Launch Ready cyber security Checklist for automation-heavy service business: Ready for handover to a small team in marketplace products?.

What "ready" means for Launch Ready

For an automation-heavy service business, "ready" means a small team can take over the product without breaking email, exposing secrets, or guessing how production works.

For this specific outcome, I would call it ready only if these are true:

• Domain and DNS are correct, with no broken redirects or stale records.
• Email authentication passes: SPF, DKIM, and DMARC all pass.
• SSL is valid everywhere, including subdomains and any marketplace-facing endpoints.
• Production deploys are repeatable, documented, and can be rolled back.
• Secrets are not in code, not in chat logs, and not in public repos.
• Cloudflare is configured to reduce risk, not block legitimate buyers or partners.
• Monitoring alerts the team before customers do.
• The handover pack explains who owns what, how to rotate secrets, and what to check after release.

If any one of those is missing, the business is not really ready. It may still "work," but it is fragile enough to create support load, failed onboarding, lost marketplace trust, or a security incident that stops sales.

Launch Ready is the kind of 48-hour sprint I would use when a founder has a working product and needs it production-safe fast. Delivery: 48 hours. The goal is not perfection. The goal is a clean handover to a small team with fewer ways to break things.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain ownership | Registrar access secured by 2FA and correct nameservers | Prevents hijack or accidental outage | Site can go offline or be redirected | | DNS records | A, CNAME, MX, TXT records match the live stack | Keeps web and email working | Broken site routes and failed email delivery | | SSL coverage | Valid certs on root domain and subdomains | Protects logins and trust signals | Browser warnings and blocked traffic | | SPF/DKIM/DMARC | All three pass on test sends | Improves deliverability and reduces spoofing | Emails land in spam or get rejected | | Cloudflare setup | WAF, caching, and DDoS protection enabled without blocking legit users | Reduces attack surface and load | Downtime during traffic spikes or attacks | | Secrets handling | Zero exposed secrets in repo, logs, CI output, or client code | Prevents account takeover and data leaks | Full compromise of APIs or databases | | Deployment process | One documented deploy path with rollback steps | Small teams need predictable releases | Broken launches and long recovery time | | Monitoring | Uptime checks plus error alerting to the right channel | Catches failures early | Support hears about outages first | | Redirects/subdomains | Canonical redirects work for main domain and key subdomains | Preserves SEO and user flow | Duplicate content, login issues, broken funnels | | Handover docs | Ownership list, credentials process, runbook, escalation path exist | Makes transfer usable by non-builders | Team cannot operate without the original founder |

The Checks I Would Run First

1. Domain control and DNS integrity

Signal: I look for registrar access locked behind 2FA, correct nameservers at the registrar level, and no orphaned records pointing at old hosts.

Tool or method: I check the registrar dashboard, run `dig` against the domain and subdomains, then compare live records with the intended architecture.

Fix path: If there are stale A records or old CNAME targets, I remove them carefully after confirming nothing still depends on them. If the domain is not protected with 2FA or transfer lock, I fix that first because a compromised registrar can take down the whole business.

2. Email authentication for marketplace trust

Signal: SPF passes once only one sending source is listed correctly. DKIM signs outbound mail. DMARC is present with at least `p=none` during initial validation or `p=quarantine` if the setup is mature.

Tool or method: I send test emails to Gmail and Outlook accounts and inspect headers. I also use MXToolbox-style checks to confirm alignment.

Fix path: I tighten SPF so it does not exceed DNS lookup limits. Then I publish DKIM keys from the actual provider used by the app. Finally I add DMARC reporting so spoofing attempts are visible instead of silent.

A simple example:

v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com; adkim=s; aspf=s

3. Secret exposure across code, CI, logs, and chat tools

Signal: Zero live API keys in source code, build output, browser bundles beyond public-safe keys like Stripe publishable keys only where expected.

Tool or method: I scan Git history, current branches, CI variables, deployment settings, browser source maps if exposed publicly, and recent logs.

Fix path: Any leaked secret gets rotated immediately. Then I move secrets into environment variables or a managed secret store. If a key ever hit a public repo or shared workspace file, I assume it is compromised even if nobody has reported abuse yet.

4. Cloudflare security posture

Signal: Cloudflare sits in front of the site with SSL enforced end to end where possible. WAF rules do not block normal checkout or signup flows.

