If the aim is to filter active content from SSL. Which in many contexts
is okay - many of our clients severely restrict browsing in any case,
SSL or not. They are not trying to protect the users (who are supposed
to be working, not surfing the net) - they are trying to protect their
network.

But if your firewall is checking the data that is going through the
tunnel to ensure it is matching the expected protocol, then such
tunneling is much harder to exploit.

And these tunneling exploits are yet another reason why restricting SSL
usage may be a Good Thing to some organisations.

A good firewall will be doing the former too. And I've never personally
seen software that claims to be 100% secure on the packaging.
