Identify security weaknesses
before they are exploited.
Web applications are a common target for attackers due to their exposure, complexity, and direct access to sensitive data or business workflows.
Packet33 provides web application penetration testing to help organizations identify vulnerabilities, misconfigurations, and logic flaws that attackers could exploit through the browser or API.
Our approach combines manual testing with targeted automation to uncover real security issues that scanners alone cannot detect.
Most incidents happen in
places scanners miss.
Modern applications consist of multiple layers including authentication, authorization, APIs, user workflows, session handling, and business logic. Many security incidents occur because of mistakes in these areas, not just technical vulnerabilities.
A proper web application penetration test provides assurance that your application can withstand real-world attack techniques.
- SOC 2 readiness and annual security testing requirements
- Supporting customer security reviews or vendor questionnaires
- Launching new features or major releases
- Protecting sensitive or regulated data
- Identifying business logic issues and abuse scenarios
- Validating fixes after past vulnerabilities
every layer of your application.
Authentication and session management
- Login and password reset workflows
- MFA implementation
- Session token handling
- Persistent sessions and session fixation
Authorization and access control
- Horizontal privilege escalation
- Vertical privilege escalation
- Unsafe role-based access controls
- Insecure direct object references
Input handling and injection attacks
- SQL injection
- Command injection
- Server-side template injection
- Insecure user input sanitization
Business logic and workflow abuse
- Bypassing required steps in workflows
- Manipulating pricing or billing logic
- Unauthorized access through flawed logic
- Circumventing feature restrictions
API testing
- Endpoint authorization
- Parameter manipulation
- Mass assignment vulnerabilities
- Data exposure in API responses
File handling, rate limiting and more
- Unsafe file upload validation
- File inclusion vulnerabilities
- Rate limiting and brute-force protections
- Error handling and information leakage
with your engineering team.
Scoping and access setup
We identify the application environment, user roles, and areas of concern. Test accounts are created for safe and controlled assessment.
Testing and vulnerability analysis
Manual interaction with the application, targeted automation, and attempts to manipulate workflows or data paths.
Reporting and remediation guidance
A structured report with severity ratings, reproduction steps, screenshots, and recommended fixes.
Retesting
Optional retesting once vulnerabilities are resolved to confirm fixes are effective before sharing reports with customers or auditors.
What you receive in every engagement.
- Full technical report
- Executive summary for stakeholders and auditors
- Risk ratings for each issue
- Reproduction steps and screenshots
- Remediation recommendations
- Optional retest
What a pentest helps you achieve.
