Do You Need a 24/7 SOC for CMMC Level 2 Compliance?
For most aerospace and DoD supply chain manufacturers, a 24/7 Security Operations Center (SOC) is not explicitly named as a requirement in CMMC Level 2, but in practice, it is essential to meet multiple NIST 800-171 controls, especially around continuous monitoring, incident response, and audit logging. For organizations with 25 to 250 users, SOC capabilities are typically included within the $125 to $225 per user per month managed IT range and play a critical role in achieving and maintaining compliance.
What CMMC Level 2 Actually Requires (Behind the Scenes)
CMMC Level 2 is based on 110 NIST 800-171 controls, many of which require:
- Continuous monitoring of systems
- Detection of unauthorized activity
- Logging and audit trail retention
- Incident response capabilities
While "SOC" isn't named directly, these requirements effectively demand SOC-level capabilities.
What a 24/7 SOC Actually Does
1. Continuous Monitoring
Tracks system activity 24/7 and identifies suspicious behavior in real time.
2. Threat Detection and Response
Uses SIEM and MDR tools to detect anomalies and potential breaches, and initiates response actions immediately.
3. Log Collection and Analysis
Aggregates logs across all systems, maintains required audit trails, and supports compliance reporting.
4. Incident Response Support
Investigates alerts, contains threats, and documents incidents for compliance.
Why Most Manufacturers Fail Without a SOC
Without SOC capabilities, companies typically:
- Miss critical security events
- Lack proper logging for audits
- Cannot respond to incidents in time
- Fail to meet multiple NIST control requirements
This is one of the most common reasons for failed CMMC readiness assessments.
SOC vs. Basic IT Monitoring: The Critical Difference
| Basic IT Monitoring | 24/7 SOC |
|---|---|
| Alerts only during business hours | Continuous 24/7 monitoring |
| Limited visibility | Full system-wide visibility |
| No threat hunting | Active threat detection |
| Reactive support | Proactive security |
Illustrative Scenario. Consider a 90-employee manufacturer handling CUI for DoD contracts, using a traditional MSP with basic business-hours monitoring only. A gap assessment identified no centralized log collection, no 24/7 monitoring, no formal incident response capability, and limited audit trail visibility. Within 60 to 90 days of deploying SIEM and MDR, establishing 24/7 SOC monitoring, centralizing logging, and implementing incident response workflows, the organization met key NIST 800-171 monitoring and logging requirements and was positioned for CMMC Level 2 audit readiness within 6 to 9 months. This is a representative example, not a specific client engagement.
How SOC Impacts Your CMMC Cost
SOC capabilities typically represent $50 to $150 per user per month within your total managed IT spend, a significant portion of your overall compliance investment. However, without it:
- Audit failure risk increases
- Remediation costs go up
- Timeline extends significantly
How to Evaluate a SOC for CMMC Compliance
Use this framework:
- Is monitoring truly 24/7?
- Does it include SIEM and MDR?
- Are logs retained and accessible for audits?
- Is incident response documented and tested?
Trust Signals
Look for providers that:
- Have experience with CMMC environments
- Offer integrated SIEM and MDR solutions
- Support audit preparation and documentation
- Work with aerospace and DoD manufacturers
Bottom Line
While a 24/7 SOC is not explicitly labeled as a requirement in CMMC Level 2, it is functionally required to meet the core security and monitoring controls. Manufacturers that implement SOC capabilities achieve compliance faster, reduce audit risk, and maintain ongoing security posture.
Not sure if your current provider includes true 24/7 SOC capabilities? Start with a gap assessment to identify your monitoring and compliance gaps.

Frequently Asked Questions
Does CMMC Level 2 explicitly require a 24/7 SOC?
No, CMMC Level 2 does not name a SOC by title. But the continuous monitoring, audit logging, and incident response requirements across the 110 NIST 800-171 controls functionally require SOC-level capabilities to satisfy them.
How much does 24/7 SOC coverage cost?
SOC capabilities typically run $50 to $150 per user per month, included within a broader managed IT package priced at $125 to $225 per user per month for most CMMC-aligned manufacturers.
Can I pass a CMMC Level 2 assessment without a SOC?
It's unlikely. Without continuous monitoring and centralized logging, organizations typically fail assessment objectives tied to audit trail retention, incident detection, and response time, which are core requirements across multiple control families.
What's the difference between basic IT monitoring and a real SOC?
Basic monitoring typically alerts only during business hours with limited visibility and no active threat hunting. A true SOC provides continuous 24/7 monitoring, full system-wide visibility, active threat detection, and proactive rather than reactive response.
