Zertificon stands for securing digital business. We develop trusted IT security solutions "Made in Germany" – built for businesses that value both protection and usability.
- Independent & committed: For over 20 years, we’ve built secure communication tools – as an owner-managed company with a clear stance
- Purpose-driven: We believe that digital communication must be secure and free. If you think Edward Snowden did the right thing as a whistleblower, we might just share the same values. As a sign of our support, we donate €1,000 to an organization that supports Edward Snowden for every new hire who mentions him in their application
- Hands-on excellence: We take on complex challenges because we can. Our in-house experts are top-tier – even external specialists often learn from us. When we want the best, we build it ourselves
- Agile by conviction: We think fast, act pragmatically, and improve continuously. No bloated processes, no “that’s just how it’s always been done.” Initiative is welcome – but of course, it will be challenged, and not every idea will make it through unchallenged
- Security that works: We build software that’s not only secure, but actually usable – not just for large enterprises with dedicated highly skilled IT teams, but also for small and mid-sized businesses that need strong security without the complexity
- Diverse & international: Our team of 130 people from 30+ countries shares one mission: making secure digital communication easily accessible to businesses of all sizes
If that resonates with you, we’d love to hear from you.
