Jacob KrellCybersecurity Expert
I'm an offensive security specialist with a passion for breaking things to help organizations build them back stronger. My expertise spans penetration testing across web applications, networks, wireless infrastructure, and physical environments, complemented by red team operations, social engineering campaigns, and purple team assessments. I also provide Android forensics services for mobile device investigations and evidence analysis. What sets me apart is my ability to think like an attacker while understanding business risk—I don't just find vulnerabilities, I help you prioritize and fix them.
With credentials including OSCE3, OSCP, OSEP, OSWE, and 20+ other elite certifications, I've spent years honing my craft through real-world engagements and competitive hacking. As a Top 50 global Hack The Box player with over 350 machines completed, I stay sharp by continuously challenging myself against the latest attack techniques and defensive technologies. This hands-on experience translates directly into more thorough, realistic assessments for my clients.
Beyond technical testing, I provide virtual CISO services that bridge the gap between offensive security findings and executive decision-making. I help organizations build comprehensive security programs, navigate compliance requirements, and develop strategic roadmaps that align security investments with business objectives. Whether you need penetration testing, red team operations, social engineering assessments, purple team exercises, Android forensics, or ongoing security leadership, I deliver practical solutions grounded in real-world offensive security expertise.
