Vulnerability Management
Automated identification and remediation of security vulnerabilities: - Vulnerability Scanning: Automated security scanning of systems and applications - Patch Management: Automated deployment of security updates - Risk Assessment: Automated calculation of vulnerability risk scores - Remediation Orchestration: Coordinated automated fix deployment
Compliance and Governance
Automated enforcement of security policies and regulations: - Policy Enforcement: Automated implementation of security policies - Compliance Monitoring: Continuous validation of regulatory requirements - Audit Logging: Automated collection and analysis of security audit data - Report Generation: Automated creation of compliance reports
