Services / Web Application & API Testing

Web Application & API Penetration Testing

Focused, manual-first assessment of your web applications and APIs — covering authentication weaknesses, injection flaws, business logic errors, and API-specific attack classes. Scoped as black, grey, or white box to match your development maturity and timeline.

Web application coverage

OWASP Top 10 — injection (SQL, LDAP, command), broken auth, IDOR, security misconfigurations, vulnerable components, SSRF
Session management — token entropy, fixation, cookie flags, logout behavior
Authentication — MFA bypass, password reset flaws, account lockout policy
Authorization — vertical and horizontal privilege escalation, direct object reference
File upload handling — extension bypass, path traversal, polyglot files
XSS (stored, reflected, DOM-based) with realistic payload demonstration
Business logic — price manipulation, workflow bypass, rate limiting gaps

API coverage

OWASP API Top 10 — BOLA (broken object level authorization), broken function-level auth, mass assignment, unrestricted resource consumption
REST endpoint enumeration — undocumented routes, version discrepancies
GraphQL — introspection abuse, batching attacks, field-level auth bypass
JWT — algorithm confusion (RS256→HS256), none-algorithm attacks, weak secret brute-force
OAuth 2.0 — redirect URI manipulation, PKCE bypass, token leakage
SOAP / legacy XML — XXE, WSDL disclosure, parameter tampering

Methodology

1 · Reconnaissance

Application fingerprinting, technology stack identification, crawl and sitemap analysis, JavaScript source review for endpoint leakage, and API schema discovery (Swagger/OpenAPI, GraphQL introspection).

2 · Authentication testing

Login flow analysis, MFA implementation review, password reset chain testing, session token entropy and rotation analysis, OAuth/OIDC flow review, and JWT claim manipulation.

3 · Authorization testing

IDOR testing across all object types, function-level access control (admin endpoints reachable from unprivileged roles), and multi-tenant isolation verification between user accounts.

4 · Input validation

SQL injection (manual + blind), LDAP injection, command injection, template injection, XSS across all reflection points, XXE in XML parsers, and path traversal in file operations.

5 · Business logic

Application-specific workflow testing — price manipulation, coupon/discount stacking, checkout bypasses, feature flag abuse, and any workflow where sequence-of-operations matters.

6 · Reporting

Developer-ready findings with exact endpoint, parameter, payload, and HTTP request/response evidence. Remediation guidance written for your tech stack. Portal tracks each finding status as your team remediates.

Best for

Pre-launch application security review
Post-deployment security validation after major feature changes
SOC 2 Type II, PCI-DSS, HIPAA application assessment requirements
B2B SaaS platforms where customer data isolation is critical
APIs consumed by mobile apps or third-party integrations
