Grep_Tribe Blue Team Shares SOC Defense Lessons from Standoff 17 Cyber Battle

The Grep_Tribe team participated in Standoff 17 for the third time, defending the RetailSTF Group infrastructure in a simulated State F environment against continuous red team attacks. They handled 37 confirmed incidents, 22 detected incidents, five investigated critical events, and maintained 88 percent average infrastructure availability. The team used familiar Positive Technologies tools alongside the new R-Vision SOAR platform to automate routine responses such as IP blocking and file sandboxing. Work was organized through a tribal system with role-based preparation and dynamic small-group investigations for complex attack chains. Participants highlighted how the event tested prioritization, Threat Intelligence attribution, and automation under high-intensity conditions unlike daily SOC operations. The experience reinforced plans to expand SOAR playbooks for repetitive tasks in their real internal SOC environment.
