Sophos Anti-Virus is licensed for use by current MIT faculty, staff, students, and affiliates for use on MIT-owned computers and a single personal computer per user.

How to Obtain


  • Licensed users may install software on one personal home computer.
  • Upon ceasing employment with MIT, faculty and staff members do not have the continued right to use this software and should delete it from their personally-owned machines.

Downloads (MIT certificate required)

  • Mac download (9.6.7)
    • macOS has a security feature called SKEL that blocks unauthorized kernel extensions like the one Sophos uses for on-access scanning. With the 9.6.7 installer, users will be prompted to go into System Preferences and authorize the extension. On computers enrolled in jamf | PRO, it will install correctly without extra user interaction.
  • Windows download (9.6.4)
  • Linux download (9.12.2 VE3.65.2)
  • Lincoln Lab available software (Lincoln Lab certificate required)


If you have other virus protection software installed, IS&T recommends that you remove it.


In the application, go to Help > Sophos Anti-Virus Help.

Note: Apple is no longer releasing security updates for OS X 10.6 and 10.7. IS&T does not recommend running computers with those operating systems on the network. We strongly encourage you to upgrade to the latest Mac OS to ensure that they are protected.
