🤖 AI Governance Projects

🛡️ AI-GRIT — AI Governance & Red Team Intelligence Toolkit

Automated NIST AI RMF risk assessment + 25-vector live prompt injection red-teaming against local LLMs (Ollama). Generates CISO-ready PDF reports with executive summary, attack narrative, and 30-day remediation plan powered by Claude AI.

Python Streamlit Ollama NIST AI RMF OWASP LLM Top 10 ISO 42001 HIPAA


☁️ Cloud Security Projects

Automated AWS security auditor replicating the AWS Security Assurance team's engagement workflow. Runs checks across IAM, S3, CloudTrail, and Security Groups — maps every finding to NIST CSF, SOC 2 TSC, and CIS AWS Benchmark v2.0. Generates structured audit evidence packages and CISO-ready PDF reports.
