The link between smartphone users and mobile apps is becoming stronger than ever. Every job, from getting up in the morning to going back to sleep, requires the use of mobile apps.  Moreover, mobile applications are becoming increasingly complicated, necessitating the installation of end-to-end security measures.

Enterprises may use mobile application security testing tools to create dependable apps that are scalable and available across numerous platforms. In this blog, we will evaluate mobile trends and take a look at some of the most promising mobile app security testing tools. 

What Numbers Tell Us About Mobile Apps:

  • Around 115 billion mobile apps were downloaded across the globe in 2019 (Sensor Tower)
  • In the year 2019, an average US resident spent three and a half hours on their mobile device
  • Around 120 billion hours are spent by users on mobile gaming apps in a year, get Apps download data.
  • The total number of apps downloaded on the Apple Store in 2019 - was 30.6 billion (Sensor Tower)
  • The total number of apps downloaded on the Google Play Store in 2019 - was 84.3 billion (Sensor Tower)
  • According to a forecast, in 2019, around $461 billion was generated in revenue through mobile apps (Statista)

  • In 2019, malware attacks on mobile banking apps also increased by 50% as compared to 2018 (DarkReading)

Imagine so much is happening in this ecosystem yet the privacy and security aspect of a mobile app takes a hit. More often it is replaced by the convenience and the time to market priorities of the business owners. So much time and money are devoted to other parameters such as Performance, Usability, Functionality, Compatibility, Load, etc.

The bad news is that securing mobile apps is not an easy affair. The added sophistication of the multiple mobile OS used nowadays makes the matter worse. But the good news is that there are several security testing of mobile apps available that are useful in the various aspects of mobile app security such as active threat monitoring, malware analysis, real-time security testing, etc.

6) Mitmproxy


Mitmproxy is a free open-source tool that allows users to intercept, inspect, modify, and replay any traffic flows exchanged between an app and backend services. The name itself is derived from a kind of cyber attack called MITM (Man in the Middle attack).

In the case of a MITM attack, the attacker secretly relays and possibly alters the communication between two parties who believe they are directly communicating with each other.

7) iMAS


iMAS is an open-source security testing tool that helps developers in encrypting application data, prompt passwords, prevent application tampering, and enforce enterprise policies on iOS devices.

Whether one needs to check for how ios jailbreak really works or debuggers, secure sensitive information in memory, or mitigate against binary patching, iMAS helps your iOS app protect itself in a hostile environment.

Last but not the least,  security is not a one-off thing. It's something that needs to be taken care of every single day. We hope these best 7 free mobile security testing tools help you in getting a head start with security.
