Venafi Slack CertBot Automated Certificate Issuance and Security Risk Assessment Workflow

Workflow Name

Venafi Slack CertBot Automated Certificate Issuance and Security Risk Assessment Workflow

Key Features and Highlights

This workflow, built on the n8n platform, enables certificate issuance requests to be initiated directly via Slack. It integrates VirusTotal’s domain security scanning and OpenAI’s intelligent risk analysis to facilitate an automated or manual approval TLS certificate application process. The user interface leverages Slack’s interactive Modals for convenient and responsive operations, significantly enhancing the efficiency and accuracy of security operations.

Core Problems Addressed

• Simplifies and automates the certificate issuance process, eliminating the complexity and error-prone nature of traditional manual applications.
• Provides real-time domain security risk detection combined with AI-driven analysis to support decision-making and strengthen certificate issuance security.
• Centralizes certificate request management with support for both automated and manual approval workflows, ensuring security compliance.
• Optimizes the security operations interaction experience within Slack, reducing operational response times.

Use Cases

• Enterprise security operations teams quickly initiating certificate issuance requests via Slack.
• Organizations requiring automatic security scanning and risk assessment of domains involved in certificate applications.
• Scenarios that combine automated and manual approval processes to ensure secure and compliant certificate management.
• Using Slack as a security operations hub integrating multiple security tools and approval workflows.

Main Workflow Steps

1. Listen to Slack Events (Webhook): Capture user interactions and form submissions within Slack.
2. Parse Slack Message Content: Extract user inputs such as domain name, validity period, and remarks.
3. Display Interactive Modal Window: Collect detailed certificate request information through Slack Modals.
4. Invoke VirusTotal API: Perform security scans on the requested domain, retrieving indicators such as malicious or suspicious statuses.
5. Invoke OpenAI Model: Intelligently analyze VirusTotal scan results to generate a risk rating (Low, Medium, High).
6. Risk-Based Routing:
   • Low Risk: Automatically call Venafi TLS Protect Cloud to generate and issue the certificate.
   • Medium/High Risk: Generate a detailed risk report and send it to a designated Slack channel for manual security team approval.
7. Retrieve Slack User and Team Information: Use a sub-workflow to convert Slack user IDs to email addresses and team IDs to team names and avatars for message enrichment and contextualization.
8. Venafi Certificate Issuance: Based on approval results, automatically or manually invoke Venafi API to generate the CSR (Certificate Signing Request) and issue the certificate.
9. Slack Notifications: Automatically send formatted messages to relevant team channels indicating certificate issuance success or pending approval status, including certificate details and action buttons.
