con- nections (and the data generated by these elements), is driving a natural shift toward edge operations. Booz Allen and SUSE RGS are at the vanguard of innovation in this space. Booz Allen has been insight instantly. This is in sharp contrast to earlier methods in which data was passed via an operations center, by which time the target may have moved or the environment altered. Outcomes have been
