Does CMMC Require a SIEM?
Short answer: no, CMMC does not require the purchase of a specific class of product called "SIEM." But centralized logging, monitoring, retention and investigation are commonly part of how organizations satisfy the underlying security requirements.
What CMMC actually requires, in plain terms
CMMC Level 2 is built on NIST SP 800-171, which includes requirement families covering audit logging, log review, incident response, and monitoring for unauthorized access.
Audit logging
Generating and retaining logs of security-relevant events across systems handling covered information.
Log review
Reviewing logs for indicators of unauthorized activity, not just collecting them.
Incident response
Having a documented process to detect, investigate, and respond to security incidents.
Monitoring
Ongoing monitoring for unauthorized access attempts and anomalous activity.
How Ironclad supports these outcomes
Ironclad is a tool your organization can use as part of meeting these requirements — not a compliance certification.
Centralized logging
Endpoints, identity systems, Microsoft 365 and network sources feed into one place instead of living in disconnected tools.
Retention
30 days of hot (searchable) retention plus 365 days of cold retention, included on every license.
Detection & investigation
Correlated events and a case-management workflow your team can use to review and act on suspicious activity.
Reporting
Automated reports you can use as supporting evidence of your ongoing monitoring practices.
