Identity and session security
Login, MFA, password reset, cookies, tokens, and session lifecycle.
- Session fixation and weak cookie settings
- Authentication bypass and account recovery flaws
- Privilege escalation through broken role handling
Web Application Pentest Auth • business logic • exploit validation
Web application penetration testing services for real production risk.
We test authentication, session handling, authorization, admin flows, data exposure, and business logic so your team gets actionable findings instead of noise.
What we test in web applications
We focus on the areas where attackers actually gain leverage.
Business logic and workflow abuse
Payments, approvals, exports, admin actions, and trust-boundary shortcuts.
- High-value workflow abuse cases
- Missing approval and authorization checks
- Unsafe assumptions between front end and backend
Data handling and exposure
Uploads, downloads, exports, report generation, and data access boundaries.
- PII exposure and insecure direct object references
- File upload, SSRF, and data leakage checks
- Logging, caching, and debug exposure review
How the engagement runs
Fast kickoff, safe execution, evidence, and a clean handoff to engineering.
Step 01
Scope
Define targets, accounts, environments, test windows, and production safety constraints.
Step 02
Test
Manual testing with targeted tooling focused on auth, business logic, and data paths.
Step 03
Report
You receive clear reproduction steps, impact explanation, and remediation guidance.
Step 04
Retest
We validate critical fixes and confirm risk reduction after remediation ships.
FAQ
A few common questions about web application penetration testing.
What does a web application penetration test include?
A typical test includes authentication, session management, authorization, business logic, data access, uploads, exports, admin workflows, and exploit validation under agreed constraints.
How is this different from an automated scan?
Automated scans identify potential weaknesses. Penetration testing adds manual validation, abuse-case testing, and impact analysis so false positives are reduced and priorities are clearer.
Do you provide remediation support and retesting?
Yes. Lex provides remediation guidance and can retest fixes for critical and high-severity findings.
