What I Do

Three ways in

Advisory Services

Security posture assessments across the full spectrum, and roadmaps that can be sequenced, funded, and staffed. Findings written for engineers and executives alike.

Incident Remediation

Remediation and recovery support during active incident response — containment, rebuild, and the control changes that keep the same door from opening twice.

Architecture

Network, identity, endpoint, and detection designed as one system rather than seven products. Cloud, hybrid, and the on-prem estate that is not going anywhere.
