BYOD Restrictions & Strategies for 2025
Blog Series
BYOD Restrictions
As organizations continue to embrace Bring Your Own Device (BYOD) strategies, ensuring security without compromising user experience remains a challenge. This post outlines a minimum baseline for BYOD restrictions across iOS, Android, macOS, and Windows devices—providing a foundation for companies to secure personal devices while allowing employees the flexibility to work from their own hardware. While these recommendations represent best practices, they are not a one-size-fits-all solution. Each company has unique security needs, regulatory requirements, and risk tolerances, meaning these restrictions can be improved upon, debated, or modified to better suit different environments. The goal here is to establish a starting point for securing BYOD devices in 2025 and beyond while balancing security and usability.
iOS Restrictions for BYOD
In a Bring Your Own Device (BYOD) strategy, it is crucial to enforce security policies that balance user privacy with corporate data protection. For iOS devices, restrictions ensure that sensitive corporate data remains secure while maintaining a seamless user experience. Compliance checks in Jamf Pro help validate whether a device meets these standards.
Functionality Restrictions
The table below outlines key restrictions that should be applied to iOS BYOD devices to prevent unauthorized data access, improve security, and maintain compliance:
| Setting | Platform | Enforcement Level | Purpose |
|---|---|---|---|
| Encrypted backups | iOS | Enforced | Ensures device backups are encrypted, protecting corporate data from unauthorized access. |
| Limited ad tracking | iOS | Enforced | Reduces ad tracking to protect user and corporate privacy. |
| Users to accept untrusted TLS certificates | iOS, visionOS | Restricted | Prevents users from accepting untrusted security certificates that could lead to man-in-the-middle attacks. |
| Documents from managed sources open in unmanaged destinations | iOS | Restricted | Prevents corporate data from being shared with personal apps. |
| Documents from unmanaged sources open in managed destinations | iOS | Restricted | Stops unverified personal files from being imported into corporate apps. |
| Pasteboard respects managed/unmanaged document restrictions | iOS, tvOS | Enforced | Ensures clipboard data from managed apps cannot be pasted into unmanaged apps. |
| Unmanaged apps to read contacts from managed contacts accounts | iOS 12 or later | Restricted | Protects corporate contacts from being accessed by personal apps. |
| Sending diagnostic reports to Apple | iOS | Restricted | Prevents the device from sending potentially sensitive system reports to Apple. |
| Wallet notifications on the Lock Screen | iOS | Restricted | Protects corporate payment data from unauthorized access. |
| Control Center on the Lock Screen | iOS 7 or later | Hidden | Prevents unauthorized access to quick settings without unlocking the device. |
| Notifications history view on the Lock Screen | iOS 7 or later | Hidden | Hides notification history to prevent exposure of sensitive corporate information. |
iOS Compliance Smart Group
To ensure compliance, Jamf Pro Smart Groups dynamically track devices that meet the BYOD policy. The following criteria should be used to enforce compliance:
- Device Ownership Type is Personal (Account-Driven User Enrollment)
- Device Ownership Type is Personal (User Enrollment)
- Jailbreak Detected is No
These checks ensure that only personal devices enrolled through the proper user-driven methods are allowed access to corporate resources, while jailbroken devices (which pose a significant security risk) are automatically excluded from corporate access.
Why These Restrictions Matter
Implementing these restrictions helps maintain a strong security posture while allowing employees to use their personal iOS devices for work.
- Preventing data leakage: Managed data remains within corporate apps, reducing the risk of accidental or intentional data leaks.
- Enhancing security: Blocking untrusted certificates and disabling certain Lock Screen functions prevents unauthorized access.
- Ensuring regulatory compliance: Organizations handling sensitive data (e.g., healthcare, finance) must enforce these policies to comply with standards like GDPR and HIPAA.
By combining functional restrictions with compliance checks, IT administrators can confidently enforce security policies without compromising user experience.
With these policies in place, companies can enable BYOD securely, ensuring employees have the flexibility to use their personal devices while maintaining enterprise security.
macOS Restrictions for BYOD
