Security matters

This is a conference logo designed at the Boston Group for the NSA under Creative Director, Linda Pepe. It was a conference about international cooperation on terrorist-level security matters.
It seems I glean at least one lesson from every job. Account Service didn’t want to present it because the client had internal workgroups known as X-group, Y-group, etc. I insisted and finally prevailed, and this logo (which forced itself into my conscious mind while I was on the train) was chosen. Persistence generally pays off.
