Latest Security Update from Apple

I have a perfectly good 15' MacBook Pro (Mid June 2010) running High Sierra (which I understand cannot be updated) - is there a way to apply the latest security update?

If you want added security both Malwarebytes and Avast offer continued updates to security that can help systems running High Sierra.
