Launch Ready cyber security Checklist for paid acquisition funnel: Ready for support readiness in bootstrapped SaaS?

When I say a paid acquisition funnel is "ready" for support readiness, I mean this: a stranger can click an ad, land on your page, trust the domain, submit payment or sign up, get the right email follow-up, and not create a fire drill for your team.

For a bootstrapped SaaS, that means no exposed secrets, no broken DNS, no spoofable email domain, no weak redirects, no missing SSL, no unmonitored downtime, and no obvious path for attackers to abuse your signup or contact forms. If one of those fails, you do not just risk a security issue. You risk wasted ad spend, broken conversion tracking, support tickets you cannot answer fast enough, and customer trust damage before you even reach product-market fit.

My bar for "ready" is simple:

• Domain resolves correctly.
• SSL is valid everywhere.
• SPF, DKIM, and DMARC all pass.
• No critical auth bypasses or exposed secrets.
• Uptime monitoring is active.
• Redirects and subdomains are intentional.
• The funnel can handle traffic spikes without falling over.
• Support handover is documented so the next person knows what to check first.

If you cannot confidently say yes to those items today, the funnel is not support-ready yet.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain ownership | Registrar access confirmed and 2FA enabled | Prevents hijack and accidental DNS changes | Traffic loss, phishing risk | | SSL everywhere | All public pages return valid HTTPS with no mixed content | Protects trust and prevents browser warnings | Lower conversion, blocked forms | | Redirects | HTTP to HTTPS and apex to primary domain are correct | Keeps ads and SEO clean | Duplicate content, tracking drift | | Subdomains | Only approved subdomains resolve publicly | Reduces attack surface | Exposed admin tools or staging apps | | Email auth | SPF, DKIM, DMARC pass with aligned From domain | Stops spoofing and improves deliverability | Emails land in spam or get forged | | Secrets handling | Zero secrets in repo or client-side code | Prevents account takeover and data leaks | Credential theft, production breach | | Monitoring | Uptime alerts active with 5 minute checks max | Detects outages before customers do | Silent downtime and missed leads | | Caching/CDN | Cloudflare caching rules are intentional and tested | Improves speed under ad traffic spikes | Slow pages, higher bounce rate | | Form protection | Rate limits or anti-abuse controls on forms/API routes | Stops spam and bot abuse | Support overload, fake leads | | Handover docs | Runbook includes DNS, deploys, rollback, contacts | Makes support fast during incidents | Slow recovery and founder dependency |

The Checks I Would Run First

1. DNS and domain control

• Signal: The apex domain points where you expect it to point, www redirects correctly, and old records are removed.
• Tool or method: `dig`, Cloudflare DNS dashboard, registrar audit.
• Fix path: I would confirm registrar lock plus 2FA first. Then I would clean stale A, CNAME, MX, TXT records so only live services remain.

2. SSL and mixed content

• Signal: Every public page loads over HTTPS with a valid certificate and no browser console warnings about insecure assets.
• Tool or method: Browser dev tools, SSL Labs test, Cloudflare SSL/TLS settings.
• Fix path: I would force HTTPS at the edge, update hardcoded asset URLs to HTTPS or relative paths, then retest checkout and signup flows.

3. Email authentication

• Signal: SPF passes for your sending provider, DKIM signs outgoing mail correctly, and DMARC is set to at least quarantine with alignment working.
• Tool or method: MXToolbox checks plus a real test email to Gmail and Outlook.
• Fix path: I would publish the correct TXT records in DNS and verify that your transactional provider is using the same From domain as your brand.

4. Secrets exposure

• Signal: No API keys or private tokens appear in the repo history, frontend bundle, logs, or environment screenshots.
• Tool or method: GitHub secret scanning if available plus manual grep across source files and build output.
• Fix path: I would rotate any exposed key immediately. Then I would move all sensitive values into server-side environment variables and remove them from client code.

