"Gov't Agencies, who are they" Answer is between the lines of the 5/31 PR "Pentagon to Install McAfee Security Software Worldwide in $550 Million Deal". The PR highlights first the DOD (first agency). Then it states "Coast Guard activities worldwide". The USCG falls under the DHS (second agency). It also mentions the US intelligence community which has several other agencies such as CIA, DIA, NSA.
Now recall McAfee's 9/14/17 PR on just the ARMY (Beta group) contract. Read the "Expected Capabilities and Outcomes Section". It states "advanced zero-day detection and countermeasures". Now what little cyber security company has the applicable patents that also has been working and playing well with McAfee (thank you Gold 49er &Zpaul for clearly showing that)? Can you say SFOR?
