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

What "ready" means for Launch Ready

For this product, "ready" means a mobile-first app can take real production traffic without exposing customer data, breaking email deliverability, or falling over under normal launch load.

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

• The domain resolves correctly for the app, API, and any subdomains.
• HTTPS is enforced everywhere, with valid SSL and no mixed content.
• Email authentication is passing: SPF, DKIM, and DMARC are set and verified.
• Secrets are not in the repo, not in client-side code, and not in shared docs.
• Cloudflare or equivalent edge protection is active for caching and DDoS defense.
• The deployment path is repeatable and rollback is known.
• Uptime monitoring is live with alerts going to a real human.
• Mobile users can load the app with LCP under 2.5s on a typical 4G connection.
• Auth has no obvious bypasses, role leaks, or broken access control.
• The handover includes who owns DNS, hosting, email, secrets, alerts, and rollback.

If even one of those is missing, you do not have a launch-ready system. You have a demo that can fail publicly, create support load, waste ad spend, or leak customer data.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | DNS ownership | Root domain and key subdomains resolve to the correct targets | Traffic must reach the right app and APIs | Users hit stale pages, wrong environment, or dead links | | HTTPS enforced | All routes redirect to TLS with no mixed content | Protects login sessions and forms | Browser warnings, session theft risk, lower trust | | SPF/DKIM/DMARC | All three pass for sending domain | Keeps transactional email out of spam | Magic links, receipts, and alerts stop arriving | | Secrets handling | Zero secrets in frontend bundles or public repos | Prevents credential theft | Account takeover, cloud abuse, data exposure | | Authz review | No critical auth bypasses or IDOR paths found | Stops users seeing other users' data | Privacy breach and legal risk | | Cloudflare config | WAF/CDN/DDoS protection enabled with sane rules | Shields launch traffic spikes and attacks | Downtime from bot traffic or simple floods | | Deployment safety | Production deploy is repeatable and rollback works in under 10 minutes | Limits blast radius of bad releases | Broken app stays live too long | | Monitoring | Uptime checks plus error alerts are active | Finds failures before customers do | Silent outages and missed revenue | | Mobile performance | LCP under 2.5s and CLS under 0.1 on key pages | Mobile users convert only if pages feel fast | Higher bounce rate and ad waste | | Logging hygiene | Logs exclude tokens, passwords, PII where possible | Prevents leaks through observability tools | Sensitive data ends up in third-party systems |

The Checks I Would Run First

1. Domain and DNS routing

Signal: The apex domain, www subdomain, app subdomain, API subdomain, and email records all point to the intended targets with no orphaned records.

Tool or method: I check registrar settings, DNS records, Cloudflare zone config if used as proxy, and I verify propagation from multiple locations. I also test old URLs to confirm redirects are correct.

Fix path: Clean up conflicting A/CNAME records first. Then set canonical redirects so there is one public version of the site. If staging is exposed by mistake, I remove public access or lock it behind auth.

2. TLS enforcement and mixed content

Signal: Every page loads over HTTPS only. There are no insecure scripts, images, fonts, or API calls that trigger browser warnings.

Tool or method: I use browser dev tools plus an automated crawl for mixed content. I also inspect certificate validity and renewal ownership so nobody gets surprised by expiry.

Fix path: Force HTTPS at the edge. Update hardcoded http links in templates, emails, metadata files, and frontend env vars. If a third-party asset cannot serve TLS reliably, replace it.

3. Email authentication for transactional reliability

Signal: SPF passes for your sender domain. DKIM signs mail correctly. DMARC is at least set to p=none during validation and moved toward quarantine/reject once stable.

Tool or method: I send test messages through the actual provider and inspect headers with a mail tester plus DNS lookups. I verify bounce handling too.

Fix path: Add the exact provider include records recommended by your email platform. Keep one source of truth for sending domains. If magic links or receipts matter to revenue support load stays low only when mail lands reliably.

A simple example:

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

4. Secrets exposure review

Signal: No API keys appear in Git history accessible branches build logs client bundles crash reports or shared docs.

Tool or method: I scan the repo history current codebase CI logs deployed assets and environment files. I also search for common patterns like private keys JWT signing secrets service tokens webhook secrets and database URLs.

