Analysts function similarly to a Tier 1/2 SOC analyst with enhanced threat intelligence responsibilities, and are expected to independently research cyber activity, rapidly assess and evaluate available information, develop defensible analytical conclusions, identify gaps, and recommend appropriate follow-on actions while maintaining strong coordination with government and private sector partners. This position will support one of our Government clients in Arlington, VA.
