EventSentry File Monitoring

EventSentry File Monitoring is an on-premises file integrity monitoring feature for Windows environments. It suits administrators who need configurable alerts, cross-computer comparison and compliance support. Its chief limitation is that it records file changes without identifying who made them.

Overview

Monitoring covers additions, removals, file-size changes, SHA-256 checksum changes and transaction-log tampering. That breadth helps teams spot unexpected changes across important files, and the product supports PCI requirement 11.5. But it is a weaker fit for investigations where accountability depends on knowing which user made a change.

The full edition is licensed per Windows device, so costs rise with the number of devices being monitored. In return, the license is perpetual, on-premises and has no data limit—an attractive model for organizations that prefer local deployment and predictable licensing over a recurring subscription.

Key features

File records can include digital certificates and entropy, which can help detect certain ransomware outbreaks. Changes can be written to the Application event log at a customizable severity and include previous and new sizes or checksums. That detail can help administrators assess what changed, though it does not close the attribution gap.

EventSentry can consolidate the current status of monitored files in its database for comparison across computers. Alerts and integrations can go to email, MSSQL, PostgreSQL, MySQL or Oracle databases, HTTP(S), Syslog, SNMP traps and executable processes. The range is useful for teams that need to route notifications into existing systems rather than rely on one destination.

Exported event logs can be cryptographically signed and timestamped to help detect tampering. Database access can be restricted to the local host, and EventSentry service users cannot delete or modify data. When the database runs on Windows, BitLocker can protect it at rest. These controls strengthen local record protection, but they do not identify the person behind a file change.

Pricing

EventSentry Light costs nothing and covers up to 5 machines, with basic log monitoring and community support. It has no SIEM capability or dashboards, so it is best for small deployments that need a no-cost starting point rather than the full monitoring feature set.

EventSentry costs $85, paid once, billed per Windows device. The perpetual on-premises license has no data limit and includes phone and email support. It is the relevant option for organizations needing the full edition, but device-based pricing means the total depends on deployment size. A 30-day trial is available.

Platforms

The supported platform list covers Windows NT 4 SP6 through Windows 11, plus Windows Server releases from 2000 through Server 2025. Deployment is on-premises, and agentless monitoring is not supported. Although the service is associated with Linux, macOS and web platforms, the full license is billed per Windows device; organizations should evaluate the stated Windows support before planning deployment.

Who it's for

EventSentry serves a broad customer base, including individual users, consulting firms, government agencies, universities and large corporations. It is most compelling for Windows administrators who value detailed change records, centralized comparisons, multiple alert destinations and PCI 11.5 support. Teams that require user-level attribution should choose a tool that provides it.

Pros and cons

• Broad change coverage: tracks additions, removals, size and checksum changes, and transaction-log tampering.
• Flexible alert routing: supports email, databases, HTTP(S), Syslog, SNMP traps and executable processes.
• Local data protections: signed and timestamped exports, restricted database access and optional BitLocker protection on Windows help guard records against tampering.
• No change attribution: teams cannot use EventSentry to determine who made a file change.
• Paid license scales by device: the $85, paid once price is per Windows device, which can make larger deployments more expensive.

Alternatives

File Integrity Monitoring Software is the broader category directory for comparing options. Consider Paessler PRTG Network Monitor if a freemium alternative with a 100-sensor free tier and broad platform support better suits the deployment. Wazuh offers a free, self-hosted open-source option, with a paid Small plan starting at $571 a month. OWASP Amass is a free, open-source framework for readers seeking a no-cost tool rather than a paid monitoring license. Elastic Security may suit readers looking for a freemium security platform. FIM is a free open-source alternative with no usage limits stated. Open Source Tripwire is a free GPL-2.0 option for file and directory integrity monitoring. OSSEC offers a free command-line option with core rules and no dedicated support staff. AIDE is a free GPL-2.0 alternative for self-hosted use.

Verdict

Choose EventSentry File Monitoring if you manage Windows devices and need broad file-change detection, centralized comparison and flexible alert delivery with local record protections. The perpetual, no-data-limit license is appealing for sustained on-premises use, but per-device pricing and the lack of change attribution make it a poor choice when identifying the person behind a change is essential.
