Web Application Penetration Testing – Protecting your Data & Dollar

Web Application Penetration Testing

Safeguard your mission-critical applications and protect your users’ trust with Tranchulas advanced, attacker-informed assessments for modern web applications, APIs, and microservices.

From dynamic single-page applications and mobile-ready progressive web apps to intricate APIs powering microservices and serverless backends, the modern web is more complex—and more vulnerable—than ever. At Tranchulas, our seasoned penetration testers employ the latest methodologies and industry-standard frameworks like OWASP and MITRE ATT&CK for Web. By simulating real-world attack patterns, uncovering zero-day exploit vectors, and verifying business logic integrity, we empower you to navigate today’s threat landscape with confidence and deliver secure, frictionless experiences to your users.

Why Web Application Penetration Testing?

Modern web applications are not just code—they’re ecosystems of interconnected services, rich client-side logic, and continuous deployment pipelines. Attackers capitalize on any gap: weak session handling, misconfigured APIs, sensitive data exposure, or inadequate input validation. Tranchulas web penetration testing cuts through complexity and camouflage, revealing hidden vulnerabilities before malicious actors exploit them. We ensure your brand reputation, compliance status, and user trust remain unshaken.

Comprehensive Risk Visibility

Identify critical flaws across front-end frameworks (React, Angular, Vue) and back-end logic (Node.js, Python, Java) to maintain a robust, end-to-end security posture.
Advanced Lateral Movement Testing

Test REST and GraphQL endpoints, containerized microservices, and serverless APIs to prevent unauthorized data access and abuse of business logic.
Adaptive Testing Techniques

Utilize our advance scanning, integration with CI/CD pipelines, and advanced tools like Burp Suite Pro, ZAP, and custom fuzzers to catch emerging threats early.
Continuous Security Alignment

Align with OWASP Top Ten while incorporating modern TTPs from the MITRE ATT&CK for Web matrix, ensuring your defenses stay a step ahead.

Our Approach & Methodology

At Tranchulas, we blend human ingenuity with automated precision:

Intelligent Reconnaissance & Asset Discovery

Enumerate hidden endpoints, map API schemas, detect unlinked functionalities, and uncover stale subdomains or forgotten staging environments.

Client-Side & Server-Side Analysis

Identify vulnerabilities in front-end frameworks (e.g., DOM-based XSS) and server-side weaknesses (e.g., SQL injection, XXE, SSRF) that could compromise data integrity and user privacy.

Business Logic & Access Control Testing

Examine authorization flows, payment processes, and role-based access controls to ensure complex user journeys can’t be manipulated for financial fraud, data leakage, or privilege escalation.

API & Microservice Stress Testing

Probe API endpoints for injection flaws, insecure tokens, rate-limit bypasses, and CORS misconfigurations. Assess microservices for insecure service-to-service communication and container orchestration missteps.

Reporting, Recommendations & Integration

Provide clear, prioritized remediation paths, mapping each finding to an actionable solution. Integrate testing results directly into your GitOps or DevSecOps workflows, enabling ongoing improvement and frictionless collaboration between security and development teams.

Technology & Standards Alignment

We leverage best-in-class tools, methodologies, and compliance frameworks:

Frameworks & Tools

Burp Suite Pro, OWASP ZAP, custom JS fuzzers, API-specific testing scripts, GraphQL introspection checks, and container security scanners.

Standards & Benchmarks

OWASP Top Ten, OWASP Web Security Testing Guide (WSTG), MITRE ATT&CK for Enterprise (Web Techniques), and CIS Benchmarks for web servers and frameworks.

Compliance & Governance

PCI-DSS, HIPAA, GDPR, SOC 2—align testing outcomes with regulatory requirements to streamline audits and foster customer trust.
