Launch Ready cyber security Checklist for paid acquisition funnel: Ready for handover to a small team in bootstrapped SaaS?.

What "ready" means for a paid acquisition funnel

For a bootstrapped SaaS, "launch ready" does not mean the site looks finished. It means paid traffic can land, convert, and hand off to a small team without exposing customer data, breaking email delivery, or creating a support mess.

I would call this ready only if the funnel can survive real ad spend with no critical auth bypasses, zero exposed secrets, SPF/DKIM/DMARC all passing, SSL forced everywhere, and basic monitoring in place. If a founder can say "we can pause ads, fix an issue, and know within minutes if something breaks", then the setup is close.

For this specific outcome, the bar is simple:

• Domain and DNS are correct.
• Email is authenticated and deliverable.
• Cloudflare is protecting origin traffic.
• Production deployment is repeatable.
• Secrets are not in code or client-side bundles.
• Monitoring catches downtime before customers do.
• A small team can take over without tribal knowledge.

If any one of those is missing, paid acquisition becomes expensive damage control. You waste ad spend, lose leads, trigger app review or deliverability issues, and create avoidable downtime.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | DNS | Root domain and subdomains resolve correctly; no stale records | Traffic must reach the right app and email providers | Landing pages fail, emails bounce, old apps stay live | | SSL | HTTPS forced on all entry points; no mixed content | Trust and browser security depend on it | Warning screens, lower conversion, broken forms | | Cloudflare | Proxy enabled where needed; WAF and DDoS protection active | Protects origin and absorbs junk traffic | Origin gets attacked directly | | Email auth | SPF, DKIM, DMARC pass | Paid funnels rely on lead and receipt delivery | Sales emails land in spam or get rejected | | Redirects | 301 redirects map old URLs to new ones cleanly | Preserves SEO and ad campaign continuity | Broken ads, lost attribution, duplicate pages | | Secrets handling | Zero secrets in repo or frontend bundle | Prevents account takeover and data leaks | API abuse, leaked keys, cloud bills spike | | Deployment | Production deploy is repeatable from source control | Small teams need safe handover | Manual releases cause outages | | Monitoring | Uptime checks + alerting active for key endpoints | You need fast detection during ad spend windows | Downtime goes unnoticed for hours | | Access control | Least privilege on domain, hosting, analytics, email tools | Limits blast radius for mistakes or compromise | One stolen login can wreck everything | | Logging/backup trail | Basic logs and rollback path exist; config changes tracked | Recovery needs evidence and reversibility | No way to diagnose failure quickly |

The Checks I Would Run First

1. Domain ownership and DNS hygiene

Signal: The apex domain resolves to the intended landing page, `www` redirects once only, subdomains are intentional, and there are no orphaned A records pointing at old hosts.

Tool or method: I check the registrar panel, Cloudflare DNS zone file, `dig`, browser tests from incognito mode, and historical DNS records if available.

Fix path: Remove stale records first. Then set canonical redirects so one public URL wins for each page. For paid funnels I prefer one primary domain per offer because split authority creates tracking noise.

2. Email authentication and deliverability

Signal: SPF includes only approved senders, DKIM signatures validate for every sending domain, and DMARC is set to at least `p=quarantine` after testing. You want pass rates near 100 percent before traffic scales.

Tool or method: I use MXToolbox-style checks plus actual test sends to Gmail and Outlook. I also inspect header results to confirm alignment rather than trusting provider dashboards.

Fix path: Publish one SPF record only. Enable DKIM at the sender. Add DMARC reporting so failures are visible. If you send transactional mail from a separate service than marketing mail, split them cleanly by subdomain.

3. Secret exposure audit

Signal: No API keys in Git history that still work today; no `.env` values bundled into frontend JavaScript; no service credentials in screenshots or docs.

Tool or method: I scan the repo history with secret detection tools and then verify runtime environment variables in the deployment platform. I also inspect built assets because many founders miss secrets that were compiled into client code.

Fix path: Rotate anything exposed immediately. Move secrets into server-side environment variables or managed secret storage. If a key has already been committed publicly once, assume it is burned.

4. Cloudflare edge protection

Signal: Cloudflare proxy is on for public web traffic where appropriate; WAF rules block obvious abuse; rate limiting protects forms; origin IP is not publicly advertised unless required.

Tool or method: I test direct-origin access from outside Cloudflare paths and inspect response headers. I also simulate form abuse with repeated requests to see whether rate limits actually trigger.

