"Lockheed Martin, Northrup Grumman and Raytheon" You'll recall were in attendance at the August 2017 Washington D.C. day long, DOD contractors, simulated cyber attack exercise. SFOR defensive software, allowed in by DISA, was the only one used. As Zpaul posted, both Bo Dietl and Mark Kay were there to introduce it & guide participants in its use. The Gallagher deal proves it passed that critical "try before buy" exercise with flying colors that day. In 2019 it secures the entire DOD procurement cycle!
