Launch Ready cyber security Checklist for automation-heavy service business: Ready for paid acquisition in mobile-first apps?.

What "ready" means for Launch Ready

For an automation-heavy service business, "ready for paid acquisition" means a stranger can land on your mobile-first app, trust the brand, sign up or book, and not hit a security or delivery failure that kills conversion.

I would call it ready only if these are true:

• Domain resolves correctly on every key subdomain.
• SSL is valid everywhere, with no mixed content.
• Email deliverability is working, with SPF, DKIM, and DMARC passing.
• Production deploys are repeatable and secrets are not exposed in code or logs.
• Cloudflare is protecting the app from basic abuse and DDoS noise.
• Monitoring alerts you before customers do.
• Mobile UX loads fast enough to support paid traffic, with LCP under 2.5s on common pages.
• There are no critical auth bypasses, open admin routes, or public automation endpoints that can be abused.

If any of those fail, paid acquisition becomes expensive damage control. You do not just lose leads; you waste ad spend, create support load, and invite account takeovers or data exposure.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain ownership | Root domain and subdomains point to the right app and services | Traffic must reach the correct product | Wrong site, broken onboarding, lost trust | | SSL everywhere | No mixed content, valid certs on all routes | Users and browsers expect encrypted transport | Browser warnings, blocked requests, lower conversion | | Email auth | SPF, DKIM, DMARC all pass | Service emails must land in inboxes | Password resets and receipts go to spam | | Secrets handling | Zero secrets in repo, client bundle, logs, or tickets | Exposed credentials become instant incidents | Data leaks, unauthorized access, vendor abuse | | Auth controls | No public admin paths or auth bypasses | Paid traffic will find weak spots fast | Account takeover, abuse of automation flows | | Rate limiting | Login, signup, forms, and APIs have limits | Automation-heavy apps attract bots quickly | Spam signups, cost spikes, downtime | | Cloudflare setup | WAF/DDoS rules active for public surface area | First line of defense against noisy attacks | Origin overload, scraping, basic exploit attempts | | Deployment safety | Production deploy is repeatable with rollback path | Launch day failures need quick recovery | Broken release blocks acquisition campaigns | | Monitoring coverage | Uptime and error alerts are active with clear ownership | You need to know before customers complain | Long outages, missed incidents | | Mobile performance | Key pages hit LCP under 2.5s and CLS stays low | Paid traffic converts worse on slow mobile pages | Bounce rate rises and CAC gets worse |

The Checks I Would Run First

1. Domain and DNS integrity

• Signal: Root domain works. www redirects correctly. Subdomains like app., api., mail., and dashboard. resolve as intended.
• Tool or method: `dig`, `nslookup`, browser checks in incognito mode, Cloudflare DNS review.
• Fix path: I would clean up records first: one canonical domain, one redirect rule set, then verify every subdomain used by email or automation. If the wrong origin is exposed, I would move traffic behind Cloudflare before launch.

2. SSL and mixed content audit

• Signal: No browser certificate warnings. No images, scripts, webhooks, or API calls loading over HTTP.
• Tool or method: Chrome DevTools Security tab, Lighthouse audit, `curl -I https://...`.
• Fix path: I would force HTTPS at the edge and update hardcoded links in app config and templates. Mixed content is a conversion killer because mobile browsers are less forgiving.

3. Email authentication and deliverability

• Signal: SPF includes only approved senders. DKIM signs outbound mail. DMARC policy is at least `quarantine` after testing.
• Tool or method: MXToolbox or Google Admin Toolbox checkers; send test mail to Gmail and Outlook.
• Fix path: I would align DNS records with the actual provider used by your app or automation stack. If password resets or invoices fail here during paid acquisition, support tickets spike immediately.

4. Secrets exposure review

• Signal: No API keys in Git history, frontend bundles, logs, screenshots, or pasted docs.
• Tool or method: Secret scanning in GitHub/GitLab plus manual grep for keys like `sk_`, `pk_`, `x-api-key`, service tokens.
• Fix path: I would rotate anything exposed before launch. In a service business with automations connected to third-party tools, one leaked key can trigger billing abuse or customer data access.

5. Auth and authorization boundaries

• Signal: A logged-out user cannot hit admin routes; a normal user cannot access another user's records; webhook endpoints validate signatures.
• Tool or method: Manual role testing in browser plus Postman/Insomnia requests against protected endpoints.
• Fix path: I would verify server-side authorization on every sensitive action. Do not trust hidden buttons or frontend route guards alone.

6. Rate limits and abuse controls

• Signal: Signup forms do not accept unlimited submissions from one IP/device; login has throttling; automation endpoints have quotas.
• Tool or method: Basic load test plus repeated form submissions from one IP and multiple user agents.
• Fix path: I would add rate limits at the edge and app layer. For mobile-first paid traffic funnels this matters because bots often target high-conversion forms first.

limit_req_zone $binary_remote_addr zone=api_limit:10m rate=5r/s;

location /api/ {
  limit_req zone=api_limit burst=20 nodelay;
}

That snippet is not the whole solution. It is only useful if you also protect login flows, webhook handlers with signature checks,and sensitive actions with authorization checks.

Red Flags That Need a Senior Engineer

1. You have multiple tools sending emails but no clear sender identity strategy. That usually means inbox placement will be unstable when volume increases.

2. Your app uses third-party automations that can trigger payments,data syncs,and customer notifications without strong validation. One malformed payload can create duplicate charges or bad customer records.

3. Secrets live in `.env` files shared across teammates or copied into deployment dashboards manually. This creates invisible risk until someone leaks access.

4. Your production deploy depends on "remembering steps" instead of an auditable process. That is how launches fail at 10 pm when ads are already running.

5. You cannot explain who gets alerted when uptime drops below 99.9% or when error rate crosses 2%. If nobody owns incidents,you will hear about them from customers first.

DIY Fixes You Can Do Today

1. Turn on Cloudflare for the public site

Put the main domain behind Cloudflare now if it is not already there. Enable HTTPS-only mode,DDoS protection,and basic WAF rules for obvious bot traffic.

2. Verify email DNS records

Check SPF,DKIM,and DMARC with your email provider's setup guide.

3. Rotate obvious secrets

Search your repo for API keys,test tokens,and webhook secrets today. Rotate anything that has been pasted into chats,screenshots,and shared docs.

4. Audit mobile landing pages

Test your top three pages on an actual phone over cellular data. If LCP feels slow,pair down hero media,reduce scripts,and compress images before spending on ads.

5. Add basic monitoring

Set uptime alerts,email error alerts,and a simple status check for login,page load,and checkout/bookings flows. Even a 99% uptime service loses credibility fast if failures go unseen for hours.

Where Cyprian Takes Over

If you have any of these failures,I would not treat them as "small fixes." They map directly to Launch Ready deliverables because they affect launch safety,revenue capture,and support burden.
