5ironCyber is a managed security services provider headquartered in Franklin, TN, offering 24/7 Security Operations Center (SOC) services. The company focuses on managed detection and response (MDR), combining human analyst expertise with automated security platforms to monitor, investigate, and respond to cyber threats in real time. Their core service model operates as an outsourced SOC, eliminating the need for organizations to maintain and staff their own internal security operations. Analysts monitor customer environments continuously, leveraging threat intelligence, automation, and machine learning to identify and triage alerts. 5ironCyber offers several managed security solutions: MDR+ for enhanced network visibility and active threat detection; endpoint security via managed EDR platforms; email security for identifying and blocking email-borne threats; and edge security designed to protect hybrid workforces across users, applications, devices, and locations. The company serves organizations across multiple verticals including financial services, healthcare, manufacturing, wholesale and retail, and education, with compliance and regulatory adherence cited as part of their value proposition in regulated industries. Their operational approach emphasizes active containment and response rather than alert-only notification. When a threat is detected, analysts take direct action to contain it, coordinating with the client's internal team when remediation extends beyond the SOC's reach. 5ironCyber has been listed on the Inc. 5000 ranking of fastest-growing private companies for four consecutive years as of 2025.
