nano SIEM vs NetWitness Platform

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.

NetWitness Platform is a threat detection, investigation, and response platform for complex IT and OT environments.
