What is a significant concern when employee smartphones are jailbroken?

When employee smartphones are jailbroken, a significant concern is the access to restricted corporate data. Jailbreaking removes the built-in security restrictions imposed by the device's operating system, making it easier for malware to infect the device and for unauthorized apps to access sensitive information. This situation can lead to data breaches, as sensitive corporate resources, such as email, files, and secure applications, may be exposed to risks that would typically be mitigated by the device’s security controls.

Furthermore, employees may install applications from untrusted sources, which can further compromise corporate data security. Organizations often implement stringent security policies around mobile devices, and a jailbroken smartphone is inherently non-compliant with those policies, exposing the organization to heightened risks. Thus, maintaining the integrity and confidentiality of corporate data is critically undermined when smartphones are jailbroken.
