Launch Ready cyber security Checklist for automation-heavy service business: Ready for paid acquisition in marketplace products?.

What "ready" means for Launch Ready

For an automation-heavy service business selling into marketplace products, "ready" does not mean the site looks finished. It means a paid ad click can land on the domain, trust the brand, submit a lead or book a call, and trigger automations without exposing customer data or breaking deliverability.

I would call this ready only if all of the following are true:

• The primary domain resolves correctly with SSL on every entry point.
• Email is authenticated with SPF, DKIM, and DMARC passing.
• No secrets are exposed in the frontend, repo, logs, or deployment settings.
• Cloudflare is protecting the origin and rate limiting obvious abuse paths.
• Redirects, subdomains, and canonical URLs are consistent.
• Monitoring alerts you before customers do.
• The production flow survives paid traffic without broken forms, duplicate automations, or auth bypasses.

If any one of those fails, paid acquisition becomes expensive fast. You do not just lose conversions; you also buy support load, failed tracking, spam submissions, deliverability problems, and avoidable downtime.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain and SSL | Main domain and key subdomains load over HTTPS with no mixed content | Trust and browser safety | Ad clicks hit warnings or dead pages | | DNS hygiene | A, CNAME, MX, and TXT records are correct and documented | Routing and email delivery | Site outages and broken mail | | Redirects | One canonical URL per page with 301s only where needed | SEO and ad quality | Duplicate pages and tracking confusion | | Email auth | SPF, DKIM, DMARC all pass at reject or quarantine policy | Deliverability and spoofing defense | Emails go to spam or get forged | | Secrets handling | Zero exposed API keys or tokens in code, logs, or client bundles | Prevents account takeover and billing abuse | Data leaks and unauthorized access | | Cloudflare protection | WAF/rate limits enabled; origin IP not public where possible | Reduces attack surface | Bot abuse and origin overload | | Deployment safety | Production deploy is repeatable with rollback path | Avoids broken launches | Long outages during release | | Monitoring | Uptime checks plus alerting for key endpoints and email flow | Faster incident response | You find failures from customers first | | Cache behavior | Static assets cached; HTML strategy intentional; no stale auth data leaks | Performance under paid traffic | Slow pages and weird user sessions | | Handover docs | Runbook covers DNS, email, deploys, secrets, alerts, owners | Operational continuity | Founder dependency and mistakes |

The Checks I Would Run First

1. Domain resolution and SSL chain

Signal: every important URL returns a valid HTTPS response in under 2 seconds from multiple regions. I also check for mixed content warnings because they usually show up after launch when a script or image is still loaded over HTTP.

Tool or method: browser devtools, `curl -I`, SSL Labs test, Cloudflare dashboard.

Fix path: I would standardize the canonical domain first, then force 301 redirects from all variants to one clean entry point. If SSL is not issuing cleanly on apex and subdomains, I fix DNS first instead of guessing at app code.

2. Email authentication and sender reputation

Signal: SPF passes once per sending source, DKIM signs outbound mail correctly, and DMARC reports show alignment. For a marketplace product doing automation-heavy outreach or notifications, this is non-negotiable because bad mail setup kills onboarding flows.

Tool or method: MXToolbox checks, Google Postmaster Tools if available, mailbox seed tests.

Fix path: I would reduce sender sprawl. One verified sending domain is better than three half-configured ones that tank deliverability.

Example record pattern:

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

3. Secret exposure review

Signal: no API keys in frontend bundles, no tokens in public repos, no secrets in deployment logs. This is one of the fastest ways to turn ad spend into fraud spend because attackers can trigger third-party APIs on your bill.

Tool or method: secret scanning in GitHub/GitLab, grep over build output, browser source inspection.

Fix path: move all sensitive values to server-side environment variables or managed secret storage. Rotate anything that was ever exposed publicly. If you cannot prove rotation happened after exposure, assume compromise.

4. Cloudflare edge protection

Signal: WAF rules are active enough to stop obvious bot abuse while allowing real users through. Rate limits should cover login forms, contact forms, signup endpoints, webhook receivers if they are public-facing.

Tool or method: Cloudflare security events panel plus controlled abuse tests from a staging IP range.

Fix path: I would start with conservative rules around POST endpoints and admin paths. Then I tighten after observing false positives instead of locking out real leads on day one.

5. Production deployment repeatability

Signal: one-click or scripted deploy works twice in a row with the same result. A good release has rollback instructions that take minutes instead of hours.

