Security review of Geo architecture

As part of making Geo "generally available", @kathyw offered to provide a security review of the Geo architecture.

Kathy, what do you need from the Geo team to conduct this review? The cutoff for code to make it into 10.2 is Nov 7th.

@briann Can you ask Recurity if they can do the whitebox test earlier? We plan on having Geo GA out in 10.2, but I assume we can ask them to look at a release candidate even earlier? Subsequently, I would expect / hope that their findings can help inform what we need to do in 10.3 to harden the feature.
