Circles, a global digital telecom provider, transitioned from MSSP dependency to an in-house, automation-powered SOC using Graylog Security Cloud on AWS. With growing compliance demands, API coverage gaps, and high analyst fatigue, Circles needed full SOC visibility, fast deployment, and automation-friendly tools.

By implementing Graylog’s agentless ingestion, API-driven workflows, SOAR integration, and AI enrichment via Illuminate, the team built a scalable, cloud-native security operation that unified visibility across AWS, on-prem, and partner workloads.

What You’ll Learn in This Case Study:
  • How Circles replaced MSSP dependency with in-house SOC control
  • The benefits of agentless log collection and SOAR automation
  • How Graylog’s API-first design enabled full auditability and rapid response
  • Why Illuminate and pipelines cut false positives and analyst burnout
  • How Circles achieved SOC maturity and continuous compliance

Graylog empowered Circles to consolidate logs, automate triage, deliver real-time response, and meet enterprise-grade telecom security and compliance goals—without overwhelming its lean cyber team.
