Launch Ready cyber security Checklist for automation-heavy service business: Ready for first 100 users in founder-led ecommerce?.

What "ready" means for a founder-led ecommerce automation business

For this kind of product, "ready" does not mean perfect. It means a first 100 users can sign up, pay, receive emails, and use the core flow without exposing customer data or breaking the business.

If I were auditing this for launch, I would want five things to be true:

• The domain resolves correctly, redirects are clean, and SSL is valid everywhere.
• Email deliverability is working, with SPF, DKIM, and DMARC passing.
• Production deployment is stable, secrets are not exposed, and environment variables are separated from source code.
• Basic Cloudflare protection is on, including caching and DDoS mitigation.
• Monitoring exists so you know within minutes if checkout, login, or automations fail.

For the first 100 users, the bar is simple: no critical auth bypasses, zero exposed secrets, p95 API latency under 500ms for core requests, and no broken onboarding path. If any of those fail, you are not launch-ready. You are gambling with ad spend, support load, and reputation.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain setup | Root domain and www redirect correctly in one direction | Prevents duplicate content and trust issues | SEO split, broken links, confused users | | SSL | HTTPS works on all pages and subdomains | Protects logins and checkout data | Browser warnings, abandoned sessions | | Email auth | SPF, DKIM, DMARC all pass | Keeps onboarding and order emails out of spam | Missed receipts, failed password resets | | Secrets handling | Zero secrets in repo or frontend bundle | Prevents account takeover and vendor abuse | API theft, leaked admin access | | Deployment safety | Production deploy uses locked env vars and rollback path | Reduces outage risk during release | Downtime during launch window | | Cloudflare protection | WAF/rate limits/DDoS rules active | Shields forms and APIs from abuse | Bot spam, brute force attacks | | Redirect hygiene | Old URLs redirect with 301 only where intended | Preserves SEO and user flow | Broken checkout links, lost traffic | | Monitoring | Uptime checks on homepage, login, checkout, webhook endpoints | Detects failure before customers do | Silent outages and support chaos | | Logging hygiene | No passwords/tokens/PII in logs | Limits data exposure after incidents | Compliance risk and breach scope expansion | | Recovery plan | Backup or rollback tested once before launch | Makes failure survivable | Long outage after a bad deploy |

The Checks I Would Run First

1. Domain and redirect integrity

Signal: The root domain loads once only, www either redirects to non-www or the reverse consistently, and there are no redirect loops.

Tool or method: I check DNS records in Cloudflare or your registrar, then test with curl and browser dev tools. I also inspect canonical tags if the site has marketing pages.

Fix path: Set one canonical host. Use 301 redirects only. Remove conflicting rules at the registrar, hosting provider, or app router. If you have multiple platforms touching DNS, I consolidate ownership so one system controls the final route.

2. SSL coverage across every public surface

Signal: Every public page returns HTTPS with a valid certificate. Subdomains like app., api., mail., or admin. do not throw certificate errors.

Tool or method: I test with browser security panels plus SSL Labs for certificate chain quality. I also check mixed content warnings in the console.

Fix path: Issue certificates through Cloudflare or your host. Force HTTPS at the edge. Replace hardcoded http:// links inside templates and email assets. If your app serves assets from another origin without TLS support, that gets fixed before launch.

3. Email authentication for deliverability

Signal: SPF passes for your sending provider; DKIM signs outgoing mail; DMARC policy exists and aligns with your From domain.

Tool or method: I inspect DNS records directly and send test emails to Gmail and Outlook to verify headers. I also use mailbox placement checks if onboarding depends on transactional email.

Fix path: Add correct TXT records for SPF and DMARC. Enable DKIM signing in your email platform. Set DMARC to p=none first if you are unsure about alignment, then tighten after validation.

A minimal DMARC record looks like this:

_dmarc.yourdomain.com TXT "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com; adkim=s; aspf=s"

4. Secret exposure audit

Signal: No API keys appear in frontend code bundles, Git history snapshots you can still access locally show no live secrets committed recently, and production env vars are separated from staging.

Tool or method: I search the repo for key patterns using ripgrep plus secret scanners like Gitleaks or TruffleHog. Then I inspect build artifacts because many founders accidentally expose keys in compiled frontend output.

Fix path: Rotate any exposed key immediately. Move secrets into host-managed environment variables or a secret manager. If a frontend app needs a public token by design, confirm it is truly public-scoped and cannot mutate sensitive data.

