I’d like to commend your attempt here, and not sound discouraging or anything like that. Personally though, I like the other design a little bit better. Like another commenter suggested, this design seems to evoke security more than privacy. The shield and lock seem to be pretty commonly associated with those other meanings already. The dove being inside the lock definitely seems to overcomplicate things a bit too.
That being said, I do think your coloration and black undertones look better though and overall there’s a bit more visual interest.
Ha, I like that last line ‘…looking forward to seeing you rage quit’
It seems like they’re doing it justice, and it looks like it will have a proper meaty feel to it
