  • IP/Data Protection

    The abundance of development tools, libraries, and educational materials available for a popular platform inevitably goes hand in hand with the abundance of decompilers, automatic crackers, and malware toolkits. The ease of IP theft and the ubiquity of the platform make Android apps an especially attractive target for malicious competitors and hackers.

    We can conduct a security audit of your Android applications and provide recommendations on protecting your intellectual property and your end users' data, so as to prevent losses from piracy and reputation damage.
