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

What "ready" means for Launch Ready

For an automation-heavy B2B service business, "ready" does not mean "the site loads." It means a buyer can land on your domain, trust the brand, submit a lead or onboarding form, receive the right email, and move into your delivery workflow without exposing customer data or breaking your funnel.

For this product and outcome, I would call it ready only if all of these are true:

• The main domain resolves correctly over HTTPS with no mixed-content warnings.
• Email from your domain passes SPF, DKIM, and DMARC.
• Customer onboarding forms and automations are protected from spam, abuse, and accidental data leaks.
• Secrets are not hardcoded in the app, repo, or frontend bundle.
• Cloudflare is configured for caching, WAF, and DDoS protection.
• Production deploys are repeatable and monitored.
• You can detect downtime before a customer tells you.
• The first user journey works on mobile and desktop with no broken redirects or dead ends.

If any one of those fails, you are not launch-ready. You are gambling with lost leads, support tickets, deliverability problems, and avoidable security incidents.

The scope is domain, email, Cloudflare, SSL, deployment, secrets, monitoring, and handover so a founder can start customer onboarding with less risk.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | HTTPS everywhere | All key pages load on `https://` with valid certs | Buyers need trust before submitting forms | Browser warnings, lower conversion | | Redirects | One canonical version of each URL | Prevents SEO split and routing bugs | Duplicate pages, broken links | | SPF/DKIM/DMARC | All pass for sending domain | Keeps onboarding emails out of spam | Missed leads, failed notifications | | Secrets handling | No secrets in repo or client bundle | Stops credential leaks and abuse | Account takeover, data exposure | | Cloudflare protection | WAF and DDoS enabled | Reduces bot traffic and attacks | Form spam, downtime, higher support load | | Uptime monitoring | Alerts fire within 1 to 5 minutes | Detects issues before customers do | Silent outages and delayed response | | Deployment process | Repeatable deploy with rollback path | Prevents risky manual pushes | Broken release during business hours | | Caching strategy | Static assets cached correctly | Improves speed under load | Slow pages, poor conversion | | Subdomains set up | App, API, mail-related subdomains work cleanly | Keeps services separated and manageable | Misroutes, auth issues, mail failures | | Handover checklist | Owner knows DNS records, login access, and recovery steps | Avoids vendor lock-in and confusion | Delayed fixes when something breaks |

The Checks I Would Run First

1. Domain and redirect integrity

• Signal: `http://`, `https://`, `www`, root domain, and subdomains all resolve as intended with one canonical path.
• Tool or method: `curl -I`, browser tests, DNS lookup tools like `dig`, plus manual click-through on the top 10 landing paths.
• Fix path: I would remove redirect chains longer than one hop where possible. I would enforce one canonical host in Cloudflare or the app router so users do not bounce between variants.

2. Email authentication

• Signal: SPF passes for sending providers; DKIM signs outbound mail; DMARC is set to at least `p=quarantine` once tested. If you are already live and stable enough for enforcement, move to `p=reject`.
• Tool or method: MXToolbox checks, Google Postmaster Tools if available, provider dashboards like SendGrid or Resend.
• Fix path: I would align the From domain with the actual sending service. If marketing emails come from one provider and transactional mail from another, I would split them cleanly instead of mixing settings.

3. Secrets exposure review

• Signal: no API keys in frontend code, no `.env` files committed to git history if avoidable today without a cleanup plan later.
• Tool or method: repo scan with secret search tools like GitHub secret scanning or TruffleHog; inspect build output; check browser network payloads for leaked values.
• Fix path: Move every sensitive value server-side or into deployment environment variables. Rotate anything exposed immediately. A leaked key is not a styling issue; it is an incident.

4. Cloudflare security posture

• Signal: WAF enabled for obvious attack patterns; rate limits on form endpoints; bot protection where relevant; SSL mode set correctly.
• Tool or method: Cloudflare dashboard review plus test submissions from different IPs and browsers.
• Fix path: I would lock down public endpoints first. If your onboarding form receives spam or credential stuffing attempts after launch week one will be worse than week zero unless rate limiting is in place.

5. Production deployment safety

• Signal: deploys are repeatable from source control with clear environment separation between staging and production.
• Tool or method: inspect CI/CD pipeline logs; run a dry deploy; confirm rollback works in under 10 minutes.
• Fix path: I would remove manual copy-paste deployments where possible. Manual deploys create silent drift and make incidents harder to reverse.

6. Monitoring coverage

• Signal: uptime checks exist for homepage plus critical onboarding flows; alerts go to email or Slack within 1 to 5 minutes; basic error logging exists.
• Tool or method: UptimeRobot, Better Stack,

Sentry, or similar monitoring tools; trigger test failures intentionally.

• Fix path: I would monitor the real customer journey rather than only the homepage. A site can be "up" while forms fail and payments break.

Red Flags That Need a Senior Engineer

1. You cannot explain where secrets live

• If nobody knows which keys are public vs private, you have a production risk already.

2. Customer onboarding depends on multiple automations with no owner

• If form submission triggers CRM updates,

Slack alerts, email sequences, and internal task creation, one broken integration can stop revenue flow.

3. The site has been edited by multiple tools

• Lovable,

Bolt, Cursor, Webflow, and custom scripts often leave behind conflicting configs that only show up during deploy.

4. Email deliverability has already been flaky

• If welcome emails land in spam now,

they will get worse after you increase volume.

5. There is no rollback plan

• If a bad deploy means downtime until someone manually fixes it,

you need senior help before launch day.

DIY Fixes You Can Do Today

1. Check every public URL

• Open the root domain,

login page, contact form, and onboarding flow on mobile and desktop.

• Confirm each one uses HTTPS only.

2. Verify email DNS records

• Use an MX lookup tool to confirm SPF,

DKIM, and DMARC exist for your sending domain.

• If DMARC is missing,

add it now in report-only mode first if you are unsure.

3. Rotate any key you pasted into chat tools or screenshots

• Assume anything shared casually may be exposed later.
• Replace old keys before launch if there is any doubt.

4. Turn on basic uptime monitoring

• Set alerts for homepage,

signup page, and the primary API endpoint if you have one.

• Ask for notification by both email and Slack if possible.

5. Remove obvious public credentials from frontend code

• Search your repo for strings that look like keys,

tokens, or private URLs.

• Anything starting with `sk_`, `pk_`, `Bearer`, or similar deserves a second look.

A simple rule helps here: if a secret must never reach the browser but appears in client-side code once built,

it is already too late.

Where Cyprian Takes Over

This is where Launch Ready becomes worth buying instead of piecing together half-fixes over several nights.

If your checklist failures include DNS confusion, email authentication gaps, SSL problems, unsafe redirects, or missing subdomains,

I handle those inside the 48-hour sprint by cleaning up DNS records, setting canonical redirects, configuring Cloudflare, issuing SSL correctly,

and making sure traffic lands where it should without breaking trust signals.

If your failures include exposed secrets,

I move sensitive values out of the frontend,

set up environment variables properly,

rotate compromised credentials,

and verify nothing sensitive ships in the build output.

If your failures include weak monitoring or no operational visibility,

I add uptime checks,

basic alerting,

and a handover checklist so you know what to watch after launch instead of guessing when something breaks.

If your failures include production deployment risk,

I make the deployment repeatable,

document the release path,

and leave you with clear ownership of access,

rollback steps,

and next actions.

My recommendation is simple:

if this product touches real customer onboarding,

do not treat cyber security as an optional polish pass.

Buy the sprint when there is even one unknown around secrets,

email deliverability,

support time,

and damage control.
