If a company like Alert Logic is not answering questions, then you RUN FOR THE HILLS. The very idea that you would consider them now is a forgone conclusion. I certainly won't.
Also, when you use and acronym, define it before or after its use.
To me, because of my electronics background and even with work on many OSes from pre-PC to present SOC = System On Chip.
What types of security procedures should a SOC such as Alert Logic have to keep data safe?