5. Form abuse resistance

• Signal: Signup forms do not accept unlimited requests from one IP or bot pattern. Error messages do not reveal internal details.
• Tool or method: Manual submission testing plus rate-limit inspection in app routes or WAF rules.
• Fix path: I would add basic rate limiting on lead capture endpoints. If needed, I would add CAPTCHA only where abuse is real because too much friction kills conversion.

6. Monitoring and alerting

• Signal: You get alerted within 5 minutes if the site goes down or the checkout flow errors spike.
• Tool or method: UptimeRobot or Better Stack plus synthetic checks against landing page and form submission endpoints.
• Fix path: I would set alerts on homepage availability, critical API health endpoints if present,

and key funnel pages so outages show up before ad spend compounds the damage.

Red Flags That Need a Senior Engineer

1. You found secrets in source control history

• If a Stripe key, OpenAI key, database password, or SMTP credential was ever committed publicly or shared in client-side code,

stop patching around it. Rotate everything first.

2. Your funnel depends on multiple third-party tools with unclear ownership

• If Webflow talks to Zapier which talks to Airtable which talks to Make which talks to your backend,

one broken integration can quietly kill lead capture while ads keep spending money.

3. Staging is reachable from the public internet

• If test environments are indexed or discoverable through subdomains,

you may be exposing unfinished features, admin panels, debug endpoints, or weaker authentication than production.

4. You have custom auth logic without tests

• If login resets,

magic links, invite flows, role checks, or webhook handlers were built quickly by AI tooling without regression tests, one small change can create an auth bypass.

5. You cannot explain your deploy rollback path

• If production breaks during launch traffic and nobody knows how to revert safely within 10 minutes,

you are not support-ready yet.

DIY Fixes You Can Do Today

1. Turn on registrar 2FA now

• Protect the domain first because everything else depends on it.
• Use an authenticator app instead of SMS if possible.

2. Check every public URL over HTTPS

• Open your homepage,

pricing page, signup page, checkout page, privacy policy, terms, help center, and thank-you page in an incognito window.

• Look for certificate warnings,

broken images, mixed content, weird redirects, or localhost references.

3. Audit your email sender settings

• Confirm SPF includes only trusted senders.
• Confirm DKIM is enabled in your provider.
• Add DMARC even if you start with `p=none` for visibility before tightening it.

4. Search for secrets before they leak

• Scan `.env`,

frontend config files, build scripts, README files, issue trackers, screenshots, pasted logs, and old commits.

• If anything looks like a token or password,

assume it is compromised until rotated.

5. Set one uptime monitor today

• Start with homepage availability plus one critical funnel endpoint.
• Alert yourself by email plus Slack if possible so downtime does not sit unnoticed overnight.

Here is a minimal DMARC record pattern that helps most bootstrapped SaaS teams start safely:

v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com; adkim=s; aspf=s

That does not solve everything by itself. It does give you visibility into spoofing attempts while reducing the chance that forged mail gets treated as legitimate.

Where Cyprian Takes Over

• I take over DNS cleanup so the funnel points exactly where it should.
• I configure redirects so ads land on one canonical URL path only.
• I harden Cloudflare settings for SSL enforcement,caching,and DDoS protection without breaking checkout behavior.
• I verify SPF,DKIM,and DMARC so transactional mail actually reaches inboxes instead of spam folders.
• I review deployment settings so production builds use environment variables correctly and secrets never ship to the browser.
• I set uptime monitoring so failures trigger alerts fast enough to protect paid traffic spend.
• I hand back a checklist so support knows what to check first when something fails.

My delivery sequence is usually:

• Hour 0 to 8: audit current state,domain,email,and live risks
• Hour 8 to 24: fix DNS,rewrite redirects,and lock down SSL/Cloudflare
• Hour 24 to 36: verify deployment,secrets,and monitoring
• Hour 36 to 48: run final checks,handover notes,and launch confirmation

If there are multiple failures across domain,email,deployment,and monitoring,I would not recommend piecemeal DIY cleanup unless you already have strong infra experience.
