Track system changes continuously, detect malware and intrusion, and meet compliance where file integrity monitoring (FIM) is required—with Atomicorp’s FIM as a Service.
Affordable File Integrity Monitoring (FIM) as a Service
Forensic file integrity monitoring (FIM) is a core cybersecurity control and a requirement under major compliance frameworks, including PCI DSS, NIST 800-53, NIST 800-171, FISMA, ISO/IEC 27001, and NERC CIP. Yet FIM is often bundled into broad, enterprise security platforms, leaving organizations that already have antivirus and incident response capabilities searching for a focused, standalone FIM solution to meet specific compliance needs.
Just need file integrity monitoring (FIM)? — Atomicorp FIM as a Service provides affordable, easy-to-use file integrity monitoring, enabling SMBs and first-time FIM adopters to detect unauthorized changes in real time and satisfy PCI DSS requirements.
Atomicorp’s new monthly FIM as a Service includes:
- Real-time detection – Know within milliseconds when files are added, modified, or deleted.
- Who and where data – Identify who made the change and where they logged in from, across most operating systems.
- Change tracking – Maintain records of file changes alongside previous versions.
- Reversion – Roll back files to prior versions when needed.
- Legacy OS-compatible / legacy-safe operation – Agentless, scheduled monitoring that won’t disrupt sensitive legacy or end-of-life IT and OT systems.
- Hash-based verification – Before-and-after hashes validate that changes actually occurred and support SIEM or SOC workflows.
- And more.
