About Me.

Security Architect & Manager

I am Gabor Lengyel. I have 10+ years of information and application security experience. I have worked in the telco, banking and software development industry. I helped transform security at companies small and big - or started it from scratch and built it to last. I worked as a software developer and have substantial application security experience. I can make security work with agile, secure development with operations (SecOps, DevSecOps), product management with security. I can help you build secure applications the easiest possible.

See my answers and comments on Stack Overflow to get a sense of what I think about security and secure development.

I am the owner of application security services and remote penetration testing company Prodexity.
