Atomic OSSEC vs FIM

Atomic OSSEC is an endpoint detection and response system that also protects cloud workloads and APIs. Its monitoring covers intrusion detection, file integrity, log management, active response, and vulnerability management. A GUI centralizes management of agents, servers, events, file integrity monitoring, rollbacks, and third-party integrations. The product lists more than 5,000 preconfigured OSSEC rules and out-of-the-box integrations for Splunk, ArcSight, ELK, and QRadar. It supports AWS, Azure, and GCP, and offers compliance reporting for frameworks including PCI DSS, HIPAA, NIST, GDPR, and CIS. Deployment can be on premises or cloud-based SaaS, including in air-gapped environments. The maker also describes support for legacy systems such as Windows, Linux, AIX, HP-UX, and Solaris, plus monitoring of operational technology without agents on sensitive equipment. A 14-day trial covers up to 10 licenses and does not require a credit card. The listed plan price is priced on request, pricing starts at $55 per agent, and bulk discounts are available; a separate pricing note says from $5/mo.

FIM is free, open-source software for monitoring file systems on premises. It watches files in the background, keeps historical information, emits events when changes occur, creates hashes, and analyzes content, attributes, ownership, and permissions. On Linux, the Audit daemon can identify who caused an event and which command produced it. Events may be written locally, sent over a network, or sent to both destinations. Documentation lists Elasticsearch 8.x or OpenSearch 2.x and Splunk indexer 9.x integrations, with only one integration active at a time. FIM runs on Linux, Windows, and macOS. Installation guidance lists Ubuntu Xenial or later, CentOS 7 or later, Windows 7 or Server 2016 or later, and macOS Big Sur or later. Minimum requirements are one CPU core, 128 MB memory, and 1 GB storage, with storage use increasing over time. The maker says support is free and provides an email contact.
