n8n for Cybersecurity SaaS Companies: 5 Automations That Scale SecOps and Customer Ops (Free Workflow JSON)

#n8n #security #automation #programming

If you're building a cybersecurity SaaS product — an endpoint security platform, a SIEM, a vulnerability management tool, an identity security company, or an MDR service — you face a painful irony:

Your customers trust you to protect their security. But your internal ops are often full of manual work, brittle spreadsheets, and alert fatigue.

n8n fixes this. Self-hosted, open-source, and git-versionable — it's the workflow engine that fits a security-first culture without creating a new data egress risk.

(Note: This article is for cybersecurity **companies* building security software. If you're a security team using tools, check out 5 Automations for Security Teams.)*

Why Cybersecurity SaaS Companies Choose n8n

Concern	How n8n Addresses It
Data egress	Self-hosted: CVE research, customer security questionnaires, and VDP reports never touch a third-party cloud
SOC2 CC6.1 finding	Using Zapier/Make for internal security ops can appear in your own audit as a data egress finding
Git-versioned workflows	JSON workflows live in your repo — auditable, change-tracked, PR-reviewed
Cost at scale	Zero per-execution fees — runs millions of ops/month at flat infra cost
Vendor trust signal	Self-hosting your own automation stack is a credibility signal to enterprise buyers

Workflow 1: VDP / Bug Bounty Report Auto-Triage

Use case: Your vulnerability disclosure program (VDP) receives reports 24/7. Manual triage creates SLA risk and researcher frustration. This workflow auto-classifies, ACKs researchers instantly, and routes to the right team.

{
  "name": "VDP Bug Bounty Auto-Triage",
  "nodes": [
    {"name": "VDP Webhook", "type": "n8n-nodes-base.webhook",
     "parameters": {"path": "vdp-report", "responseMode": "responseNode"}},
    {"name": "Classify Severity", "type": "n8n-nodes-base.code",
     "parameters": {"jsCode": "const body = $json.body || {};\nconst title = (body.title || '').toLowerCase();\nconst desc = (body.description || '').toLowerCase();\nconst cvss = parseFloat(body.cvss_score) || 0;\n\nlet severity;\nif (cvss >= 9.0 || title.includes('rce') || title.includes('remote code') || desc.includes('privilege escalation')) {\n  severity = 'CRITICAL';\n} else if (cvss >= 7.0 || title.includes('auth bypass') || title.includes('sqli') || title.includes('injection')) {\n  severity = 'HIGH';\n} else if (cvss >= 4.0 || title.includes('xss') || title.includes('csrf') || title.includes('idor')) {\n  severity = 'MEDIUM';\n} else {\n  severity = 'LOW';\n}\n\nreturn [{ json: { ...body, severity, report_id: body.report_id || Date.now().toString(), received_at: new Date().toISOString() } }];"}},
    {"name": "Route by Severity", "type": "n8n-nodes-base.switch",
     "parameters": {"rules": [{"value1": "={{$json.severity}}", "operation": "equal", "value2": "CRITICAL"}, {"value1": "={{$json.severity}}", "operation": "equal", "value2": "HIGH"}]}},

    {"name": "ACK Email to Researcher", "type": "n8n-nodes-base.gmail",
     "parameters": {"to": "={{$json.reporter_email}}", "subject": "VDP Report Received — {{$json.report_id}}", "message": "Thank you for your submission. Your report has been received and assigned ID {{$json.report_id}}.\n\nSeverity Assessment: {{$json.severity}}\nExpected Response SLA: {{$json.severity === 'CRITICAL' ? '24 hours' : $json.severity === 'HIGH' ? '72 hours' : '7 business days'}}\n\nWe appreciate your responsible disclosure."}}
  ]
}

Workflow 2: Customer Security Questionnaire Automation

Use case: Every enterprise prospect sends a 50-100 question security questionnaire. Your security team spends days answering the same questions. This workflow auto-handles the FAQ questions and routes only truly custom ones to your team.

