Well, it's not "secure", it's simply routing isolated.  If you want
security, as in encryption, you will need to do that on your own.

If you need low convergence times, MPLS/VPN is probably not your best
choice.  I don't know of many (if any) providers who will guarantee the
convergence times through their network.  You should expect convergence
times in the 10's of seconds or more for certain types of failures.

You may want to consider getting an L2VPN solution such as VPWS or VPLS and
running your own routing protocol and failure detection methods.
