There are similar boxes from FatPipe and Radware (and others) that
promise the same thing. I've done some light research on them and while
I can see some positives, I don't prefer them to our current solution.
My boss asked me to take a look at them, again, because he's concerned
that there's little BGP experience in our department apart from me and
he thought that might be one possible solution. It still may be but I
don't like the hoops you have to jump through to make these devices
work.

Then again, I don't have any practical experience with them and I hope
someone who has will chime in.
