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 required by name 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 25–250 users, implementing SOC capabilities typically accounts for $50–$150 per user/month and plays 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
A properly implemented SOC provides:
1. Continuous Monitoring
- Tracks system activity 24/7
- Identifies suspicious behavior in real time
2. Threat Detection & Response
- Uses SIEM + MDR tools
- Detects anomalies and potential breaches
- Initiates response actions immediately
3. Log Collection & Analysis
- Aggregates logs across all systems
- Maintains required audit trails
- Supports compliance reporting
4. Incident Response Support
- Investigates alerts
- Contains threats
- 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” (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 |
Example Scenario: 90-User Manufacturer Without SOC Coverage
Company Profile
- 90 employees
- Handles CUI for DoD contracts
- Using traditional MSP with basic monitoring
Initial Gaps Identified
- No centralized log collection
- No 24/7 monitoring
- No formal incident response capability
- Limited audit trail visibility
Implementation (First 60–90 Days)
- Deployed SIEM + MDR platform
- Established 24/7 SOC monitoring
- Centralized logging across all systems
- Implemented incident response workflows
Outcome
- Met key NIST 800-171 monitoring and logging requirements
- Improved threat detection and response time
- Positioned for CMMC Level 2 audit readiness within 6–9 months
How SOC Impacts Your CMMC Cost
SOC services typically represent:
- $50–$150 per user/month of your total IT cost
- A significant portion of your 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 + 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 + 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
- Maintain ongoing security posture
Next Step:
Evaluate whether your current IT provider includes true 24/7 SOC capabilities, or start with a gap assessment to identify monitoring and compliance gaps.
