In their own words
nano SIEM
nano SIEM is an AI-powered security information and event management product for security teams handling detection, alerting, investigation, and response. It stores security logs, OpenTelemetry traces, and metrics together for queries through nPL, its single query language. The maker says it can search billions of events in under a second using ClickHouse. Its pivt assistant can generate parsers, queries, detection rules, and investigation summaries from natural-language prompts. Detection rules support MITRE ATT&CK mapping, entity risk scoring, and tracking rare or first-seen indicators. Ingestion options include HTTP, Syslog, HEC, and Vector; listed parsers cover Palo Alto, CrowdStrike, Okta, AWS CloudTrail, Microsoft Defender, and Zeek. Deployment choices include managed service and BYOC, while Enterprise lists cloud, on-premises, and air-gapped deployment. The engine is open source under AGPL-3.0 and can be self-hosted without an account or bill. Hobby is listed at $26.00 per month, billed $204/yr, with 2 GB/day ingest and three team members.
Vigil
Vigil is a self-hosted SIEM that collects endpoint events, evaluates Sigma detections in real time, and returns structured JSON for AI agents. It runs on Linux, macOS, and Windows, or as a self-hosted service, without requiring a cloud account. Its single binary collects Windows Event Logs or Linux journald and sends batches every five seconds; short-lived enrollment tokens support secure agent onboarding. Vigil includes 41 Sigma rules covering 10 MITRE ATT&CK tactics. Its HQL query language searches event history with aggregations, timelines, endpoint filters, time ranges, and field values. The CLI pauses destructive actions until a person approves them. Vigil Connect extracts selected fields and the untouched raw alert from alerts; it supports Wazuh and Elastic, with Splunk and Microsoft Sentinel listed as coming soon. The Claude Code integration uses npx @vigil/skill and needs no MCP server or running process. The Apache 2.0 open-source plan is free and includes unlimited events. Enterprise support includes a dedicated Slack channel, custom integrations and SLAs, and a SOC 2 report.
