Launch Ready cyber security Checklist for automation-heavy service business: Ready for scaling past prototype traffic in internal operations tools?.

What "ready" means for an automation-heavy internal ops tool

For this product, "launch ready" does not mean the app merely loads and the login form works. It means your internal ops tool can handle real staff usage, external automations, and a spike in prototype traffic without exposing customer data, breaking email delivery, or falling over when a webhook retries 20 times.

I would call it ready only if a founder can answer "yes" to all of these:

• Domain routes are correct, redirects are intentional, and subdomains are locked down.
• SSL is valid everywhere, no mixed content exists, and Cloudflare is protecting the edge.
• Secrets are not in code, not in chat logs, and not in client-side bundles.
• Email authentication passes SPF, DKIM, and DMARC so ops alerts do not land in spam.
• Production deploys are repeatable, monitored, and reversible.
• Uptime alerts exist before the first real customer or staff workflow depends on the system.
• The app has no critical auth bypasses, no public admin routes, and no accidental data exposure.
• p95 API latency is under 500ms for core internal actions under expected load.

If any of those fail, you do not have a launch problem. You have a business continuity problem.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | DNS setup | Apex and www resolve correctly; subdomains are intentional | Prevents broken access and bad redirects | Users hit dead links or wrong environments | | SSL everywhere | Valid certs on all public routes; no mixed content | Protects logins and API calls | Browser warnings and blocked requests | | Cloudflare edge | WAF/CDN/DDoS enabled with sane rules | Reduces attack surface during launch | Basic floods or bots degrade service | | Secrets handling | Zero secrets in repo, frontend bundle, or logs | Stops credential leaks | Full account compromise or vendor abuse | | Email auth | SPF, DKIM, DMARC all pass | Keeps alerts and invites deliverable | Internal ops emails land in spam | | Auth controls | No critical auth bypasses; least privilege enforced | Protects sensitive internal workflows | Staff see records they should not access | | Redirects/subdomains | Old URLs redirect cleanly; admin domains isolated | Avoids confusion and phishing risk | Broken links and shadow admin exposure | | Monitoring | Uptime + error alerts active with named owner | Detects failures before users do | Downtime lasts until someone complains | | Deployment safety | Repeatable deploy with rollback path | Limits release risk under pressure | Bad deploy becomes outage | | Caching/performance | Core pages load fast; p95 API under 500ms | Keeps internal users productive | Slow ops tools create support load |

The Checks I Would Run First

1. Public surface inventory

• Signal: I can list every public hostname, route group, webhook endpoint, admin path, and file bucket in under 15 minutes.
• Tool or method: DNS scan, Cloudflare dashboard review, repo search for routes/env vars, browser crawl.
• Fix path: Remove anything that should not be public. Put admin tools behind auth or IP restrictions. Kill orphaned subdomains.

2. Secret exposure sweep

• Signal: No API keys, tokens, private URLs, or service credentials appear in Git history, client bundles, logs, or support screenshots.
• Tool or method: Secret scanning with GitHub secret scanning, TruffleHog, or Gitleaks. Search build artifacts too.
• Fix path: Rotate anything exposed. Move secrets to server-side env vars or a managed secret store. Rebuild after purge.

3. Auth and authorization test

• Signal: A normal user cannot access another user's data by changing IDs or replaying requests.
• Tool or method: Manual role testing with Postman/Insomnia plus browser dev tools. Try ID swapping on records and endpoints.
• Fix path: Enforce authorization on every request server-side. Do not trust frontend role checks. Add tests for horizontal privilege escalation.

4. Email deliverability check

• Signal: SPF passes, DKIM signs messages correctly, DMARC is set to at least quarantine for monitoring stage.
• Tool or method: Send test emails to Gmail/Outlook and inspect headers. Use MXToolbox or similar DNS validation.
• Fix path: Publish correct DNS records. Align From domain with sending provider. Set up bounce handling so failed alerts do not disappear.

5. Edge protection review

• Signal: Cloudflare is proxying traffic where appropriate; rate limits exist on login, webhooks, and sensitive forms.
• Tool or method: Cloudflare dashboard review plus a few safe burst tests from staging or off-hours production windows.
• Fix path: Turn on WAF basics, bot protection where needed, rate limit login/reset endpoints, and block obvious abuse patterns.

6. Release observability check

• Signal: You know when deploys happen, when errors spike, and who gets paged if uptime drops below target.
• Tool or method: Verify uptime monitor setup plus app logs and error tracking such as Sentry or equivalent.
• Fix path: Add one uptime check per critical route plus one alert for elevated 5xx errors. Name an owner before launch.

Red Flags That Need a Senior Engineer

1. Secrets have already leaked once

If keys were committed to GitHub or pasted into client-side code even briefly, I treat that as a rotation-and-audit event. DIY fixes here often miss old tokens still active in third-party systems.

2. Admin access is role-based only in the UI

If the frontend hides buttons but the backend does not enforce permissions on every request, that is not security. A founder can ship this by accident and expose internal records to any logged-in user.

3. Webhooks can trigger destructive actions

If Stripe-like retries or external automation calls can delete data, send emails at scale, or move records without idempotency checks, you will eventually get duplicate actions or silent corruption.

4. There is no rollback plan

If every deploy is manual and nobody knows how to revert within 10 minutes, one bad release can freeze operations for hours. That becomes lost revenue plus support overload very quickly.

5. Email delivery is business-critical but unverified

If password resets, alerts back to staff, approvals across tools like Zapier/Make/n8n flow through email without SPF/DKIM/DMARC validation then you are one DNS mistake away from missed operations.

DIY Fixes You Can Do Today

1. Audit your public domains

Write down every domain and subdomain you own. Remove anything unused from DNS now so there are fewer places to attack later.

2. Rotate obvious secrets

Change any key you shared in Slack/email/screenshots last month. Then move those values into environment variables instead of hardcoding them.

3. Turn on basic Cloudflare protections

Proxy your main app through Cloudflare if it is supported by your stack. Enable HTTPS enforcement and add simple rate limits on login and password reset routes.

4. Check email authentication

Look up your SPF record first because it is usually the fastest fix to validate sending identity:

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

Replace the includes with your actual providers only after confirming who sends mail from your domain.

5. Set one uptime alert now

Even if the rest of monitoring is incomplete today will still be better than tomorrow morning after an outage report from staff. Monitor the homepage plus one authenticated health endpoint if possible.

Where Cyprian Takes Over

• Hours 0-6: Audit domain map DNS records redirects subdomains Cloudflare posture secret exposure paths.
• Hours 6-16: Clean up production deployment environment variables SSL enforcement caching headers DDoS settings.
• Hours 16-28: Validate SPF DKIM DMARC set up monitoring add rollback-safe deployment steps verify error tracking.
• Hours 28-40: Run auth checks webhook safety checks basic abuse testing and fix any exposed admin surfaces.
• Hours 40-48: Final handover checklist docs ownership map alert review and launch signoff.

My recommendation is simple:

• If you have one clean app with minor launch gaps use DIY fixes first.
• If you have multiple subdomains secrets drift unclear ownership missing monitoring or suspicious auth behavior buy the sprint now instead of patching blindly.

The business trade-off is straightforward. A bad launch costs more in downtime support hours lost trust and wasted ad spend than this sprint costs to prevent it.
