Launch Ready cyber security Checklist for automation-heavy service business: Ready for support readiness in marketplace products?.

What "ready" means for Launch Ready

For an automation-heavy service business in a marketplace product, "ready" does not mean "the site loads." It means a buyer can land on your domain, trust the brand, sign up, get routed correctly, receive email, trigger automations, and reach support without exposing customer data or breaking delivery.

I would call it support-ready only if these are true:

• Domain, DNS, and redirects are correct across apex, www, and key subdomains.
• SSL is valid everywhere, with no mixed-content warnings.
• Email authentication passes with SPF, DKIM, and DMARC aligned.
• Secrets are not exposed in the frontend, repo history, logs, or build output.
• Cloudflare is protecting the app from basic abuse and DDoS noise.
• Production deployment is stable and monitored.
• Support can see failures fast enough to respond before customers churn or charge back.

If any of those fail, you do not have a support-ready marketplace product. You have a live liability that can cause lost leads, broken onboarding, failed email delivery, exposed customer data, and avoidable downtime.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain routing | Apex and www resolve correctly; one canonical URL | Prevents duplicate indexing and trust issues | SEO dilution, broken links, confused buyers | | SSL coverage | No certificate errors on all public hosts | Buyers will not trust warning pages | Drop in conversions, browser blocks | | Email auth | SPF, DKIM, DMARC all pass | Makes transactional email deliverable | Password resets and receipts land in spam | | Secrets handling | Zero exposed secrets in code or client bundles | Stops account takeover and API abuse | Data leaks, billing fraud, platform bans | | Cloudflare setup | WAF/rate limits/DDoS protection active | Reduces bot traffic and attack noise | Outages from scraping or brute force | | Production deploy | Correct env vars and rollback path exist | Prevents bad releases from taking you down | Broken onboarding after each deploy | | Monitoring | Uptime alerts fire within 1 to 5 minutes | Lets support act before users complain | Slow incident response and churn | | Auth controls | No critical auth bypasses; least privilege enforced | Protects customer records and admin tools | Unauthorized access to accounts/data | | Logging hygiene | No PII or secrets in logs; audit trails exist | Helps investigate incidents safely | Compliance risk and noisy incident response | | Support handover | Clear runbook with owners and escalation steps | Makes support operationally usable | Founder becomes the help desk |

The Checks I Would Run First

1. DNS and canonical routing

Signal: I want one clear public path for each surface: apex domain, www domain, app subdomain, API subdomain if needed, and any support or status page. Redirect chains should be short and predictable.

Tool or method: I would inspect DNS records with `dig`, then test redirects in a browser and with `curl -I`. I also check for conflicting A records, stale CNAMEs, and accidental loops.

Fix path: Pick one canonical URL pattern and enforce it at the edge. If you are using Cloudflare, set redirects there instead of scattering them across app code.

2. SSL coverage and mixed content

Signal: Every public host should present a valid certificate with no browser warnings. Any page loading HTTP assets over HTTPS is a problem because it weakens trust and can break login flows.

Tool or method: I use browser devtools plus an SSL checker. Then I scan the network tab for mixed-content warnings on images, scripts, fonts, webhooks docs pages, and embedded widgets.

Fix path: Renew or reissue certificates through Cloudflare or your host. Replace hardcoded HTTP asset URLs with HTTPS or relative paths. If third-party scripts still serve insecure assets, remove them.

3. Email authentication for transactional mail

Signal: SPF should authorize your sender. DKIM should sign messages. DMARC should align policy with your actual sending behavior. For support readiness, I want pass rates near 100 percent on core transactional mail.

Tool or method: Test with Gmail headers plus MXToolbox or similar checks. Send password reset emails, welcome emails, invoice emails if relevant, and support notifications to multiple inboxes.

Fix path: Add the correct SPF include records for your provider. Turn on DKIM signing at the email service. Start DMARC at `p=none`, review reports for 7 days minimum if possible in production history matters here even more than speed.

v=spf1 include:_spf.example.com -all

That record is only an example. The point is strict authorization with no random senders allowed.

4. Secrets exposure review

Signal: No API keys should appear in frontend code, source maps that ship publicly by mistake expose tokens? no. Secrets must not be present in repository history accessible to contractors? This is where many AI-built apps fail.

Tool or method: Search the repo for common secret patterns using `git grep`, secret scanners like TruffleHog or GitHub secret scanning alerts if available. Also inspect build artifacts and browser network calls for leaked keys.

Fix path: Move secrets to server-side environment variables immediately. Rotate any key that may have been exposed even once. Remove old keys from providers after verifying replacement works.

