Operators, not auditors.
Deep Woods Security is a boutique offensive security firm based in Virginia Beach. We specialize in penetration testing, red team operations, and AI security for organizations where failure isn't an option.
Federal roots. Offensive focus.
Our team brings direct experience from federal cybersecurity operations. We've developed cyber test plans for Navy ship systems, conducted red team operations on federal healthcare contracts, and built offensive capabilities for organizations that take security seriously.
This background shapes how we work. We understand compliance requirements, but we focus on actual threats. We know how federal programs operate, and we know how adversaries think about breaking them.
