Andreas,

I think there are a lot of people on this list that would argue with that
statement.  As was mentioned earlier, AT&T, Verizon, and several others
including Verisign have very ample networks capable of handling attacks just
as large as Prolexic, if not bigger.

One thing to note about Prolexic, where it stands out from some of the
others is that it is a completely off-net solution.  Many of the other
offerings from folks like Verizon require you to have WAN circuits connected
to their network in order to avail of such a service (in other words, they
will only scrub that which would normally traverse their network on it's way
towards your WAN interface).

Others like Verisign have (smartly) adopted a similar model to that of
Prolexic.  They understand that requiring a physical connection into a
provider's cloud is a monolithic approach (and certainly runs counter to
today's mantra of offering up cloud-based services).


but... often the cost of scrubbing includes the cost of transit
to/from the remote provider, which is why 'cheapest' only counts for
an entire process, NOT for 'lookie, I bought the service!'.

either way, folks will learn one way or the other which works for them.
