Web Application & API Penetration Testing
Your web apps and APIs are where your customers' data lives, and where the most damaging breaches happen. Pentiq's web application penetration testing covers authenticated and unauthenticated paths, business logic flaws, and API edges the way an attacker with time and intent actually approaches them. Mapped to OWASP, but never limited by it.
Testing Coverage
Comprehensive web application security assessment
Authentication & Session Management
Login mechanisms, session handling, password policies, MFA flows, and privilege management.
Input Validation & Injection
SQL injection, XSS, command injection, XXE, and other input-based vulnerability classes.
Business Logic Testing
Workflow abuse, parameter manipulation, race conditions, and application-specific vulnerabilities.
API Security Assessment
REST/GraphQL APIs, authentication, authorization, rate limiting, and data exposure.
Client-Side Security
JavaScript security, DOM manipulation, client-side controls bypass, and SPA vulnerabilities.
Data Protection
Sensitive data exposure, encryption implementation, and data handling vulnerabilities.
OWASP Coverage
Comprehensive testing against OWASP Top 10 and beyond
Testing Process
Expert-led methodology combining automated and manual techniques
Application Mapping
Comprehensive discovery of functionality, endpoints, parameters, and data flows.
Automated Scanning
Baseline vulnerability identification using industry-leading tools and custom scripts.
Manual Testing
Expert analysis of business logic, complex workflows, and application-specific risks.
Exploitation & Impact
Safe demonstration of vulnerability impact with clear evidence and remediation guidance.
Common questions
Frequently asked questions.
Do you test authenticated and unauthenticated paths?
Both. We test the public surface and then any authentication tiers in your application using credentials you provide. Business-logic abuse, role-based access control, and API authorisation are all in scope by default.
How long does a web app test take?
A typical mid-size SaaS application with 5-15 user roles takes 1-2 weeks of testing. Larger applications or those with extensive APIs scope to longer. We confirm timing at scoping.
Do you test our APIs separately?
APIs can be in-scope as part of the web application engagement, or scoped separately if the API is the primary product. We follow OWASP API Top 10 plus business logic testing tailored to your API's purpose.
Can you test against our staging environment?
Yes. Staging is often preferred to avoid impacting production. We just need staging to be a faithful replica of production: same code, same configuration, similar data shape.
Compliance
Findings from a Web Application & API engagement commonly support evidence for PCI DSS Requirement 11.4, ISO 27001 Annex A.8.29, and SOC 2 Trust Services Criteria.
