OpenText Enterprise Security Manager (ArcSight ESM) vs Wazuh

OpenText Enterprise Security Manager (ArcSight ESM) has no write-up on Specifiction yet; its figures are above.

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.
