Note: Installing CrowdStrike AntiVirus also installs the PEAS Menu, which gives you information on CrowdStrike and Forescout

Encrypting your Mac

Any Mac that is enrolled in PEAS will prompt you for encryption on reboot if you are not encrypted. Depending on your version of the Mac operating system, it will ask when you log out, or log back in.

1. To determine if you are encrypted, open System Preferences, and click Security & Privacy

2. With FileVault selected, you will be able to see your encryption status:

    • When FileVault is set to on, then your computer is encrypted.
    • If FileVault is off, then your computer is not encrypted.

3. If you are enrolled in PEAS, it is recommended that you reboot, and when prompted, click Encrypt. Upon reboot, you will see this window:

4. Click Enable Now to begin the encryption process.
