Launch Ready cyber security Checklist for founder landing page: Ready for paid acquisition in founder-led ecommerce?.

What "ready" means for founder-led ecommerce paid acquisition

For a founder-led ecommerce landing page, "ready" means I can send paid traffic to it without creating avoidable business risk. The page should load fast, collect leads or purchases reliably, protect customer data, and not fall apart when ad spend starts hitting it.

If I were self-assessing, I would want these basics true before launch: LCP under 2.5s on mobile, no exposed secrets in the repo or browser, SSL valid everywhere, SPF/DKIM/DMARC passing, redirects clean, Cloudflare protecting the edge, and uptime monitoring alerting me before customers do. If any of those are missing, you are not ready for paid acquisition because every click becomes more expensive than it should be.

Launch Ready is the service I would use when the product is close but the security and deployment layer is not production-safe yet.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain setup | Root domain and www resolve correctly with one canonical version | Avoids duplicate content and broken ad landing URLs | SEO confusion, tracking splits, user trust loss | | SSL everywhere | HTTPS valid on all pages and subdomains | Protects form data and checkout trust | Browser warnings, lower conversion | | Redirects | 301 redirects are consistent and tested | Keeps paid traffic on the right path | Broken campaigns, lost attribution | | Email auth | SPF, DKIM, DMARC all pass | Prevents spoofing and improves deliverability | Emails hit spam or get blocked | | Secrets handling | No API keys in client code or repo history | Stops data leaks and abuse | Exposed accounts, surprise bills | | Cloudflare config | WAF/DDoS/basic bot protection enabled | Reduces noise and attack surface | Spam floods, downtime | | Deployment safety | Production deploy uses environment variables only | Keeps configs separated from code | Leaked credentials or broken releases | | Monitoring | Uptime checks and alerts active within 5 minutes of failure | Detects outages fast enough to save spend | Paid traffic goes to dead pages | | Caching/performance | Mobile LCP under 2.5s on key page paths | Paid traffic converts better when pages are fast | Higher bounce rate and wasted ad spend | | Handover readiness | Clear checklist for DNS, email, rollback, owner access | Makes future changes safer and faster | Founder gets locked out or breaks setup |

The Checks I Would Run First

1. Domain and redirect chain check

Signal: One clean canonical URL for the landing page. No redirect loops, no mixed http/https behavior, and no accidental split between root domain and www.

Tool or method: I would test with browser dev tools plus `curl -I` against root, www, campaign URLs, and subdomains. I also check whether analytics tags fire after redirects.

Fix path: Set a single canonical host, then add one 301 redirect from every alternate version to that host. If the site uses multiple environments or marketing subdomains, I map them before launch so paid ads never point at a stale URL.

2. SSL and mixed content audit

Signal: The lock icon is not enough. All scripts, images, fonts, forms, pixels, and embedded widgets must load over HTTPS with no mixed-content warnings.

Tool or method: I use Chrome DevTools Console plus a crawler like Screaming Frog or Sitebulb to catch insecure assets. I also inspect third-party scripts because those often break first.

Fix path: Replace all http asset links with https versions or self-host them if needed. If a vendor does not support HTTPS cleanly, I remove it before launch because one insecure widget can damage trust across the whole page.

3. Secrets exposure check

Signal: No API keys visible in frontend bundles, environment files committed to Git history, or public deployment logs.

Tool or method: I scan the repo with `git grep`, secret scanners like Gitleaks or TruffleHog, and browser source inspection. I also check CI logs because founders often leak keys there by accident.

Fix path: Move every secret into environment variables on the hosting platform. Rotate anything that may have been exposed already. If a key cannot be safely scoped down to least privilege, I replace it before any ad spend goes live.

A simple example of what "good" looks like:

## Example environment variables only
NEXT_PUBLIC_SITE_URL=https://example.com
STRIPE_SECRET_KEY=sk_live_...
RESEND_API_KEY=re_...

4. Email authentication check

Signal: SPF passes for your sender domain; DKIM signs outgoing mail; DMARC is present with at least `p=none` during setup and then tightened later.

Tool or method: I verify DNS records directly and test with a real email sent to Gmail plus a deliverability checker. For founder-led ecommerce this matters because abandoned cart emails and order confirmations need to land.

Fix path: Publish correct TXT records in DNS through Cloudflare or your registrar. Then confirm alignment between sending domain and From address so transactional mail does not look spoofed.

5. Cloudflare edge protection review

Signal: DNS is proxied where appropriate; DDoS protection is active; basic WAF rules exist; admin paths are not publicly noisy; caching behavior is intentional.

Tool or method: I inspect Cloudflare settings directly plus request headers from live traffic. I also test whether origin IPs are exposed anywhere public.

Fix path: Put the site behind Cloudflare proxy where possible. Lock down origin access so attackers cannot bypass the edge easily. If you have admin panels or preview builds on public domains without protection, move them behind auth or off public DNS entirely.

6. Monitoring and rollback readiness

Signal: Uptime monitoring exists before launch day. There is an owner for alerts, a rollback path for bad deploys exists in writing, and basic error logging is visible somewhere central.

Tool or method: I simulate an outage by checking whether alerts arrive within 5 minutes through email or Slack. Then I verify that logs show enough detail to diagnose failures without exposing customer data.

Fix path: Add uptime checks on homepage plus key conversion endpoints like checkout or form submit success pages. Keep rollback instructions short enough that a non-technical founder can follow them under pressure.

Red Flags That Need a Senior Engineer

1. You have Stripe connected but no clear way to stop duplicate charges if retries happen. 2. Your landing page includes third-party scripts from half a dozen vendors you do not fully understand. 3. The site works locally but production deploys fail randomly because env vars differ across environments. 4. You see secrets in browser source code but are unsure whether they were already copied. 5. Paid traffic will go live before you have alerts for downtime or failed forms.

If any of those are true, DIY becomes expensive quickly. The real cost is not just security risk; it is wasted ad spend while conversion tracking breaks silently.

DIY Fixes You Can Do Today

1. Check your live URL behavior

• Open root domain, www version, mobile viewports.
• Confirm they all land on one canonical URL.
• Fix obvious redirect chains before doing anything else.

2. Review browser console errors

• Load the page in Chrome.
• Look for mixed content warnings, blocked scripts, CORS errors.
• Remove broken third-party embeds if they are not essential.

3. Rotate any obvious secrets

• Search your repo for API keys.
• Move them into platform environment variables.
• Rotate anything that has ever been committed publicly.

4. Publish email DNS records

• Add SPF first.
• Add DKIM from your email provider.
• Add DMARC so spoofing gets reported instead of ignored.

5. Set up basic uptime alerts

• Use UptimeRobot or similar on homepage plus checkout/form endpoint.
• Alert by email immediately.
• Make sure someone actually receives the alert before launch day.