Fix path: Rotate anything exposed immediately. Move runtime-only values into server-side env vars or secret managers. Never ship admin credentials to mobile apps because anything in the client must be treated as public.

5. Auth boundaries and object-level access control

Signal: A user cannot read update delete or export another user's resources by changing IDs roles headers or query params.

Tool or method: I test role switching direct object references forced browsing token reuse expired token behavior and unauthorized API calls from mobile clients.

Fix path: Enforce authorization on every sensitive endpoint not just in UI guards. Use server-side policy checks on resource ownership tenant scope and role claims. This is where many AI-built apps fail because the screens look right but the backend trusts too much.

6. Edge protection plus observability

Signal: Cloudflare or equivalent has caching rules WAF basics bot mitigation rate limiting where needed plus uptime monitoring alerting on both availability and error spikes.

Tool or method: I review dashboard settings synthetic checks response codes log samples alert destinations incident routing and cache hit ratio on static assets.

Fix path: Cache static assets aggressively but never cache private user data unless you have explicit safe rules. Add alerts for downtime 5xx spikes auth failures checkout failures webhook failures and elevated latency above p95 500ms on critical APIs.

Red Flags That Need a Senior Engineer

1. You have multiple environments but no clear production boundary. That usually means test data can leak into live systems or live traffic can hit staging by accident.

2. Secrets were copied into Lovable Bolt Cursor screenshots shared docs or frontend env files. Once that happens you need rotation plus a proper secret handling plan not just cleanup.

3. The app depends on third-party automations with admin scopes. One bad integration can expose customer records send emails as your brand or trigger destructive actions.

4. You cannot explain who owns DNS hosting email alerts backups and rollback. If ownership is unclear then recovery will be slow when something breaks at launch time.

5. Your mobile app ships slowly already. If LCP is above 2.5s on mid-range phones before launch then paid traffic will amplify the problem immediately.

DIY Fixes You Can Do Today

1. Confirm your public domains Make a list of every URL customers might use including old marketing links login links API endpoints help docs and subdomains.

2. Rotate any exposed secrets If you pasted keys into chat tools repo files screenshots or client code rotate them now before you do anything else.

3. Turn on Cloudflare basic protection Put the site behind Cloudflare enable SSL set always use HTTPS add sensible caching rules for static assets only then test login flows again.

4. Set SPF DKIM DMARC Use your email provider's exact setup instructions then send a test message to Gmail Outlook and Apple Mail to confirm delivery headers pass cleanly.

5. Run one mobile smoke test Open the app on an actual phone over cellular data sign in create one record trigger one automation log out log back in then check whether any step feels slow confusing or broken.

Where Cyprian Takes Over

If you hit any of these failures Launch Ready becomes the faster cheaper option than trying to patch things piecemeal:

| Failure found | What I fix in Launch Ready | Time window | |---|---|---| | DNS confusion or wrong redirects | Domain mapping redirects subdomains canonical URLs | Hours 1-6 | | SSL issues mixed content insecure forms | TLS enforcement Cloudflare edge cleanup asset fixes | Hours 1-8 | | Email deliverability problems | SPF DKIM DMARC sender setup validation tests handoff notes | Hours 4-12 | | Secret exposure risk | Environment variable cleanup secret rotation deployment hardening | Hours 2-18 | | Broken deployment process | Production deploy rollback checklist release verification steps | Hours 8-24 | | No monitoring visibility | Uptime monitors alert routing error tracking baseline checks | Hours 12-24 | | Mobile performance regressions after launch prep | Caching optimization asset cleanup third-party script review performance checks | Hours 18-36 | | Unclear handover ownership | Final checklist credentials map runbook support boundaries signoff packageremove? |

My recommendation is simple: if more than two items in the scorecard fail buy the sprint instead of DIYing it across weekends.

Launch Ready is built for this exact gap:

48 hour delivery, and coverage of DNS redirects subdomains Cloudflare SSL caching DDoS protection SPF DKIM DMARC production deployment environment variables secrets uptime monitoring plus handover checklist.

For an automation-heavy service business serving mobile-first users that combination matters because small misconfigurations become expensive fast: broken onboarding hurts conversion, bad mail setup kills activation, and weak security creates legal risk before you have product-market fit.
