Managed Security for Agile teams

I make security testing agile by bringing it inline with your sprints. Not just once a year.


I prevent and identify security defects early to save you time and to reduce rework costs.


I am a team of leading appsec experts, supporting your team. Not the umpteenth tool.


I measure security progress and provide insight to satisfy your stakeholders.

Meet the new security expert on your team

Hi, I am a passionate application security expert with over 100 years of experience.

I have reviewed millions of lines of code in any language. I helped teams to secure thousands of mission critical applications and dealt with the weirdest flaws you can imagine. But, also had the privilege to see tons of beautiful, flawless code too!

All this experience skilled me to recognize security bugs fast and to fix and prevent them efficiently.

It's my passion to support development teams, to continuously guard the security quality of all the things they build and to make them security smarter on the go. So they can focus on shipping great products,
fast, and responsibly!
