Hi there! I’m Davide Cioccia, founder of DCODX, an ethical hacking, and DevSecOps consulting and coaching firm. Besides helping companies implement their Sec in DevOps, I’m also a developer of security tools (check our GitHub), OWASP Mobile Security Testing Guide contributor and DevSecCon Chapter Lead for the Netherlands. You can find my talks at security conferences like BlackHat, OWASP AppSec, DevSecCon, DevDays Europe and more online, together with some CVE disclosed to Microsoft and other big vendors. Enjoy my course :)
