NIST RMF Cloud Security Hardening — Pre-Commit & Pre-Merge Compliance Gate

ControlGate is an AI-powered agent skill that scans your code changes against the NIST SP 800-53 Rev. 5 security framework before every commit and merge. It maps findings directly to specific NIST control IDs, providing traceable compliance evidence and actionable remediation guidance.

Quick Start

# Install
pip install controlgate

# Scan staged changes
controlgate scan --mode pre-commit --format markdown

# Scan PR diff against main
controlgate scan --mode pr --target-branch main --format json markdown

How It Works

Developer writes code
       ↓
git commit / Pull Request
       ↓
ControlGate intercepts the diff
       ↓
8 Security Gates scan against 370 non-negotiable NIST controls
       ↓
Verdict: BLOCK 🚫 / WARN ⚠️ / PASS ✅

The Eight Security Gates

#	Gate	NIST Families	What It Catches
1	🔑 Secrets	IA-5, SC-12, SC-28	Hardcoded creds, API keys, private keys
2	🔒 Crypto	SC-8, SC-13, SC-17	Weak algorithms, missing TLS, ssl_verify=False
3	🛡️ IAM	AC-3, AC-5, AC-6	Wildcard IAM, missing auth, overprivileged roles
4	📦 Supply Chain	SR-3, SR-11, SA-10	Unpinned deps, missing lockfiles, build tampering
5	🏗️ IaC	CM-2, CM-6, SC-7	Public buckets, 0.0.0.0/0 rules, root containers
6	✅ Input	SI-10, SI-11	SQL injection, eval(), exposed stack traces
7	📋 Audit	AU-2, AU-3, AU-12	Missing security logging, PII in logs
8	🔄 Change	CM-3, CM-4, CM-5	Unauthorized config changes, missing CODEOWNERS

Installation

From Source

git clone https://github.com/YOUR_ORG/controlgate.git
cd controlgate
python3 -m venv .venv && source .venv/bin/activate
make install-dev

As a Pre-Commit Hook

# .pre-commit-config.yaml
repos:
  - repo: local
    hooks:
      - id: controlgate
        name: ControlGate Security Scan
        entry: python -m controlgate scan --mode pre-commit --format markdown
        language: python
        always_run: true

As a GitHub Action

Copy hooks/github_action.yml to .github/workflows/controlgate.yml in your repo.

Configuration

Create a .controlgate.yml in your project root:

baseline: moderate              # low | moderate | high
catalog: baseline/nist80053r5_full_catalog_enriched.json

gates:
  secrets:    { enabled: true,  action: block }
  crypto:     { enabled: true,  action: block }
  iam:        { enabled: true,  action: warn  }
  sbom:       { enabled: true,  action: warn  }
  iac:        { enabled: true,  action: block }
  input:      { enabled: true,  action: block }
  audit:      { enabled: true,  action: warn  }
  change:     { enabled: true,  action: warn  }

thresholds:
  block_on:   [CRITICAL, HIGH]
  warn_on:    [MEDIUM]
  ignore:     [LOW]

exclusions:
  paths: ["tests/**", "docs/**", "*.md"]

CLI Usage

# Scan staged changes (pre-commit mode)
controlgate scan --mode pre-commit --format markdown

# Scan PR diff
controlgate scan --mode pr --target-branch main --format json markdown sarif

# Scan a saved diff file
controlgate scan --diff-file path/to/diff --format json

# Output reports to directory
controlgate scan --output-dir .controlgate/reports --format json markdown sarif

Output Formats

Format	Use Case
markdown	PR comments, terminal output
json	Programmatic consumption, dashboards
sarif	GitHub Code Scanning integration

Development

make install-dev    # Install with dev dependencies
make test           # Run tests
make test-cov       # Run tests with coverage
make lint           # Lint with ruff
make format         # Auto-format code
make typecheck      # Type check with mypy
make check          # Run all checks (lint + typecheck + test)
make build          # Build distribution packages

AI Agent Skills

ControlGate provides native skills for popular AI coding assistants. These skills teach the agents how to proactively scan your code for NIST 800-53 R5 compliance and automatically apply remediations.

The agent prompts and workflows are located in the skills/ directory and are published to their respective marketplaces/repositories:

• Antigravity: Full workflow definitions available in skills/antigravity/controlgate/
• Cursor: Repository rules available in skills/cursor/.cursorrules
• Claude Code: System prompt instructions in skills/claude_code/.clauderules
• CodeEx: Integration prompts in skills/codeex/instructions.md

Test Suite

To validate the capabilities of ControlGate, we maintain a standalone test suite at sadayamuthu/controlgate-test-suite. This suite contains intentionally vulnerable projects spanning multiple languages and frameworks, specifically designed to trigger each of the 8 Security Gates. It is automatically executed in the CI pipeline to ensure zero regression in detection capabilities.

Data Source

Powered by the NIST Cloud Security Baseline (NCSB) enriched catalog:

• 1,189 controls across 20 families
• 370 non-negotiable at Moderate baseline
• 247 code-relevant controls mapped to automated scanning rules
