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

What "ready" means for Launch Ready

For this product, "ready" does not mean the app is polished. It means a mobile-first service business can go live without exposing customer data, breaking email delivery, or creating avoidable downtime on day one.

I would call it ready only if a founder can answer yes to all of these:

• The domain points to the right production app.
• SSL is valid everywhere, including subdomains.
• Cloudflare is protecting the site and not breaking login or checkout flows.
• Production secrets are not in the repo, build logs, or client-side code.
• Email authentication passes SPF, DKIM, and DMARC.
• Redirects are correct and do not create loops or broken deep links.
• Monitoring alerts fire before customers complain.
• The deployment can be rolled back in under 10 minutes.
• No critical auth bypasses, exposed admin routes, or open storage buckets exist.
• Mobile users can load the core page in under 2.5s LCP on a normal 4G connection.

If any one of those fails, launch is not ready. For an automation-heavy service business, the risk is not just "technical debt". It is lost leads, failed email delivery, broken onboarding, support tickets, and paid traffic leaking money into a broken funnel.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain DNS | A and CNAME records resolve correctly within 60 seconds | Users must reach the right app and landing page | Wrong site loads, launch traffic lands on 404s | | SSL | HTTPS valid on apex and subdomains with no mixed content | Browsers trust the site and login forms stay secure | Warning screens, blocked forms, lower conversion | | Redirects | One-hop redirects only; no loops; canonical URLs set | Mobile users need fast navigation and clean indexing | Broken deep links, SEO loss, app handoff issues | | Cloudflare | WAF active, DDoS protection on, no false blocks on auth routes | Protects against abuse and launch-day spikes | Login failures, blocked customers, downtime | | Email auth | SPF, DKIM, DMARC all pass for production domain | Ensures transactional and onboarding emails arrive | Missed OTPs, lost receipts, spam folder delivery | | Secrets handling | Zero exposed secrets in repo, frontend bundle, logs | Prevents account takeover and vendor abuse | Data breach risk, API spend theft | | Deployment | Production build deploys from main branch with rollback path | Reduces release mistakes during launch window | Broken release freezes sales activity | | Environment vars | All required vars documented and set per environment | Prevents runtime crashes after deploy | Blank pages, failed webhooks, dead automations | | Monitoring | Uptime checks plus error alerts plus log access configured | Issues are caught before customers report them | Long outages, support overload | | Mobile performance | LCP under 2.5s and INP under 200ms on core page | Mobile-first users convert poorly when slow or janky | Higher bounce rate and wasted ad spend |

The Checks I Would Run First

1. Domain ownership and DNS correctness

Signal: the root domain resolves to the production app in all target regions without stale records or conflicting providers.

Tool or method: I check registrar records, Cloudflare DNS zone settings if used as proxy layer, and test resolution with `dig`, `nslookup`, and browser-based checks from at least two regions.

Fix path: remove duplicate A/AAAA/CNAME records that conflict with your host. Then set a single source of truth for DNS so marketing pages, app subdomains, and email sending domains do not drift apart.

2. SSL coverage across apex and subdomains

Signal: every public route returns valid HTTPS with no certificate warnings and no mixed-content errors in browser dev tools.

Tool or method: I run SSL Labs style checks plus a browser audit on mobile view. I also inspect console warnings because one insecure image or script can undo the whole setup.

Fix path: issue certificates for apex plus required subdomains. Force HTTPS at the edge only after redirect logic is tested so you do not create loops between host rules and application middleware.

3. Email deliverability setup

Signal: SPF includes only approved senders; DKIM signs outbound mail; DMARC policy is present with alignment passing.

Tool or method: I inspect DNS TXT records and send test messages to Gmail and Outlook to confirm headers pass authentication checks.

Fix path: tighten SPF to approved vendors only. Add DKIM keys from your mail provider. Start DMARC at `p=none` if you are unsure about alignment errors, then move toward quarantine once reports are clean.

A minimal example looks like this:

v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com; adkim=s; aspf=s

4. Secrets exposure review

Signal: no API keys appear in Git history, frontend bundles, browser storage where they should not be publically readable by users.

