4th.GRC™ — Enterprise Agentic AI Governance Platform

A Policy-as-Code, Agentic Workflow, and Trust Assurance Framework for AI Systems

---

🚀 Executive Summary

4th.GRC™ is an enterprise-grade Agentic AI Governance Platform combining:

• Policy-as-Code (PaC)
• AI risk & compliance automation
• Agentic workflows (Semantic Kernel / LangGraph)
• FastAPI microservices
• Streamlit analytics apps
• Azure-native integrations

The platform evaluates AI systems against standards like:

• ISO/IEC 42001 (AI Management System — AIMS)
• NIST AI RMF 1.0
• SOC 2 Trust Services Criteria
• HIPAA / HITECH
• EU AI Act (mapping in progress)

It produces scorecards, system cards, and audit-ready artifacts designed for:

• Enterprises
• Regulated industries
• Government R&D
• Academia
• Startups building responsible AI systems

⚙️ Quick Start (Developer Edition)

1. Clone the repo

git clone https://github.com/<org>/4th.grc.git
cd 4th.grc

2. Create virtual environment

python -m venv .venv
source .venv/bin/activate          # macOS/Linux
.\.venv\Scripts\activate         # Windows

3. Install dependencies

pip install -r requirements.txt

4. Start the PolicyEngine API

bash scripts/dev_run_policyengine.sh

Or:

uvicorn services.policyengine_svc.main:app --reload --port 8080

5. Launch the TrustOps Scorecard UI

bash scripts/dev_run_scorecard.sh

Or:

streamlit run apps/scorecard/streamlit_app.py

🛡 Security & Compliance Posture

✔ Security Controls

• Input validation across all schemas
• Evidence sanitization logic
• Azure Key Vault integration for secrets
• API authentication via APIM / OAuth2
• Container-ready for sandboxing

✔ Compliance Readiness

• System card generation (SYSTEM_CARD.md)
• Deterministic rule evaluation
• Versioned profiles for GRC provenance
• Exportable scorecards for audits
• GitOps-friendly PaC workflows

✔ Governance Guarantees

• Declarative governance
• Immutable policy artifacts
• Cross-standard governance alignment
