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

What "ready" means for Launch Ready

For this product, "ready" means a B2B service business can take paid traffic, send invoices, run automations, and support customers without exposing data or breaking delivery.

I would call it ready only if all of these are true:

• Domain resolves correctly on every key subdomain.
• Email authentication passes with SPF, DKIM, and DMARC.
• Cloudflare is in front of the app with SSL enforced and no mixed content.
• Production deployment is live, monitored, and recoverable.
• Secrets are not exposed in the repo, logs, or frontend bundle.
• Redirects, caching, and DNS are correct enough that support does not get flooded by broken links or failed signups.
• Uptime alerts reach a human within 5 minutes.
• No critical auth bypasses, no exposed admin routes, and no public write access to internal systems.

If any one of those fails, you do not have support readiness. You have a live liability that will create ticket volume, lost leads, or data exposure.

Launch Ready is the kind of sprint I use when a founder has a working automation-heavy service business but the infrastructure is still held together by guesswork. The goal is to remove the failure modes that hurt trust, conversions, and operations first.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain and DNS | Root domain and key subdomains resolve correctly in under 60 seconds after changes | Customers need to reach the right app and email endpoints | Lost traffic, failed logins, broken onboarding | | SSL everywhere | HTTPS enforced with no mixed content warnings | Prevents browser warnings and session leakage | Users abandon checkout or login | | Email auth | SPF, DKIM, DMARC all pass on test sends | Protects deliverability and brand trust | Emails land in spam or get spoofed | | Cloudflare protection | Proxy enabled for public web assets with WAF/DDoS basics on | Reduces attack surface and downtime risk | Bot abuse, outages, noisy traffic | | Production deploy | App deploys cleanly with rollback path tested once | Lets you recover from bad releases fast | Extended downtime after a bad push | | Secrets handling | Zero secrets in frontend code, repo history cleaned where needed | Prevents account takeover and API abuse | Exposed Stripe keys, SMTP creds, admin tokens | | Environment variables | Prod env vars documented and scoped by environment | Keeps staging mistakes out of production | Wrong API endpoints or unsafe test data | | Monitoring alerting | Uptime checks alert within 5 minutes to email or Slack | Support readiness depends on fast detection | You hear about outages from customers first | | Redirects and canonicals | Old URLs redirect correctly with 301s only where intended | Preserves SEO and prevents broken journeys | Broken links, duplicate pages, lost leads | | Handover checklist | Owner knows who changes DNS, deploys code, rotates keys, and responds to alerts | Makes support operational after launch | Confusion during incidents and slow recovery |

The Checks I Would Run First

1. DNS and subdomain mapping

• Signal: Root domain works. `www`, app subdomain, API subdomain, mail-related records, and any client portal subdomains point where they should.
• Tool or method: `dig`, Cloudflare DNS panel review, browser checks from incognito mode.
• Fix path: I would clean up A/CNAME records, remove stale records from old hosts, confirm TTL values are reasonable for launch changes, then test propagation before handing off.

2. Email authentication end-to-end

• Signal: A test email passes SPF aligned with the sending service, DKIM signs correctly, and DMARC policy is at least monitoring mode with valid reports.
• Tool or method: MXToolbox checks plus a real send to Gmail/Outlook headers review.
• Fix path: I would align sender domains with your CRM or transactional provider, publish only one source of truth for SPF if possible to avoid lookup limits, then verify DMARC reporting before going live.

3. Secret exposure audit

• Signal: No API keys appear in frontend bundles, Git history visible branches do not contain live credentials on public repos.
• Tool or method: Repo scan with `git grep`, secret scanners like Gitleaks or TruffleHog, browser source inspection.
• Fix path: I would rotate any leaked keys immediately. Then I would move secrets into environment variables or a secret manager and remove them from build output.

4. Cloudflare security posture

• Signal: Proxy enabled for public traffic; SSL mode is correct; HTTP redirects to HTTPS; basic WAF rules block obvious abuse; DDoS protection is active.
• Tool or method: Cloudflare dashboard review plus curl checks for redirect behavior.
• Fix path: I would set SSL/TLS to full strict where origin certs support it. Then I would add simple rules for admin paths and rate-limit obvious abuse points like login forms.

