It built a system called Go Mobile to provide secure communications, training, and collaboration applications to mobile soldiers. DISA recently decided to add Android and iPhone to the list of approved devices because of high demand from users. Unfortunately, this choice has become a giant pain in the flank. Why? Because both Apple and Google refuse to give DISA access to their security APIs."
