Preflyt - Post-Deploy Security Scan

After deploying a web app, API, or backend to a public URL, run a Preflyt scan to detect exposed secrets, misconfigurations, and unsafe defaults.

When to use this

• After deploying a web application to production or staging
• After deploying a backend API (Node, Python, Go, etc.)
• After any infrastructure change that exposes a new URL

How to run a scan

npx preflyt-check https://your-deployed-url.com

With options:

# Fail if issues found (for CI/CD)
npx preflyt-check https://your-deployed-url.com --fail

# Generate a shareable report link
npx preflyt-check https://your-deployed-url.com --share

# With Pro license for unlimited scans
npx preflyt-check https://your-deployed-url.com --key YOUR_LICENSE_KEY

Exit codes:

• 0: scan completed, no issues (or issues found without --fail)
• 1: issues found with --fail set, or scan error

What it checks

• Exposed .env and config files (database passwords, API keys)
• Exposed .git repositories (source code leakage)
• Exposed backend source code (app.py, server.js, config.php served as static files)
• Exposed database files (dynamic detection using project name - {name}.db, {name}.sqlite3)
• Open database ports (MySQL, PostgreSQL, MongoDB, Redis, Elasticsearch)
• Directory listing detection and dangerous file parsing
• Exposed admin panels and debug endpoints
• Missing security headers (HSTS, CSP, X-Frame-Options, CORS)
• Exposed backup files and source maps
• Server version leakage
• Insecure cookie flags

What it does NOT do

• Does not scan source code or local files
• Does not perform exploit attempts
• Does not test authentication logic
• Does not scan localhost or private networks
• Does not read or transmit any local environment variables, files, or code

Privacy

• Without --share: all results display in the terminal only. No data is sent to preflyt.dev beyond the initial scan request containing the target URL.
• With --share: scan results are uploaded to preflyt.dev and a public report link is generated (valid 30 days).
• The scan sends only the target URL to api.preflyt.dev. No local files, code, or environment variables are transmitted.
• The npm package is open source and zero-dependency: https://github.com/doureios39/preflyt-check

Integration examples

Deploy script

#!/bin/bash
git pull
npm run build
pm2 restart app
sleep 5
npx preflyt-check https://mysite.com --fail || echo "Security issues found"

Git hook (post-receive)

#!/bin/bash
# .git/hooks/post-receive
git pull
npm run build
pm2 restart app
sleep 5
npx preflyt-check https://mysite.com

GitHub Actions

- name: Security scan
  run: npx preflyt-check ${{ env.DEPLOY_URL }} --fail

Agent behavior

When a deployment to a public URL is detected:

1. Run npx preflyt-check <deployed-url>
2. If HIGH severity findings exist, recommend immediate fix
3. If MEDIUM or LOW findings, inform the user and suggest fixes
4. If no findings, confirm deployment appears safe
5. Never let a Preflyt error block a deployment - if the scan fails, report the error and move on

Notes

• All checks are read-only and non-intrusive
• Scans take approximately 15-30 seconds
• Free tier: 3 scans. Pro ($9.99/mo): unlimited
