EventSentry File Monitoring vs FIM

EventSentry File Monitoring tracks file additions and removals, size and SHA-256 checksum changes, and transaction-log tampering. It can gather digital certificates and entropy, which may help detect certain ransomware outbreaks. Changes can be logged to the Application event log with customizable severity and previous and new sizes or checksums. The current status of monitored files can be consolidated in the EventSentry database for comparisons across computers.

Notifications and integrations can go to email, MSSQL, PostgreSQL, MySQL or Oracle databases, HTTP(S), Syslog, SNMP traps, and executable processes. Exported text event logs can be cryptographically signed and timestamped to help identify tampering. EventSentry says its file integrity monitoring helps with PCI requirement 11.5. The full edition is an on-premise perpetual license listed at $85 per Windows device; EventSentry Light is free for five machines. A 30-day trial is listed. The feature is listed for Linux, macOS, web, and Windows, while the detailed supported operating-system list names Windows versions from NT 4 SP6 through Server 2025.

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.
