Secure Halo provides cybersecurity assessment services that evaluate organizational security posture across multiple compliance frameworks and standards. The service uses an Enterprise Security Assessment (ESA) methodology that examines six domains: data security, external business operations, internal business operations, physical security, insider threat, and mobility. The assessments evaluate policies, procedures, behaviors, and technical security controls against frameworks including NIST Cybersecurity Framework 1.1 and 2.0, NIST SP 800-53, NIST SP 800-171, NIST SP 800-30, COBIT, ISO, PCI-DSS, and CIS Implementation Groups 1, 2, and 3. Specific assessment services include NIST CSF and 800 Series assessments, FFIEC cybersecurity assessments for financial institutions, NYCRR Part 500 compliance reviews, HIPAA compliance reviews for healthcare organizations, CIS Implementation Group assessments, and CMMC 2.0 readiness and remediation services for Department of Defense contractors. The methodology incorporates human-centered approaches that focus on behavioral patterns and insider threats. Assessments cover endpoint, server, and network security controls, supply chain vulnerabilities, administrative strategies, physical security risks, and mobile security challenges including BYOD policies.
