Launch Ready cyber security Checklist for founder landing page: Ready for conversion lift in internal operations tools?.

What "ready" means for a founder landing page

For an internal operations tool, "launch ready" does not mean the page just looks good. It means the landing page can safely convert traffic without leaking data, breaking email trust, or creating support work for your team.

I would call it ready only if a founder can say: the domain resolves correctly, SSL is valid, redirects are clean, email authentication passes, no secrets are exposed, uptime is monitored, and the page loads fast enough to support conversion lift. For this type of product, my baseline is LCP under 2.5s on mobile, zero exposed secrets, SPF/DKIM/DMARC passing, and no critical auth or admin bypasses anywhere in the stack.

If any of those fail, conversion lift usually gets eaten by trust issues. Visitors bounce because the page feels unstable, email lands in spam, or a misconfigured deployment exposes internal tools data.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain ownership | Domain is registered under founder control and DNS access is documented | Prevents lockout and launch delays | You cannot update records or move providers | | SSL | HTTPS works on root and www with no mixed content | Trust and browser safety | Browser warnings kill conversions | | Redirects | One canonical path only, no loops or chains over 2 hops | Keeps SEO and tracking clean | Lost traffic and broken analytics | | Email auth | SPF, DKIM, DMARC all pass for outbound mail | Protects deliverability and brand trust | Emails go to spam or get spoofed | | Secrets handling | No API keys in repo, frontend bundle, or logs | Prevents data exposure and abuse | Leaked credentials and account takeover | | Cloudflare setup | DNS proxied correctly with WAF/DDoS protection on key routes | Reduces attack surface | Bot traffic and basic attacks hit origin | | Deployment safety | Production deploy uses environment variables and least privilege access | Stops accidental outages | A bad push breaks the live site | | Caching/performance | Static assets cached; LCP under 2.5s on mobile | Supports conversion lift | Slow load increases bounce rate | | Monitoring | Uptime alerts active for homepage and critical endpoints | Detects failures fast | Downtime goes unnoticed for hours | | Handover readiness | Founder has checklist for DNS, email, deploys, rollback, and contacts | Reduces support load after launch | Your team gets stuck on simple changes |

The Checks I Would Run First

1. Domain and DNS ownership

• Signal: The founder can prove registrar access and DNS admin access.
• Tool or method: Registrar dashboard review plus DNS record export.
• Fix path: Move domain control into the founder's account structure, document nameservers, then lock in A, CNAME, MX, TXT records before launch.

2. SSL and canonical routing

• Signal: `http://`, `https://`, `www`, and root all resolve predictably with one preferred version.
• Tool or method: Browser test plus `curl -I` checks for redirects.
• Fix path: Force one canonical domain at Cloudflare or the host. Remove redirect chains longer than 2 hops because they slow down users and create tracking noise.

3. Email authentication

• Signal: SPF passes, DKIM signs messages correctly, DMARC policy is at least `p=quarantine` once validated.
• Tool or method: MXToolbox or Google Postmaster checks plus test sends.
• Fix path: Publish correct TXT records and verify sending provider alignment. If this fails, your outbound sales emails and onboarding emails will lose trust.

4. Secrets exposure scan

• Signal: No keys in Git history, frontend bundles, environment files committed to repo, or console logs.
• Tool or method: Repo scan with GitHub secret scanning or TruffleHog.
• Fix path: Rotate anything exposed immediately. Move secrets to environment variables and server-side only access where possible.

5. Cloudflare edge protection

• Signal: The site is behind Cloudflare with SSL set to full strict where supported.
• Tool or method: Inspect DNS proxy status plus security headers from browser dev tools.
• Fix path: Enable WAF rules for obvious abuse patterns, rate limit login or form endpoints if they exist, and keep origin IP hidden where possible.

6. Monitoring and rollback

• Signal: Alerts fire when the site is down or returning errors.
• Tool or method: UptimeRobot or Better Stack monitoring plus a test outage drill.
• Fix path: Set homepage uptime checks at 1 minute intervals and add a rollback plan before every deploy. If you cannot restore within 10 minutes, you are not launch ready.

SPF: v=spf1 include:_spf.yourprovider.com ~all
DKIM: provider-managed signing enabled
DMARC: v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com

Red Flags That Need a Senior Engineer

1. You do not know who controls the domain registrar

• This creates real launch risk because a single lost login can block DNS changes for days.

2. Secrets have been pasted into frontend code or shared in chat

• This is not a cleanup task anymore. I would rotate keys first because exposed credentials can be abused immediately.

3. The site depends on multiple redirects across subdomains

• That usually means broken canonicalization, weak analytics accuracy, and avoidable load time loss.

4. Email deliverability already looks bad

• If onboarding emails are missing spam folders now, fixing it requires proper DNS alignment and sender reputation work.

5. The landing page touches internal ops data through forms or embedded tools

• Once a public page connects to internal systems, auth boundaries matter. A small mistake can expose customer data or create unauthorized access paths.

DIY Fixes You Can Do Today

1. Check your live domain paths

• Open the site on mobile using `http://`, `https://`, `www`, and non-`www`.
• Make sure each one lands on exactly one final URL.

2. Verify email authentication

• Send a test email to Gmail and Outlook.
• Confirm SPF pass, DKIM pass, DMARC pass in message headers.

3. Search for exposed secrets

• Scan your repo for `.env`, API keys, private URLs with tokens in them.
• If you find anything public-facing in GitHub history, rotate it today.

4. Turn on basic uptime monitoring

• Add checks for homepage availability every 1 minute.
• Alert by email plus Slack if possible so failures do not sit unnoticed overnight.

5. Reduce third-party script weight

• Remove any script you do not need for conversion tracking today.
• Every extra tag adds risk to performance and can break forms during outages.

Where Cyprian Takes Over

Here is how checklist failures map to the service deliverables:

| Failure area | Deliverable included in Launch Ready | Timeline | |---|---|---| | Domain confusion or broken DNS records | DNS setup plus subdomain cleanup | Hours 1-6 | | Bad redirects or mixed content warnings | Redirect fixes plus SSL validation | Hours 1-8 | | Email going to spam | SPF/DKIM/DMARC setup and verification | Hours 4-12 | | Exposed secrets or weak environment handling | Secrets cleanup plus production env vars review | Hours 6-18 | | Public origin exposure or bot abuse risk | Cloudflare config plus DDoS protection basics | Hours 8-20 | | Slow load from poor caching setup | Caching configuration plus asset review | Hours 10-24 | | Unclear deployment process / risky release flow | Production deployment hardening + handover checklist | Hours 18-36 | | No alerting if site breaks after launch | Uptime monitoring setup + alert routing | Hours 24-40 | | Founder needs confidence to operate it alone afterward | Handover checklist with exact steps and owners of each system touchpoint (DNS/email/deploy/monitoring) after delivery by hour 48 |

My rule is simple: if a failure can cause downtime, lost leads, spam-folder delivery problems, exposed customer data, or wasted ad spend inside the first week after launch then it belongs in this sprint instead of being patched later.
