Jailbreaking a device exposes it to various security risks, such as malware, data theft, network attacks, and service disruption1234. Running an antivirus and enabling encryption may not be enough to remove the threats and restore the device's functionality. Undoing the jailbreak may not be possible or effective, depending on the method used. Backing up the files and doing a system restore may preserve the jailbreak and the associated problems. The best option is to erase the device and reinstall the original operating system that is compatible with the corporate policies and standards. This will ensure that the device is clean, secure, and compliant25.
