I only recently learned that telecom giant MCI bought managed security services provider NetSec for $105 million. Other telecom companies might want to look at Lisa Phifer's Managed Security Service Provider Survey or Adam Stone's In MSSPs We Trust for acquisition candidates. I expect acquisitions to continue, as there are between one and two dozen small MSSPs available. There are also people like myself who know how to build MSSPs from the ground up (hint hint). :)
Update: It must be confusing to work for NetSec. One minute you're working for MCI, the next you're working for Verizon!
