CVE Alerts to Slack and Webhooks: Setup Guide

What the team gets

• Auto-detection of CVEs from your version inventory
• Alerts to Slack or webhooks with severity filtering
• Focus on High/Critical without noise

Setup in minutes

1. Create a rule with trigger CVE Detected
2. Choose threshold (High/Critical) and channel (Slack/Webhook)
3. Save and test

For security processes

• Separate channels by environment (prod/stage)
• Keep alerts for audits (SOC2/ISO)
• Start with High+Critical, expand if needed

Response playbook (example)

• Critical: respond <24h, assign owner, track remediation
• High: <7 days, schedule patch window, verify post-patch
• Medium/Low: bundle into maintenance windows

Keep audits happy

• Store alert history (Slack archive/webhook logs)
• Note remediation dates per CVE for SOC2/ISO evidence
• Re-test after updates to close the loop
