All I can say is KTLS was THE only defensive software used in last year's DOD Contractors' simulated cyber attack exercise. ACS's owner, Bo Ditel, was allowed to participate (in this invitation only exercise, (see the ACS PR about it) only after DISA review & approval of SFOR's software to provide the keystroke transportation layer security. This was a "Try before buy" type of exercise in accordance with the Pentagon's procurement policy guidance. KTLS must work well or ACS would not be promoting it so strongly on their website.
