API - Penetration Testing Pentesting

NetSPI evaluates target APIs across the entire stack to help your security and development teams inventory and evaluate APIs for security vulnerabilities. This comprehensive approach combines manual expertise with automated tools to identify vulnerabilities that can compromise your applications and data. Five key API pentesting focus areas include:

Web App Penetration Testing Pentesting

NetSPI uses commercial, open source, and proprietary tools to test your web apps for vulnerabilities.

""

Authenticated

Multiple credentialed users by role to elevate privileges, gain access to restricted functions, test auth logic issues, and more.

Anonymous

Non-credentialed user testing of web application and system layers, with multiple scanners, manual verification, and more.

OWASP Top 10

In addition to identifying application logic weaknesses, your web app pentesting service will target OWASP Web App Top 10 Vulnerabilities.

Web App Pentesting

NetSPI uses proprietary, commercial, and open source tools to test your web apps for vulnerabilities.

Mobile App Pentesting

NetSPI tests your Android & iOS mobile apps for vulnerabilities, including the OWASP Mobile Top 10, and mobile security controls across 4 essential areas:

  • Mobile App File System
  • Application Memory
  • Network Communications
  • Graphical User Interface

According to Gartner, “Organizations face the challenge of having many applications to test, but limited budget and resources to support manual penetration tests, resulting in visibility gaps. Major changes, newly released vulnerabilities and other exposures often remain untested until the next annual cycle."

Virtual Application Pentesting

NetSPI identifies the risks specific to applications published through virtualization platforms, as well as evaluates target virtual applications across the entire framework and application stack. Our approach identifies critical vulnerabilities including broken object-level authorization, function-level access control issues, unrestricted resource consumption, and security misconfigurations that could compromise your virtual apps.
