root9 is an Alert Management, On-Call, and IT service management (ITSM) platform for IT Operations, NOC, SRE, DevOps, Platform Engineering, and Infrastructure teams. It runs the full operational lifecycle on one foundation that learns from your operation itself, so alerts, incidents, changes, problems, requests, and on-call response all share the same operational identity, memory, and understanding. root9 provides alert management, event correlation, incident management, problem management, change management, service request management, on-call and escalation management, knowledge management, operational analytics, automation, and collaboration in Microsoft Teams and Slack. AI agents assist on every record, from incident investigation and change preflight checks to problem root cause and request fulfillment, with the evidence and reasoning shown so your team decides what happens next. Instead of a CMDB nobody keeps current, root9 builds operational identity from real activity through its Identity Correlation Database (ICDB): a self-building inventory earned by evidence, not maintained by hand. By combining alert data, response behavior, ownership, correlations, and operational history, root9 reduces alert fatigue, improves incident response, increases visibility, and uncovers the operational patterns that traditional monitoring and observability tools often miss. It gets sharper every time you use it. Built to learn, not to be taught. Works alongside Splunk, Datadog, Grafana, Azure Monitor, CloudWatch, New Relic, Prometheus, Dynatrace, ServiceNow, Jira, Microsoft Teams, Slack, and more, complementing your existing monitoring and ITSM investments.
