team lacks some knowledge or skills we can provide? Get in touch!

Time to team up

Some of our customers hire us because they are stuck, others lack the manpower to fulfill their engineering ambitions. Some are looking for a long term security strategy, others need to find that one bug. No matter what the issues are, we try to get to the bottom of it. In our opinion the best way to do this involves getting to know you and your team and work out the best solutions together.
Finding out what really works sometimes leads to unexpected places.
Let’s team up and get things done!
