Application Penetration Testing
Application Penetration Testing
Find and fix hidden vulnerabilities in your application code before attackers do.
Your apps drive revenue and trust, yet hidden logic flaws and silent API gaps can turn them into an attacker’s easiest win. Packetlabs steps in as your guide with an OWASP‑aligned, 100% tester‑driven assessment led exclusively by OSCP‑certified penetration testers..
We map every route, break past the OWASP Top 10, and chain “mind‑bending” business‑logic exploits that scanners miss. Then, the moment each issue is found, we hand you a clear remediation plan to ensure you can release with confidence.
What's included:
Thorough mapping of in-scope pages and endpoints
Automated scanning and validation of findings
Manual discovery of up to 200 types of vulnerabilities across 10+ categories
Demonstrated impact to help with executive and developer buy-in
Comprehensive reporting with detailed step-by-step instructions to reproduce
Advisory on remediation steps and retesting to validate closure of findings

Application Penetration Testing Service Highlights
Configuration Management
Assess supporting infrastructure and application configuration for weaknesses
Authentication
Test for password policies and reset functionality
Error Handling
Ensure the application reacts appropriately to unwanted data
Identity Management
Assess account creation and enumeration possibilities
Input Validation & Client-Side
Test for insecure coding practices that could lead to injection attacks
Session Management
Test for weaknesses in the session management schema
Cryptography
Identify weaknesses for cryptographic attacks
Business logic
Prevent application misuse by ensuring business logic is secure within each flow
Authorization
Identify misconfigurations in the authorization schema to prevent privilege escalation
Which Application Pentest is right for you?
Not sure whether a standard web application pentest is enough or if a whitebox approach would provide better insights? The table below highlights the key differences to help you determine the best fit for your security needs.
Conventional Web Pentest | White-box Web Pentest | |
|---|---|---|
Scope | Focuses on assessing the web application from an external attacker’s point of view | Evaluates the application with full knowledge of the source code, configurations, and internal logic |
Testing Depth | Identifies visible vulnerabilities and common weaknesses | Finds deeper issues, such as logic flaws, insecure coding practices, and hidden security risks |
Approach | Simulates real-world attacks with minimal internal knowledge (blackbox/graybox) | Combines automated scanning, code review, and detailed manual testing to uncover issues that might be missed externally |
Common Findings | Common web vulnerabilities like broken session management, cross-site scripting (XSS), and business logic flaws | Hard-to-find vulnerabilities including authentication bypass, hidden backdoors, and insecure API integrations |
Ideal for | Routine vulnerability checks, security compliance, or external attack simulations | Organizations needing a thorough security review or a deeper risk assessment |
Reduce the risk of a breach within a web or mobile application.
By conducting Application Penetration Testing, you'll get:
Going beyond automated testing
Our extensive manual processes provide one of the most thorough services the industry offers.
Developing a threat model
We study the overall purpose, the components, and their interaction with sensitive information or functionality.
Protect proactively
We explore opportunities for more advanced attackers, mimicking a real-world scenario.
Detailed application security report
After a thorough analysis, we manually compromise each layer of defence within the environment to generate a detailed report.
