Dear teachers, dear users,
Is it possible to say so "to protect online business [here I'm trying to avoid the repetition of "website"] against (from?) unauthorized access"?
Thank you very much for your help.
Yes, if it's relevant in the wider context.
Rover_KE, thanks a lot!
You're welcome, but you don't need to thank me in a separate post.
Your Like is good enough for me (and for anybody else).
