File Integrity Monitoring (FIM)

Detect unauthorized file changes across Linux and Windows servers in real time.

Logchase FIM continuously monitors critical files and directories, detects unauthorized modifications, and alerts security teams before incidents escalate.

What is File Integrity Monitoring?

File Integrity Monitoring (FIM) is a security control that detects changes to files, directories, and system configurations.

It helps security teams identify:

  • Unauthorized file modifications
  • Malware or webshell deployment
  • Configuration changes
  • Privilege escalation attempts
  • Insider threats
  • Ransomware activity

Logchase FIM provides real-time visibility into file changes across Linux and Windows systems using lightweight agents.
