What it is

Proof of integrity.

FIM (File Integrity Monitoring) establishes a baseline fingerprint of your sensitive files and configurations, then detects any deviation — an unexpected addition, change or deletion.

Positioned on the Detect function of NIST CSF 2.0. Integrated and operated by our experts, with market-leading technologies.

Key capabilities
  • Baseline fingerprint of critical assets
  • Continuous deviation detection
  • Qualified alerts on suspicious changes
  • Compliance evidence (PCI DSS)

What FIM delivers

Monitor, compare, alert.

Immediate detection of any tampering with your sensitive assets.

File integrity monitoring

Continuously check the state of your sensitive files and directories.

Change detection

Spot any addition, change or deletion against the baseline.

Critical files & configurations

Protect the binaries, systems and settings at the core of your IT.

Compliance (PCI DSS)

Provide the integrity-check evidence your audits expect.

Real-time alerting

Notify your teams immediately when a suspicious change occurs.

SIEM integration

Forward integrity events to the SIEM for correlation.

In the console

Every change opens a detail compared to the baseline — before/after fingerprint, modified attribute and drift — to qualify the deviation fast.
