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

What "ready" means for Launch Ready

For this product, "ready" means a customer can open your mobile-first app, sign up, verify their email, and complete onboarding without hitting broken DNS, failed SSL, blocked emails, missing secrets, or a dead production deploy.

I would call it ready only if the basics are true in production: domain resolves correctly, HTTPS is enforced, SPF/DKIM/DMARC pass, no secrets are exposed in the client or repo, uptime monitoring is live, and the onboarding path works on a phone without layout breakage or auth failures. If any one of those fails, you do not have a launch problem only - you have a support load problem, a trust problem, and usually a conversion problem.

For an automation-heavy service business, the risk is sharper. These apps often depend on webhooks, third-party APIs, background jobs, and email triggers, which means one bad config can break customer onboarding across the whole funnel. I would treat "ready" as: no critical auth bypasses, zero exposed secrets, p95 API latency under 500ms for onboarding endpoints, and email deliverability verified before traffic goes live.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain DNS | Root and www resolve to the correct app within 60 seconds globally | Customers must reach the app reliably | Dead links, wrong environment, lost signups | | SSL/TLS | HTTPS valid on all public routes with no mixed content | Protects login and onboarding data | Browser warnings, blocked forms, trust loss | | Redirects | One canonical URL path for root, www, and subdomains | Prevents duplicate indexing and broken flows | SEO issues, login loops, confused users | | Email auth | SPF, DKIM, and DMARC all pass | Onboarding emails must land in inboxes | Verification emails go to spam or fail | | Secrets handling | Zero secrets in client code or public repos | Stops credential theft and abuse | Data exposure, API charges, account takeover | | Cloudflare config | WAF/CDN/DDoS protections active with sane rules | Shields launch traffic from abuse | Downtime from bots or spikes | | Deployment safety | Production deploy is repeatable and rollback-ready | Avoids launch-day surprises | Broken release with no recovery path | | Monitoring | Uptime alerts and error alerts are live | You need to know before customers complain | Silent outage and delayed response | | Mobile onboarding UX | Signup flow works on iPhone and Android at common sizes | Most customers will start on mobile first | Drop-off during signup and verification | | Access control | Admin tools are locked down with least privilege | Reduces blast radius if credentials leak | Full system compromise from one account |

The Checks I Would Run First

1. DNS points to exactly one production target

Signal: `launchready.com` and `www.launchready.com` should resolve to the intended production host only. There should be no stale A records pointing at old servers or preview environments.

Tool or method: I would check DNS propagation with `dig`, `nslookup`, Cloudflare DNS logs, and a quick browser test from mobile data. If you have multiple subdomains for onboarding or app access, I would confirm each one has an owner and purpose.

Fix path: Remove stale records, set canonical redirects at the edge or app layer, and document which subdomain serves marketing versus app traffic. If you are launching today with old records still active, that is not a minor cleanup - it is how users end up on dead pages.

2. HTTPS is valid everywhere with no mixed content

Signal: Every public page loads over HTTPS with a valid certificate chain. No form posts or API calls should downgrade to HTTP.

Tool or method: I would use browser dev tools plus SSL Labs to check cert validity and mixed content warnings. On mobile-first apps I also test in Safari iOS because it catches issues that desktop Chrome hides.

Fix path: Force HTTPS at Cloudflare or your host, renew certs automatically, and replace any hardcoded `http://` assets or webhook URLs. If login pages still show browser warnings after deployment, do not launch.

3. SPF/DKIM/DMARC pass before onboarding emails go out

Signal: Verification emails land in inboxes instead of spam folders. Your domain should have SPF authorized senders configured correctly, DKIM signing enabled for your mail provider, and DMARC set to at least `p=none` during validation before moving toward stricter policy.

Tool or method: I would use MXToolbox plus a real inbox test across Gmail and Outlook. Then I would send actual onboarding messages through the same provider your app uses in production.

Fix path: Add the exact DNS records your mail provider requires and confirm alignment with the sending domain. If users cannot verify their account because mail never arrives, your funnel stops at step one.

4. Secrets are not exposed in client bundles or public repos

Signal: No API keys, webhook secrets, private tokens, `.env` values, or service credentials appear in frontend code, build output files, Git history snapshots meant for public access paths.

Tool or method: I would scan the repo with secret search tools like Gitleaks or TruffleHog plus a manual review of build artifacts. Then I would inspect network requests from the mobile web app to make sure sensitive calls happen server-side where possible.

Fix path: Move secrets into environment variables on the server only, rotate anything already exposed, and revoke old keys immediately. If you have ever pasted a live key into Lovable prompts or shared code exports publicly by accident, assume it is compromised until proven otherwise.

5. Production deploy can be rolled back in under 10 minutes

Signal: A bad release can be reverted quickly without manual surgery. You need one known-good version ready to redeploy.

Tool or method: I would test rollback by actually doing it once in staging or during a controlled window. Then I would verify logs show which commit is live and whether migrations are reversible.

Fix path: Keep migrations backward compatible for at least one release window and avoid destructive schema changes on launch day. If rollback takes hours instead of minutes there is too much business risk to self-manage.

6. Uptime monitoring catches failures before customers do

Signal: You receive alerts for downtime,, failed health checks,, expired certs,, broken webhook endpoints,, or elevated error rates within minutes.

Tool or method: I would set up UptimeRobot or Better Stack plus application error monitoring like Sentry. For an automation-heavy service business I also want alerting on background job failures because those often break onboarding silently.

Fix path: Add health endpoints,, alert routing to email plus Slack,, and simple runbooks for common incidents. If nobody gets paged when signup breaks at midnight,, your support inbox becomes your monitoring system.

Red Flags That Need a Senior Engineer

1. You have multiple third-party automations tied into onboarding. One broken webhook can stop account creation,, provisioning,, billing,, and welcome emails at once.

2. Secrets were ever stored in frontend code,, shared exports,, or prompt history. Once credentials leak,, cleanup means rotation,, audit,, revocation,, and sometimes customer notification.

3. You cannot explain which system sends email. If you do not know whether SendGrid,, Postmark,, Resend,, Google Workspace,, or something else handles delivery,,, you cannot debug deliverability fast enough for launch.

4. Your deploy process depends on manual steps. Manual deploys fail under pressure because someone misses an env var,,, uses the wrong branch,,, or skips migration order.

5. Mobile signup has more than two failure points. If signup requires scrolling through tiny inputs,,, modal stacking,,, SMS/email verification,,, then billing setup,,, you need someone who can reduce drop-off without creating security gaps.

DIY Fixes You Can Do Today

1. Audit your public URLs. Open root,,, www,,, app subdomain,,, login,,, signup,,, forgot password,,, and webhook callback URLs on mobile data plus Wi-Fi. Fix any redirect chains longer than one hop.

2. Check email authentication. Use MXToolbox to confirm SPF,,, DKIM,,, DMARC are passing for your sending domain before you invite customers into onboarding.

3. Rotate anything suspicious. If an API key was ever visible in screenshots,,, chat logs,,, frontend code,,, or AI prompts,,,, revoke it now and replace it everywhere it was used.

4. Turn on basic monitoring. Set uptime checks on homepage,,,, auth endpoint,,,, health endpoint,,,,and payment page if relevant., Then add error alerts so failed logins do not sit unnoticed for hours.

5. Test onboarding on an actual phone. Use Safari iPhone and Chrome Android., Complete signup as a new user., Watch for keyboard overlap,,,, broken buttons,,,, tiny tap targets,,,,and email verification delays., Fix those before spending more on ads.
