Title: Solid full-disk encryption, but showing its age (10.5.1)

Broadcom Support Portal: Log in to your account and navigate to My Downloads. Search for "Symantec Encryption Desktop" or "PGP Encryption Desktop".

  1. Dig out an old Windows 7 or macOS 10.12 (Sierra) machine – 10.5.1 won’t install on Windows 11 or macOS Ventura+.
  2. Find a verified SHA-256 hash of the original ISO (e.g., Symantec_Encryption_Desktop_10.5.1_MP1_Win64.iso). Search Broadcom’s old KB articles for checksums.
  3. Run the installer in an air-gapped VM first — test with EICAR files to ensure it’s not tampered.
  4. Use your existing license key (10.5.1 keys don’t expire, but activation might fail — offline mode works).

Managed: Requires a customized installer created via the Symantec Encryption Management Server .
