EventSentry File Monitoring

Overview

EventSentry File Monitoring is an on-premises file integrity monitoring feature for tracking changes across Windows devices. It suits administrators who need detailed change records, alert routing and centralized comparison, especially where PCI requirement 11.5 matters. Its central limitation is that it does not identify who made a change.

Key features

Monitoring covers additions, removals, size and SHA-256 checksum changes, as well as transaction-log tampering. That range helps teams spot unexpected modifications, while support for PCI requirement 11.5 makes it relevant to compliance work. It is less suitable when investigations depend on assigning each change to a person.

File records can include digital certificates and entropy, which can help detect certain ransomware outbreaks. Changes can be written to the Application event log with customizable severity and include previous and new sizes or checksums. That gives administrators useful context for assessing a change, but not the identity of its author; attribution is planned for a future release.

Monitored-file status can be consolidated in the EventSentry database for comparisons across computers. Alerts and integrations can reach email, MSSQL, PostgreSQL, MySQL or Oracle databases, HTTP(S), Syslog, SNMP traps and executable processes. This flexibility is useful for teams with established notification or reporting paths.

Exported event logs can be cryptographically signed and timestamped to help detect tampering. Database access can be limited to the local host, and EventSentry service users lack permission to delete or modify data. On Windows, BitLocker can protect the database at rest. These controls strengthen the integrity of stored records, though they do not replace change attribution.

Pricing

EventSentry Light is free and covers monitoring for 5 machines, basic log monitoring and community support. It has no SIEM capability or dashboards, making it a constrained starting point rather than a full deployment for teams that need those functions. EventSentry costs 85.00 USD per once, billed per Windows device, with a perpetual license, no data limit, on-premise deployment and phone/email support. The full edition also includes getting-started assistance. A 30-day trial is available.

The paid license is a one-time charge per Windows device rather than a recurring subscription, which may suit organizations planning long-term on-premise use. The free edition’s five-machine cap and missing SIEM capability and dashboards are meaningful limits for larger or more centralized monitoring needs.

Platforms

Deployment is on premises, and agentless monitoring is not supported. The supported Windows versions range from Windows NT 4 SP6 through Windows 11 and include Windows Server releases through Server 2025. Although the platform listing also names Linux, macOS and web, the supported-version list is Windows-specific; teams should assess that distinction before planning coverage outside Windows.

Who it's for

EventSentry serves a broad customer base, from individual users and consulting firms to government agencies, universities and Fortune 500 corporations. Its broad change coverage, configurable alerts and cross-computer database comparisons make it a strong fit for administrators who need centralized integrity monitoring and operational control. Teams that require a record of who changed a file should look elsewhere until attribution is available.

Pros and cons

• Pros: Tracks several important file and transaction-log changes, with optional certificates and entropy for additional investigative context.
• Pros: Sends alerts to a wide range of systems and consolidates monitored-file status for comparison across computers.
• Pros: Signed, timestamped exports and restricted database permissions help protect records from tampering.
• Cons: It does not currently report who made a change, limiting accountability in investigations.
• Cons: The free edition stops at 5 machines and omits SIEM capability and dashboards.
• Cons: No agentless monitoring means deployment requires more than simply polling devices remotely.

Alternatives

For a wider platform mix and a free entry point of up to 100 sensors and about 10 devices, consider Paessler PRTG Network Monitor. Choose Wazuh when a free, open-source, self-hosted option better fits your needs. Elastic Security is another freemium alternative for teams seeking a platform with Linux and self-hosted support.

OSSEC offers a free command-line option with core OSSEC rules and no dedicated support staff. Consider CimTrak Integrity Suite for a subscription-based integrity suite with endpoint-based bundles. FileAudit is a paid alternative with a free trial. ManageEngine ADAudit Plus has a free edition capped at 25 workstations and a 30-day trial. For a free, GPL-2.0 open-source option focused on file and directory integrity monitoring, consider Open Source Tripwire. Browse the File Integrity Monitoring Software directory to compare more options.

Verdict

EventSentry File Monitoring is a strong choice for administrators who want broad file-change coverage, flexible alert destinations and centralized comparison in an on-premise environment. Its one-time, per-device license and tamper-conscious record protections add practical appeal. Choose another tool if identifying the person behind each change is a requirement.
