Hi Angliholic,

The context you provided will work with either “from” or “against”.

I had an alarm system installed yesterday in my house to protect my family from recent break-ins in the neighborhood.

Using sun block can protect our skin from sun burns and possible skin cancers. The from usage infers prevention.

Sun block offers skin protection against sun burns and possible skin cancers. “Against” suggests counter measure. That’s the best explanation I could give you..

Thanks, Goodman.
