Open Source Tripwire vs Wazuh

Open Source Tripwire is free file and directory integrity-monitoring software for Linux, macOS, BSD variants, Solaris, AIX, HP-UX, Minix, Haiku, GNU/Hurd, and Cygwin. It compares the current filesystem with a known baseline and reports differences. A policy file defines monitored paths and checked attributes such as hashes, permissions, and ownership. Policy, configuration, and database files are signed by default, while reports may also be signed. Email reports are available when enabled in configuration. The project suggests scheduling periodic checks with cron, but its install script does not create those jobs. RPM, Debian, and make-based installation use a setup script for initial keys and policy creation. It runs on the user’s own system rather than as a managed service. Windows builds through Cygwin lack Registry monitoring and Windows-specific file attributes. The software uses GNU GPL version 2 or any later version. Separate commercial Tripwire products are also offered.

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.
