Launch Ready cyber security Checklist for paid acquisition funnel: Ready for scaling past prototype traffic in internal operations tools?.

Opening

"Ready" for a paid acquisition funnel is not "the app loads on my laptop." It means a stranger can land on your pages, trust the domain, submit a lead or payment, and your internal operations tool can handle the traffic spike without exposing customer data or breaking the workflow.

For this product type, I would define ready as: no exposed secrets, no auth bypasses, SPF/DKIM/DMARC passing, SSL enforced everywhere, redirects clean, monitoring live, and the funnel can survive at least 10x prototype traffic without downtime. If your p95 API latency is over 500ms, your onboarding breaks on mobile, or your DNS and email setup are still "mostly working," you are not ready to scale spend.

Launch Ready is the service I would use when the business risk is not design polish but launch failure: broken domain trust, deliverability issues, failed app review-style checks for web apps, support overload from bad redirects, or a security incident caused by rushed deployment.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain ownership | Domain resolves to the correct production app with no stray records | Prevents traffic loss and spoofing | Users hit old environments or attacker-controlled hosts | | HTTPS everywhere | All pages and APIs force SSL with valid certs | Protects logins and form submissions | Browser warnings and stolen session data | | Redirects | One canonical path per page and no redirect chains over 2 hops | Preserves SEO and ad quality score | Higher bounce rate and wasted ad spend | | Cloudflare protection | DDoS protection and WAF rules enabled | Reduces bot abuse and volumetric attacks | Outages during campaign spikes | | Email authentication | SPF, DKIM, and DMARC all pass | Improves deliverability and trust | Leads land in spam or get spoofed | | Secrets handling | Zero secrets in code or client bundle | Prevents credential leaks | Database compromise or API abuse | | Environment separation | Dev, staging, and prod are isolated | Limits blast radius of mistakes | Test data leaks into production | | Uptime monitoring | Alerts fire within 5 minutes of downtime | Shortens outage detection time | You learn about failures from customers | | Logging hygiene | No PII or tokens in logs; auth events logged safely | Supports incident response without exposure | Sensitive data leaks through observability tools | | Deployment rollback | One-click rollback or known-good release path exists | Reduces release risk under traffic pressure | A bad deploy becomes an outage |

The Checks I Would Run First

1. Domain and DNS integrity

Signal: the apex domain and key subdomains resolve exactly where they should, with no orphaned A records, stale CNAMEs, or old preview hosts exposed.

Tool or method: I check DNS records directly in Cloudflare or your registrar, then verify with `dig`, browser tests, and a quick scan of subdomains like `www`, `app`, `api`, `mail`, and `admin`.

Fix path: remove stale records, set canonical redirects, lock registrar access with MFA, and make sure only production endpoints are public. If internal admin tools are exposed on public DNS by mistake, that is a hard stop.

2. SSL enforcement and secure headers

Signal: every route loads over HTTPS only, certificates renew automatically, and there is no mixed content on landing pages or dashboards.

Tool or method: I use browser devtools plus SSL checks from Cloudflare and a header scan to confirm HSTS, CSP basics, X-Frame-Options or frame-ancestors policy, and sane cache behavior.

Fix path: force HTTPS at the edge, redirect all HTTP traffic in one hop, renew certs automatically through Cloudflare or your host, and add security headers where they do not break the app. For paid funnels that collect leads or payments, this is non-negotiable.

3. Secrets exposure audit

Signal: zero secrets in Git history snapshots accessible to the app bundle; environment variables are server-side only; API keys are scoped tightly.

Tool or method: I search the repo for keys using secret scanners like GitHub secret scanning equivalents or local tools such as `gitleaks`, then inspect build output to ensure nothing sensitive ships to the browser.

Fix path: rotate anything exposed immediately, move secrets into server-only environment variables or managed secret stores, remove them from frontend code paths, and rebuild. If you already leaked a key publicly once, assume it is compromised.

4. Email deliverability setup

Signal: SPF passes alignment checks; DKIM signs outbound mail; DMARC is set to at least `p=none` during rollout with reporting enabled; sending domain matches your brand.

Tool or method: I test DNS records with mail validation tools plus actual message delivery into Gmail and Outlook to check spam placement and authentication results.

