About Cloudyrion

With Us, You Can Make Your Solution Portfolio Fit for the Future

As a start-up with comprehensive expertise in the areas of risk assessment, penetration testing and consulting, we work closely with our clients to ensure that security standards become an integral part of the development of applications and services – within a defined framework and excluding technological missteps.

Our Story

In 2020, Okay Güler founded Cloudyrion with the goal of completely rethinking client partnerships. This includes mentoring and coaching, as well as market analysis, technical support, and brand positioning or application processes.
From the very beginning, our efforts were focused on embedding the secure-by-design approach, which enables companies to create lasting security for their solutions throughout the entire product lifecycle. Demand for these services developed so quickly that we can and want to grow strategically. To ensure that our mission succeeds over the long term, we are continuously looking for new employees.
