[Blue Cedar Enforce](https://cybersectools.com/tools/blue-cedar-enforce) Blue Cedar Enforce is a mobile application security product that provides runtime application self-protection (RASP) and data protection with on-device policy enforcement, including offline scenarios. The RASP component monitors and defends mobile apps against exploits and attacks in real time. It enables self-monitoring for suspicious behaviors and self-defense against techniques such as app tampering, hooking, injection, jailbreak/rooting, man-in-the-middle attacks, and unauthorized debugging. It continuously monitors memory, network traffic, and the file system to identify and block threats. The data protection component safeguards sensitive mobile app data through device-independent AES-256 encryption for locally stored data, protecting it even if the device is compromised. Device posture policies restrict app launch or foreground access unless requirements such as PIN locks or minimum OS versions are met. Additional controls include authentication, data loss prevention, and blocking of screenshot capabilities. The product is applied to mobile applications to add these protections at the app level.
