Ostra Security provides a managed service that combines detection, response, and remediation across an organization's environment. It expands on traditional MDR and XDR by including incident investigation, containment, root-cause analysis, and remediation of underlying gaps. Through its managed platform, customers gain real-time visibility into detections, investigations, and remediation activity. The company serves lean IT and security teams and growing organizations that need enterprise-grade protection without building a full in-house security operations center. Based in Eden Prairie, Minnesota, and founded in 2018, it operates in the computer and network security sector. In August 2025, Ostra Security announced the acquisition of Blackwell Security, Inc., a move that expands its scale and capabilities.
