If your product touches DoD contracts, federal agencies, or any classified or CUI environment, you already know the rule: data stays inside the boundary.
Routing ITAR-controlled data, CMMC evidence, or SIEM alerts through Zapier or Make is not a gray area — it's an immediate compliance finding that can cost you your ATO, your prime contractor relationship, or your export license.
Self-hosted n8n solves this at the infrastructure level. Your workflows run inside your GovCloud VPC, your on-prem environment, or your air-gapped network. Zapier never sees a byte.
Here are 5 complete n8n workflows built specifically for DefTech SaaS vendors and GovSec platform teams.
Workflow 1: CMMC Level 2/3 Evidence Collection Automation
The problem: CMMC Level 2 requires 110 practices. Level 3 adds 24 more. Gathering evidence from 12 different systems before every assessment is manual, error-prone, and eats weeks of your compliance team's time.
The solution: Daily automated sweep across all your evidence sources — screenshots, policy docs, log exports — with escalating alerts for overdue items.
{
"name": "CMMC Evidence Collection Automation",
"nodes": [
{"type": "n8n-nodes-base.scheduleTrigger", "name": "Daily 06:00 AM", "parameters": {"rule": {"interval": [{"field": "hours", "hoursInterval": 24}]}}},
{"type": "n8n-nodes-base.googleSheets", "name": "CMMC Evidence Checklist", "parameters": {"operation": "getAll", "sheetId": "YOUR_SHEET_ID", "range": "Evidence!A:H"}},

'OVERDUE' : daysLeft <= 7 ? 'CRITICAL' : daysLeft <= 14 ? 'URGENT' : daysLeft <= 30 ? 'WARNING' : null; return status ? {...i.json, daysLeft, status} : null; }).filter(Boolean).map(json => ({json}));"}},
{"type": "n8n-nodes-base.if", "name": "Any Overdue?", "parameters": {"conditions": {"number": [{"value1": "={{$json.length}}", "operation": "larger", "value2": 0}]}}},
{"type": "n8n-nodes-base.slack", "name": "Alert #cmmc-audit", "parameters": {"channel": "#cmmc-audit", "text": "CMMC Evidence Gap: {{$json.count}} items need attention — OVERDUE: {{$json.overdue}}, CRITICAL: {{$json.critical}}"}},
{"type": "n8n-nodes-base.gmail", "name": "Email Compliance Officer", "parameters": {"to": "compliance@yourcompany.com", "subject": "CMMC Evidence Action Required — {{$json.overdue}} Overdue Items", "message": "Daily CMMC evidence sweep complete. {{$json.count}} items require action before next assessment."}}
]
}
Key CMMC practices covered: AC.1.001, AC.2.005, AU.2.041, AU.2.042, CM.2.061, IA.1.076, IA.1.077, SC.1.175, SI.1.210
Workflow 2: FedRAMP Continuous Monitoring & ATO Renewal Tracker
The problem: FedRAMP Authorization to Operate has an expiration. Annual reviews, Plan of Action & Milestones (POA&M) updates, and ConMon deliverables all have hard deadlines. Miss one and your ATO lapses — your federal customers can't use your product.
{
"name": "FedRAMP ConMon & ATO Tracker",
"nodes": [
{"type": "n8n-nodes-base.scheduleTrigger", "name": "Daily 08:00 AM", "parameters": {"rule": {"interval": [{"field": "hours", "hoursInterval": 24}]}}},
{"type": "n8n-nodes-base.googleSheets", "name": "FedRAMP Milestone Tracker", "parameters": {"operation": "getAll", "sheetId": "YOUR_SHEET_ID", "range": "Milestones!A:I"}},
{"type": "n8n-nodes-base.code", "name": "Calculate Urgency", "parameters": {"jsCode": "const today = new Date(); return items.map(i => { const daysLeft = Math.ceil((new Date(i.json.deadline) - today) / 86400000); if (daysLeft > 60) return null; const tier = daysLeft < 0 ? 'ATO_LAPSE_RISK' : daysLeft <= 7 ? 'CRITICAL' : daysLeft <= 14 ? 'URGENT' : daysLeft <= 30 ? 'WARNING' : 'NOTICE'; return {...i.json, daysLeft, tier, json: i.json}; }).filter(Boolean).map(d => ({json: d}));"}},
{"type": "n8n-nodes-base.slack", "name": "Alert #fedramp-team", "parameters": {"channel": "#fedramp-team", "text": "FedRAMP ConMon Alert — {{$json.count}} milestones within 60 days. ATO_LAPSE_RISK items: {{$json.critical_count}}"}},
{"type": "n8n-nodes-base.gmail", "name": "Email ISSO", "parameters": {"to": "isso@yourcompany.com", "subject": "FedRAMP Action Required: {{$json.milestone_name}} Due in {{$json.daysLeft}} Days", "message": "FedRAMP milestone approaching: {{$json.milestone_name}} ({{$json.deliverable_type}}). Due: {{$json.deadline}}. Status: {{$json.status}}."}}
]
}
Milestones tracked: POA&M monthly updates, ConMon deliverables, ATO expiration, penetration test due dates, supply chain risk assessments.