5. Production deployment safety

• Signal: One-click deploy works without manual server edits; rollback is known; build logs are readable; failed deploy does not leave partial state.
• Tool or method: Staging-to-prod release test plus checking CI/CD logs.
• Fix path: I would separate build from release steps if they are tangled together. Then I would document rollback commands and make sure database migrations are backward compatible.

6. Monitoring coverage

• Signal: Uptime alerts fire within 5 minutes for homepage failure, login failure path if applicable, webhook endpoint failure if used in automations.
• Tool or method: Synthetic monitoring tools like Better Stack or UptimeRobot plus one alert delivery test.
• Fix path: I would add at least three checks: homepage HTTP 200/301 behavior, critical form submission endpoint response time under 500ms p95 where feasible, and webhook health if automation depends on it.

Red Flags That Need a Senior Engineer

1. You found live secrets in a frontend bundle or public repo This is not a cleanup task anymore. It means rotation strategy matters more than deletion because attackers may already have copied the key.

2. The app has admin functions behind weak auth or shared passwords If support staff can access customer data through a shared login pattern today, you need proper authorization design before launch.

3. There are multiple email senders fighting each other If your CRM sends invoices while your app sends onboarding emails from different domains without aligned SPF/DKIM/DMARC setup, deliverability will be unstable.

4. Production deploys require manual server edits That usually means config drift. One wrong command can take down the service during business hours.

5. Webhooks drive revenue-critical automations If failed webhooks stop lead routing or client notifications but there is no retry queue or dead-letter handling, you need engineering help now because missed events become missed revenue.

DIY Fixes You Can Do Today

1. Turn on HTTPS redirects everywhere Make sure every version of the site lands on one canonical HTTPS URL. This removes browser warnings and reduces duplicate content issues.

2. Check your email domain reputation basics Use MXToolbox to confirm SPF/DKIM/DMARC exist before sending another batch of outbound emails. If DMARC is missing entirely, add it in monitor mode first so you can see what breaks without blocking legitimate mail.

3. Rotate any password that looks shared If your team uses one password across hosting, email, or analytics, change it now. Shared credentials are how small incidents become full account compromises.

4. Remove secrets from visible places Search your frontend code for `sk_`, `pk_`, `api_key`, `secret`, `token`, `password`. Anything sensitive should move server-side immediately.

5. Set up one uptime check today Even a basic monitor on homepage availability is better than nothing. If you cannot detect downtime yourself, support readiness is already compromised.

A simple Cloudflare redirect rule can help prevent mixed entry points:

if (http.request.scheme eq "http") {
  redirect("https://" + http.host + http.request.uri.path)
}

Use this only if your origin logic already expects HTTPS traffic end to end.

Where Cyprian Takes Over

When founders bring me this kind of setup, I map failures directly to delivery items so we do not waste time debating theory.

• DNS problems -> I fix domain records,

subdomains, and redirects in the first 6 to 10 hours.

• Email deliverability gaps -> I configure SPF/DKIM/DMARC,

test real sends, and verify inbox placement in the next 4 to 6 hours.

• SSL / Cloudflare issues -> I enforce HTTPS,

set SSL mode correctly, and enable caching plus DDoS protection within day one.

• Deployment instability -> I clean up production deployment flow,

environment variables, and rollback safety within day one to day two.

• Secret exposure -> I identify exposed credentials,

rotate them, and move them into safe config storage immediately.

• Missing monitoring -> I add uptime checks,

alert routing, and handover notes before closeout.

The delivery window is 48 hours because this work should be concentrated while context is fresh. not a vague audit report, but actual fixes that reduce launch risk fast enough for a founder who needs support readiness now.

My usual handover includes:

• A pass/fail checklist for each item above
• A list of rotated secrets
• DNS records documented
• Monitoring targets confirmed
• Deployment notes for future releases
• A short owner guide for incident response

If you fail three or more items in the scorecard, I would not ship yet without intervention from someone senior enough to handle security trade-offs cleanly.
