DefenseLogix provides vCISO-led cybersecurity advisory for organizations that need experienced guidance without building a full internal leadership stack.
The firm focuses on practical security work across communications, operations, audit support, compliance, and emerging technology. That includes fractional security leadership, audit and assessment support, email security and domain trust, government and CMMC readiness, AI risk management, technical documentation and training, and selected cyber-physical reviews.
DefenseLogix is built for organizations that need more than generic advice. Many clients need an advisor who can assess risk, explain priorities clearly, help shape a roadmap, support audit preparation, and help move implementation forward in environments where time, staffing, and internal bandwidth are limited.
Scott Arenson is a cybersecurity advisor, technical writer, and CISO with 25 years of enterprise IT experience and more than a decade focused on cybersecurity risk, compliance, and security operations. He helps SMBs and regulated organizations strengthen security programs through assessments, policy development, audit-ready documentation, cloud security reviews, and control mapping across frameworks including NIST, HIPAA, SOC 2, CMMC, FFIEC, and GLBA. He is a Cyber AB CMMC Registered Practitioner who helps defense contractors prepare for CMMC Level 2, including CUI enclave design, GCC High architecture decisions, System Security Plans, and evidence collection across all 110 NIST SP 800-171 requirements and 320 assessment objectives. Scott is the founder of DefenseLogix and has worked with organizations ranging from global technology companies to healthcare, financial services, and defense-related clients.
Recommendations are tied to usable outcomes: documents, configurations, runbooks, training. Not just slides.
Security is treated as both a technical and communication problem. Clarity matters as much as control selection.
Audit support includes controls, evidence, documentation, and readiness thinking. Not just framework crosswalks.
Documentation, training, and operational clarity are part of security maturity, not an afterthought.
The focus is on practical progress, not unnecessary bureaucracy. Every engagement moves something forward.
Tell us what you are dealing with now, what kind of support you may need, and whether you are looking for a focused project, ongoing advisory, or both.
