There is a well known german phrase:
Dafür stehe ich mit meinem Namen
Which indicates, that a person or company promises quality of his/their product. And to underline it, they guarentee this with the good name. It's tough to explain, but I hope you get it.
Now I would like to know a phrase in English language, which is likely to be known and has this meaning.
The direct translation doesn't sound right to me:
This is what I stand for with my name.
