Launch Ready cyber security Checklist for automation-heavy service business: Ready for paid acquisition in B2B service businesses?.

What "ready" means for Launch Ready and paid acquisition

For this product, "ready" does not mean the site just loads and the forms work. It means a B2B service business can send paid traffic to the domain without exposing secrets, breaking email deliverability, or creating avoidable downtime when leads start arriving.

I would call it ready only if these are true:

• The main domain resolves correctly with SSL enforced.
• Redirects are clean and do not leak traffic to broken pages.
• SPF, DKIM, and DMARC all pass for outbound email.
• No production secrets are exposed in code, logs, or client-side bundles.
• Cloudflare is protecting the site with caching and DDoS controls enabled.
• Monitoring alerts you before a buyer notices the outage.
• The deployment path is repeatable and does not depend on one person's laptop.
• A lead can submit a form, get confirmation, and receive follow-up email without deliverability issues.

The point is to remove launch blockers that create security risk, support load, and conversion loss before you scale traffic.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | DNS ownership | Domain points to the correct app and apex/www rules are documented | Paid traffic must land on the right property | Traffic goes to parked pages or stale hosting | | SSL enforcement | HTTPS only, valid certs, no mixed content | Buyers will not trust insecure pages | Browser warnings and lower conversion | | Redirect hygiene | One-hop redirects where possible, no loops | Preserves SEO and ad tracking integrity | Broken landing pages and wasted clicks | | Email auth | SPF, DKIM, DMARC all passing | Needed for lead delivery and outbound trust | Emails land in spam or fail completely | | Secret handling | Zero exposed secrets in repo, logs, or frontend bundles | Prevents account takeover and data leaks | API abuse, billing fraud, data exposure | | Cloudflare setup | WAF/DDoS protection on, cache rules sane | Reduces attack surface and improves speed | Outages from bot traffic or trivial attacks | | Deployment safety | Production deploy is repeatable with rollback path | Avoids one-off manual mistakes | Broken releases during campaign launch | | Monitoring | Uptime alerts + error alerts active within 5 minutes | You need early warning when ads go live | Slow outages turn into lost leads | | Form flow security | Validation server-side, rate limits present | Lead forms get attacked first under paid traffic | Spam floods, abuse, database noise | | Handover quality | Owner knows credentials, access scope, and recovery steps | Security fails when nobody knows what exists | Lockout, dependency on contractor, delayed fixes |

The Checks I Would Run First

1. DNS and redirect chain audit

Signal: I want to see the apex domain, www subdomain, app subdomain if used, and any campaign landing pages all resolving exactly as intended. The redirect chain should be short: ideally one hop from http to https and from apex to canonical host.

Tool or method: I use `dig`, browser dev tools, and a redirect checker. I also test from multiple regions because DNS propagation issues can hide behind local cache.

Fix path: I correct nameservers first if needed, then set canonical host rules. I remove chained redirects like `http -> https -> www -> /home -> /landing-page` because they waste ad clicks and create room for breakage.

2. SSL certificate and mixed content check

Signal: HTTPS must be valid on every public route. There should be no mixed content warnings from images, scripts, fonts, or embeds loading over HTTP.

Tool or method: Browser console inspection plus a crawl of core pages. I also check certificate expiry so you do not discover a failure during an ad push.

Fix path: Force HTTPS at the edge with Cloudflare or origin config. Then replace hardcoded HTTP asset URLs in templates or CMS content.

3. Email authentication check

Signal: SPF should authorize your sending service. DKIM should sign messages correctly. DMARC should pass with at least `p=none` during setup and move toward stricter policy once stable.

Tool or method: I use MXToolbox-style checks plus test sends to Gmail and Outlook. I look at headers because inbox placement is where B2B follow-up wins or dies.

Fix path: Add the exact DNS records required by your mail provider. Then test transactional emails separately from marketing emails so one broken stream does not contaminate the other.

A simple example looks like this:

v=spf1 include:_spf.google.com include:sendgrid.net ~all

That line is not universal. It only works if those providers are actually part of your sending stack.

4. Secrets exposure review

Signal: There should be zero API keys in frontend code, public repos, build artifacts, screenshots, error logs, or shared docs. If a secret has been committed once without rotation after exposure risk was high.

