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

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

Ready means a stranger can click your ad, land on the page, trust the domain, load the page fast, complete checkout or lead capture, and never hit a security or deliverability failure. If any part of that chain is weak, you are not ready for paid traffic, because every broken session turns into wasted ad spend, support tickets, and lost revenue.

For founder-led ecommerce, I would define "ready" as this: zero exposed secrets, HTTPS everywhere, SPF/DKIM/DMARC passing, redirects working cleanly, Cloudflare protecting the edge, monitoring alerting within 5 minutes of downtime, and no critical auth or checkout bypasses. On performance, I want LCP under 2.5s on mobile for the landing page and p95 API responses under 500ms for the conversion path.

If you cannot answer "yes" to most of the checklist below, you are not ready to scale spend. You may still have a product that works in demo mode, but paid acquisition punishes weak infrastructure fast.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | HTTPS everywhere | All pages and assets load over HTTPS with no mixed content | Trust and browser security | Browser warnings, blocked assets, lower conversion | | DNS correctness | Domain resolves to the right app with clean apex and www behavior | Ad clicks must land correctly | Dead links, duplicate indexing, broken tracking | | Redirects | 301 redirects are intentional and tested | Preserves SEO and ad destination integrity | Looping redirects, lost traffic, failed landing pages | | Cloudflare setup | WAF/CDN/DDoS protection enabled with sane rules | Reduces bot abuse and downtime risk | Origin overload, scraping, attack exposure | | Email auth | SPF, DKIM, and DMARC all pass | Keeps receipts and abandoned cart emails out of spam | Lost order emails, poor deliverability | | Secrets handling | No secrets in code or client-side bundles | Prevents account takeover and data leaks | Payment compromise, admin compromise | | Deployment safety | Production deploy is repeatable and rollback exists | Paid traffic amplifies release mistakes | Broken funnel after launch | | Monitoring | Uptime alerts configured with 5 minute notification target | You need fast detection when ads are live | Hours of silent downtime | | Caching/performance | Core pages load fast with caching tuned | Faster pages convert better under paid traffic | High bounce rate and wasted CPC | | Access control | Least privilege for admins and vendors | Limits blast radius if an account is compromised | Full store takeover or data exposure |

The Checks I Would Run First

1) DNS points exactly where it should

Signal: The apex domain and www version resolve to the correct production app with one intentional redirect path. No stale A records, no surprise CNAME chains.

Tool or method: I would check DNS records in your registrar and test resolution from multiple regions using `dig`, `nslookup`, or an online DNS checker. Then I would click every ad destination URL with tracking parameters to confirm there is no redirect loop.

Fix path: Remove old records, standardize on one canonical domain pattern, then set 301 redirects from non-canonical variants. If you use subdomains like shop., checkout., or app., I would document each one so ads never point at a dead endpoint.

2) SSL is valid across every customer-facing route

Signal: No certificate errors in browser tests. No mixed content warnings from scripts, images, fonts, or embedded widgets.

Tool or method: I would test in Chrome DevTools and run a site scan for mixed content. I also check certificate expiry dates so you do not get surprised during a campaign week.

Fix path: Force HTTPS at the edge with Cloudflare or your host. Replace any hardcoded http:// asset URLs in templates, theme files, email templates links where relevant.

3) Email authentication passes before you send receipts or abandoned cart flows

Signal: SPF passes for your sending provider. DKIM signs messages correctly. DMARC is present with at least p=none while testing and then tightened once stable.

Tool or method: I would use MXToolbox or Google Postmaster Tools plus a live inbox test from Gmail and Outlook. If your receipts go to spam now, paid traffic will amplify that failure immediately.

Fix path: Add the exact SPF include from your email platform only once. Publish DKIM keys. Add a DMARC record and monitor reports before enforcing stricter policy.

A minimal example looks like this:

v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com; fo=1

4) Secrets are not exposed in code or frontend bundles

Signal: No API keys in Git history, client-side JS bundles, public repo files, build logs, or environment screenshots. Zero exposed secrets is the target.

Tool or method: I would search the repo with secret scanners like GitGuardian-style tools or `gitleaks`, then inspect built assets in the browser network tab. I also review deployment logs because founders often leak keys there by accident.

Fix path: Rotate anything exposed immediately. Move sensitive values into server-side environment variables or managed secret storage. Remove old keys from history if needed.

5) Checkout and tracking work under real traffic conditions

Signal: Add-to-cart flow works on mobile Safari and Chrome. Payment handoff succeeds. Analytics events fire once only. UTMs survive redirects.

