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.
