Dynamic Application Security Testing (DAST), also known as black-box testing, is a security testing methodology that evaluates a running application by simulating real-world attacks. Unlike static testing, DAST doesn't require access to the source code—it analyzes the application from the outside, just like an attacker would. DAST is ideal for identifying runtime vulnerabilities in web applications and APIs, making it a critical part of a comprehensive security program.
Examines applications in their working state to uncover vulnerabilities.
Simulates external attacks against publicly exposed interfaces.
Uses advanced scanning engines to detect vulnerabilities such as:
Manual efforts complement automated scans to identify logic flaws and complex vulnerability chains.
Helps find bypasses or chained vulnerabilities that tools may miss.
Tests across multiple environments: staging, pre-production, and production.
Supports traditional, cloud-native, and containerized environments.
Provides detailed findings with risk levels and proof-of-concept exploits.
Includes remediation guidance to help teams fix issues quickly.
- Tests applications the way attackers would, revealing vulnerabilities from an external viewpoint.
- Detects issues that only appear during runtime, such as authentication bypasses.
- Works without access to the application's source code.
- Suitable for third-party apps or closed-source systems.
- Regular DAST scans protect live applications against emerging threats.
- Identifies weaknesses in real-time user interactions.
- Helps meet requirements for PCI-DSS, HIPAA, GDPR, and ISO 27001.
- Maintains audit-ready reports and evidence of security testing.
- When integrated into CI/CD pipelines, ensures each build is tested.
- Provides rapid feedback for DevOps and security teams.
- Educates developers on common vulnerabilities.
- Encourages secure design and implementation practices.
- Automated testing reduces manual security review time.
- Scales easily across multiple applications and APIs.
DAST identifies vulnerabilities that could be exploited by real attackers, such as:
Ensures deployed applications are secure by identifying security flaws missed during development.
Automated scans integrate into SDLC, especially during staging and pre-production phases.
Helps assess which vulnerabilities pose the greatest risk and prioritize remediation.
Avoid reputational damage by finding and fixing flaws before adversaries discover them.
