David Sopas – Web Security Researcher

About me

and my passion

So you’re checking my About page so I’m guessing I should introduce myself.

Hello! My name is David Sopas and live and work in Portugal.
Many years ago I found out that security was the path that would make me happy and would create opportunities to learn every single day so… I’m a security researcher.

I lead a team of amazing and talented researchers at Checkmarx and at the same time I manage my security company – Char49.

On my spare time, I do professional pentesting for Cobalt specially focusing on Fortune 500 companies.

Part of my work has been already presented in security conferences like Defcon, hack.lu, BSides, OWASP AppSec EU and many others.
Some of the research created a media buzz and were published in Techcrunch, Softpedia, TheRegister, SecurityWeek, ThreatPost, you name it.

I have no plans on writting a book (yet) but some of my work was referenced in three books – Bug Bounty Hunting Essentials: Quick-paced guide to help white-hat hackers, Ethical Hacking and Penetration Testing Guide and Web Hacking 101.

If you want to know more about what I do professionaly just follow my Twitter account.
Also if we have the chance to meet, just approach me and say Hi!

David Sopas
