A Square Group (ASG) Tech Stack

Government and enterprise modernization via cloud, security, and legacy systems engineering

IT Services and IT Consulting Catonsville, Maryland 51–200 employees Founded 2008 Privately Held

A Square Group (ASG) is a 51–200-person government and enterprise services firm built around mainframe, cloud infrastructure, and cybersecurity modernization. The tech stack reveals deep legacy systems expertise (z/OS, RACF, Assembler, Parallel Sysplex) paired with modern cloud (AWS, Azure, Kubernetes) and observability tooling (Splunk, Netcool, SolarWinds) — a pattern typical of firms managing federal mission-critical environments. Project inventory (satellite comms engineering, zero-trust automation, monolith-to-microservices decomposition, CI/CD shift-left security) and pain points (24/7 uptime, compliance, decommissioning integration) suggest ASG is primarily a government services vendor executing multi-year modernization and sustainment contracts.
