Hi, my name is Grant, and I'm currently the Founder of DarkHorse Security - where we're democratizing access to proactive cybersecurity. I've been in information security / application security for over 13 years (and spent the last ten years leading service delivery at Bugcrowd), and I'm on a mission to make cybersecurity essentials accessible and affordable for organizations of all sizes and budgets - including yours! We believe that far too many organizations aren't able to do enough on the security side of things due to existing solutions being expensive and often unaffordable - which consequently puts their organizations (and your data) at risk. Breaches are expensive; DarkHorse isn't. We're making proactive security affordable and accessible for everyone across five product lines: Application security assessments Penetration testing Fractional pentesting Bug bounties Vulnerability dislcosure programs If you'd like to learn more about what we're doing, please visit the DarkHorse site at darkhorse.sh.

All I have to say is this: Who else has managed to nab 2 industry certifications, one of which is so hands-on and practical it puts even the OSCP to shame in terms of the sheer number of flags, subnets, and live machines, while still in a community college, and is on track to have no less than 5 certifications in the bag prior to transferring? I'm guessing no one.
