Meeting CMMC 2.0 incident reporting requirements isn’t optional if you handle Controlled Unclassified Information (CUI) in the Defense Industrial Base. You need to detect, contain, and report an incident to the DoD within 72 hours — and document every step for a potential Level 2 or Level 3 certification audit. CyberSilo’s ThreatHawk MSSP SIEM gives you a managed detection and response (MDR) capability purpose-built for these reporting mandates, with typical alert triage times under eight minutes and audit-ready evidence packages generated in hours — not weeks.
For CISOs and security architects at US-based contractors, the challenge is clear: CMMC incident reporting demands more than just a SIEM tool. You need a 24/7 SOC that can validate alerts, scope incidents, and produce the forensic record required for a CMMC Assessment Scope review. CyberSilo’s MDR service maps directly to CMMC’s three key reporting processes — detect, contain, and document — and does it across the 110 NIST SP 800-171 controls that underlie CMMC Level 2. The result is compliance-driven threat management that keeps your DFARS clause flow-down obligations met without straining your internal team.
Why CMMC Incident Reporting Requires an MDR Service
CMMC 2.0, managed by the Cybersecurity Maturity Model Certification Accreditation Body (CMMC-AB) and enforced by the DoD, requires Level 2 contractors to report all qualifying cyber incidents to the DoD within 72 hours of discovery. That window starts the moment you have reasonable basis to believe an incident occurred — not when you have confirmed it. For a typical mid-market contractor running a legacy SIEM with one or two analysts, that clock starts ticking long before the incident is even identified.
The core problem is that CMMC incident reporting isn’t just an operational workflow; it’s a compliance artifact that will be examined during your Level 2 certification assessment. The CMMC Assessment Process requires evidence of three specific capabilities:
- IR.2.094: Detect and report events in a timely manner to authorized personnel and the DoD.
- IR.2.095: Analyze and triage events to determine if they are reportable incidents.
- IR.2.096: Contain and eradicate incidents, then produce documentation for follow-on reporting.
Without a managed MDR service, your team must handle detection, triage, containment, and documentation — all while the compliance clock is running. A typical in-house SOC spends 40-60% of its time on false positives, delaying the critical 72-hour window. CyberSilo’s MDR eliminates that delay by filtering noise before it reaches your analysts and escalating verified incidents within minutes.
Key CMMC reality: The 72-hour reporting clock under DFARS 252.204-7012 starts at the point of discovery, defined as when you have a reasonable basis to believe a cyber incident has occurred. If your detection tooling takes 24 hours to surface an alert and another 12 hours to triage it, you’ve already burned half your reporting window. CyberSilo’s average detection-to-escalation time is under 30 minutes — giving you the full 72 hours for proper documentation and submission.
How ThreatHawk MSSP SIEM Meets CMMC Reporting Processes
CyberSilo’s ThreatHawk MSSP SIEM is a fully managed MDR service that combines SIEM ingestion, SOAR automation, and 24/7 SOC analyst coverage. It’s designed to satisfy CMMC incident reporting requirements as an integrated capability — not as a suite of tools you must stitch together. Here’s how it maps to each CMMC reporting stage.
Detection and Event Correlation
ThreatHawk ingests logs from all NIST 800-171 control families — access control (AC), audit and accountability (AU), configuration management (CM), identification and authentication (IA), incident response (IR), maintenance (MA), media protection (MP), physical protection (PE), system and communications protection (SC), and system and information integrity (SI). The SIEM correlates these logs against 1,200+ threat intelligence feeds and maps every alert to the relevant CMMC control. The result: when an incident occurs, your compliance evidence is tied directly to the assessment objective, not buried in raw logs.
Triage and Validated Incident Scoping
CMMC requires you to not just detect an event but to scope it — determine what systems, data types, and CUI categories were affected. ThreatHawk’s SOAR engine automatically enriches each alert with asset context, data classification tags, and user behavior analytics. A typical incident scope report is generated in under 10 minutes, including the systems, affected CUI, and initial impact assessment. This scoped package then feeds directly into your DFARS 252.204-7012 damage assessment report.
Containment and Forensic Evidence
CMMC Level 2 requires evidence that containment actions were taken within a defined SLAs — and that those actions preserved forensic integrity for potential DoD investigation. ThreatHawk’s automated playbooks handle network segmentation, endpoint isolation, and credential revocation within seconds, while simultaneously creating a chain-of-custody forensic artifact. Every containment action is timestamped, user-attributed (via the SOC analyst), and logged with the specific CMMC control it supports.
