Mobile devices are the main development platform today, but testing these applications is becoming increasingly challenging.

The hacking of a mobile device can often be traced back to a vulnerable application. Vulnerability testing takes into account a number of factors in addition to the application being tested, which is why it is worth and necessary to run such a test on both Android and iOS operating systems.
