Launch Ready cyber security Checklist for automation-heavy service business: Ready for production traffic in AI tool startups?.

What "ready" means for Launch Ready

For an automation-heavy service business, "ready for production traffic" does not mean the site is live and looks fine on your laptop. It means a stranger can land on your domain, trust the brand, submit a form, trigger automations, and not expose your customers, inboxes, or backend systems to avoidable risk.

For AI tool startups, I would define ready as this: DNS is correct, email deliverability is passing SPF/DKIM/DMARC, SSL is enforced everywhere, secrets are not exposed in the client or repo, Cloudflare is protecting the edge, deployment is stable, monitoring is alerting you before customers do, and the first 100 to 1,000 visitors do not break onboarding or create support chaos.

If any of these are missing, you are not ready. You are testing in public.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain points correctly | Root and www resolve to the right app with no loops | Users reach the real product | Lost traffic, broken ads, SEO issues | | HTTPS enforced | All pages redirect to HTTPS with valid certs | Protects sessions and trust | Browser warnings, login failures | | SPF/DKIM/DMARC pass | All three authenticate and DMARC has policy | Prevents spoofing and improves delivery | Emails land in spam or get blocked | | Secrets are server-side only | No API keys in frontend bundle or public repo | Stops key theft and abuse | Billing spikes, data leaks | | Cloudflare active | WAF, DDoS protection, caching enabled where safe | Reduces attack surface and load | Outages from bots or traffic spikes | | Redirects are clean | Old URLs map once with no chains > 1 hop | Preserves conversions and SEO | Broken funnels and slow load times | | Subdomains are isolated | App, auth, API, and marketing domains have clear roles | Limits blast radius | Cross-subdomain exposure | | Monitoring works | Uptime checks plus error alerts fire within 5 minutes | You catch failures early | Silent downtime and missed sales | | Deployment is reproducible | One command or pipeline deploys same build every time | Prevents "works on my machine" risk | Broken releases and rollback pain | | Handover is complete | Owner has checklist for DNS, email, secrets, rollback | Keeps ops from depending on one person | Support bottlenecks and delayed fixes |

The Checks I Would Run First

1. DNS and domain routing

Signal: the root domain, www subdomain, app subdomain, and any API or auth subdomains resolve exactly where they should. There should be no redirect chain longer than one hop.

Tool or method: I would check DNS records in Cloudflare or your registrar panel, then test with `dig`, browser dev tools, and a redirect checker. I also verify that old domains or campaign URLs do not create loops.

Fix path: point all public entry points to the intended origin or Cloudflare target. Then set a single canonical URL strategy: usually `https://www` or `https://app`, but not both competing. If redirects are messy now, I would fix them before you spend another dollar on ads.

2. SSL enforcement and certificate health

Signal: every public page loads over HTTPS with no mixed content warnings. Certificate renewal should be automatic and visible in monitoring.

Tool or method: I check browser console warnings, run an SSL test like SSL Labs if needed, and inspect whether Cloudflare SSL mode matches your origin setup. I also confirm HSTS only after everything is stable.

Fix path: force HTTPS at the edge and origin where appropriate. Replace hardcoded `http://` assets and webhook callbacks. If you have mixed content on checkout or login pages, that is a conversion killer because browsers will block parts of the page.

3. Secrets exposure review

Signal: there are zero exposed API keys in frontend code, public GitHub repos, build logs, shared docs, or deployed environment dumps. Any secret that can access payments, email sending, databases, or AI APIs must stay server-side.

Tool or method: I scan the repo history plus deployed bundle for keys using secret scanners like GitHub secret scanning or tools such as Gitleaks. I also inspect browser network calls to see whether sensitive tokens are being shipped to users.

Fix path: rotate anything exposed immediately. Move secrets into environment variables on the host platform or secret manager. If your frontend needs to call third-party services directly today because "it was faster," that is exactly how startups get billed for abuse they did not cause.

