Ben Rollin (mrb3n)
Founder, Vilkas Cybersecurity
Ben Rollin is the founder of Vilkas Cybersecurity and has nearly 20 years of experience in penetration testing, web application security, and technical risk assessment across enterprise and government environments. Over his career, he has performed hundreds of assessments, consistently uncovering complex attack paths that have often existed undetected for years.
His work is heavily focused on Active Directory and identity-based attacks, where small misconfigurations can lead to full domain compromise. Ben is known for digging deep into environments, identifying how issues chain together, and demonstrating real-world impact beyond isolated findings.
A Big Four–trained consultant with certifications including CISSP, OSCE, and OSCP, Ben also develops hands-on training and technical content for security professionals. He regularly teaches and writes about penetration testing, Active Directory security, and practical ways organizations can reduce risk.
He places strong emphasis on getting the fundamentals right. Many of the most impactful findings stem from basic misconfigurations, not advanced exploits. His approach focuses on understanding how systems actually operate, identifying where controls break down, and helping organizations fix the issues that truly matter.
Outside of security, Ben trains Brazilian Jiu Jitsu and spends time working on his homestead with his family, raising chickens, maintaining a garden, and expanding a growing orchard.
