Sophos Home for LGfL schools.
All you need to get started is a school email.

LGfL schools are being offered the use of Sophos Home antivirus software free of charge as long as you remain an employee of your school. This solution protects up to 10 computer devices (PCs or Macs) within each employee household. For support with installation or the product, you can visit https://home.sophos.com/landing/commercial-use

Please note: You must use your school email address here, even though you may then use the licenses on your personal devices.

If your school email is not recognized but you work at an LGfL school, email sophos@lgfl.net and we will add your email domain to the list.
