Good examples that are similar would be ncircle and qualys VA appliances
which operate according to #2.

Maybe I should have listed the potential disadvantage of SaaS as it
would appears the external position only allows it to scan Internet-
facing websites. There are SaaS-based website VA offerings, WhiteHat
Sentinel included, capable of supporting non-Internet-facing systems
such as in development and staging environments. This is achieved in two
possible ways.

1) Allow the SaaS offering IP-ranges through the firewall and/or route
them to the eventual destination.

2) Appliance proxy. Install a device behind the firewall, which then
connects out to the SaaS infrastructure thereby establishing a outside-
inside traffic conduit. Whatever the proxy is allowed to access, so can
the SaaS offering.

Both options are already fairly common in the managed security services
markets, IDS/IPS and network vulnerability scanning for example.
