You can just at the company website to your bookmarks ... or as your startup favorite webpage ... or at it to your TOP SITES.
Safari is not a browser that you have to confirm if that is a trusted website.
You decide for your self if you like to bookmark it yes, or no ... as every bookmark you saved until now.
Sorry for this ... but I think I gave you the wrong idea to at a trusted website.
Read in this link I posted for you how to do it.
Good luck ...
