Weekly n8n Security Audit Workflow: Supabase + Gmail Alerts

Weekly n8n Security Audit Workflow that alerts you in Gmail

This Weekly n8n Security Audit Workflow automatically runs a security check on a scheduled basis and uses Supabase data to drive results, then sends timely Gmail alerts—so you can stay ahead of potential issues without manually monitoring your automations.

What this workflow does

• Runs on a weekly cadence: the workflow is designed to perform recurring security auditing at a consistent interval.
• Uses Supabase as the source of security audit data: it leverages Supabase to store and retrieve information involved in the audit process.
• Sends alerts via Gmail: when the workflow detects relevant conditions, it delivers notifications to the right recipients using an n8n Gmail sending step.
• Includes error handling: an Error Trigger is included to catch failures and react quickly, rather than silently missing an audit run.

Use cases

• SaaS operators: ensure weekly security hygiene for internal tooling and immediately notify your team when something needs attention.
• Automation engineers: verify that security-related data and checks remain healthy over time, with Gmail notifications for visibility.
• Security-conscious n8n teams: maintain a lightweight audit routine backed by Supabase, with alerting that fits everyday operational workflows.

Technical details

• Supabase integration (data-driven audit workflow logic)
• n8n-nodes-resendresend node (used as part of the workflow’s notification sending capability)
• Gmail alert delivery as the notification channel
• Error Trigger for robust failure handling and quicker awareness
• Sticky note elements to improve readability and maintainability

If you’re looking for an n8n automation workflow that performs a weekly security audit with actionable Gmail alerts and Supabase-backed logic, this workflow is built for practical, ongoing operations.
