Sebastien Arseneault
Founder & Principal Operator
Federal cybersecurity operations background including Navy ship system cyber test planning at OPTEVFOR, Air Force network defense, and red team operations on federal healthcare contracts. BS and MS in Cybersecurity from ECPI University.
I built Deep Woods to bring the same depth of offensive testing I've done inside federal programs to organizations that need more than a scan report. Hands-on work, real tradecraft, and the clearance to operate where it matters.
Federal roots. Offensive focus.
Direct experience from federal cybersecurity operations. Cyber test plans for Navy ship systems. Red team operations on federal healthcare contracts. Offensive capabilities built for organizations that take security seriously.
This background shapes how we work. We understand compliance requirements, but we focus on actual threats — how federal programs operate and how adversaries think about breaking them.
Cleared. Registered. Operational.
