Features

• Asset Discovery & Management: Comprehensive discovery and cataloging of internet-facing assets including domains, subdomains, IP addresses, and web services. Supports asset grouping, real-time inventory updates, and multi-workspace organization for efficient asset lifecycle management.
• Vulnerability Assessment: Continuous scanning for vulnerabilities, misconfigurations, and security exposures across the entire attack surface. Advanced issue tracking with detailed risk analysis, prioritization, and remediation guidance.
• Technology Detection: Automated identification and cataloging of technologies, frameworks, and services running on discovered assets. Provides insights into technology stacks and potential security implications.
• Distributed Scanning Engine: High-performance distributed workers with auto-scaling capabilities for parallel processing of scanning tasks. Job orchestration and registry system for managing complex scanning workflows.
• Tool Integration: Extensible framework for integrating various security scanning tools and services. Supports custom tool configurations and automated execution pipelines.
• AI Assistant Integration: Model Context Protocol (MCP) server integration enabling AI assistants to query asset data, generate insights, and assist with security analysis through natural language interfaces.
• Workflow Automation: Configurable workflows for automated scanning schedules, alert responses, and remediation processes. Template-based approach for standardizing security operations.
• Real-time Monitoring & Notifications: Continuous monitoring of asset changes with instant notifications for new discoveries, vulnerabilities, and configuration changes. Statistics dashboard with trend analysis and reporting.
• Advanced Search & Analytics: Powerful search capabilities across all asset data with filtering and faceting. Comprehensive analytics for attack surface metrics, risk trends, and compliance reporting.

System Architecture

The system runs on a distributed architecture consisting of:

• A web-based console for user interaction and monitoring.
• A core API service handling business logic, data persistence, and job orchestration.
• Distributed workers for high-performance scanning tasks with auto-scaling capabilities.
• PostgreSQL database for data storage and Better Auth for authentication.

Installation

To quickly get started with OASM using Docker:

1. Clone the repository:

   git clone https://github.com/oasm-platform/oasm-docker.git
   cd oasm-docker

2. Rename the example environment file:

   cp .env.example .env

3. Start the services:

   docker compose up -d

This will launch the entire system, including the console, core API, workers, and database. Access the application at the configured URL (http://localhost:6276).
