Trio’s FileVault support for macOS has been improved to provide more consistent, policy-driven enforcement of full-disk encryption across managed devices.

While FileVault enforcement was previously available, this update refines how FileVault settings are configured and applied through dedicated macOS security profiles, improving reliability, visibility, and administrative control.

What’s improved

• More structured FileVault configuration via macOS profiles

• Clearer separation between encryption policy definition and device assignment

• More predictable enforcement behavior across enrolled Mac devices

What FileVault does (technical overview)
FileVault is macOS’s native full-disk encryption technology. It encrypts the entire system volume using XTS-AES-128 encryption with a 256-bit key, ensuring that data stored on the device remains protected when the system is powered off or compromised.

Once enabled:

• User data, system files, and application data are encrypted at rest

• Access to disk contents requires authenticated user credentials

• Data remains unreadable if the device is lost, stolen, or accessed outside the operating system

Why FileVault is essential on macOS
macOS devices are commonly used in mobile and remote work environments. Without full-disk encryption:

• Data can be accessed by removing the disk or booting into external environments

• Lost or stolen devices pose a direct data exposure risk

• Compliance with security and data protection standards may not be met

FileVault addresses these risks by enforcing encryption at the storage layer, independent of user behavior.

How Trio applies FileVault
With this improvement, Trio enables administrators to:

• Enforce FileVault through centralized macOS profiles

• Assign encryption requirements consistently across device groups

• Maintain alignment with organizational security baselines for data-at-rest protection

Encryption state is derived from system configuration and device reporting. Encryption progress, key escrow workflows, and cryptographic validation depend on macOS platform behavior and are not actively inspected by Trio.

This update strengthens macOS data protection by making FileVault enforcement more consistent, manageable, and policy-driven within Trio.