{
  "name": "Security Questionnaire Handler",
  "nodes": [
    {"name": "Gmail Trigger", "type": "n8n-nodes-base.gmailTrigger",
     "parameters": {"filters": {"subject": "security questionnaire", "hasAttachment": false}}},
    {"name": "Claude Classify", "type": "@n8n/n8n-nodes-langchain.openAi",
     "parameters": {"model": "claude-haiku-4-5", "prompt": "Classify this security questionnaire email as:\n- FAQ: Questions about SOC2, ISO27001, GDPR, penetration testing, data encryption, subprocessors — answerable from our trust page\n- CUSTOM: Bespoke questions about specific architectures, custom data handling, onsite audits\n\nEmail: {{$json.snippet}}\n\nRespond with JSON: {\"type\": \"FAQ\" or \"CUSTOM\", \"summary\": \"one line summary\"}"}},
    {"name": "Route Type", "type": "n8n-nodes-base.if",
     "parameters": {"conditions": {"string": [{"value1": "={{$json.type}}", "operation": "equal", "value2": "FAQ"}]}}},
    {"name": "Auto-Reply FAQ", "type": "n8n-nodes-base.gmail",
     "parameters": {"operation": "reply", "to": "={{$node['Gmail Trigger'].json.from}}", "message": "Thank you for your security questionnaire. For standard questions about our security posture, please visit our Trust Center:\n\nhttps://trust.yourcompany.com\n\nYou'll find our SOC2 Type II report, penetration test summary, data processing agreements, and subprocessor list.\n\nIf you have custom architecture or compliance questions, our security team will follow up within 2 business days."}},
    {"name": "Slack Custom to Team", "type": "n8n-nodes-base.slack",
     "parameters": {"channel": "#sec-sales-support", "text": ":lock: Custom Security Questionnaire\nFrom: {{$node['Gmail Trigger'].json.from}}\nSummary: {{$json.summary}}\nSubject: {{$node['Gmail Trigger'].json.subject}}\n@security-team — please review and respond within 48h"}},
    {"name": "Log All Requests", "type": "n8n-nodes-base.googleSheets",
     "parameters": {"operation": "append", "sheetId": "YOUR_SHEET_ID", "range": "Questionnaires!A:E"}}
  ]
}

Workflow 3: CVE Impact Assessment & Internal Advisory Pipeline

Use case: When a new critical CVE drops, you need to quickly assess if it impacts your product stack and notify the right teams — before customers ask. This workflow monitors NVD and CISA KEV daily.

{
  "name": "CVE Impact Assessment Pipeline",
  "nodes": [
    {"name": "Daily 8AM", "type": "n8n-nodes-base.scheduleTrigger",

    {"name": "Merge Feeds", "type": "n8n-nodes-base.merge",
     "parameters": {"mode": "combine"}},
    {"name": "Filter & Classify", "type": "n8n-nodes-base.code",
     "parameters": {"jsCode": "const nvdItems = $input.all()[0]?.json?.CVE_Items || [];\nconst kevItems = $input.all()[1]?.json?.vulnerabilities || [];\nconst kevCves = new Set(kevItems.map(v => v.cveID));\n\n// YOUR STACK — customize these keywords\nconst stackKeywords = ['openssl', 'nginx', 'node.js', 'react', 'postgresql', 'redis', 'docker', 'kubernetes', 'aws', 'linux kernel'];\n\nconst relevant = nvdItems\n  .filter(item => {\n    const cvss = item.impact?.baseMetricV3?.cvssV3?.baseScore || 0;\n    const desc = (item.cve?.description?.description_data?.[0]?.value || '').toLowerCase();\n    const isHighSeverity = cvss >= 7.0;\n    const isStackRelevant = stackKeywords.some(k => desc.includes(k));\n    return isHighSeverity && isStackRelevant;\n  })\n  .map(item => {\n    const cveId = item.cve?.CVE_data_meta?.ID;\n    return {\n      cve_id: cveId,\n      cvss: item.impact?.baseMetricV3?.cvssV3?.baseScore,\n      description: item.cve?.description?.description_data?.[0]?.value,\n      is_actively_exploited: kevCves.has(cveId),\n      published: item.publishedDate\n    };\n  });\n\nreturn relevant.map(r => ({ json: r }));"}},
    {"name": "Slack Product Security", "type": "n8n-nodes-base.slack",
     "parameters": {"channel": "#product-security", "text": ":shield: CVE Alert: {{$json.cve_id}} (CVSS {{$json.cvss}}){{$json.is_actively_exploited ? ' — :fire: ACTIVELY EXPLOITED (CISA KEV)' : ''}}\n{{$json.description}}\nPublished: {{$json.published}}"}},

  ]
}

Workflow 5: Weekly Security Metrics & Customer Trust Briefing

Use case: Your CISO and CEO need a weekly pulse on security posture — vulnerability backlog, mean time to detect/respond, customer security tickets, and audit readiness. This workflow auto-builds the report every Friday.

{
  "name": "Weekly Security Metrics Briefing",
  "nodes": [
    {"name": "Friday 4PM", "type": "n8n-nodes-base.scheduleTrigger",
