Launch Ready cyber security Checklist for internal admin app: Ready for app review in marketplace products?

If your internal admin app is going into a marketplace product review, "ready" does not mean "it works on my machine." It means the app can survive a security review, an install review, and a basic abuse test without exposing customer data, breaking auth, or getting rejected for sloppy deployment hygiene.

For this product type, I would define ready as:

• No exposed secrets in the repo, build output, or client bundle.
• Auth is enforced on every admin route and API action.
• Tenant or account boundaries are tested, not assumed.
• Production uses HTTPS, correct redirects, and locked-down headers.
• Email authentication passes SPF, DKIM, and DMARC.
• Monitoring exists before launch, not after the first incident.
• The app can be reviewed without a reviewer hitting dead links, broken callbacks, or permission leaks.

If you cannot confidently say "zero critical auth bypasses, zero exposed secrets, and all production traffic forced through HTTPS," it is not ready.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | | --- | --- | --- | --- | | Auth on admin routes | Every admin page and API requires authenticated access | Prevents unauthorized access to sensitive controls | Data exposure, account takeover risk | | Role-based access control | Users only see actions allowed by their role | Reviewers will test privilege boundaries | Privilege escalation | | Secret handling | No secrets in client code or public repos | Prevents token theft and abuse | API compromise, billing abuse | | HTTPS everywhere | All traffic redirects to SSL with no mixed content | Required for trust and secure sessions | Login failure, browser warnings | | Secure headers | CSP, HSTS, X-Frame-Options or frame-ancestors set correctly | Reduces clickjacking and injection impact | Session theft, UI redress attacks | | Input validation | Server validates all admin inputs and webhooks | Stops malformed payloads and abuse | Injection bugs, broken data | | Logging hygiene | Logs exclude passwords, tokens, PII where possible | Avoids leaking sensitive data during incidents | Compliance issues, breach blast radius | | Email auth passes | SPF, DKIM, DMARC all pass for sending domain | Prevents spoofing and inbox spam flags | Missed invites, phishing risk | | Monitoring active | Uptime checks and error alerts are live before launch | You need signal when review traffic fails | Slow incident response | | Deployment rollback ready | One-click rollback or known safe redeploy path exists | Marketplace reviews expose bad deploys fast | Extended downtime |

A useful threshold: if your app has any critical auth bypasses open to unauthenticated users or any exposed secrets in production artifacts, it fails review readiness immediately.

The Checks I Would Run First

1. Admin route access control

• Signal: I try direct URL hits on admin pages and API endpoints without a valid session.
• Tool or method: Browser incognito session plus curl/Postman against key endpoints.
• Fix path: Add server-side authorization checks on every route and action. Do not rely on hidden UI elements or frontend guards.

2. Session and token handling

• Signal: I inspect whether session cookies are HttpOnly, Secure, SameSite set correctly, and whether tokens are stored in localStorage.
• Tool or method: DevTools Application tab plus response header inspection.
• Fix path: Move sensitive tokens out of localStorage where possible. Use secure cookies for browser sessions and rotate tokens on privilege changes.

3. Secrets exposure scan

• Signal: I search the repo history, env files, build output, logs, and client bundle for keys like API tokens or private URLs.
• Tool or method: grep plus secret scanners such as GitHub secret scanning or gitleaks.
• Fix path: Remove secrets from code immediately. Rotate anything that may have been exposed. Move runtime values into environment variables on the server only.

4. Production transport security

• Signal: HTTP requests redirect to HTTPS with no mixed content warnings. SSL is valid across root domain and subdomains.
• Tool or method: Browser security panel plus curl -I against HTTP and HTTPS URLs.
• Fix path: Force 301 redirects at Cloudflare or the origin. Fix absolute asset URLs so images/scripts do not load over HTTP.

5. Email domain authentication

• Signal: Outbound mail passes SPF/DKIM/DMARC alignment tests.
• Tool or method: MXToolbox plus test sends to Gmail/Outlook headers.
• Fix path: Publish correct DNS records before launch. If marketing emails are sent from the same domain as product alerts, separate subdomains if needed.

6. Monitoring and alerting coverage

• Signal: I can see uptime checks for the main app URL plus alerts for 5xx spikes or failed login flows.
• Tool or method: UptimeRobot/Better Stack/New Relic health checks plus synthetic login tests.
• Fix path: Add at least one external uptime monitor and one error alert channel before marketplace submission.

Red Flags That Need a Senior Engineer

1. You have admin features behind only frontend guards

• If users can still call protected APIs directly after logging out or changing roles, this is not a cosmetic issue. It is a security bug that can fail review fast.

2. You do not know where secrets live

• If API keys exist in multiple places across Lovable exports, Vercel env vars, backend config files, and old commits, DIY cleanup gets risky quickly.

3. The app uses third-party auth or webhooks but has no verification

• Missing signature checks on webhooks is how fake events get accepted. In marketplace products that often means broken billing states or fake admin actions.

4. There is no clear production deployment path

• If deploys depend on manual steps in three dashboards with no rollback plan, one bad release can delay review by days.

5. You cannot explain tenant isolation

• If one customer can ever query another customer's records because filters are "handled in the UI," you need senior-level help now.

DIY Fixes You Can Do Today

1. Run a secret scan

• Search your repo for `.env`, `api_key`, `secret`, `private_key`, `Bearer`, and service-specific tokens.
• Delete anything sensitive from commits you have not shipped yet.
• Rotate any key that ever touched a public repo.

2. Force HTTPS at the edge

• Turn on Cloudflare proxying if you use it.
• Set HTTP to HTTPS redirects everywhere you control.
• Check that your canonical domain matches your SSL certificate exactly.

3. Test the admin area in incognito

• Log out completely.
• Open protected routes directly by URL.
• Try role changes with a low-permission user if you have one.

4. Verify email DNS

• Confirm SPF includes only the services you actually send from.
• Enable DKIM signing with your mail provider.
• Start DMARC at `p=none` if you are unsure so you can observe failures before enforcing policy.

5. Add basic monitoring now

• Create an uptime check for homepage plus login page plus one protected endpoint if possible.
• Add error alerts to Slack or email so failed deployments do not sit unnoticed overnight.

A simple SPF record often looks like this:

v=spf1 include:_spf.google.com include:sendgrid.net ~all

That is only correct if those are truly your sending providers. Do not copy records blindly because bad email DNS causes deliverability problems that look like product bugs during review.

Where Cyprian Takes Over

If any of these fail during my audit window, Launch Ready becomes the fastest path to getting the app through review without dragging your team into infrastructure work.

• Domain setup and DNS cleanup
• Redirects for root domain and subdomains
• Cloudflare configuration
• SSL validation
• Caching rules where safe
• DDoS protection basics
• SPF/DKIM/DMARC setup
• Production deployment verification
• Environment variable audit
• Secrets cleanup guidance
• Uptime monitoring setup
• Handover checklist

How I map failures to delivery:

| Failure found | What I fix | | --- | --- | | Broken HTTP to HTTPS redirect | Domain routing + Cloudflare redirect rules | | Mixed content warnings | Asset URL cleanup + SSL verification | | Exposed env values in frontend build | Secret removal + deployment hardening | | Email failing inbox checks | SPF/DKIM/DMARC DNS records | | No alerting on downtime | Uptime monitor + notification setup | | Unclear handoff process | Deployment notes + reviewer-ready checklist |

My recommendation is simple: if you are within 72 hours of submission and still debugging auth paths or DNS records yourself, stop burning time on trial-and-error fixes. Buy the sprint instead of risking another review delay cycle.
