File Integrity Monitoring (FIM) continuously watches critical files, folders, configurations and registry keys, and alerts when they change unexpectedly. Because tampering, malware and misconfiguration all leave a change on disk, FIM is an early-warning system for your most important systems.
The tell-tale change
When an attacker plants a web shell, a rootkit alters a system file, or a bad change breaks a server, the common signal is a file that should not have changed. FIM turns that signal into an alert.
A named compliance control
FIM is a named requirement in PCI DSS and a core expectation of ISO 27001 and KVKK change-control. Auditors ask for it specifically.