Tool or method: I scan the repo history plus built assets for common key patterns. I also check deployment logs because founders often leak secrets there during debugging.

Fix path: rotate anything exposed immediately. Move secrets into server-side environment variables or managed secret stores. If a key was ever shipped to the client by mistake, assume it is compromised until proven otherwise.

5. Production deployment safety

Signal: deploys come from a controlled branch with a repeatable build process and rollback that works in practice.

Tool or method: I review CI/CD config, hosting settings, release history, and perform one test rollback if possible.

Fix path: lock production deploys to main or tagged releases only. Add a pre-deploy checklist for migrations so an automation-heavy product does not break webhooks or scheduled jobs mid-release.

6. Monitoring and alerting coverage

Signal: uptime monitoring covers homepage plus critical flows like login or booking; error tracking catches server failures; alerts route to real humans within minutes.

Tool or method: I verify synthetic checks from multiple regions plus application logs and incident notification paths.

Fix path: add one external uptime monitor for public pages and one internal error tracker for backend exceptions. Set alert thresholds so you get notified on repeated failures instead of noise from single blips.

Red Flags That Need a Senior Engineer

1. You have more than one place where deployment can happen. That usually means someone can ship unreviewed code straight to production.

2. Your app depends on third-party automations for login or payments but you cannot explain failure modes. If Stripe webhooks fail or email OTPs do not arrive then customers get stuck instantly. That becomes support load fast.

3. Secrets have been shared across frontend code, Zapier-style automations, serverless functions, and local env files. This is how leaks happen during fast launches because nobody knows which copy is current.

4. Cloudflare was turned on without testing auth flows. WAF rules can block legitimate mobile logins or webhook callbacks if configured too aggressively.

5. You cannot tell me what happens when production breaks at midnight. If there is no rollback plan plus no monitoring plus no owner then launch risk becomes business risk immediately.

DIY Fixes You Can Do Today

1. Audit your public DNS records. Remove duplicates for A, AAAA, CNAME, MX entries that point to old hosts. Keep a screenshot of the final zone so you know what changed later during incident review.

2. Check every public page on mobile with HTTPS forced. Open your homepage plus login plus booking flow on iPhone-sized viewport mode in Chrome DevTools. Fix any mixed content warnings before launch traffic arrives.

3. Rotate any secret you pasted into chat tools or shared docs. Assume anything copied into Slack screenshots or AI prompts may be compromised if it was sensitive enough to matter operationally.

4. Turn on basic monitoring now. Use one uptime check for the main URL and one alert channel that reaches you directly by SMS or email. A five-minute outage during launch can cost more than the service fee if ads are running.

5. Verify SPF/DKIM/DMARC with your email provider dashboard. If marketing emails work but transactional mail fails then your onboarding will leak users even though the site itself appears fine.

Where Cyprian Takes Over

If your checklist shows gaps anywhere below production-safe standards then I would take over the full launch hardening sprint rather than patching piecemeal fixes yourself while trying to market at the same time.

Here is how Launch Ready maps failures to deliverables:

| Failure found in audit | What I fix in Launch Ready | |---|---| | Domain points wrong way or has stale records | DNS cleanup for root domain plus subdomains | | SSL warnings or mixed content issues | Certificate setup plus HTTPS enforcement | | Broken redirects or canonical confusion | Redirect map cleanup plus routing validation | | Cloudflare blocks legit traffic | WAF tuning plus caching rules plus DDoS protection settings | | Email fails authentication checks | SPF/DKIM/DMARC setup verification | | Exposed secrets or unsafe env handling | Secret rotation guidance plus environment variable hardening | | Deployment is manual or risky | Production deployment configuration plus rollback notes | | No monitoring coverage | Uptime monitoring setup plus alert routing | | Handover is unclear after launch day | Delivery checklist documenting what lives where |

My delivery window is 48 hours because this kind of work should be handled as a focused sprint instead of an open-ended rebuild.

The practical outcome should be simple:

• Your domain resolves correctly.
• Your mobile-first app loads securely over HTTPS.
• Your emails land where they should.
• Your deploy process stops being scary.
• You know what breaks first if something goes wrong.

That is what "launch ready" means here: safe enough to accept real traffic without gambling with customer trust.
