About us

Making secure coding second nature


Just like our bodies need an immune system, our software needs organic protection.

In the age of IoT, corporate digitization and AI, this protection in cyber reality becomes more important with every passing day. Unless all lines of code are developed with security in mind, we risk losing control over our digital future.

And this is the reason Cydrill came to life.


In the human body, defense is woven into each cell — we aim to mimic this system in each line of code, to make programs organically more resistant to attacks. However, creating a built-in “software immune system” requires developers to adopt a radically new mindset.

Enhanced security can be achieved by developing secure coding literacy with a continuous learning journey that is intellectually challenging, emotionally engaging and invaluable in terms of writing secure code.



We help you embed secure coding skills in your organization through a blended learning journey.

Gamified lab exercises assist in the acquisition of best practices so that the coding mistakes that lead to vulnerabilities can be avoided in the future. Secure coding as a discipline implies continuous practice, so we provide a platform for cyber security drills tailored to programmers.


Beyond the code


Live discussion on the context of hacking and the hacker’s mindset fosters a deep motivation to integrate preventative coding practices.


Case studies and lab exercises take developers through the latest high-profile hacks to understand how they could be prevented with secure code


Highly-gamified classroom labs and subsequent follow up e-classroom courses encourage continued practice and retention to close the knowing-doing gap
