Best File Integrity Monitoring Tools

File Integrity Monitoring (FIM) is an essential layer of your network’s defense mechanism as it helps to identify unauthorized access and malicious activities across your critical files. This way, it reduces the chances of insider attacks and prevents any unwanted or accidental changes to essential documents and files.

Here is our list of the best File Integrity Monitoring (FIM) tools:

  1. SolarWinds Security Event Manager (SEM) – FREE TRIAL This centralized FIM tool has advanced log management features that track and analyze your file system’s access and display the results in an intuitive dashboard. Get a 30-day free trial.
  2. Datadog Security and Compliance Monitoring Continuously monitors files and their access and configurations to provide an additional layer of security for your organization.
  3. ManageEngine EventLog Analyzer Handles log management, auditing, and IT compliance to provide insights into potential threats, so you can stop them before they turn into a full-fledged attack.
  4. Netwrix Auditor Detects security threats, proves compliance, and increases IT efficiency.
  5. Qualys FIM A cloud-based tool that specializes in monitoring integrity violations across your entire network in real-time, so you can address issues before they spiral out of control.
  6. OSSEC A popular open-source intrusion detection system, and it also comes with advanced file integrity monitoring.
  7. Trustwave Endpoint Protection Another comprehensive cloud-based security solution that delivers integrated protection against malware and other attacks on file systems.
  8. Tripwire A FIM that does not only generates alerts but also provides actionable intelligence that would make it easy to address the issue.
  9. Samhain File Integrity This host-based intrusion detection system combines file integrity monitoring with log file monitoring and analysis to give you a comprehensive view of the state of security within your organization.

File integrity monitoring tools and practices significantly reduce shutdowns to a system by identifying the possible threats, so the same can be mitigated at the earliest.

Another advantage of implementing FIM within your organization is compliance. For organizations that store or process credit card payments, FIM is a mandatory requirement to comply with the Payment Card Industry Data Security Standard (PCI DSS). For other industries, FIM is a requirement for many different standards as well.

The easiest way to implement FIM within your organization is to use tools geared specifically for this purpose. And this is also a challenge given the many tools that are available in this space today. While choosing an FIM tool, make sure to run through its features to see if it’s a good fit for your organization. This is more important if you have hybrid environments, custom programs and operate on limited resources as you don’t want the FIM solution to take up all your resources.

Based on these aspects, we came up with the lightweight choices outlined above that work well across on-premises, cloud, and hybrid environments. Let us now explore the features of each of these tools to understand what is a good fit for your organization.
