Sentinelai Application Security Platform

From github.com

I describe SentinelAI as an enterprise-grade Application Security Testing (AST) and DevSecOps platform in my Python repository Ai-security-, hosted on @ghkrknkp’s GitHub and started and last updated in 2026-09. It accepts a GitHub repository or ZIP source-code project. My GitHub profile also presents SentinelAI among my cybersecurity projects: my github profile.

  • I combine deterministic security analysis—Semgrep, Bandit, custom AST pattern analysis, and taint dataflow tracing—with contextual AI triage. The analysis traces untrusted inputs through transformations to dangerous execution sinks, and scans for high-entropy secrets and patterns with automatic value masking for AWS, Stripe, GitHub, and private keys. Dependency auditing generates a Software Bill of Materials (SBOM) and scans packages against known CVEs.
  • I describe AI-assisted handling for false-positive verification, root-cause explanation, exploitability rating, attack-path synthesis, and remediation diff or unified patch generation. The attack-path model connects entrypoint vulnerabilities with exposed secrets and vulnerable dependencies. The README describes these AI capabilities but does not explain the underlying providers or the rationale for combining them with deterministic findings.

I describe executive-ready PDF audit reports and SARIF 2.1.0 exports compatible with GitHub Code Scanning. Configurable CI/CD policy checks can block pull requests or deployment pipelines for critical vulnerabilities or low posture scores; the captured README does not specify the exact thresholds or how posture scores are calculated.

  • I organize the backend with backend/app/api/v1/endpoints/ for scan, finding, AI chat, gate, and report REST endpoints; backend/app/core/ for configuration, security helpers, and logging; backend/app/db/ for SQLAlchemy models and session setup; backend/app/schemas/ for Pydantic validation schemas; and backend/app/services/ for ingestion, scanners, AI providers, the risk engine, and reporting.
  • I include backend/scripts/init_db.py as a standalone database initialization script, backend/tests/ for scanner, AST, and API tests, backend/.env for active environment configuration, backend/.env.example as its template, and backend/requirements.txt for Python dependencies. The captured project description does not provide test results.
  • I organize the frontend under frontend/src/: components/ contains UI components such as Sidebar, Badges, Charts, and AI Chat; pages/ contains Dashboard, New Scan, Scan Details, Findings, Reports, and Settings; services/ contains the typed Axios API client; and types/ contains TypeScript data contracts. The root also includes frontend/package.json for React dependencies, frontend/tailwind.config.js for the dark SOC theme palette, and frontend/vite.config.ts for Vite build configuration with an API proxy.

I include samples/vulnerable-app/ as a reference app covering SQL injection, command injection, and SSTI, plus samples/vulnerable-app.zip as a pre-packaged archive for immediate testing. The captured project description does not specify supported languages beyond the repository’s Python label, the CVE data source, scanner configuration, deployment instructions, or measured product performance.

I can run SentinelAI locally with Python 3.10+ and Node.js 18+ with npm; Git is optional when cloning the repository. The backend needs backend/.env, which I can create from .env.example. The default AI provider is mock, so I can use realistic vulnerability validations and fix diffs offline; live Gemini, OpenAI, or Anthropic reasoning requires the matching API key and provider setting.

  • My setup defaults include DATABASE_URL=sqlite+aiosqlite:///./sentinel.db and SYNC_DATABASE_URL=sqlite:///./sentinel.db. The security gate defaults to FAIL_ON_CRITICAL=true and MIN_SECURITY_SCORE=70. I can initialize the SQLite/PostgreSQL tables explicitly with python scripts/init_db.py from backend; starting FastAPI also initializes them through its application lifespan. The tables cover scans, findings, evidence records, secret and dependency findings, attack paths, and scan comparisons.
# Backend, from the backend directory
python -m venv venv
# Windows PowerShell: .\venv\Scripts\Activate.ps1
# Linux/macOS: source venv/bin/activate
pip install -r requirements.txt
uvicorn app.main:app --host <redacted> --port 8000 --reload

# Frontend, from the frontend directory
npm install
npm run dev

I can reach the backend at http://localhost:8000, its Swagger documentation at http://localhost:8000/api/docs, and its health check at http://localhost:8000/health; the frontend development server opens at http://localhost:5173. The documented Uvicorn command uses the literal host placeholder <redacted>, and the guide does not specify its actual value.

  • For a first scan, I go to New Scan at /new-scan, choose ZIP Upload, and upload samples/vulnerable-app.zip. I set App Type to Web API, Internet Facing to Yes, and Data Sensitivity to High before starting the audit. Progress proceeds through language and framework detection, SAST, AI vulnerability triage, attack-path synthesis, and report generation.
  • When I review a finding, I can inspect its Monaco Code Viewer, Source-to-Sink Dataflow Path, and AI Vulnerability Triage; on-demand triage provides root-cause analysis and unified patch generation. Analysts can set findings to CONFIRMED, FALSE_POSITIVE, or FIXED with justification. I can export findings to Jira, download an executive-summary PDF from Scan Details, export OASIS SARIF 2.1.0 for GitHub Code Scanning, or evaluate PR pass/fail compliance with the Security Gate.
