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

"Ready" for an internal admin app is not the same as "it works on my machine." For a marketplace product running paid acquisition, ready means the app can handle real traffic, protect customer and operator data, survive common attack paths, and not break the first time a paid lead lands.

I would call it launch ready only if these are true:

• No exposed secrets in code, logs, or client bundles.
• Authentication is enforced on every admin route and API.
• Authorization is role-based, not just "logged in equals allowed."
• Domain, email, SSL, and redirects are correct so trust signals do not fail.
• Cloudflare, caching, and basic DDoS protection are in place before ads go live.
• Monitoring exists for uptime, errors, and failed logins.
• SPF, DKIM, and DMARC all pass so outbound email does not land in spam.
• p95 API response time is under 500ms for normal admin actions.
• The app has a handover checklist so the founder is not guessing after launch.

For marketplace products, I care about one extra thing: if you buy traffic tomorrow, will the app create support load, security risk, or broken onboarding? If yes, it is not ready.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Auth on all admin routes | Every page and API requires valid session or token | Stops public access to internal tools | Data exposure, account takeover | | Role-based authorization | Users only see actions allowed by role | Prevents staff from doing too much | Unauthorized edits or deletions | | Secrets handling | Zero secrets in repo or frontend bundle | Keeps keys out of attackers' hands | Breach of DBs, email, payments | | SSL and redirects | HTTPS only, one canonical domain | Trust and browser security checks | Mixed content, login failure | | Cloudflare protection | WAF/rate limiting/CDN enabled | Reduces attack surface and load | Bot abuse, downtime spikes | | SPF/DKIM/DMARC | All pass for sending domain | Keeps transactional mail deliverable | Emails land in spam or fail | | Input validation | Server validates all writes and uploads | Blocks injection and bad data | Corruption, RCE risk, broken records | | Logging and monitoring | Errors + uptime alerts active | Lets you detect issues fast | Silent failures during ad spend | | Backup and rollback plan | Recent backup plus deploy rollback path | Limits blast radius of bad deploys | Long outages and data loss | | Performance baseline | p95 API under 500ms on core flows | Paid traffic needs fast admin ops too | Slow ops, support delays, churn |

The Checks I Would Run First

1. Authentication coverage

Signal: Any admin page or endpoint that loads without a valid session is a release blocker. I also check whether auth is only on the frontend, because that is fake security.

Tool or method: Browser session test plus direct API calls with curl/Postman. I try private routes without cookies and with expired tokens.

Fix path: Move auth checks to the server layer first. Then add middleware for pages so users get redirected before sensitive data renders.

2. Authorization by role

Signal: A user with a basic role can reach delete buttons, export endpoints, billing settings, or user management screens.

Tool or method: Test at least three roles manually: owner, staff member, read-only user. I look at both UI visibility and backend enforcement.

Fix path: Add explicit permission checks per action. Do not trust hidden buttons alone. If the backend does not reject forbidden requests with 403s, the fix is incomplete.

3. Secret exposure scan

Signal: API keys, database URLs, webhook secrets, or OAuth client secrets appear in Git history, environment files committed to repo history, frontend JS bundles, logs, or error pages.

Tool or method: Search repo history plus bundle inspection. I also check deployment env vars and CI logs.

Fix path: Rotate anything exposed immediately. Move secrets into platform env vars or secret managers. Remove them from client code entirely unless they are meant to be public identifiers.

4. Email trust setup

Signal: SPF/DKIM/DMARC are missing or failing for your domain. Marketplace products often depend on login links, invites, receipts, alerts, and password resets.

Tool or method: DNS lookup plus mailbox tests to Gmail and Outlook. I verify headers show aligned authentication results.

Fix path: Publish correct DNS records and test again after propagation. If your sender platform supports it badly configured by default happens often - I recheck alignment before launch.

5. Edge protection and rate limiting

Signal: Login forms can be brute forced without friction; public endpoints accept unlimited requests; bots can hammer search or invite flows.

Tool or method: Cloudflare dashboard review plus simple request bursts from a test client. I inspect logs for repeated failed attempts.

Fix path: Turn on WAF rules where appropriate. Add rate limits to login, password reset, invite creation, export jobs, and any expensive write endpoint.

6. Monitoring and rollback readiness

Signal: You cannot answer "how do we know it broke?" within 60 seconds. There is no alerting for uptime failures or error spikes.

Tool or method: Check uptime monitor status page setup plus app error tracking such as Sentry. Confirm deploy rollback steps before release day.

Fix path: Add uptime alerts to email plus Slack if available. Keep one-click rollback ready. If deploys cannot be reversed cleanly within 10 minutes that is a launch risk.

Red Flags That Need a Senior Engineer

1. You have auth logic split across frontend guards only.

That means anyone who knows the URL may still hit sensitive APIs directly.

2. The app stores secrets in `.env` files that were already committed.

At that point you need rotation work plus history cleanup guidance fast.

3. Admin actions do not have audit logs.

If something goes wrong during paid acquisition you will not know who changed what.

4. The deployment process is manual and undocumented.

One missed step can take down login links or break production config during launch week.

5. You see weird behavior under light load already.

If an internal tool slows down now it will get worse when traffic comes from ads or partners.

DIY Fixes You Can Do Today

1. Run a quick secret sweep

Search your repo for `api_key`, `secret`, `password`, `private_key`, `token`, and service names like Stripe or OpenAI. Rotate anything suspicious before asking for help.

2. Verify HTTPS everywhere

Open the site on both `http://` and `https://`. Force one canonical version with redirects so login sessions are not split across domains.

3. Test three user roles manually

Log in as owner-like access if possible then as limited staff then as read-only user if available. Try to open delete pages directly instead of trusting menus.

4. Confirm email authentication

Send yourself a password reset or invite email to Gmail and inspect whether SPF/DKIM/DMARC pass. If they fail now your acquisition emails will underperform later.

5. Add basic uptime monitoring

Set up one monitor for homepage availability plus one for login if possible. A simple alert beats finding out from angry users at 9 am Monday morning.

Where Cyprian Takes Over

If your checklist shows failures in any of these areas - secrets exposure, missing auth enforcement, broken DNS/email, no Cloudflare protection, or no monitoring - that is where I step in with Launch Ready.

What you get in the 48 hour sprint:

• DNS cleanup and redirect fixes
• Subdomain setup
• Cloudflare configuration
• SSL verification
• Caching rules
• DDoS protection basics
• SPF/DKIM/DMARC setup
• Production deployment review
• Environment variable cleanup
• Secrets handling review
• Uptime monitoring setup
• Handover checklist

How I would map failures to deliverables:

| Failure found | Launch Ready deliverable | Timeline | |---|---|---| | Exposed secrets | Rotate keys + move to secure env vars + remove leaks from repo history where possible | Hours 1-6 | | Broken HTTPS or redirects | Canonical domain fix + SSL validation + redirect rules | Hours 1-8 | | Missing email auth records | SPF/DKIM/DMARC DNS setup + mailbox verification tests | Hours 4-12 | | Weak edge protection | Cloudflare hardening + caching + rate limit rules + DDoS basics | Hours 6-18 | | Unsafe production deploys | Deployment review + config cleanup + rollback notes | Hours 12-24 | | No monitoring/handover process | Uptime monitors + alert routing + handover checklist docs | Hours 18-48 |

My recommendation is simple: if paid acquisition starts soon and any of these controls are missing today, do not spend another week patching blindly yourself.
