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

What "ready" means for Launch Ready

For this product, "ready" does not mean the site looks finished. It means a B2B service business can send traffic to it, trust the domain and email setup, and not worry that one bad config exposes customer data or breaks delivery.

If I were self-assessing, I would want all of this true before app review or launch:

• The domain resolves correctly with no broken redirects.
• SSL is valid everywhere, including subdomains.
• Cloudflare is in place with sane security settings.
• SPF, DKIM, and DMARC all pass for outbound email.
• No secrets are exposed in code, logs, or deployment settings.
• Production deployment works from a repeatable process, not manual guesswork.
• Uptime monitoring is active and alerts the right person.
• The handover checklist is complete enough that a founder can operate without me.

For an automation-heavy service business, cyber security risk is not abstract. A bad DNS record can break lead capture, a leaked API key can rack up bills or expose client data, and weak email authentication can send your sales emails to spam. If app review is the goal, the bar is simple: no obvious security gaps, no broken infrastructure dependencies, and no launch-day surprises.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain ownership | Domain points to the right app and registrar access is secured | Prevents hijacks and accidental downtime | Site outage, phishing risk, lost leads | | SSL coverage | All primary domains and subdomains serve valid HTTPS | Protects login forms and trust signals | Browser warnings, blocked forms | | Redirects | HTTP to HTTPS and non-canonical URLs redirect once only | Avoids duplicate content and tracking issues | SEO dilution, broken auth callbacks | | Cloudflare setup | WAF/DDoS protection enabled with sensible rules | Reduces attack surface and bot abuse | Traffic spikes, spam submissions | | Email auth | SPF, DKIM, DMARC all pass with aligned domains | Improves deliverability for sales and ops email | Spam folder placement, failed outreach | | Secrets handling | Zero secrets in repo, logs, or frontend bundles | Stops credential theft and account abuse | Data exposure, billing abuse | | Deployment process | Production deploy is repeatable and documented | Reduces human error during launch | Broken release, rollback delay | | Monitoring | Uptime checks + alerting on key endpoints are active | Detects outages before customers do | Silent downtime, missed revenue | | Caching/performance | Core pages load fast enough for mobile users | Supports conversion and lowers bounce rate | Slow lead gen pages, wasted ad spend | | Handover readiness | Owner has checklist for DNS, email, deploys, support contacts | Makes the business operable after handoff | Dependency on one person |

A practical threshold I use: homepage LCP under 2.5 seconds on mobile for main landing pages, p95 API response under 500 ms for core actions where applicable, and zero exposed secrets in public repos or client-side code.

The Checks I Would Run First

1. DNS and domain control

• Signal: The site loads from the canonical domain only, old domains redirect cleanly once, and registrar access uses MFA.
• Tool or method: DNS lookup tools, registrar audit, browser checks for redirect chains.
• Fix path: Clean up A/AAAA/CNAME records, remove stale records from old hosts, lock registrar access with MFA and recovery codes stored safely.

2. SSL coverage across every entry point

• Signal: No mixed content warnings, no expired certs, no subdomain left on HTTP.
• Tool or method: Browser dev tools, SSL Labs test, curl against main domain and subdomains.
• Fix path: Issue certificates for all needed hostnames through Cloudflare or your host. Force HTTPS at the edge and remove insecure asset links.

3. Email authentication health

• Signal: SPF passes with one authoritative sender path only; DKIM signs mail; DMARC passes in alignment mode.
• Tool or method: Mail-tester style checks plus DNS record inspection.
• Fix path: Publish a single SPF record that matches reality. Enable DKIM on your sending platform. Start DMARC at `p=none`, then move to `quarantine` after validation.

A minimal example: ```txt v=spf1 include:_spf.google.com include:sendgrid.net -all ```

4. Secrets exposure review

• Signal: No API keys in frontend bundles, Git history, CI logs, or public environment files.
• Tool or method: Repo scan with secret detection tools plus manual search for `sk_`, `api_key`, `token`, `.env`.
• Fix path: Rotate anything exposed immediately. Move secrets to server-side environment variables or a managed secret store. Rebuild deployed artifacts after cleanup.

5. Cloudflare security posture

• Signal: WAF enabled where appropriate; rate limits exist on login/contact endpoints; bot traffic is controlled.
• Tool or method: Cloudflare dashboard review plus endpoint testing from a fresh browser session.
• Fix path: Add challenge rules for abusive paths only. Do not block real buyers with aggressive rules. Protect forms from spam without adding friction to legitimate users.

