nano SIEM vs Wazuh

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.

Wazuh unifies XDR and SIEM to analyze security data across endpoints, clouds, and networks for threat detection, incident response, and compliance work. Its rules identify errors, misconfigurations, malicious activity, and policy violations in operating system and application logs. File Integrity Monitoring tracks changes to content, permissions, ownership, and other file attributes. Vulnerability detection compares endpoint software inventories with updated CVE databases. Built-in active responses can take countermeasures, including blocking network access from a threat source. Wazuh can monitor AWS, Microsoft Azure, Google Cloud, Microsoft 365, and GitHub services, virtual machines, and activity. Its integrations guide also covers Elastic Stack, OpenSearch, Splunk, and Amazon Security Lake. Default rulesets provide mappings for PCI DSS, HIPAA, NIST 800-53, TSC, and GDPR, but those mappings do not themselves certify compliance. Wazuh runs on API, Linux, macOS, self-hosted, web, and Windows platforms. Its self-hosted open-source plan is free; paid plans start at $571 a month, and a 14-day trial is listed. Agents support Linux, Windows, macOS, Solaris, AIX, and HP-UX and require an average of 35 MB of RAM.
