Is SIPWISE really this easy to hack?

Prospect just wrote me, “We are looking to setup a SIP Trunk in two locations in the US for customers running our PBX. We have trunk interop finished with two phone carriers – was running SIPWise but was hacked.”

Anyone out there know if SIPWISE is really this easy to hack?

Guess they have nothing like sipPROT to keep the gremlins at bay.
