OutSystems AppShield, an additional cost add-on, automatically adds additional layers of security during deployment to make applications more resistant to intrusion, tampering and reverse engineering. AppShield makes it more difficult for attackers to spoof your app, tamper with its security controls, inject malicious code, run in an insecure environment such as on a rooted (Android) or jailbroken (iOS) device, and perform other malicious activities–securing your mobile apps both at rest and at run time.
