SanDisk Security
SanDisk Security is a macOS utility for password-protecting and unlocking supported SanDisk external SSDs with built-in hardware encryption.
What is SanDisk Security?
SanDisk Security is a desktop security utility for macOS that helps users protect supported SanDisk external SSDs with password-based access control. It is designed for people who carry portable drives and want to restrict access if the device is lost, shared, or moved between computers. The app lets you set a password on compatible drives, unlock protected drives, change or remove an existing password, and check drive firmware information from within the utility. It works only with specific supported SanDisk and WD-branded storage products that include the required hardware support, so it is not a general file-encryption app for every disk or folder on your Mac. The software was published by Western Digital for branded products and has since been replaced for ongoing support by newer SanDisk drive-management software.

Safety overview
Status: Mostly safe
This is legitimate drive-security software for supported external SSDs, and the access it needs to detect and unlock those drives is normal for its purpose. Its main practical risk is usability: if you forget the drive password, you may lose access to protected data until you follow the vendor's recovery or reset options for that device. Support for SanDisk Security ended on July 31, 2025, so users should avoid relying on it for new setups when a newer supported tool is available.
Recommendation: Keep SanDisk Security if you still use a compatible password-protected SanDisk drive and need to unlock or manage it on your Mac. If you no longer use supported hardware, you can remove it. For ongoing use with newer supported drives, consider moving to the current SanDisk desktop app so you continue receiving supported workflows and updates.
