1,200+ Applications Tested | Expert Security Assessment
Modern web applications demand modern security testing. Our professional penetration testing services go beyond automated scans to discover business logic flaws, API vulnerabilities, authentication bypasses, and application-specific weaknesses in SaaS platforms, microservices, and cloud-native architectures. We test like real attackers to find what automated tools miss.
Understanding vulnerabilities threatening modern web applications and business operations
Broken authorization in REST, GraphQL, and microservices APIs exposing sensitive data, enabling unauthorized operations, and bypassing business logic. API vulnerabilities represent the fastest-growing attack vector in modern applications.
SaaS application flaws allowing tenant-to-tenant data access, cross-customer privilege escalation, and shared resource exploitation. Single isolation failure compromises entire customer base and destroys business trust.
Application-specific vulnerabilities in workflows, payment processing, inventory management, and user privileges that automated scanners cannot detect. Business logic flaws cause direct financial losses and operational disruption.
JWT token vulnerabilities, session fixation, OAuth misconfigurations, and SSO bypass techniques enabling account takeover and unauthorized access to sensitive application functionality.
Serverless function security gaps, container escape techniques, infrastructure-as-code misconfigurations, and cloud service integration weaknesses unique to modern cloud architectures.
Vulnerable dependencies, insecure API integrations, OAuth token leakage, and supply chain attacks through compromised third-party services integrated into applications.

Common questions about web application penetration testing
Web application testing focuses on complex functionality, business logic, APIs, authentication systems, and data processing rather than static content. Applications require testing of user workflows, multi-tenant architectures, API authorization, state management, and application-specific vulnerabilities that don't exist in simple websites.
Yes. We have extensive experience testing React, Angular, Vue.js, and other JavaScript frameworks. Our SPA testing covers: client-side validation bypass, DOM-based XSS, state management vulnerabilities, JWT token handling, client-side routing security, WebSocket security, and API integration testing.
Our API testing covers: authentication and authorization enforcement, rate limiting validation, input validation and injection testing, mass assignment vulnerabilities, API versioning security, GraphQL introspection and injection, data exposure issues, business logic flaws, and integration security. We test REST, GraphQL, SOAP, and custom API implementations.
Absolutely. Multi-tenant testing is a specialty. We validate: tenant isolation and data segregation, cross-tenant privilege escalation, shared resource security, subscription bypass attempts, customer data access control, and API authorization across tenants. We require test accounts for multiple tenants to thoroughly validate isolation controls.
We offer multiple integration options: automated security scanning in CI/CD pipelines, API-driven testing integrated into deployment workflows, pre-production environment testing, security gate implementation, and webhook notifications. We support Jenkins, GitLab CI, GitHub Actions, CircleCI, and custom pipelines.
Black-box testing simulates external attackers with no internal knowledge—most realistic but limited coverage. Grey-box provides partial knowledge (architecture, test accounts)—balances realism with efficiency. White-box includes source code access—deepest analysis finding code-level flaws. Most clients choose grey-box for optimal cost-effectiveness.
Timeline depends on complexity: simple applications (5-10 days), mid-size SaaS platforms (2-3 weeks), large enterprise applications (4-6 weeks), and complex multi-tenant systems (6-8 weeks). Factors include: API endpoint count, authentication complexity, business logic depth, and integration quantity.
Yes. Our continuous testing services include: sprint-based security reviews, automated testing in CI/CD pipelines, quarterly manual penetration tests, PTaaS (Penetration Testing as a Service) with ongoing vulnerability management, and security consulting during feature development.
Business logic testing requires understanding your application's intended behavior. We: review business requirements and workflows, identify critical functions (payments, authentication, authorization), test unexpected input combinations, attempt workflow bypasses, validate authorization at every step, test edge cases and race conditions. Manual testing is essential—automated scanners cannot understand business context.
Yes. Our OAuth/SSO testing covers: authorization code interception, token leakage, redirect URI validation bypass, state parameter manipulation, scope elevation, refresh token security, PKCE validation, and SSO assertion manipulation. We test major providers (Okta, Auth0, Azure AD, Google) and custom implementations.