Tool or method: I would run end-to-end tests plus manual tests on iPhone-sized viewports. Then I verify network requests during checkout to catch double fires or missing events that ruin attribution.

Fix path: Fix event duplication first because it distorts ad reporting. Then validate payment webhooks and thank-you page routing so orders do not disappear after successful payment.

6) Monitoring tells you about outages before customers do

Signal: Uptime checks hit key URLs every minute or every 5 minutes. Alerts go to email and Slack immediately when status changes. Error logging captures deploy failures.

Tool or method: I would inspect your monitoring dashboard plus one synthetic check against homepage and checkout endpoints. For ecommerce funnels I also want alerting on payment failures if webhooks are involved.

Fix path: Set up uptime monitoring for homepage, product page, checkout page, and webhook endpoint if applicable. Add rollback instructions so you can revert quickly without waiting on a developer call.

Red Flags That Need a Senior Engineer

1) You have no idea where your DNS is managed.

• That usually means nobody owns production risk.
• One wrong edit can take the whole funnel offline during spend hours.

2) Your domain sends email but SPF/DKIM/DMARC were never verified.

• Receipts can land in spam.
• Abandoned cart recovery becomes unreliable right when you need it most.

3) Secrets were copied into `.env`, shared in Slack screenshots, or pasted into frontend code.

• This is how stores get compromised.
• A leaked admin token is more expensive than a proper fix sprint.

4) The site works on your laptop but fails on mobile Safari.

• Paid acquisition traffic is often majority mobile.
• If mobile checkout breaks even at 10 percent of sessions, CAC rises fast.

5) You cannot roll back a bad deploy within 10 minutes.

• Every campaign launch becomes risky.
• A single broken release can waste an entire day of ad spend before anyone notices.

DIY Fixes You Can Do Today

1) Turn on Cloudflare proxying for public web traffic.

• Use it as the front door for DNS protection plus basic DDoS shielding.
• Do not change origin settings blindly if you are unsure what your host expects.

2) Check every important URL with HTTPS only.

• Homepage.
• Product page.
• Cart.
• Checkout.
• Thank-you page.

If any route still loads over HTTP first, fix that now.

3) Verify SPF/DKIM/DMARC with your email provider.

• Most providers show copy-paste records in their setup docs.
• Wait until all three pass before scaling campaigns that rely on email follow-up.

4) Rotate any key that has been shared outside secure secret storage.

• If it was pasted into chat once, assume it is compromised.
• Create new keys first, then revoke old ones after confirming production still works.

5) Set up basic uptime alerts today.

• Use UptimeRobot or similar tools for homepage and checkout URLs.
• Set alerts to email plus Slack so failures do not sit unnoticed overnight.

Where Cyprian Takes Over

If these checks feel messy or partially broken across different tools people touched over time setup drift usually costs more than founders expect. That is where Launch Ready fits: I clean up the production surface area fast so paid acquisition does not start on top of hidden risk.

Here is how I map failures to deliverables:

• DNS confusion
• Deliverable: DNS cleanup, canonical domain setup, subdomain mapping
• Timeline: first few hours
• Outcome: clean routing for ads and customers

• SSL errors or mixed content
• Deliverable: SSL enforcement plus asset cleanup
• Timeline: same day
• Outcome: no browser trust warnings

• Weak edge protection
• Deliverable: Cloudflare setup including caching rules and DDoS protection
• Timeline: same day
• Outcome: lower attack surface and faster load times

• Email deliverability problems
• Deliverable: SPF/DKIM/DMARC configuration
• Timeline: within the 48 hour sprint
• Outcome: receipts and lifecycle emails reach inboxes more reliably

• Secret leaks or unsafe env handling
• Deliverable: environment variable audit plus secret cleanup
• Timeline: within the sprint window
• Outcome: zero exposed secrets in production-facing surfaces

• No monitoring
• Deliverable: uptime monitoring setup plus handover checklist
• Timeline: final stage of the sprint
• Outcome: you know about failures before ad spend compounds them

• Domain setup
• Email authentication
• Cloudflare configuration
• SSL enforcement
• Redirects and subdomains
• Production deployment review
• Secrets review
• Uptime monitoring
• Handover checklist

My recommendation is simple: if you are planning paid acquisition this week and any item above is uncertain, buy the sprint instead of improvising around launch risk. The cost of one bad day of ads often exceeds the fix cost by a wide margin.
