Ontinue is a managed security services provider specializing in Managed Extended Detection and Response (MXDR), with an exclusive focus on Microsoft security technologies. The company operates a 24/7 Security Operations Center (SOC) and delivers services built around Microsoft Defender and Microsoft Sentinel. Ontinue's core offering, branded as ION MXDR, combines detection and response capabilities with assessment and prevention services. The platform integrates artificial intelligence with human analyst expertise to identify and respond to cyber threats on behalf of customers. Services are designed to help organizations reduce risk, accelerate threat detection and response, and improve overall security program maturity. The company targets organizations seeking to outsource or augment their security operations function. Its service model is continuous, providing around-the-clock monitoring and response without requiring customers to manage their own SOC infrastructure. Ontinue holds several compliance certifications including SOC 1 Type Report, ISO 27001, ISO 27017, ISO 27018, and HIPAA, reflecting its commitment to information security management standards relevant to its customer base. The company operates globally with eight offices across North America, Europe, and APAC, including headquarters in Zurich, Switzerland and Redwood City, California. It employs over 290 people worldwide. Ontinue was formed following the evolution of Open Systems, with several members of its leadership team carrying over from that organization.
