Security & Compliance Automation

Project Overview

Developed a comprehensive security and compliance automation platform that provides continuous security monitoring, automated vulnerability management, and compliance reporting across multi-cloud infrastructure. The platform integrates with existing CI/CD pipelines to implement security-as-code practices and ensures consistent security posture across all environments.

Key Achievements

• Vulnerability Detection: 95% reduction in time to detect security vulnerabilities
• Compliance Automation: 100% automated compliance reporting for SOC 2, PCI DSS, and GDPR
• Security Incidents: 80% reduction in security incidents through proactive monitoring
• Remediation Speed: Automated remediation reduced MTTR from days to hours
