File Integrity Monitoring

File Integrity Monitoring (FIM) with Atomic OSSEC

Leverage real-time FIM and intrusion detection to thwart attacks, address PCI DSS and NIST compliance

Don’t let subtle malicious changes in your IT environment go undetected. Employ the power of file integrity monitoring (FIM) to address a wide range of security and privacy compliance requirements, and mitigate organizational risk. 

File integrity monitoring (FIM) for intrusion detection and compliance

File integrity monitoring is an internal control process that checks text files and strings for anomalies, dangerous payload, configuration errors, and connective system hygiene compared against an established baseline, without having to examine the entire file. It is among the most important security capabilities needed toward avoiding infection and ransomware, and also tackling compliance requirements such as NIST, JSIG, and PCI DSS 11.5. 

  • Visibility and compliance. Discover what changed at the file, system and behavioral level, triggering active response and addressing compliance controls such as FIM and audit and accountability (AU) for data transparency. 
  • Real-time intrusion detection. Scan to detect in-progress malicious events. Real-time FIM alerts you to vanishing traces of malware execution and intruder activities that timer-based scans can miss. 
  • Response and recovery. Our FIM integrates with AV, antimalware, and automated response rules, and backs up data and logs so even if prevention efforts aren’t enough, you still have your data, your source code, your future. 
  • A nice price. Don’t pay a premium for FIM when Atomic OSSEC has you covered with pricing starting as low as $55 per server per year.

Real-Time FIM

Cyberattacks can be sneaky fast, executing their programs, altering your files and source code, and deleting traces of the activity. Many file integrity monitoring (FIM) programs run on a timer based model, only assessing a system daily, or even weekly, and don’t always catch these malicious changes. 

Need an affordable file integrity monitoring (FIM) solution for compliance and discovering and responding rapidly to malicious changes to your environment? Atomic OSSEC provides a modern, comprehensive file integrity monitoring solution at a fraction of the cost of traditional FIM solutions.  Schedule a demo today.
