Oddly enough, GTE Cybertrust doesn't actually seem to be the same Cybertrust that Verizon Business bought in 2007 (as information on "GTE Cybertrust" predates the incorporation of "Cybertrust" by a good ten years).

It looks like GTE Cybertrust was part of GTE Internetworking, which would have been absorbed into the Bell Atlantic-GTE merger which created Verizon.

That seems odd.