5. Auth boundary review

Signal: Users cannot access another user's orders, automations, invoices, or profile by changing an ID in the URL or API request.

Tool or method: I test direct object access manually with browser dev tools and API requests through Postman or curl. This is where weak authorization usually hides in AI-built apps.

Fix path: Enforce authorization server-side on every sensitive route. Never trust client-side role flags alone. If there is an admin panel or internal automation dashboard, I verify least privilege before launch because one bad endpoint can expose customer order data fast.

6. Uptime monitoring on revenue paths

Signal: Alerts fire when homepage uptime drops below 99.9 percent monthly availability target equivalent for the sprint period is "detect within 2 minutes". Checkout/login/webhook failures should page someone immediately.

Tool or method: I set synthetic checks from UptimeRobot or Better Stack against homepage load time under 3 seconds plus authenticated flow probes if needed.

Fix path: Monitor more than just the homepage. Add checks for login page response codes, checkout completion callbacks, and webhook endpoints used by automation tools such as Stripe, Shopify, or Zapier-style integrations. If a webhook fails silently, your automation-heavy business can look live while money stops moving.

Red Flags That Need a Senior Engineer

• You have more than one place managing DNS changes.

That usually means someone will break mail, SSL, or redirects during launch.

• Secrets were ever pasted into Lovable,

Cursor, Bolt, v0, GitHub issues, Slack, or a frontend env file that shipped to production.

• Your checkout,

login, or onboarding flow depends on third-party scripts you do not fully control. That creates both security risk and conversion loss.

• You do not know whether your app has server-side authorization checks on every sensitive endpoint.

If you have to guess, stop shipping.

• You need to launch in under 48 hours but still have unresolved email deliverability,

webhook reliability, or deployment rollback questions. That is exactly how founders end up paying twice: once for recovery, once for lost sales.

DIY Fixes You Can Do Today

1. Confirm your canonical domain

Pick one version: either example.com or www.example.com. Set everything else to redirect there with a single 301 rule. Do not leave both live as equal options unless you enjoy duplicate SEO signals.

2. Check your email sender setup

Go to your email provider dashboard and confirm SPF, DKIM, and DMARC are enabled. Send yourself a password reset, welcome email, and order confirmation. If any land in spam, fix that before ads go live.

3. Rotate anything suspicious

If an old screenshot shows a key, if a teammate pasted credentials into chat, or if you accidentally committed .env files once, rotate them now. A leaked key does not become safe because nobody noticed yet.

4. Turn on basic edge protection

If you use Cloudflare, enable SSL/TLS full strict mode where possible, turn on WAF managed rules, and add rate limiting to login, signup, and contact forms. That cuts bot noise fast without rewriting your app.

5. Create a simple incident checklist

Write down who gets notified if checkout fails, who can roll back deploys, where logs live, and how long you can tolerate downtime. For first-time launches, I want that answer in writing before traffic starts hitting the site.

Where Cyprian Takes Over

This service exists for the cases where DIY stops being efficient and starts becoming risky.

If your scorecard shows failures in domain routing, SSL coverage, email authentication, secret handling， or monitoring，

Here is how I map failures to deliverables:

| Failure area | Launch Ready deliverable | Timeline impact | |---|---|---| | Broken DNS or redirects | DNS cleanup , subdomain setup , redirect rules , canonical host selection | Same day | | Weak SSL setup | Cloudflare config , SSL enforcement , mixed content cleanup guidance | Same day | | Poor deliverability | SPF , DKIM , DMARC records plus verification tests | Same day | | Exposed secrets / messy env vars | Secret audit , env var separation , rotation plan , deployment hardening || First half of sprint | | No monitoring / alerting || Uptime checks , failure alerts , handover checklist || Second half of sprint | | Risky production deploy || Safe deployment review , rollback path , post-launch validation || Final handover |

My recommendation is simple: if you are trying to get to first revenue from the first 100 users inside two days,\

support messages,\ and ad spend wasted on traffic sent into a failing funnel.\n The delivery window matters here because security work expands if it is left open-ended.\nIn practice,\nI use the first few hours to remove launch blockers,\nthen I validate production behavior,\nthen I hand over a checklist so you know what was changed,\nwhat still needs attention,\nand what can safely wait until after launch.\n
