Launch Ready cyber security Checklist for automation-heavy service business: Ready for security review in AI tool startups?.

What "ready" means for Launch Ready

For an automation-heavy service business, "ready" does not mean "the site loads." It means a security reviewer can inspect the stack and find clear ownership, no exposed secrets, no broken DNS, no weak email authentication, no open admin paths, and a deployment process that will not leak data or take the business offline.

For an AI tool startup, I would call this ready only if the following are true:

• Domain resolves correctly with HTTPS forced everywhere.
• Cloudflare is in front of the app with DDoS protection on.
• SPF, DKIM, and DMARC all pass for sending domains.
• Production secrets are not in the repo, browser bundle, or logs.
• Admin routes and automation webhooks are protected by auth and allowlists.
• Uptime monitoring is live with alerts going to a real inbox or Slack channel.
• The deployment can be repeated without manual guesswork.
• There are no critical auth bypasses, exposed API keys, or public dashboards.

If any one of those is missing, I would not call it security-review ready. I would call it "launching with avoidable risk."

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | DNS setup | Root domain and subdomains resolve correctly | Users and services need stable routing | Email failure, broken app access, phishing risk | | HTTPS / SSL | All pages force HTTPS with valid certs | Protects logins and customer data | Browser warnings, session theft | | Cloudflare protection | Proxy enabled, WAF/rate limits active | Reduces bot abuse and DDoS impact | Downtime, scraping, brute force | | Email auth | SPF, DKIM, DMARC all pass | Prevents spoofing and deliverability issues | Emails land in spam or get forged | | Secrets handling | Zero secrets in code or client bundle | Stops key leakage and account takeover | Data exposure, billing abuse | | Auth controls | No public admin paths; least privilege enforced | Limits blast radius if a user account is compromised | Unauthorized access to automations | | Webhook security | Signed webhooks or shared secret validation | Protects automation triggers from spoofing | Fake events trigger workflows | | Logging hygiene | No passwords, tokens, or PII in logs | Logs are a common leak path | Compliance issues, support burden | | Monitoring | Uptime checks + alerting configured | Finds outages before customers do | Silent downtime, lost revenue | | Deployment safety | Rollback path and env var checklist exist | Prevents bad deploys from becoming incidents | Extended outages, manual firefighting |

The Checks I Would Run First

1. Domain and DNS integrity

Signal: root domain, www, app subdomain, and any API subdomain all point to the right place with no conflicting records.

Tool or method: I check DNS records directly in Cloudflare or the registrar panel, then verify propagation with `dig` and browser tests.

Fix path: remove stale A/AAAA/CNAME records, set canonical redirects from apex to www or vice versa, and lock down nameserver ownership so nobody on the team can accidentally edit DNS without review.

2. HTTPS enforcement and certificate health

Signal: every route redirects to HTTPS once, no mixed content warnings appear in the browser console.

Tool or method: browser dev tools plus a crawl of key pages. I also test certificate expiry dates and whether any hardcoded `http://` URLs remain in emails or frontend code.

Fix path: enable always-use-HTTPS at Cloudflare or your host, replace insecure asset links, and make sure login/session cookies are marked Secure and HttpOnly where applicable.

3. Secret exposure check

Signal: no API keys in Git history, `.env` files committed by mistake have been removed from history if needed, and nothing sensitive appears in frontend bundles.

Tool or method: I scan the repo for common secret patterns and inspect build artifacts. If there has been a leak already, I rotate keys first before cleaning up code.

Fix path: move secrets into environment variables on the host platform only. Rotate anything that may have been exposed publicly. For example:

SPF_RECORD=v=spf1 include:_spf.google.com ~all
DMARC_RECORD=v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com

4. Email authentication for outbound trust

Signal: SPF passes for your sender provider, DKIM signs messages correctly, and DMARC is aligned.

Tool or method: I use MX lookup tools plus test sends to Gmail and Outlook to confirm authentication headers show "pass."

Fix path: publish correct DNS records for your email provider. Start DMARC at `p=none` if you need visibility first, then move to quarantine or reject after you confirm legitimate mail flow.

5. Webhook and automation boundary review

Signal: every inbound webhook has signature verification or a shared secret check. No workflow can be triggered by an unauthenticated public request.

Tool or method: I trace all Make/Zapier/n8n/custom webhook endpoints from source to destination and try obvious spoofed requests.

Fix path: require signed payloads where available. If not available, use long random secrets plus IP allowlists where practical. Put sensitive workflows behind an authenticated backend endpoint instead of exposing them directly.

6. Deployment rollback readiness

Signal: you can tell me exactly how to deploy again and how to roll back within 10 minutes.

Tool or method: I review the current deployment steps against the actual platform settings. Then I ask one simple question: "If this release breaks login at 6 pm on Friday, what happens next?"

Fix path: document environment variables, build commands, database migration order if relevant, rollback steps, owner contact points, and monitoring alerts before you ship again.

Red Flags That Need a Senior Engineer

1. You have customer-facing automations running off personal API keys from a founder laptop. 2. Your app has an admin route that is protected only by obscurity or a guessed URL. 3. A single environment variable controls production access but nobody knows where it is stored. 4. Your email domain has no DMARC policy yet you send invoices or onboarding emails from it. 5. You cannot answer whether Cloudflare is actually proxying traffic or just managing DNS.

If any of these are true, DIY work usually turns into hidden downtime later. That is when support tickets rise fast and trust drops even faster.

DIY Fixes You Can Do Today

1. Turn on Cloudflare proxying for your main domain if it is not already active. 2. Force HTTPS redirects on every public route. 3. Audit your `.env` files and remove anything sensitive from GitHub immediately. 4. Publish SPF now if you send mail from Google Workspace, Microsoft 365, Resend, Postmark, SendGrid, or similar providers. 5. Add uptime monitoring for homepage load time plus login page availability so you know about outages before customers do.

I would also do one quick browser pass on mobile because many founders miss broken redirects there first. A security review often starts as a trust review when users see inconsistent behavior across devices.

Where Cyprian Takes Over

When Launch Ready finds gaps like these:

• DNS confusion -> I clean up records and set canonical routing.
• SSL problems -> I force HTTPS everywhere and validate certificate health.
• Missing Cloudflare protection -> I put the app behind Cloudflare with DDoS protection on.
• Weak email trust -> I configure SPF/DKIM/DMARC so messages stop landing in spam.
• Secret sprawl -> I move secrets out of code paths into proper environment variables.
• Fragile deployment -> I harden production deployment steps and create a handover checklist.
• No monitoring -> I add uptime checks so failures surface quickly instead of becoming support chaos.

My goal is simple: reduce launch risk fast enough that you can pass security review without guessing what broke last night.

My normal delivery sequence is:

1. Hour 0 to 6: audit domain setup, email auth status, secrets exposure risk. 2. Hour 6 to 18: fix routing issues; enforce HTTPS; confirm Cloudflare settings. 3. Hour 18 to 30: validate production deployment paths; clean env vars; tighten webhook boundaries. 4. Hour 30 to 40: configure monitoring; verify alerts; test rollback assumptions. 5. Hour 40 to 48: final handover checklist plus plain-English notes on what was changed.

If your product depends on automations touching customer data or sending transactional emails at scale around p95 under 500ms response expectations for critical endpoints should be part of the review too. Slow systems are not only annoying; they often mask retries that multiply traffic cost and failure risk.
