About the founder

With over 25 years in the cybersecurity trenches, I've had the privilege of protecting some of the world's most dynamic platforms and 3 of the top European Unicorns and Decacorns 🦄 (Skype, Skyscanner, and Miro).
My journey spans both offensive security and building enterprise defense programs. Most recently, as Head of Product Security at Miro, I led security initiatives safeguarding millions of users' collaborative work across Application Security, Cloud Security, and Detection & Response. Previously, I served as CISO at Skyscanner and Principal Program Manager at Microsoft and Skype where I helped secure platforms serving hundreds of millions of users
My hands-on technical background includes developing open source security tools that are still actively used by the community, as well as creating custom automation solutions that enhance security efficiency.
I founded Ascensis to bring this enterprise security expertise to growing companies in a practical, business-aligned approach that scales with your growth journey. I regularly share insights on cybersecurity trends and best practices through my newsletter Security and Innovation Notes.
