n8n Security Architecture Review Workflow (GPT-4.1 Risk Scoring)

Catch security architecture risks early—automatically score and escalate with an n8n + GPT-4.1 review workflow

This n8n Security Architecture Review Workflow (GPT-4.1 Risk Scoring) consolidates your architecture inputs and runs a structured security architecture review with OpenAI GPT-4.1. It outputs an overall risk score and categorized findings, then routes the report to a standard or critical escalation path based on severity and a configurable threshold.

What this workflow does

• Runs weekly every Monday at 07:00 or can be started manually to begin a security architecture review.
• Sets review parameters, including the security frameworks to assess against, critical categories to focus on, and the critical risk-score threshold.
• Builds a single architecture context by combining your diagram description, documentation text, and infrastructure configuration.
• Extracts preliminary security signals from the provided inputs (for example, open CIDRs, missing HTTPS, or hardcoded secret patterns).
• Calls an OpenAI GPT-4.1-powered agent to generate a JSON security review containing an executive summary, overall risk score, and categorized findings.
• Parses JSON output, computes the highest finding severity, and stops early when no findings are returned.
• Creates a markdown security review summary and routes it to the standard distribution path or triggers a critical escalation when severity is Critical or the risk score exceeds the threshold.

Use cases

• SaaS operators needing a weekly security architecture check to catch drift in network exposure and transport security.
• Automation engineers reviewing new architectures by feeding diagram descriptions and configuration into a repeatable n8n workflow.
• Teams performing risk-scored security reviews that escalate only when findings cross defined critical thresholds.

Technical details

• Trigger/Orchestration: Manual Trigger; scheduled run (Mondays 07:00)
• Core logic nodes: if, set, code, wait, sticky note
• AI engine: OpenAI chat model (default gpt-4.1) using an agent to return JSON

Set up an OpenAI credential, provide the required architecture inputs, and let this n8n automation produce consistent, risk-scored security architecture reviews with actionable escalation.
