Web Application Penetration Testing

Now that perimeter network security is more evolved, web applications are being targeted as one of the weakest links.

NetSPI identifies vulnerabilities in the network, system and application layers of a web application that allow us to elevate user privilege, manipulate data, and gain access to restricted functionality or data. We manually verify all exploitable and significant vulnerabilities.

During our web application penetration testing service, NetSPI will evaluate your web application for security vulnerabilities, and provide actionable guidance for remediating the vulnerabilities and improving your organization’s application risk posture.

We Test Web Application Security For:


  • Injection
  • Broken authentication
  • Sensitive data exposure
  • XML external entities (XXE)
  • Broken access control
  • Security misconfiguration
  • Cross-site scripting (XSS)
  • Insecure deserialization
  • Components with known vulnerabilities
  • Insufficient logging & monitoring

Thick Client Penetration Testing

Thick client applications house large amounts of sensitive data. NetSPI uses multi-vector testing to identify design and configuration weaknesses.

NetSPI’s approach to thick client risk assessments includes reviewing server-side controls, data communication paths, and potential client-related issues.

NetSPI tests the security between the server and client to identify communication or encryption vulnerabilities in order to provide clients with a comprehensive understanding of their application security posture and how to improve it.

For applications that are hosted, or use cloud services, NetSPI has an additional set of tests to ensure the application deployment and cloud environments are secure.

We Test Thick Client Security For:


  • Network transmissions
  • Client-side injection
  • Backdoors
  • Data storage
  • Improper error handing
  • Server-side controls
  • Strong authentication
  • Information leakage
  • Parameter manipulation
  • Least privilege authorization
  • Data protection in transit
  • Client-side cryptography storage

Mobile Application Penetration Testing

The pressure to quickly get a mobile app to market can lead to weak security and a lack of penetration testing.

NetSPI identifies vulnerabilities in your mobile application infrastructure that make your organization susceptible to an external or internal threat.

NetSPI will pentest your mobile application on Android and/or iOS for vulnerabilities. We’ll evaluate the target application from the perspective of both anonymous and authenticated users.

We manually test for security controls in four essential areas: file system, memory, network communications, and GUI.

We Test Mobile Application Security For:


  • Insecure data storage
  • Client-side injection vulnerabilities
  • Data flow issues
  • Weak server-side controls
  • Poor authentication and authorization
  • Side channel data leakage
  • Insufficient transport layer protection
  • Improper session handling
  • Cryptography
  • Sensitive information disclosure
