Expanded Expertise

Cybersecurity, CMMC, and AI Governance Expert Witness Support

Modern cybersecurity disputes increasingly involve more than technical breach analysis. They involve questions of governance, compliance, vendor responsibility, data protection, AI use, CMMC readiness, NIST 800-171 implementation, and whether organizations acted reasonably under evolving regulatory expectations.

Mitch Tanenbaum brings more than 35 years of hands-on cybersecurity, privacy, IT, and compliance experience to expert witness engagements. His work is supported by the broader Huttan Holding ecosystem, which includes cybersecurity compliance, CMMC advisory, AI governance, AIGIP training, vCISO services, digital forensics, and regulated-environment technology consulting.

This combination allows Mitch to analyze not only what happened technically, but also whether the organization's cybersecurity program, governance model, vendor controls, documentation, and risk decisions were reasonable for the environment.