Workflow 3: SIEM Alert-to-SOC Escalation Pipeline
The problem: Your SIEM fires thousands of alerts per day. L1 analysts are drowning. Critical alerts get buried. Mean time to respond (MTTR) is measured in hours, not minutes.
The solution: n8n triage layer between SIEM and your SOC — auto-classify by NIST 800-53 control, route to the right team channel, auto-escalate unacknowledged criticals.
{
"name": "SIEM-to-SOC Escalation Pipeline",
"nodes": [
{"type": "n8n-nodes-base.webhook", "name": "SIEM Alert Webhook", "parameters": {"path": "siem-alert", "httpMethod": "POST"}},
{"type": "n8n-nodes-base.code", "name": "Parse & Classify Alert", "parameters": {"jsCode": "const alert = $input.first().json; const severity = alert.severity?.toLowerCase(); const nistMapping = { 'authentication_failure': 'IA-3 / AC-17', 'data_exfiltration': 'SC-8 / SC-28 / AU-9', 'malware_detection': 'SI-3 / SI-7', 'privilege_escalation': 'AC-6 / CM-6', 'lateral_movement': 'SI-4 / SC-7', 'brute_force': 'IA-5 / AC-7' }; const alertType = alert.event_type?.toLowerCase().replace(/ /g,'_'); return [{ json: { ...alert, nist_control: nistMapping[alertType] || 'SI-4 Monitoring', escalate_immediately: severity === 'critical' || severity === 'high', soc_channel: severity === 'critical' ? '#soc-p1-critical' : severity === 'high' ? '#soc-p2-high' : '#soc-p3-medium' } }];"}},
{"type": "n8n-nodes-base.slack", "name": "Route to SOC Channel", "parameters": {"channel": "={{$json.soc_channel}}", "text": "[{{$json.severity.toUpperCase()}}] {{$json.alert_name}} — Host: {{$json.affected_host}} — NIST: {{$json.nist_control}} — Ticket: {{$json.ticket_id}}"}},
{"type": "n8n-nodes-base.if", "name": "Critical/High?", "parameters": {"conditions": {"boolean": [{"value1": "={{$json.escalate_immediately}}", "value2": true}]}}},
{"type": "n8n-nodes-base.wait", "name": "Wait 15min", "parameters": {"amount": 15, "unit": "minutes"}},
{"type": "n8n-nodes-base.httpRequest", "name": "Check Ticket Acknowledged", "parameters": {"url": "https://your-ticketing-system/api/tickets/{{$json.ticket_id}}"}},
{"type": "n8n-nodes-base.if", "name": "Unacknowledged?", "parameters": {"conditions": {"string": [{"value1": "={{$json.status}}", "value2": "open"}]}}},
{"type": "n8n-nodes-base.slack", "name": "Escalate to #soc-leadership", "parameters": {"channel": "#soc-leadership", "text": "UNACKNOWLEDGED {{$json.severity.toUpperCase()}} alert after 15 minutes: {{$json.alert_name}} on {{$json.affected_host}}. Ticket {{$json.ticket_id}} still open."}},
{"type": "n8n-nodes-base.googleSheets", "name": "Log to Incident Register", "parameters": {"operation": "append", "sheetId": "YOUR_SHEET_ID", "range": "Incidents!A:K"}}
]
}
Why self-hosted matters here: SIEM alert data contains network topology, affected host names, CVE details, and potentially CUI indicators. Routing this through a third-party SaaS is a CMMC AC.1.002 violation.
Workflow 4: ITAR/EAR Export Control Compliance Screener
The problem: Every new customer, partner, or employee onboarding must be screened against the ITAR Part 120 and EAR Entity List. Manual screening takes 20-40 minutes per record. One missed restricted-party hit = criminal liability.
