The mobile app security testing market continues to grow as the number of mobile app downloads increases, resulting in a higher risk of hacker attacks, fraud, and malware infections. To mitigate these risks, developers need effective mobile app security testing tools that can help identify vulnerabilities and provide recommendations for fixing them. When choosing a mobile app security testing tool, it's essential to consider factors such as deployment options, automation capabilities, and add-ons. Paid features like on-demand security tests and pen testing can offer added value, while free and open-source tools can be useful for small teams with limited resources. Some popular mobile app security testing tools include AppSweep, QARK, App-Ray, Data Theorem by Mobile Secure, NowSecure Platform, and Bitrise. These tools offer various features such as continuous monitoring, automated testing, and report generation, and some integrate with DevOps toolchains like Bitrise to streamline the development process.