4. Email authentication and deliverability

Signal: SPF passes for your sending provider, DKIM signs outgoing mail correctly, and DMARC is at least set to `quarantine` after testing alignment. Transactional emails should reliably hit inboxes rather than spam.

Tool or method: I use MXToolbox-style checks plus real test sends to Gmail and Outlook accounts. I verify that password resets, onboarding emails, invoices, and notifications all come from approved infrastructure.

Fix path:

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

That kind of record is only an example; I would tailor it to your actual mail provider stack. The fix path is usually simple technically but high impact commercially because failed delivery creates support tickets fast.

5. Cloudflare edge protections

Signal: Cloudflare proxying is active where it should be active; WAF rules exist; bot traffic can be challenged; caching is enabled for static assets; DDoS protection is on by default.

Tool or method: I inspect Cloudflare dashboard settings plus request headers from a live request. I also review whether cache rules accidentally cache private pages like dashboards or authenticated responses.

Fix path: keep marketing pages cacheable but never cache user-specific data unless you know exactly what you are doing. Add rate limits on login forms, signup endpoints, password reset routes, contact forms with automations behind them.

6. Monitoring and rollback readiness

Signal: uptime checks ping critical endpoints every minute; error alerts go to email/Slack/SMS; deployment has a rollback path; p95 API latency stays under 500ms for core actions during normal load.

Tool or method: I set up synthetic checks for homepage load, login flow health endpoints if available), form submission success rate), plus application logs and error tracking like Sentry. For performance-sensitive paths I watch p95 latency rather than averages because averages hide pain.

Fix path: define alert thresholds before launch so you do not argue with reality later. If a checkout form fails more than 2 times in 100 submissions or login errors spike above 1 percent for 10 minutes , rollback immediately instead of "waiting to see."

Red Flags That Need a Senior Engineer

1. You have secrets in frontend code already. If an API key can be copied from DevTools in under 60 seconds , assume it will be abused sooner rather than later.

2. Your automation platform can trigger customer-facing actions without strong auth. This often turns into accidental sends , duplicate charges , bad data writes , or unauthorized access across systems.

3. You cannot explain which domain handles what. If marketing , app , auth , webhooks , admin , and email sending all blur together , one misconfig can take down everything at once.

4. Your deployment process depends on manual steps. Manual deploys are where broken env vars , missed migrations , partial builds , and forgotten rollbacks happen.

5. You already had one "small" outage. One outage before launch usually means hidden coupling somewhere in DNS , auth , secrets , queue jobs , webhooks , or caching .

DIY Fixes You Can Do Today

1. Turn on Cloudflare proxying for public assets. Keep static marketing pages behind the orange cloud where safe . Do not proxy private admin endpoints blindly if you do not understand cache behavior .

2. Rotate any key that has been shared in screenshots , chats , repos , or browser code. This includes OpenAI keys , Stripe keys , database passwords , webhook signing secrets , SMTP credentials .

3. Add SPF DKIM DMARC records now. Even a basic policy beats none . Start with monitoring if you are unsure about enforcement .

4. Remove hardcoded URLs. Search for `http://`, old staging domains , localhost callbacks , webhook URLs pointing at dead environments .

5 . Set up two alerts today. One uptime check for homepage /health if you have it . One error alert from your app logs or Sentry so you hear about broken flows before users flood support .

Where Cyprian Takes Over

• Domain setup and clean redirects
• Subdomain mapping for app , auth , api , marketing
• Cloudflare configuration including SSL , caching , DDoS protection , basic WAF posture
• SPF DKIM DMARC setup verification
• Production deployment validation
• Environment variable review and secret handling cleanup
• Uptime monitoring setup
• Handover checklist so your team can own it after launch

My order of operations is simple:

1 . Audit first . 2 . Fix anything that can expose data , break delivery , or stop traffic . 3 . Validate with live tests . 4 . Hand over a checklist you can actually use .

If the product is already getting paid traffic but feels fragile , this sprint reduces launch risk faster than trying to patch issues ad hoc over several weekends . That saves support hours , protects conversion rate ,and avoids embarrassing downtime during campaigns .
