Launch Ready cyber security Checklist for founder landing page: Ready for scaling past prototype traffic in founder-led ecommerce?.

What "ready" means for a founder-led ecommerce landing page

For this product, "ready" means your landing page can handle real buyer traffic without exposing customer data, breaking checkout handoffs, or collapsing under ads and email campaigns. It is not just "it loads on my laptop."

I would call it ready only if these are true:

• The domain resolves correctly with HTTPS on every key URL.
• Email authentication passes with SPF, DKIM, and DMARC so your order emails do not land in spam.
• No secrets are exposed in the frontend bundle, repo, or deployment logs.
• Cloudflare is in front of the site with basic DDoS protection and caching turned on.
• Redirects are clean, subdomains are intentional, and old URLs do not leak traffic or break trust.
• Monitoring is live so you know within minutes if uptime drops or SSL breaks.
• The page loads fast enough for paid traffic, with LCP under 2.5s on a decent mobile connection.
• There are no critical auth bypasses, broken forms, or weak admin endpoints that let strangers reach private data.

If you cannot say yes to all of that, you are still in prototype territory. That is fine for testing an idea. It is not fine when you start paying for traffic.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | HTTPS everywhere | All canonical URLs force SSL | Trust and browser security | Warning screens, lower conversions | | Domain DNS setup | A/AAAA/CNAME records resolve correctly | Visitors reach the right app | Downtime, wrong site loads | | Email auth | SPF, DKIM, DMARC all pass | Order and support email deliverability | Spam folder placement, lost sales | | Secrets handling | Zero secrets in client code or public repo | Prevents account takeover and abuse | API theft, billing fraud | | Cloudflare protection | Proxy on, WAF/DDoS baseline enabled | Shields against bot spikes and attacks | Outages during ad bursts | | Redirect hygiene | One canonical version per URL | Preserves SEO and user trust | Duplicate content, broken links | | Deployment safety | Production deploy is repeatable and reversible | Reduces launch risk | Broken release blocks sales | | Uptime monitoring | Alerts fire within 5 minutes of failure | Speeds incident response | You find outages from customers | | Cache strategy | Static assets cached correctly | Improves speed under load | Slow pages, higher bounce rate | | Handover docs | Clear checklist for DNS, env vars, rollback | Lets founder operate safely after launch | Support chaos and hidden dependencies |

The Checks I Would Run First

1. Domain and redirect integrity

Signal: `http://`, `https://`, `www`, non-www, and key subdomains all resolve to one intended destination.

Tool or method: I check DNS records, curl responses, browser behavior, and redirect chains. I want one clean path to the canonical landing page.

Fix path: Set one canonical domain, force HTTPS at the edge, remove redirect loops, and document every subdomain that exists for email, app, checkout, or admin use.

2. Email authentication health

Signal: SPF passes once per sending service, DKIM signs outbound mail correctly, and DMARC is at least in monitoring mode with aligned From headers.

Tool or method: I test with mail-tester tools and inspect DNS TXT records. I also send a real order-style email to confirm inbox placement.

Fix path: Publish correct SPF records only for approved senders, enable DKIM signing in your provider, then add DMARC with reporting first. If this fails now, your abandoned cart and order emails will be unreliable.

3. Secret exposure scan

Signal: No API keys, private tokens, webhook secrets, or service account credentials appear in frontend code or public Git history.

Tool or method: I scan the repo history plus deployed JS bundles. I also inspect environment variables in the hosting platform.

Fix path: Move every secret server-side or into platform-managed environment variables. Rotate anything already exposed. If a secret has ever been public, treat it as compromised.

4. Cloudflare edge protection

Signal: The site sits behind Cloudflare with SSL set correctly, caching enabled for static assets, and basic bot/DDoS controls active.

Tool or method: I inspect response headers like `cf-cache-status`, check TLS mode in Cloudflare settings, and confirm origin IP is not directly exposed where possible.

Fix path: Put the domain behind Cloudflare proxy mode on purpose. Lock down origin access where your host supports it. This matters when a campaign sends traffic spikes from 0 to 10k visits fast.

5. Production deployment repeatability

Signal: A fresh deploy from main produces the same working site every time without manual patching.

