What It Is

Samhain, provided by Samhain Labs, is an open-source host-based intrusion detection system (HIDS) focused primarily on host integrity monitoring and detecting signs of compromise. It supports file integrity checking, log file monitoring/analysis, port monitoring, and detection of abnormal SUID executables and hidden processes. The project also offers Beltane, a web-based centralized management console for Samhain.

Core Capabilities

In terms of protection type, Samhain covers host-side security monitoring and is especially suited for detecting file tampering, suspicious processes, programs with abnormal permissions, and security events in logs. Deployment is flexible: it can run independently on a single host or use a client/server model to centrally manage logs and maintenance across multiple hosts, even across different operating systems. Beltane allows administrators to browse client messages, acknowledge events, and centrally update the file signature database. However, Beltane requires an existing Samhain client/server environment, a centralized signature database, and SQL database logging to be enabled, meaning deployment and maintenance are not entirely barrier-free.

Pricing and Support

The main content indicates that Samhain is open-source software, but it does not disclose commercial licensing, subscription pricing, or payment methods. For installation or maintenance support, the website recommends contacting Samhain Services for commercial support. The project also provides a user manual, FAQ, HOWTOs, user forum, mailing list, announcement list, and bug submission channels.

Pros and Cons

Its strengths are its focused and practical feature set, covering key areas of host security such as file integrity, logs, ports, SUID, and hidden processes; support for centralized management, making it suitable for multi-host environments; and its open-source nature, which makes auditing and self-managed control easier. Its drawbacks are that the site does not show enterprise security operations capabilities such as compliance certifications, SLAs, modern alerting channels, APIs, or SIEM/SOAR integrations; Beltane’s reliance on SQL and a central server also increases deployment complexity.

Who It’s For

Samhain is better suited for security teams, system administrators, and organizations with Linux/Unix or server operations expertise that need to build their own HIDS/file integrity monitoring. Teams looking for an out-of-the-box, cloud-native managed solution with strong visualization and rich integrations may need to evaluate alternatives such as Wazuh or OSSEC.

Access in China

Based on the crawled content, it is not possible to determine the stability of access from mainland China, so it is currently marked as unknown.