Tool or method: I review DNS proxy status, SSL mode, firewall events, bot traffic patterns, page rules/redirect rules, and cache behavior on key pages.

Fix path: I enable HTTPS redirect at the edge only after confirming origin certificates are valid. Then I add basic WAF protection for obvious abuse paths like login forms and webhook endpoints. For marketplace products that depend on partner traffic sources or embedded flows, I keep an eye on false positives because overblocking kills conversions fast.

5. Deployment safety and rollback

Signal: A small team can deploy without editing production directly. There is one known path for release plus one known rollback path.

Tool or method: I inspect GitHub Actions, Vercel/Netlify/Render/Fly.io settings as relevant. Then I do a dry run from staging if staging exists.

Fix path: If deploys happen manually through dashboards with no traceability, I replace that with versioned deployments tied to git commits. If rollback does not exist in practice within 5 minutes max recovery time for common failures should be treated as unsafe until fixed.

6. Monitoring that actually wakes someone up

Signal: Uptime checks hit both homepage and critical transactional endpoints such as signup or webhook receivers. Alerts route to Slack/email/SMS owned by the team.

Tool or method: I verify synthetic checks from outside the platform regionally where possible. Then I trigger a controlled failure to confirm alerts arrive within minutes.

Fix path: If monitoring only watches homepage status code 200 but ignores auth failures or API errors near checkout/onboarding flow completion rate drops without warning. I add endpoint-level checks plus error tracking so support does not become the monitoring system.

Red Flags That Need a Senior Engineer

1. The founder cannot explain where secrets live today. That usually means secrets are scattered across chat tools, local files filesharing links files? No. It means there is no real control plane for access yet.

2. The app uses multiple email providers across onboarding flows. This creates deliverability drift where one message works and another lands in spam.

3. There are custom redirects for marketplace partners but nobody owns them. One bad rule can break acquisition campaigns overnight.

4. Production deploys require manual database edits. That is how you get partial releases that look fine until users hit edge cases later.

5. Cloudflare was turned on after launch without testing auth flows. Bot protection can block legitimate signups if it was configured by guesswork instead of observed traffic patterns.

DIY Fixes You Can Do Today

1. Turn on registrar 2FA now. This is cheap insurance against domain theft and accidental changes by former contractors.

2. Inventory every secret you know about. Make one list with owner name , location , purpose , last rotated date , then compare it against your repo history and deployment settings.

3. Send test emails from every user-facing address. Check inbox placement at Gmail plus Outlook , then confirm SPF/DKIM/DMARC alignment before you ship another campaign.

4. Verify your canonical domain flow. Pick one version of each URL format , then redirect all others consistently so users do not land on duplicate pages or broken subdomains.

5. Test your uptime page plus one critical action. Do not just ping home page . Test signup , login , form submit , webhook receive , or whichever step makes money .

Where Cyprian Takes Over

When these checks fail , Launch Ready becomes less about cleanup tasks and more about reducing business risk quickly .

Here is how I map failures to delivery:

| Failure found | What Launch Ready delivers | |---|---| | Domain/DNS confusion | DNS cleanup , redirects , subdomain mapping , registrar hardening | | Email deliverability issues | SPF/DKIM/DMARC setup , sender alignment , test validation | | SSL gaps | Certificate setup , HTTPS enforcement , mixed-content cleanup | | Secret exposure risk | Environment variable migration , secret rotation plan , access review | | Weak Cloudflare setup | WAF rules , caching rules , DDoS protection tuning | | Unsafe deployment process | Production deployment hardening , rollback notes , release checklist | | No monitoring / alerting | Uptime monitoring setup plus handover instructions | | Team cannot operate it alone | Handover checklist with ownership matrix and next-step actions |

The 48-hour timeline usually looks like this:

• Hours 0-8: audit domain , email , deploy surface , secrets .
• Hours 8-24 : fix high-risk items first .
• Hours 24-36 : validate SSL , Cloudflare rules , redirects .
• Hours 36-44 : set monitoring and test alerts .
• Hours 44-48 : handover checklist , ownership notes , final verification .

If you want this handed off cleanly to a small team running marketplace products , this is exactly why I'd recommend buying the service instead of trying to patch everything yourself under launch pressure .
