Ambyr Leidig

I'm a cybersecurity executive with 20+ years of experience building and leading enterprise security programs — spanning SOC leadership, MSSP oversight across 100+ client environments, and enterprise risk governance for classified DoD/Space Force programs. I hold CISSP, CISM, and CMMC CCP credentials, an active TS/SCI clearance, and I currently serve as a Lieutenant Colonel (O-5) in the U.S. Army Reserve, where I apply joint-staff cyber risk assessment, mission assurance, and crisis-leadership skills to enterprise security strategy. My background pairs hands-on practitioner depth in RMF, ATO, and CMMC/NIST 800-171 compliance with a track record of building security programs from the ground up, leading through incidents and audits, and translating technical risk into terms executive leadership and boards can act on. I've led SOC teams, launched an after-hours MSSP model to expand 24/7 coverage, directed enterprise architecture reviews protecting $100M+ in IP, and advised Authorizing Officials on ATO decisions for mission-critical systems. I'm looking for remote opportunities where I can own enterprise security strategy end-to-end — risk governance, regulatory compliance, incident response, and board-level communication — whether in an enterprise CISO/Deputy CISO seat or a fractional/vCISO capacity.
