Let me help your organization meet compliance and more importantly - stay compliant! I provide recommendations to small business owners that are cost-effective to meet cybersecurity compliance requirements and lessen cybersecurity risk. Specialties: cyber risk assessments, security gap analysis, policy and procedure development, system security plan (SSP) development, Plan of Action and Milestones (POA&M) creation Frameworks: CMMC, NIST 800-171, NIST Cybersecurity Framework Education: Doctorate - Cybersecurity (in-progress), Masters – Administration, Masters – Computer Science, Bachelors – IT Management Certifications: CMMC Certified Professional (CCP), CISSP, PMP, CRISC, CCSP, HCISPP, AWS Cloud Practitioner
