In their own words
OpenNMS
OpenNMS is an open-source platform for monitoring faults, performance, traffic, and alarms across local and distributed networks. Horizon is the free community distribution with the newest features; Meridian is the stable subscription version. Data collection supports SNMP, JSON, WinRM, XML, SQL, JMX, SFTP, FTP, JDBC, HTTP, HTTPS, VMware, WS-Management, and Prometheus. Traffic monitoring handles NetFlow v.5/9, IPFIX, and sFlow, with stated capacity above 300,000 flows per second. Minions extend monitoring to remote devices and services, including locations behind firewalls or NAT through ActiveMQ or Apache Kafka. Integrations include email, Slack, Mattermost, scripts or webhooks, Jira, Remedy, TSRM, Grafana, and a REST API. Grafana views can show alarms, outages, KPIs, NetFlow, and data from multiple instances. The software supports API, Linux, self-hosted, and web deployments. Horizon is free; Meridian plans range from $6,000 a year to $66,000 a year, with larger deployments priced on request.
UTMStack
UTMStack is an open-source unified threat management platform that combines SIEM and XDR. It provides log management and correlation, threat detection and response, threat intelligence, alert investigation, file classification, SOC AI-powered analysis, and compliance capabilities. Its modules include vulnerability management, access-rights auditing, automated incident response, endpoint protection, dark-web monitoring, and file tracking. The platform correlates data during ingestion before indexing to support real-time detection and reduce alert noise. Deployment options include an ISO, Ubuntu installer, cloud SaaS tenant, virtualized environments, physical servers, and public-cloud virtual machines. Its v11 guide is designed for Ubuntu 24.04 LTS and also notes Red Hat support. The free trial is free; Essential costs $238.80 a month, billed monthly, and supports 25–50 devices on average with 150 GB HOT storage. Deployments above 500 data sources or devices require secondary worker nodes for horizontal scaling.
