Building Vulnerability Dashboard with DefectDojo

Overview

DefectDojo is an open-source application vulnerability management platform that aggregates findings from 200+ security tools, deduplicates results, tracks remediation progress, and provides executive dashboards. It serves as a central hub for vulnerability management, integrating with CI/CD pipelines, Jira for ticketing, and Slack for notifications. DefectDojo supports OWASP-based categorization and provides REST API for automation.

API_KEY = "your_api_key_here"
HEADERS = {"Authorization": f"Token {API_KEY}", "Content-Type": "application/json"}

# Create Product Type
resp = requests.post(f"{DD_URL}/product_types/", headers=HEADERS, json={
    "name": "Web Applications",
    "description": "Customer-facing web application portfolio"
})
product_type_id = resp.json()["id"]

# Create Product

    "name": "Customer Portal",
    "description": "Main customer-facing web application",
    "prod_type": product_type_id,
    "sla_configuration": 1,
})
product_id = resp.json()["id"]

# Create Engagement
resp = requests.post(f"{DD_URL}/engagements/", headers=HEADERS, json={
    "name": "Q1 2024 Security Assessment",
    "product": product_id,