6. Production deployment sanity

• Signal: One documented release path exists from source to production with rollback steps tested once.
• Tool or method: Dry-run deploy from staging if available; inspect CI/CD logs; confirm environment parity.
• Fix path: Standardize build commands and environment variables. Remove manual production edits. Add a rollback checklist so a bad release does not turn into a half-day outage.

Red Flags That Need a Senior Engineer

1. Secrets were already leaked If an API key was committed publicly or pasted into chat tools without rotation after exposure, I would not DIY this lightly. One missed key rotation can become data loss or cloud billing abuse.

2. Email deliverability is already failing If sales emails are landing in spam or DMARC reports show misalignment across providers like Google Workspace plus a CRM tool plus marketing automation software at the same time? That usually means the sender architecture needs proper cleanup.

3. The app uses multiple automations touching customer data When workflows span webhooks, third-party APIs, internal admin panels, and scheduled jobs as part of one customer journey? Small mistakes create duplicate actions,, data leaks,, or unauthorized updates.

4. There are custom auth flows Magic links,, SSO,, invitation systems,, role-based access,, or tenant isolation issues deserve senior review fast. A broken authorization rule can expose one client's records to another client.

5. You are about to spend on ads If paid traffic starts before monitoring,, caching,, redirects,, and form handling are stable? You will waste ad spend on broken sessions,, slow pages,, and invisible failures that never reach your inbox.

DIY Fixes You Can Do Today

1. Turn on MFA everywhere Secure registrar,, Cloudflare,, hosting,, email provider,, GitHub/GitLab,, CRM,. If one account gets taken over,, the whole launch can be derailed.

2. Inventory every secret List all API keys,, webhooks,, SMTP creds,, OAuth apps,. Rotate anything you cannot explain clearly., If you do not know where a key is used,, assume it should be replaced.

3. Check SPF/DKIM/DMARC now Use your email provider's admin console plus a DNS checker., If any record fails validation,, fix it before sending more outreach., Deliverability problems get worse when volume increases.

4. Review redirect chains Test your main domain,,, www,,, old campaign URLs,,, payment callback URLs,. Make sure each one lands in one hop on the right page., Long chains hurt performance and sometimes break logins.

5. Add basic uptime monitoring Monitor homepage,,, contact form,,, login page,,, checkout or booking flow,. Set alerts to email plus Slack if possible., A 10-minute outage during launch can still cost leads if nobody notices.

Where Cyprian Takes Over

Here is how I map common checklist failures to the service deliverables:

| Failure found in audit | Deliverable included in Launch Ready? | What I would do in 48 hours | |---|---|---| | Broken DNS or wrong canonical domain | Yes: DNS + redirects + subdomains + deployment support | Correct records,,, validate propagation,,, test redirect behavior end-to-end | | Missing SSL on primary domain or subdomains | Yes: Cloudflare + SSL setup | Issue certs,,, force HTTPS,,, remove mixed content blockers | | Weak bot protection / DDoS exposure | Yes: Cloudflare + DDoS protection + caching guidance | Configure edge protection,,, reduce noisy traffic,,, preserve real users | | Email authentication failures | Yes: SPF/DKIM/DMARC setup | Align sender domains,,, publish records,,, verify pass status | | Secrets exposed in code or deployment config | Yes: secrets handling + production hardening guidance | Rotate keys,,, move secrets server-side,,, rebuild safely | | No repeatable production deployment process | Yes: production deployment + handover checklist | Standardize release steps,,, document rollback,,,, confirm owner access | | No monitoring after launch plan exists too late to help ops team? Wait let's rewrite cleanly |

If there is no monitoring plan yet:

• Yes: uptime monitoring included
• Action: set alerts on critical routes like homepage,,,, login,,,, forms,,,, booking,,,, checkout
• Result: you know about outages before customers do

My recommendation is simple:

• If you have one or two isolated issues like an SPF record typo,,,, fix them yourself today.
• If you have multiple failures across DNS,,,, email,,,, secrets,,,, deployment,,,, then buy the sprint instead of patching around it.
• If app review depends on reliability evidence,,,, let me clean up the stack first so you are not fighting preventable rejections later.

The delivery window is 48 hours because this work should be focused., Not endless., The goal is a production-safe handover with clear ownership boundaries so your team can keep moving without recurring fire drills.
