A company-owned mobile device is displaying a high number of ads, receiving data-usage limit notifications, and experiencing slow response. After checking the device, a technician notices the device…

Running an antivirus and enabling encryption might address some symptoms but does not fully reverse the security implications of a jailbreak, as the underlying operating system integrity is compromised.

A jailbroken device is inherently compromised and violates corporate security policies, making it unsafe for company data. Restoring the defaults and reimaging with the corporate OS ensures that all unauthorized modifications, potential malware, and vulnerabilities introduced by the jailbreak are completely removed, returning the device to a trusted state.

Backing up files from a compromised device is risky as it could propagate malware, and a system restore might not fully remove all traces of the jailbreak or malicious software.

Undoing a jailbreak can be complex and may not fully restore the device's security integrity, nor does it guarantee the removal of all associated malware; enabling antivirus is a partial solution.
