Contrast Assess uses an agent that instruments applications with sensors.
The sensors look at data flow in real-time and analyze the application from within to detect security issues.

How It Works
The platform examines:
- Libraries, frameworks, and custom code
- Configuration information
- Runtime control and data flow
- HTTP requests and responses
- Back-end connections
Testing Environments
The tool is designed for testing environments including:
- Test servers
- QA environments
- Staging servers
- Developer workstations

IDE Integration
The platform integrates with development tools like Visual Studio, allowing developers to identify and remediate vulnerabilities without leaving their integrated development environment.