Fix path: publish correct TXT records for SPF/DKIM/DMARC at the root domain used for sending. For internal operations tools that send invites or alerts from acquisition flows, bad email setup creates silent revenue loss because users never receive access links.

5. Production deployment safety

Signal: production points to one known build artifact; rollback works; feature flags exist for risky changes; staging mirrors prod closely enough to catch failures before launch.

Tool or method: I inspect deployment settings in Vercel, Netlify, Cloud Run-like setups, Docker hosts, or CI pipelines. Then I run a smoke test against login, signup capture forms if any exist.

Fix path: freeze direct manual edits in production where possible. Use CI/CD with tagged releases so you can revert fast if conversion drops after launch.

6. Monitoring for uptime and abuse

Signal: you have uptime checks on home page plus critical funnel endpoints; alerting reaches Slack/email within 5 minutes; basic error tracking exists for frontend and backend failures.

Tool or method: I verify synthetic checks against `/`, `/login`, `/signup`, `/api/*` routes as relevant. Then I confirm logs capture status codes without leaking tokens or personal data.

Fix path: add health checks on every critical dependency path. For acquisition funnels scaling past prototype traffic in internal operations tools systems fail quietly first through queue delays and auth errors before they fully go down.

## Example DMARC record
_dmarc.example.com TXT "v=DMARC1; p=none; rua=mailto:dmarc@example.com; fo=1"

Red Flags That Need a Senior Engineer

1. Your app uses hardcoded API keys in frontend code or public config files. 2. You have no idea whether admin routes are protected beyond "it seems fine." 3. The same database backs dev/staging/prod with shared credentials. 4. Your funnel depends on third-party scripts you cannot explain or audit. 5. You have already launched ads but cannot tell me your p95 API latency under load.

If any of these are true, DIY fixes will be slower than buying help because every hour spent guessing increases launch delay risk. The real cost is not just engineering time; it is wasted ad spend when traffic hits broken infrastructure.

DIY Fixes You Can Do Today

1. Turn on MFA everywhere

Start with registrar accounts, Cloudflare login, hosting dashboard access, GitHub/GitLab access control panels,and email admin accounts. This removes the easiest takeover path before launch traffic arrives.

2. Remove unused public subdomains

Delete anything you do not actively use right now such as old previews,test environments,and abandoned admin hosts. Every extra public surface area becomes another place to misconfigure auth,CORS,and caching.

3. Check SPF,DKIM,and DMARC now

Send one test email from your funnel system to Gmail,and inspect whether authentication passes in message headers. If these fail,you will burn leads because messages land in spam or get rejected outright.

4. Rotate any secret you can see in plain text today

If an API key,is token,is webhook secret appears in code,screenshots,exports,and shared docs,treat it as compromised until proven otherwise. Rotate first,fight cleanup later,and do not wait for a perfect migration plan.

5. Set up one uptime monitor per critical route

Watch homepage,funnel entry page,and any authenticated endpoint required for conversion flow completion. Even a simple monitor that alerts after 2 failed checks gives you earlier warning than customer complaints.

Where Cyprian Takes Over

| Failure area | Launch Ready deliverable | What I do in 48 hours | |---|---|---| | Domain confusion | DNS cleanup plus redirects setup | Fix apex,www,and subdomain routing so traffic lands correctly | | Email trust issues | SPF,DKIM,and DMARC configuration | Publish records,test delivery,and reduce spam placement risk | | Weak edge security | Cloudflare setup plus DDoS protection | Put the funnel behind edge protection,caching,and SSL enforcement | | Broken deployment flow | Production deployment handover checklist | Confirm build,deploy,release,and rollback steps are safe | | Secret leakage risk | Environment variables plus secrets audit | Move secrets out of code,bundle,screenshots,and public configs | | No visibility after launch | Uptime monitoring setup + handover checklist | Add alerts so outages do not hide behind ad spend |

My sequence is simple:

1. Audit current state. 2. Fix highest-risk exposure first. 3. Deploy production-safe configuration. 4. Verify email,dns,and SSL end-to-end. 5. Hand over a checklist so you know what changed and what to watch next week.

If you need scaling past prototype traffic in an internal operations tool tied to paid acquisition,I would choose this route over trying to patch everything yourself between campaign launches. It reduces security risk,bad deliverability,and downtime without turning the project into a long rebuild.