Fix path: Put the app behind Cloudflare with SSL set to full strict. Lock down origin firewall rules to Cloudflare IP ranges only if your host supports it. Add bot filtering carefully so you do not break legitimate conversions.

5. Production deploy safety

Signal: A new release can be deployed from source control with one documented path and rolled back without guesswork. Build logs show success consistently across environments.

Tool or method: I run a dry deploy from staging or preview into production-like settings. Then I compare environment variables across environments so there is no hidden config drift.

Fix path: Make deployment boring. Use one pipeline per environment with explicit approvals if needed. If manual steps still exist in chat messages or someone's memory, handover is not ready yet.

6. Monitoring on revenue-critical paths

Signal: Uptime monitoring watches homepage load, signup form submit success, checkout or lead capture endpoint health if present, and email sending status where possible.

Tool or method: I set synthetic checks against the exact funnel pages users hit from ads. Then I confirm alerts go to more than one person so a single missed notification does not hide an outage.

Fix path: Start with simple uptime alerts plus error logging on forms and auth flows. For bootstrapped teams I prefer fewer monitors that actually get read over dashboards nobody opens.

Red Flags That Need a Senior Engineer

1. The app works only because someone manually patched production last week

That usually means hidden state lives outside source control. Small teams cannot safely inherit that setup because every change risks breaking billing or lead capture.

2. Secrets have been shared through Slack screenshots or pasted into docs

This is not just messy; it is an active breach risk. Once credentials spread across chat exports and personal devices, rotation becomes urgent work instead of routine cleanup.

3. Email sends from multiple domains with inconsistent authentication

This causes spam placement problems that paid acquisition magnifies fast. If leads do not receive confirmations within minutes, conversion drops even when ads are working.

4. Cloudflare exists but origin access is still public

That means the security layer is cosmetic rather than protective. A direct hit on the host can bypass WAF rules entirely unless origin access is locked down properly.

5. Nobody knows how to roll back a bad deploy in under 10 minutes

For a funnel running paid traffic this is unacceptable. Every extra minute of broken checkout or broken form submission burns budget and damages trust.

DIY Fixes You Can Do Today

1. List every public domain and subdomain

Write down what should exist now versus what was used during development. Remove anything old that still resolves but should not be public anymore.

2. Check your email authentication

Use your provider's DNS instructions and verify SPF includes only approved services. Make sure DKIM signing is enabled before you send another campaign email.

3. Rotate any key you have ever pasted into chat

Start with payment processors, email providers, analytics admin tokens, cloud access keys, and database passwords if they were ever shared casually.

4. Turn on HTTPS-only behavior

Force redirects from HTTP to HTTPS at the edge or host level so users never see insecure pages during ad clicks or form submits.

5. Create one basic uptime alert

Monitor the homepage plus your main conversion endpoint every 1 to 5 minutes from at least two regions if possible. Even one alert beats discovering downtime from angry customers later.

A simple redirect example helps when cleaning up old URLs:

return 301 https://example.com$request_uri;

Use this only when you know `example.com` is your canonical domain and you are not creating redirect loops through Cloudflare rules or app routing.

Where Cyprian Takes Over

If you want this handed off to a small team without security gaps hanging around in the background noise of launch week, this is where Launch Ready fits best:

• Domain - audit registrar ownership, DNS records, canonical hostnames.
• Email - configure SPF/DKIM/DMARC so transactional mail lands reliably.
• Cloudflare - enable proxying where appropriate plus SSL enforcement.
• Deployment - move the app into production with repeatable release steps.
• Secrets - remove exposed credentials from codebases and client bundles.
• Monitoring - add uptime checks so failures surface fast.
• Handover checklist - document access points so a small team can operate it without me in the loop every day.

My goal would be to leave you with a production-safe funnel that your founder-led team can actually maintain after handover.

A practical 48 hour plan looks like this:

• Hours 0-8: audit DNS, SSL state, email auth status, current deploy path.
• Hours 8-24: fix records, lock down Cloudflare/origin exposure, rotate obvious secrets.
• Hours 24-36: validate production deployment flow plus redirects and forms.
• Hours 36-48: add monitoring alerts, write handover notes, confirm pass/fail checklist with you.

If your funnel already has live traffic but fails any of these checks materially enough to threaten conversion or security exposure today should buy time by fixing it before scaling ads further.
