Launch Ready cyber security Checklist for automation-heavy service business: Ready for scaling past prototype traffic in mobile-first apps?

"Ready" does not mean "it works on my phone." For an automation-heavy service business, ready means a stranger can land on your domain, trust the brand, sign up, receive emails, trigger automations, and hit the app without exposing secrets, breaking auth, or creating support tickets.

For a mobile-first app scaling past prototype traffic, I want to see 5 things before I call it launch ready:

• Domain and email are correctly authenticated.
• The app is deployed behind Cloudflare with SSL and sane caching.
• Secrets are not in code, logs, or client bundles.
• Monitoring is live, so failures are visible within minutes.
• Basic abuse controls exist for login, forms, webhooks, and public endpoints.

If any of those are missing, you do not have a launch problem. You have a security and operations problem that will show up as downtime, failed onboarding, broken email delivery, or exposed customer data. That is expensive when paid traffic starts hitting the product.

Here is the standard I use: zero exposed secrets, SPF/DKIM/DMARC passing, no critical auth bypasses, and p95 API latency under 500ms on the core user journey. For mobile-first apps, I also want Lighthouse performance above 85 on key landing pages and no broken flows on iPhone-sized screens.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain DNS | A/AAAA/CNAME records resolve correctly in all target regions | Users must reach the right app and marketing pages | Wrong site loads, intermittent outages | | SSL/TLS | HTTPS enforced with valid certs and redirect from HTTP | Protects logins and forms in transit | Browser warnings, lost trust, weaker security | | Email auth | SPF, DKIM, and DMARC all pass | Prevents spoofing and improves deliverability | Emails land in spam or get rejected | | Cloudflare edge | Proxy enabled with WAF/DDoS protection where needed | Reduces attack surface at the edge | More bot traffic, more downtime risk | | Deployment hygiene | Production deploy is repeatable and documented | Avoids manual mistakes during launch | Broken releases and rollback delays | | Secrets handling | Zero secrets in repo or client-side code | Prevents account takeover and data leaks | Exposed API keys, billing abuse | | Redirects/subdomains | Canonical redirects work for www/non-www/app/api | Keeps SEO clean and routes users correctly | Duplicate content, broken auth callbacks | | Monitoring | Uptime checks plus error alerts are active | You need to know when launch breaks something | Silent failures and support chaos | | Rate limiting | Public endpoints have basic abuse controls | Stops brute force and form spam | Cost spikes and login abuse | | Handover checklist | Owner knows DNS provider, deploy path, rollback steps | Launches fail when nobody owns the system | Slow recovery after incidents |

The Checks I Would Run First

1. Domain resolution and canonical routing Signal: `www`, root domain, app subdomain, and API subdomain all resolve to the intended targets with no loops. Tool or method: `dig`, browser checks from mobile Safari and Chrome, plus a DNS propagation checker. Fix path: I would clean up records first, then set one canonical domain strategy. If you need both `www` and root to work, I would choose one as canonical and 301 redirect the other.

2. Email authentication for transactional delivery Signal: SPF passes once per sending service, DKIM signs outbound mail, and DMARC is set to at least `p=quarantine` after testing. Tool or method: MXToolbox or Google Postmaster Tools plus test sends to Gmail and Outlook. Fix path: I would align your sender domain with your mail provider before launch. If email fails here, onboarding emails will vanish into spam or be rejected entirely.

3. Secret exposure review Signal: No API keys in Git history, frontend bundles, build logs, issue trackers, or serverless function outputs. Tool or method: secret scanning in GitHub/GitLab plus a repo grep for common key patterns. Fix path: rotate anything exposed immediately. Then move all sensitive values into environment variables or a secret manager.

4. Edge security at Cloudflare Signal: Origin IP is hidden where possible; WAF rules block obvious bots; SSL mode is strict; DDoS protection is enabled. Tool or method: Cloudflare dashboard review plus origin header inspection. Fix path: I would force HTTPS at the edge and make sure origin access is restricted so attackers cannot bypass Cloudflare by hitting your server directly.

5. Production deployment repeatability Signal: A fresh deploy can be done by following documented steps without tribal knowledge. Rollback exists. Tool or method: dry run deployment checklist plus a staging-to-prod comparison. Fix path: I would remove manual clicks from critical release steps. If deployment only works when one person remembers five hidden settings, it is not production safe.

6. Monitoring coverage for user-facing paths Signal: uptime monitor checks home page plus signup/login endpoint; error alerts route to email or Slack; p95 response time is tracked for core APIs. Tool or method: UptimeRobot/Pingdom/Sentry/Datadog depending on stack. Fix path: I would add alerting before adding more features. If you cannot see failures within 5 minutes of release day traffic starting to hit the app, you are flying blind.

Red Flags That Need a Senior Engineer

1. Your app works only when one specific person deploys it manually. That means release risk is concentrated in tribal knowledge instead of process.

2. Secrets are stored in `.env` files that have been shared around Slack or committed before. I would treat that as an incident until proven otherwise because leaked keys become real cost fast.

3. Email deliverability is already shaky before scale starts. If onboarding emails fail now with 20 users per day, they will become a conversion leak at 200 users per day.

4. The app uses multiple auth providers but has no clear session ownership model. That creates account confusion, broken password resets, and support load you do not want during growth.

5. You cannot answer who owns DNS changes if the site goes down tonight. That usually means no rollback plan either.

DIY Fixes You Can Do Today

1. Turn on two-factor authentication everywhere important. Start with domain registrar, hosting platform, Cloudflare, email provider, GitHub/GitLab, Stripe-like billing tools if relevant.

2. Scan your repo for secrets right now. Search for API keys using simple patterns like `sk_`, `pk_`, `AIza`, private tokens inside frontend code.

3. Verify your email records before sending another campaign or onboarding flow message. Use MXToolbox to check SPF/DKIM/DMARC status and fix any failures first.

4. Force HTTPS across the entire site with one canonical redirect rule set.

server {
  listen 80;
  server_name example.com www.example.com;
  return 301 https://example.com$request_uri;
}

5. Add at least one uptime check today for home page plus login or signup endpoint. If you do nothing else this week, make failure visible within 1 minute instead of discovering it from customers.

Where Cyprian Takes Over

I take over the parts that usually cause launch delays or silent security failures:

• DNS cleanup and canonical routing if domains are misconfigured.
• Email authentication setup for SPF/DKIM/DMARC.
• Cloudflare configuration including SSL enforcement,

caching rules, basic DDoS protection, and safer origin exposure.

• Production deployment so the app goes live without guesswork.
• Environment variable setup so secrets stay out of code.
• Monitoring setup so downtime becomes visible quickly.
• Handover checklist so you know what was changed,

where it lives, and what to do next if something breaks.

My order of operations is simple:

1. Hour 0 to 8: audit domain, email, hosting, and current risk points. 2., Hour 8 to 24: fix DNS, SSL, redirects, and secret handling. 3., Hour 24 to 36: deploy production, verify mobile flows, and test key automations. 4., Hour 36 to 48: add monitoring, run final checks, and hand over a clear launch doc.

If the checklist fails because of missing records, broken auth mail, or unclear deployment ownership, this service is cheaper than losing a week debugging it yourself while ads keep spending money into a broken funnel.