{
"name": "ITAR/EAR Export Control Screener",
"nodes": [
{"type": "n8n-nodes-base.webhook", "name": "New Customer/Employee Webhook", "parameters": {"path": "export-control-screen", "httpMethod": "POST"}},
{"type": "n8n-nodes-base.code", "name": "Parse Entity & Flag Risk", "parameters": {"jsCode": "const entity = $input.first().json; const restrictedCountries = ['CN','RU','IR','KP','SY','CU','VE','BY']; const entityCountryCode = entity.country_code?.toUpperCase(); const isRestrictedCountry = restrictedCountries.includes(entityCountryCode); return [{ json: { ...entity, restricted_country_flag: isRestrictedCountry, requires_manual_review: isRestrictedCountry || entity.entity_type === 'foreign_national', review_priority: isRestrictedCountry ? 'IMMEDIATE' : 'STANDARD', ecn_required: entity.technology_category?.includes('EAR_CONTROLLED') } }];"}},
{"type": "n8n-nodes-base.if", "name": "Restricted Country?", "parameters": {"conditions": {"boolean": [{"value1": "={{$json.restricted_country_flag}}", "value2": true}]}}},
{"type": "n8n-nodes-base.slack", "name": "Alert #export-control-urgent", "parameters": {"channel": "#export-control-urgent", "text": "IMMEDIATE REVIEW REQUIRED: {{$json.entity_name}} ({{$json.country_code}}) — Restricted country flag. Do NOT provision access until export control clears."}},
{"type": "n8n-nodes-base.gmail", "name": "Email Export Control Officer", "parameters": {"to": "exportcontrol@yourcompany.com", "subject": "[ITAR/EAR] Restricted Party Screen Required: {{$json.entity_name}}", "message": "New entity requires export control screening prior to access provisioning.\n\nEntity: {{$json.entity_name}}\nCountry: {{$json.country_code}}\nType: {{$json.entity_type}}\nPriority: {{$json.review_priority}}\n\nAccess provisioning is BLOCKED pending your review."}},
{"type": "n8n-nodes-base.googleSheets", "name": "Log to EAR Compliance Register", "parameters": {"operation": "append", "sheetId": "YOUR_SHEET_ID", "range": "ExportControl!A:J"}}
]
}
Regulations covered: ITAR Part 120-130, EAR Part 744 (Entity List), OFAC SDN screening trigger, DDTC registration workflows.
Workflow 5: Weekly DefTech SaaS KPI & Security Posture Dashboard
The problem: Your CISO needs a weekly briefing that shows both business metrics (ARR, contract pipeline, renewal risk) and security posture (open POA&M items, CMMC gap count, incident MTTR). Building it manually takes 3 hours every Monday.
{
"name": "Weekly DefTech KPI & Security Posture Dashboard",
"nodes": [
{"type": "n8n-nodes-base.scheduleTrigger", "name": "Monday 07:00 AM", "parameters": {"rule": {"interval": [{"field": "cronExpression", "expression": "0 7 * * 1"}]}}},
{"type": "n8n-nodes-base.googleSheets", "name": "Pull KPI Data", "parameters": {"operation": "getAll", "sheetId": "YOUR_SHEET_ID", "range": "KPIs!A:Z"}},
{"type": "n8n-nodes-base.code", "name": "Build KPI Summary", "parameters": {"jsCode": "const rows = items.map(i => i.json); const kpis = rows[0] || {}; const html = '<h2>DefTech Weekly Dashboard</h2><table border=1 cellpadding=8><tr><th>Metric</th><th>This Week</th><th>WoW</th></tr>' + Object.entries(kpis).filter(([k]) => k !== 'week_of').map(([k,v]) => `<tr><td>${k.replace(/_/g,' ')}</td><td>${v}</td><td>${kpis[k+'_wow'] || '-'}</td></tr>`).join('') + '</table>'; return [{ json: { html_report: html, week_of: kpis.week_of, open_poam_items: kpis.open_poam_items, cmmc_gap_count: kpis.cmmc_gap_count, ato_days_remaining: kpis.ato_days_remaining } }];"}},
{"type": "n8n-nodes-base.gmail", "name": "Email CISO & Program Manager", "parameters": {"to": "ciso@yourcompany.com", "subject": "DefTech Weekly Dashboard — Week of {{$json.week_of}} | ATO: {{$json.ato_days_remaining}} days | Open POA&M: {{$json.open_poam_items}}", "message": "={{$json.html_report}}"}},
{"type": "n8n-nodes-base.slack", "name": "Post to #leadership", "parameters": {"channel": "#leadership", "text": "Weekly DefTech KPI digest posted. ATO days remaining: {{$json.ato_days_remaining}} | Open POA&M: {{$json.open_poam_items}} | CMMC gaps: {{$json.cmmc_gap_count}}"}}
]
}
Why Self-Hosted n8n Is Non-Negotiable for DefTech
| Requirement | Zapier/Make | Self-Hosted n8n |
|---|---|---|
| CUI stays in boundary | No — cloud routes data | Yes — runs in your VPC |
| ITAR compliance | No — foreign servers | Yes — you control deployment |
| FedRAMP High eligibility | No | Yes (on IL4/IL5 infra) |
| CMMC ConMon evidence | No — third-party cloud = finding | Yes — git-JSON = audit trail |
| Air-gapped deployment | No | Yes — on-prem possible |
| Per-execution cost at scale | $$/month | $0 — self-hosted is unlimited |
For DoD contractors and GovSec SaaS vendors, n8n's self-hosted model isn't just a cost advantage — it's the only architecture that doesn't create a compliance violation.
