Runtime Security Testing

Test Your Live Applications Through an Attacker's Eyes:
DAST Security Analysis

Dynamic Application Security Testing (DAST)

DAST tests your web applications and APIs from the outside while they are running. From a real attacker's perspective, we detect vulnerabilities such as SQL Injection, XSS and Authentication Bypass. No source code access is required; with a black-box testing approach we reveal your application's true security posture.

What Do We Offer? DAST Service Scope

We deliver the DAST engagement not as a mere "automated scan" but as a comprehensive security assessment supported by manual verification, business logic testing and realistic attack scenarios. Every finding is reported in a proven (PoC) and actionable format.

Web Application Scanning

All web assets — traditional web applications, SPAs (React, Angular, Vue), portals and admin panels — are scanned for OWASP Top 10 and beyond. A combination of automated crawling + manual discovery is used.

API Security Testing

A dedicated test methodology for REST, GraphQL and SOAP APIs. Authentication/authorization bypass, IDOR, missing rate limiting, mass assignment and API-specific vulnerabilities are tested.

Authentication Testing

Login bypass, brute force resilience, session management, password policy, MFA bypass and account takeover scenarios are tested. OAuth/OIDC implementations are assessed specifically.

Authorisation Testing

Horizontal and vertical privilege escalation, IDOR (Insecure Direct Object Reference), role-based access controls and multi-tenant isolation weaknesses are tested.

Business Logic Testing

Business logic flaws that automated tools cannot catch are tested manually: price manipulation, workflow bypass, race conditions and negative-scenario abuse.

Proof with PoC

A Proof of Concept (PoC) is provided for every finding: in HTTP request/response, screenshot, video or script format. False positive risk is minimised and findings are reported as "proven".

SQL Injection

Manipulation of database queries

XSS

Cross-Site Scripting attacks

Auth Bypass

Authentication bypass

IDOR

Unauthorised object access

SSRF

Server-Side Request Forgery

CSRF

Cross-Site Request Forgery

Session Hijacking

Session takeover

Info Disclosure

Sensitive information leakage

Who Is It For? Target Audience and Scenarios

Any organisation with an internet-facing web application or API is a potential DAST candidate. DAST is especially critical for systems that process customer data, perform financial transactions or are subject to regulation.

  • E-commerce platforms: Online stores where the security of payment systems, customer data and order processes is critical.
  • Finance and banking: Online banking, payment gateways, investment platforms and fintech applications.
  • SaaS providers: Cloud applications running on multi-tenant architecture and hosting customer data.
  • Healthcare: Portals, appointment systems and health applications processing patient data (KVKK/HIPAA).
  • Corporate portals: Employee self-service, supplier portals, customer extranet systems.

Why Is DAST Indispensable?

SAST analyses the source code but cannot see runtime behaviour. Configuration errors, deployment issues, runtime-specific vulnerabilities and the real attack surface are revealed only by DAST. An application being "secure in code" does not mean it is "secure when running". DAST tests how your application behaves in the real world.

How Does the Process Work? Scan-to-Secure Pipeline

We treat DAST not as a "one-off scan" but as a structured process involving discovery, scanning, manual verification and closure validation. Every step is executed in a predefined, traceable manner.

Scoping and Planning

Target URLs, the test environment, authentication credentials, constraints and delivery expectations are clarified. The production/staging environment choice and the test window are determined.

Reconnaissance

The application surface is mapped: endpoints, parameters, forms, APIs, hidden directories. The technology stack and potential attack vectors are identified.

Automated Scanning

Comprehensive automated scanning is performed with industry-standard tools. OWASP Top 10 and beyond vulnerability categories are tested systematically.

Manual Verification

Automated findings are verified manually and false positives are eliminated. Business logic tests and authentication/authorization bypass attempts are performed manually.

Reporting

An executive summary and a technical detail report are produced. For every finding, a PoC, risk assessment, CVSS score and remediation recommendation are provided.

Re-test and Closure

After remediation, re-testing is performed to confirm closure. Remaining risks and accepted exceptions are documented.

Authenticated vs Unauthenticated Testing

Unauthenticated test: The attack surface from an anonymous user's perspective. Login bypass, public endpoint vulnerabilities. Authenticated test: Internal functions from a logged-in user's perspective. Privilege escalation, IDOR, business logic flaws. A comprehensive DAST engagement should include both perspectives.

Deliverables Proven and Actionable

The deliverable set is structured to enable rapid remediation by technical teams, risk visibility for management and audit requirements for compliance teams.

Executive Summary
Aggregation of risk themes, highlighting of critical findings, an overall security posture assessment. An accessible format for non-technical stakeholders.
Technical Detail Report
Finding-level details: vulnerability description, affected endpoint, HTTP request/response, CVSS score, PoC and step-by-step remediation guidance.
Proof of Concept (PoC)
Exploitation evidence for every finding: cURL commands, Burp Suite requests, screenshot/video recordings. False positive risk is minimised.
Prioritised Finding List
Findings ranked by risk level, ease of exploitation and business impact. An actionable format aligned with sprint planning.
Remediation Guide
General remediation approaches for each vulnerability type, secure coding examples and reference resources. Contributes to developer education.
Re-test Report
Re-testing and closure validation after remediation. Closed, remaining and accepted risks are documented separately.

Frequently Asked Questions About DAST

Positioning DAST correctly starts with clarifying expectations. The answers below address the topics organisations most frequently clarify.

What is the difference between DAST and SAST?
SAST (Static) analyses the source code and does not run the application. DAST (Dynamic) tests the running application from the outside, with no source code access required. SAST finds coding errors; DAST finds runtime vulnerabilities. The two methods complement each other; both are necessary for comprehensive security.
Should DAST be performed in the production environment?
Preferably in a staging/test environment. However, if staging does not fully mirror production, it can also be performed in production with careful planning. Aggressive tests (DoS, brute force) can run in staging, passive tests in production. The environment choice depends on a risk and scope assessment.
How often should DAST be performed?
A comprehensive DAST at least once a year is recommended. It should be repeated before major releases, after significant changes and in line with regulatory requirements. Continuous DAST (CI/CD integration) is ideal for mature organisations.
Does DAST replace penetration testing?
DAST and penetration testing overlap but have different focuses. DAST generally focuses on the web application layer, while a pentest can be broader in scope (network, social engineering, etc.). DAST is more suited to automation, while a pentest requires more manual expertise. The two complement each other.
Can APIs also be tested within DAST scope?
Yes, modern DAST tools can test REST, GraphQL and SOAP APIs. API endpoints are scanned systematically using OpenAPI/Swagger, Postman collections or GraphQL schemas. OWASP API Security Top 10 vulnerabilities are tested with a dedicated methodology.