CMMC 72-Hour Reporting Workflow with CyberSilo
Alert Triggered & Verified by SOC
An anomaly is detected across your network, endpoint, or cloud environment. ThreatHawk’s correlation engine routes it to a live CyberSilo SOC analyst within 90 seconds. The analyst triages the alert against known threat patterns and CMMC-sensitive data types. Typical verification time: under 8 minutes.
Incident Scoped & Classified
If verified as a reportable incident (e.g., CUI accessed by an unauthorized entity), the SOAR engine scopes the incident. The system identifies affected systems, affected CUI categories, and potential CMMC Assessment Objectives impacted. The scope report is automatically created in the format required for DoD submission.
Containment Executed with Forensic Hold
Automated playbooks isolate affected endpoints, block malicious IPs, and revoke compromised credentials. A forensic snapshot is captured before any remediation actions are taken, preserving the evidence chain for the CMMC assessor or DoD investigation.
DoD Report Generated & Submitted
ThreatHawk generates the complete DFARS 252.204-7012 damage assessment report, including incident description, affected CUI, systems impacted, containment actions taken, and forensic artifact IDs. The report is formatted for submission to the DoD via the required channels. Average time from alert to submission-ready report: under 90 minutes.

Control Mapping: ThreatHawk to CMMC Incident Response Requirements
For CISOs and assessors preparing for a CMMC Level 2 certification, the critical question is how each MDR capability maps to a specific CMMC practice and process. The table below shows the direct mapping between CyberSilo’s MDR capabilities and the CMMC Level 2 incident response (IR) and related controls.
How CyberSilo Compares to In-House MDR for CMMC Compliance
Running an in-house MDR capability for CMMC compliance requires maintaining 24/7 SOC coverage, integrating SIEM tools, building and testing SOAR playbooks, and continuously mapping logs to NIST 800-171 controls — a significant operational and cost burden for most mid-market defense contractors. The following comparison shows where CyberSilo’s managed MDR service delivers clear advantages for CMMC-bound organizations.
Implementation Workflow for Defense Contractors
Deploying CyberSilo’s MDR for CMMC incident reporting follows a structured integration path designed to minimize disruption to your existing security tooling while ensuring complete NIST 800-171 log coverage.
Assess Current Log Sources & CUI Environments
CyberSilo’s integration team audits your existing infrastructure — network devices, endpoints, cloud workloads, and on-premise systems — to identify all log sources required for CMMC audit and accountability (AU) control coverage. We identify any gaps in coverage for NIST 800-171 access control (AC) and system and communications protection (SC) logs.
ThreatHawk SIEM Configuration & Control Mapping
Your log sources are configured to feed into the ThreatHawk MSSP SIEM. Each log type is mapped to the corresponding CMMC practice and process. The SIEM’s correlation rules are adjusted to match your specific CUI environments and your 72-hour reporting threshold.
SOC Handoff & Playbook Customization
The CyberSilo SOC team receives your environment details, escalation contacts, and containment preferences. SOAR playbooks are customized to align with your internal response procedures while preserving the evidence chain for CMMC assessors. The system is then activated for 24/7 monitoring.
First 90-Day Compliance Validation
During the first quarter, CyberSilo runs a compliance validation review that cross-checks all incident alerts against your CMMC control coverage. The output is a gap analysis report showing any areas where additional log sources or detection rules are needed for full Level 2 or Level 3 readiness.

When to Prioritize CyberSilo Over Building an In-House MDR
Not every defense contractor needs the same approach. CyberSilo’s managed MDR service is typically the best fit when you face one or more of the following conditions:
- You have under 10 analysts in your SOC: Small teams simply cannot maintain 24/7 coverage for CMMC detection and triage without burnout or gaps. CyberSilo’s SOC acts as an extension of your team, not a replacement.
- Your CMMC certification assessment is within 12 months: Building a mature MDR capability in-house within that timeframe is extremely difficult. CyberSilo’s deployment timeline of 3-5 days gives you an operational MDR capability before your assessment window closes.
- You need to demonstrate DFARS §252.204-7012 compliance to a prime contractor: Many prime contractors now require subcontractors to show evidence of an active MDR or SOC capability. CyberSilo’s service documentation serves as that evidence for flow-down compliance.
- Your CUI environment spans multiple enclaves or cloud providers: ThreatHawk’s multi-tenant architecture ingests logs from AWS, Azure, on-premise, and industrial control systems (ICS) — reflecting the diverse environments common among defense contractors.