Tool or method: CI pipeline review, dry-run deploy to staging then prod checklist review.

Fix path: remove manual steps that depend on memory. If deployment requires "the founder knows what to click," it is not production-safe for paid acquisition.

6. Monitoring on the actual revenue path

Signal: uptime checks watch homepage load time under 500ms TTFB target where feasible for static edges and under 500ms p95 API latency for core backend calls that power lead capture or booking. Alerts should cover homepage availability plus form submission failures.

Tool or method: UptimeRobot/Better Stack/Datadog synthetic checks plus application logs.

Fix path: monitor user-critical endpoints first. Watching only `/` while ignoring `/api/lead` is how teams miss silent conversion failure for days.

Red Flags That Need a Senior Engineer

1. You have multiple domains pointing at different versions of the product.

• This usually means bad redirects are already hurting ads and SEO.
• It also creates brand confusion when users see different URLs in emails versus the landing page.

2. You cannot explain where secrets live.

• If someone says "they are probably in env vars somewhere," that is a problem.
• That often means leaked keys are still active in old deploys or client code.

3. Your automation stack writes directly to customer-facing systems without retries.

• A single failed webhook can break onboarding silently.
• In marketplace products that means lost transactions and angry support tickets.

4. Email deliverability has never been tested across Gmail, Outlook, and Apple Mail.

• Many founders only test one inbox.
• Paid acquisition exposes every deliverability weakness immediately.

5. You do not have an owner for incidents.

• If uptime drops at 9 pm UTC after an ad campaign starts spending money,

someone needs to know whether to pause ads, roll back deploys, rotate credentials, or contact support.

• Without ownership you get wasted spend plus downtime.

DIY Fixes You Can Do Today

1. Verify your live URLs

• Open your main domain plus `www`, login pages, checkout pages if any,

booking pages, help pages, and every subdomain used by automation.

• Confirm they all end at one canonical HTTPS URL.

2. Run email tests

• Send test messages to Gmail and Outlook accounts you control.
• Check SPF/DKIM/DMARC results in the message headers before spending on ads.
• If DMARC is set to `none`, move it toward `quarantine` once aligned mail passes consistently.

3. Scan for exposed secrets

• Search your repo for `sk_`, `api_key`, `secret`, `token`, `.env`, webhook URLs,

private keys, Stripe keys, OpenAI keys, Twilio credentials, Supabase service roles, Firebase admin keys.

• Rotate anything suspicious immediately.

4. Turn on basic edge protection

• Enable Cloudflare proxying if your setup supports it.
• Add rate limits to form endpoints and admin routes.
• Block countries you never sell to only if you are certain it will not cut off real buyers.

5. Add two monitoring checks

• One for homepage availability.
• One for your primary lead capture endpoint or booking flow.
• Set alerts by email plus Slack so failures do not sit unnoticed overnight.

Where Cyprian Takes Over

Domain/email/Cloudflare/SSL/deployment/secrets/monitoring become one sprint instead of six half-finished tasks.

Here is how I map failures to deliverables:

| Failure found in checklist | What I do in Launch Ready | Timeline impact | |---|---|---| | Broken DNS or inconsistent redirects | Clean DNS records, set canonical redirects, validate subdomains | Hours 1-8 | | SSL issues or mixed content errors | Fix certificate chain and edge config; remove insecure asset loads if needed | Hours 1-8 | | Email auth failures | Configure SPF/DKIM/DMARC end-to-end; verify inbox delivery paths | Hours 4-12 | | Exposed secrets / weak env handling | Move secrets server-side; rotate compromised values; document storage locations | Hours 4-16 | | Missing Cloudflare protection | Enable WAF basics,DDoS protection,caching rules,and rate limits without blocking real users too aggressively! Actually we need ASCII punctuation only -> fix punctuation? let's continue carefully |

I would continue like this:

• Missing Cloudflare protection -> enable WAF basics,DDoS protection,caching rules,and rate limits without blocking real users too aggressively
• Fragile deployment -> set production deploy steps with rollback notes
• No monitoring -> add uptime checks plus alert routing
• No handover docs -> provide a checklist covering DNS,email,deployment,secrets,and owners

My default recommendation is simple: do not try to patch this piecemeal while running paid traffic at the same time. If there are more than two red flags above,I would buy the sprint rather than gamble on weekend fixes that can break lead flow during an ad run.
