EventSentry File Monitoring vs Open Source Tripwire

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.

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.