Tool or method: I run a clean deployment test from source control and verify build logs plus runtime behavior after release.

Fix path: Remove hidden manual steps. Use environment variables properly. Make rollback possible with one click or one command. If deployment depends on one person remembering tribal knowledge, it is not production-safe.

6. Monitoring and alerting coverage

Signal: Uptime checks hit the homepage plus any form endpoint every 1 to 5 minutes; alerts go to email and chat.

Tool or method: I set synthetic checks against the live URL and verify alert delivery by simulating downtime.

Fix path: Add uptime monitoring before launch day ends. Also monitor SSL expiry so you do not lose traffic because a certificate expired over a weekend.

SPF: v=spf1 include:_spf.your-email-provider.com -all
DMARC: v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com

Red Flags That Need a Senior Engineer

1. You have no idea where secrets live

If keys are scattered across code files, local `.env` files, hosting dashboards, and third-party automations without ownership rules, you need help now. This turns into leaked customer data or billing abuse very quickly.

2. Your landing page talks to multiple services through client-side calls

If the browser can directly hit payment APIs, CRM endpoints, webhook receivers, or admin routes using exposed tokens then your attack surface is too wide for DIY cleanup.

3. You already had one outage during a small traffic spike

One failed launch attempt is enough evidence that scaling past prototype traffic will hurt conversion if nothing changes. That usually means caching gaps, bad redirects,-slow third-party scripts,-or weak infrastructure defaults.

4. Email deliverability is already broken

If welcome emails or receipts are going to spam today with tiny volume then scaling will make it worse because mailbox providers punish low-quality authentication patterns hard.

5. You do not have rollback confidence

If deploying makes you nervous because there is no tested rollback path then every change becomes launch risk. That is how founders lose a weekend of sales over one bad release.

DIY Fixes You Can Do Today

1. Audit your live URLs

Open your homepage on mobile data plus desktop Wi-Fi. Check `http://` to `https://`, `www` to non-www or vice versa if needed by checking there is only one final destination after redirects.

2. Check email authentication

Use any reputable mail tester to verify SPF/DKIM/DMARC status before sending more campaigns. If DMARC does not exist yet then add it in monitor mode first instead of guessing later.

3. Rotate anything suspicious

If an API key was ever pasted into chat tools,,frontend code,,or screenshots then rotate it now.. Do not wait until launch week.. Exposure often happens by accident rather than attack..

4..Turn on uptime alerts

Add monitoring for homepage availability,,,SSL validity,,,and form submission success.. A simple alert within 5 minutes beats discovering failure from angry customers hours later..

5..Remove unnecessary third-party scripts

Kill any tracker,,chat widget,,or heatmap tool you do not actively use.. Every extra script adds latency,,privacy risk,,and another way for the page to fail under load..

Where Cyprian Takes Over

When DIY stops being safe,,this is exactly where Launch Ready fits..

Here is how failures map to the service:

• DNS mistakes -> I fix domain records,,subdomains,,and redirects.
• SSL issues -> I configure HTTPS properly end-to-end.
• Email deliverability problems -> I set up SPF,,DKIM,,and DMARC.
• Origin exposure / bot risk -> I place the site behind Cloudflare with caching and DDoS protection.
• Broken production deploys -> I ship the production deployment safely.
• Secret leakage risk -> I audit environment variables,,move secrets out of code,,and document what must be rotated.
• No visibility -> I add uptime monitoring so outages do not hide.
• No handover process -> I deliver a checklist so you know what changed,,what to watch,,and how to maintain it without guesswork..

My delivery window is tight on purpose.. In 48 hours,,you get setup work that removes launch blockers fast rather than a vague long-term roadmap..

Typical handoff looks like this:

1.. Audit current domain,,,,hosting,,,,email,,,,and secrets posture.. 2.. Fix critical DNS,,,,SSL,,,,redirect,,,,and Cloudflare issues.. 3.. Validate deployment,,,,monitoring,,,,and email auth.. 4.. Document what was changed plus what remains risky.. 5.. Hand over a production checklist you can use before spending more on ads..

If your page needs more than infrastructure cleanup - like UX redesign,,,copy tuning,,,or funnel fixes - I would separate that work into its own sprint so we do not mix security hardening with conversion experiments..