Tool or method: I scan git history with secret search tools and inspect environment variable usage in deployment settings. I also check client bundles because AI-built apps often leak keys into browser code by accident.

Fix path: Move all secrets server-side or into managed environment variables. Rotate any exposed credential immediately. If a key touched production data or billing systems, assume compromise until proven otherwise.

5. Cloudflare edge security review

Signal: Cloudflare should sit in front of the app with DNS proxied where appropriate, WAF enabled if available on plan level, bot filtering considered for forms, SSL mode set correctly between edge and origin, and caching rules tuned so dynamic pages do not get cached accidentally.

Tool or method: I inspect Cloudflare dashboard settings plus origin response headers. I test whether direct-origin access is blocked if that is part of your design.

Fix path: Lock down origin access where possible using firewall rules or authenticated origin pulls. Cache static assets aggressively but keep authenticated areas private.

6. Deployment pipeline and rollback check

Signal: A production deploy should be reproducible from source control with clear environment separation between dev and prod. There must be a rollback path that takes minutes rather than hours.

Tool or method: I review build logs, environment variable mapping, release notes discipline, and whether someone can redeploy without tribal knowledge.

Fix path: Remove manual steps that only one person knows how to do. Add a tagged release process or one-click deploy with rollback instructions documented in plain English.

Red Flags That Need a Senior Engineer

1. You have paid traffic planned but no one can explain where secrets live. That is how customer data leaks happen after launch when forms start getting real volume.

2. Your current setup depends on copy-pasting environment variables between platforms. That creates drift between staging and production and makes outages hard to diagnose.

3. Email deliverability has never been tested with real inboxes. In B2B service businesses this means lead follow-up silently fails while you think marketing is working.

4. The app uses multiple builders or plugins without an owner for security review. AI-built stacks often accumulate hidden dependencies fast enough that nobody understands the attack surface anymore.

5. You already saw one broken deploy during internal testing. If it failed with low traffic now it will fail harder under ad spend later.

DIY Fixes You Can Do Today

1. Verify your main domain routes correctly. Check apex `example.com`, `www.example.com`, and any campaign subdomains manually in an incognito window.

2. Turn on HTTPS everywhere. If you see any page loading over HTTP assets after login-free browsing tests, fix those URLs before spending on ads.

3. Test outbound email headers. Send a message to Gmail and inspect SPF/DKIM/DMARC results in the message details panel.

4. Rotate any key you have ever pasted into chat tools or screenshots. If there is any doubt about exposure history then rotate it now rather than after launch pain starts.

5. Set up basic monitoring today. Use uptime checks for homepage plus form submission flow so you know within 5 minutes if something breaks overnight.

Where Cyprian Takes Over

If you find failures in DNS ownership, redirect chains, SSL enforcement,, email authentication,, secret handling,, Cloudflare hardening,, deployment safety,, or monitoring,, Launch Ready covers them directly inside the 48 hour sprint.

Here is how I would map it:

| Failure found | Service deliverable | |---|---| | Wrong domain routing or messy redirects | DNS cleanup plus redirect configuration | | SSL errors or mixed content warnings | SSL setup plus edge/origin correction | | No SPF/DKIM/DMARC passing | Email authentication records configured | | Exposed secrets or weak environment handling | Secrets audit plus environment variable cleanup | | No DDoS protection or weak caching layer | Cloudflare setup with caching rules | | Manual deploys with no rollback plan | Production deployment hardening | | No alerting when things fail | Uptime monitoring setup | | No handover docs after launch prep | Handover checklist with access summary |

My recommendation is simple: do not buy ads until these items are closed out if you have any doubt about launch safety.

If you want me to own this end-to-end,, I would treat it as a short rescue sprint:

• Hour 0 to 8: audit DNS,, SSL,, email auth,, secrets,, deployment
• Hour 8 to 24: fix critical blockers
• Hour 24 to 36: verify monitoring,, caching,, redirects,, forms
• Hour 36 to 48: handover checklist,, validation pass,, go-live support

That gets you from "looks live" to "safe enough for paid traffic."
