Dynamic Application Security Testing Tool
for Live Web Applications
DerScanner DAST tool scans running applications. To find injections, XSS, authentication flaws, or misconfigurations that show up only at runtime, it sends requests to live web apps and REST APIs. No source code access is required: load an OpenAPI definition and the scanner will map endpoints automatically.

What Is Dynamic
Application
Security Testing
(DAST)?
Dynamic application security testing (DAST) is a black-box method for running web applications. It simulates real attacks and sends requests to the live application through its exposed interfaces.
Find runtime issues like authentication gaps, session handling errors, server misconfigurations, or component interaction vulnerabilities. DAST can test third-party software and live production systems without access to source code.
Reduce Testing Costs
Find common vulnerabilities early. Pentesters can spend past time on deeper, hidden issues instead of the obvious ones.
Increase Frequency
Run DAST scans as often as you need – daily, on every deploy, or on a schedule. Automated scanning keeps pace with your release cycle faster than pentest audits.
Higher Pentest Value
DAST clears out obvious findings before a human pentest begins. Pentesters get a pre-scanned environment and can focus on business logic and complex attack chains instead.
Go with the Dev Flow
Fit DAST scans into your CI/CD pipelines. Flag issues before they hit production and get results in developer-readable reports – with remediation guidance.
Key DerScanner DAST Features
Automated Security
Scanning
DerScanner DAST scanner crawls the application surface, finds endpoints, and runs tests that simulate attacker behavior. It maps URL parameters, form inputs, and API routes from OpenAPI definitions to locate injection points and logic flaws.

REST API Testing
DerScanner accepts OpenAPI definition files or URLs to build a map of API endpoints. It tests each endpoint for injection flaws, broken authentication and access control problems without manual setup.

Reporting &
Risk Prioritization
DerScanner DAST produces detailed reports, including the affected URL, the request that triggered the detection, server response, and severity level.
Findings are prioritized by criticality so security teams can focus on what matters most. Can be mapped to CWE, OWASP Top 10 x WSTG – turning runtime evidence into compliance-ready documentation.



CI/CD Integration

Live Response Verification
How DerScanner DAST Works
DerScanner DAST mimics real attackers to find vulnerabilities in your application environment.
Automated Crawl
Finds all reachable endpoints, including dynamic content, SPAs, and authenticated areas.
Attack Simulation
Runs security tests to find exploitable weaknesses.
Response Verification
Checks responses to confirm vulnerabilities and cut false positives.
Remediation Reports
Gives clear fix instructions for developers and security teams.
Vulnerabilities Detected by DerScanner in Real-Time
Scan live apps
DAST tests applications while it is running – in staging, pre-production, or production. It finds flaws as they exist at runtime, not as they appear in source code.
Scan as often as you like
Run tests after every deployment or on a recurring schedule. The more frequently you scan, the earlier you catch regressions.
No source code needed
DAST analyzes the running application from the outside. No access to source code, build artifacts, or repository credentials required. Works for third-party applications, vendor software, and legacy systems.



Dynamic Analysis Toolset
DerScanner includes several scanning modes, each designed for different types of web application behavior
Traditional DAST
Standard black-box testing that interacts with the application through its web interface, submitting payloads and analyzing responses.
Automatic Scanner
Run scans automatically through CI/CD integrations. Configure scans to run on every deployment to staging or on a schedule defined in your pipeline, so security testing happens in step with the release cycle.
AJAX Web Scanner
Handles asynchronous requests that load content without full page reloads – forms, shopping carts, subscription flows, and other dynamic UI elements.
Fuzzer
Sends unexpected, malformed, and boundary-case inputs to forms, URL parameters, and API endpoints. Catches edge cases that standard payload libraries miss.
Interactive Analysis for SAST/DAST Correlation
DerScanner’s IAST mode correlates SAST and DAST findings for the same application. When comparing DAST vs SAST results, IAST checks whether a vulnerability found in source code is reachable and exploitable at runtime. This cross-validation cuts the number of alerts that need manual review.

On-Premise Deployment
DerScanner DAST is available as an on-premise installation, with full air-gap support for sensitive environments.
Best for defense, finance, government, and other regulated sectors.
Built for CI/CD Pipelines
DerScanner integrates with Jenkins, TeamCity, Azure DevOps, and GitLab CI. DAST scans trigger automatically after deployment to staging.
Results are available in the DerScanner UI and via email reports – ready for review on the same day the change ships.
Findings You Can Reproduce
Every finding includes the affected URL, the HTTP method, the test payload, and the server response. Developers see exactly what the scanner sent and what came back, so they can reproduce, validate, and fix the issue without going back and forth.
Correlation with SAST
DerScanner DAST and SAST results can be correlated through IAST mode.
Vulnerabilities found in source code are confirmed against runtime behaviour – and findings that are not actually reachable drop out of the priority list.
Why Modern Organizations Need DAST
Reduce breach risk
Web application attacks account for a large share of confirmed breaches (Verizon DBIR 2025). DAST finds the vulnerabilities that attackers actually exploit: injection flaws, authentication weaknesses, misconfigurations.
Accelerate releases
Automated DAST scans run inside CI/CD pipelines without blocking developers. Security testing happens in parallel with deployment, not as a gate at the end of a quarterly cycle.
Ensure compliance
PCI DSS, ISO 27001, and SOC 2 require evidence of application security testing. DAST scan reports document what was tested, what was found, and what was remediated – ready for the next audit.
Lower remediation costs
Vulnerabilities found in staging cost a fraction of what they cost in production. Continuous DAST scanning catches regressions early, when the developer who introduced the change still has context.
