-## Features
-
-The CIA Compliance Manager provides enterprise-grade capabilities for comprehensive security management:
-
-- **🔍 Dynamic Security Assessment**: Configure and assess security requirements across the CIA triad with real-time control effectiveness tracking per [Classification Framework](https://github.com/Hack23/ISMS-PUBLIC/blob/main/CLASSIFICATION.md)
-- **💰 Cost Estimation Tools**: Calculate both CAPEX and OPEX based on selected security levels with detailed breakdown and multi-year roadmap planning
-- **📊 Business Impact Analysis**: Evaluate potential impacts using our [Business Impact Analysis Matrix](https://github.com/Hack23/ISMS-PUBLIC/blob/main/CLASSIFICATION.md#business-impact-analysis-matrix) across financial, operational, reputational, and regulatory dimensions
-- **🛠️ Technical Implementation Guidance**: Detailed implementation recommendations for each security level with technology suggestions and best practices
-- **📋 Compliance Mapping**: Map controls to NIST 800-53, ISO 27001, GDPR, HIPAA, SOC2, PCI DSS, and CRA frameworks with automated gap analysis
-- **🎯 Customizable Security Levels**: Tailor security controls to your organization's specific needs and risk profile based on classification requirements
-- **📝 Reporting and Documentation**: Generate comprehensive reports for stakeholders at technical and executive levels with automated evidence collection
-- **💵 ROI Calculator**: Measure return on investment for security implementations against potential breach costs and business impact
-- **🎭 Threat Modeling Integration**: STRIDE analysis with attack tree visualization for comprehensive risk assessment
-- **🏷️ Data Classification Framework**: Apply systematic classification based on confidentiality, integrity, and availability requirements
