WEB APPLICATION PENETRATION TESTING (Web App Pentest)

Find and fix the flaws attackers exploit. Our Web Application Penetration Testing service combines automated scanning with deep manual analysis to uncover injection flaws, broken auth, insecure direct object references, and logic issues that scanners miss.

Trusted cybersecurity services partner worldwide

Overview

Modern web applications power business workflows, customer journeys, and sensitive data flows. A single exploitable vulnerability can expose user data, enable fraud, or allow full system compromise. Our Web Application Penetration Testing service provides a hands-on examination of your web apps — from public-facing websites and single-page applications to APIs and microservices — identifying security weaknesses and delivering prioritized, actionable remediation steps.

We use a hybrid approach: automated reconnaissance and scanning to map the attack surface, followed by expert manual verification and exploitation (safe, scoped) to confirm impact. Our methodology aligns with OWASP Top 10, SANS, and relevant compliance frameworks to help you reduce risk and meet audit needs.


Why choose our Web App Pentest?

  • OWASP-aligned testing: Coverage of injection issues, broken authentication, XSS, CSRF, insecure deserialization, and business logic flaws.

  • Manual verification: Human-led testing to find complex, chained issues that scanners miss.

  • API & SPA expertise: Deep testing for REST/GraphQL APIs, JSON endpoints, and single-page apps (React/Angular/Vue).

  • Actionable remediation: Clear technical fixes + prioritized business impact for engineering teams.

  • Compliance-ready reporting: Reports suitable for PCI, SOC2, ISO27001, and regulatory audits.

  • Retest option: Confirm fixes and reduce residual risk.

How it work

Scoping & Authorization

We document the scope (domains, subdomains, API endpoints, test accounts), define allowed testing methods and time windows, and sign legal authorizations and NDAs. Clear scope prevents unintended impacts and keeps testing legal.

Reconnaissance & Mapping

Passive and active reconnaissance to enumerate endpoints, parameters, technologies, third-party components, and hidden API routes. We build an asset inventory and fingerprint frameworks, libraries, and versions.

Vulnerability Discovery & Exploitation

Combining automated scans with deep manual probing, we verify findings and perform controlled exploitation to demonstrate real impact — from account takeover to escalated privileges and data exfiltration — while avoiding destructive actions unless explicitly authorized.

Reporting & Remediation Support

We produce a prioritized report with proof-of-concept evidence, CVSS/OWASP risk ratings, and step-by-step remediation. We can also provide a remediation workshop or code-level guidance for engineering teams and perform a retest to validate fixes.
