We are built on a foundation of trust.

Mission and values

Our success and the future of security depends on the ability for people to build and maintain trust in the systems we are building.
— Arno Fiedler, Founder of Nimbus

We believe in a commitment to transparency and excellent work, and that the core principles of integrity and honesty come before all else in decision-making. The services we provide are based on building this trust between our team members, partners, clients and the world at large, and securing that trust with the most advanced tools available. We have been at this work for the past two decades, bringing about change in the digital environment to make the world a safer place for everyone, from private businesses, governments and extra-governmental agencies to consumers of all ages.