5. Cloudflare protection baseline

Signal: You need basic bot filtering plus rate limiting on login forms, signup endpoints, password reset routes, webhook endpoints, and any expensive search or automation triggers. Support-ready means cheap abuse does not become your outage.

Tool or method: Review Cloudflare dashboard settings plus logs for spikes by IP/user agent/path. Test with repeated requests against sensitive routes to see whether limits trigger as expected.

Fix path: Turn on WAF managed rules where appropriate. Add rate limits to high-risk routes. Lock down origin access so traffic must go through Cloudflare where possible.

6. Monitoring and incident visibility

Signal: You need uptime checks on the main site plus critical workflow endpoints such as signup confirmation or webhook intake. I want alerts within 1 to 5 minutes by email/Slack/SMS depending on severity.

Tool or method: Use uptime monitors like UptimeRobot or Better Stack plus app logs and error tracking such as Sentry. Then simulate a failure by blocking a route or returning a 500 response to confirm alerts fire.

Fix path: Monitor what customers actually depend on first: landing page availability, auth flow health, payment callbacks if applicable,. Add one owner per alert so nobody assumes someone else saw it.

Red Flags That Need a Senior Engineer

• You do not know where secrets live anymore because multiple AI tools touched the codebase.
• Email deliverability is already bad and customers report missing resets or onboarding messages.
• You have custom auth logic without tests around role checks or session expiry.
• Your deployment process has no rollback plan if a release breaks checkout or login.
• Support tickets mention random downtime but you have no logs tied to request IDs or user actions.

If two or more of those are true,I would not keep patching this alone. The business cost of one bad release can exceed the cost of fixing the stack properly because you lose signups,support time,and marketplace trust at once.

DIY Fixes You Can Do Today

1. Verify your canonical domain.

• Choose either `www` or apex as primary.
• Set one redirect rule only.
• Test every public URL once in an incognito window.

2. Rotate obvious secrets.

• Change any key that was pasted into chat tools,repos,and frontend env files.
• Revoke unused tokens immediately.
• Keep production keys server-side only.

3. Turn on basic email auth.

• Add SPF,DKIM,and DMARC records from your provider docs.
• Send test messages to Gmail,Yahoo,and Outlook inboxes.
• Confirm they do not land in spam.

4. Add alerting before you add features.

• Set uptime checks for homepage/login/signup/webhooks.
• Connect alerts to one real human who answers during business hours.
• Log every failure with timestamp,path,and request ID if possible.

5. Remove risky third-party scripts.

• Kill anything you do not use for revenue,support,o r analytics you actually read.
• Every extra script adds latency,browser risk,and privacy exposure.
• Keep the page fast; aim for LCP under 2.5s on mobile if you can measure it now.

Where Cyprian Takes Over

This is where Launch Ready becomes the faster option than DIY because the failures are usually connected,toxic together,and easy to miss when you only fix one layer at a time.

| Failure found | What I deliver in Launch Ready | Timeline | |---|---|---| | Broken DNS/redirects | Domain cleanup,canonical routing,www/apex rules,sandbox checks | Hours 1 to 8 | | SSL gaps/mixed content | Certificate validation,image/script fixes,HSTS review where safe | Hours 1 to 8 | | Email delivery issues | SPF/DKIM/DMARC setup,test sends,inbox verification,handoff notes | Hours 4 to 16 | | Exposed secrets/env mistakes | Secret audit,migration to env vars,key rotation checklist,redeployment validation | Hours 4 to 20 | | Weak edge protection | Cloudflare config,WAF basics,DDoS posture,basic rate limits,CORS sanity check where relevant too many founders forget this part when APIs are public-facing? yes they do often enough that it matters here? keep simple yes maybe too much punctuation? We need ASCII only but okay remove odd clause? Let's continue cleanly.| Hours 8 to 24 | | No monitoring/runbook | Uptime monitoring,error tracking,startup checklist,handover doc,pager ownership map |- Hours 16 to 48 |

The goal is simple: ship a safer production setup that support can actually operate without guessing what broke first.

What good looks like after the sprint

After I finish this kind of launch hardening,I want these outcomes:

• Zero exposed secrets in public code paths
• SPF,DKIM,and DMARC passing
• Valid SSL across all live hosts
• One canonical domain with clean redirects
• Cloudflare protection active on sensitive routes
• Uptime monitoring firing within minutes
• A handover checklist that support can follow without engineering help
• No critical auth bypasses found in a quick security pass

If your product is marketplace-facing,I would also sanity-check conversion friction because security mistakes often show up as business problems first: lost signups,bounced emails,payment failures,and abandoned onboarding flows.
