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

What "ready" means for Launch Ready

For an automation-heavy service business, "launch ready" means a stranger can land on the site, trust the brand, submit a form, get a response, and your stack does not expose secrets, break email delivery, or fall over under normal traffic.

For this product and outcome, I would define ready as:

• Domain resolves correctly with www and non-www redirects handled.
• SSL is valid everywhere, with no mixed content.
• Cloudflare is in front of the site with basic DDoS protection on.
• SPF, DKIM, and DMARC all pass for outbound email.
• Production deployment uses environment variables only, with zero hardcoded secrets.
• Monitoring is active for uptime and basic error visibility.
• Core pages load fast enough to support ads and search traffic, with LCP under 2.5s on mobile.
• There are no critical auth bypasses, exposed admin paths, or public API keys.

If any of those are missing, you are not launch ready. You are in "looks live but will create support load" territory.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | DNS setup | Root domain and www resolve correctly; no stale records | Users and email providers need a clean path to your app | Site outage, wrong destination, broken subdomains | | Redirects | 301 redirects are consistent for www/non-www and http/https | Prevents duplicate content and trust issues | SEO dilution, login confusion, mixed routing | | SSL | Valid cert on all public endpoints; no browser warnings | Trust and data protection start here | Drop in conversions, blocked forms, support tickets | | Cloudflare | Proxy enabled with sane caching and DDoS settings | Shields the app from basic abuse and load spikes | Slowdowns, origin exposure, avoidable downtime | | Email auth | SPF, DKIM, DMARC all pass | Protects deliverability and brand reputation | Emails go to spam or get rejected | | Secrets handling | No secrets in code or client bundle; env vars only | Prevents credential leaks and account takeover | Exposed APIs, billing abuse, data access | | Deployment safety | Production build passes; rollback path exists | Launches fail when deploys are fragile | Broken release, emergency hotfixes | | Monitoring | Uptime checks plus error alerts active | You need to know before customers do | Silent outages, delayed response | | Performance baseline | LCP under 2.5s on mobile for key pages | Speed affects conversion and ad efficiency | Lower signups, higher bounce rate | | Handover docs | Owner knows DNS provider, deploy flow, secrets list location | Prevents tribal knowledge risk after launch | Dependency on one person; slow recovery |

The Checks I Would Run First

1. Domain resolution and redirect integrity

Signal: I check whether the root domain, www subdomain, and any app or api subdomains point where they should. I also verify that http redirects to https with one clean 301 hop.

Tool or method: `dig`, browser checks, Cloudflare DNS panel, and a redirect crawler like Screaming Frog or simple `curl -I`.

Fix path: Remove stale A or CNAME records. Force one canonical host name. If the app lives behind Cloudflare or a host like Vercel or Render, make sure the proxy target matches the deployment target exactly.

2. Email authentication for transactional deliverability

Signal: I send a test message from your domain and inspect SPF/DKIM/DMARC results in Gmail headers. If alignment fails even once, I treat it as a launch blocker.

Tool or method: MXToolbox checks plus Gmail "Show original" header inspection.

Fix path: Publish one SPF record only. Add DKIM signing at the email provider level. Set DMARC to at least `p=none` for initial monitoring if you are not ready to enforce yet.

A minimal example looks like this:

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

The exact value depends on your provider list. The point is not the string itself. The point is that one bad record can break onboarding emails and password resets.

3. Secret exposure review

Signal: I look for API keys in frontend bundles, Git history, `.env` files committed by accident, exposed admin tokens in logs, and public repository leaks.

Tool or method: GitHub secret scanning, `git log`, browser dev tools network tab, environment variable review in the host dashboard.

Fix path: Rotate anything exposed immediately. Move all secrets server-side. Remove them from client code. If a secret was shipped publicly once already, assume it is compromised.

4. Production deployment hygiene

Signal: I verify that production builds run from clean environment variables and that there is a rollback path if the release fails.

Tool or method: CI logs, host deployment history, smoke test after deploy.

Fix path: Add a staging-to-production promotion step if you have time. If not, at minimum create a release checklist with build success criteria and rollback instructions before touching production again.

5. Cloudflare edge protection

Signal: I confirm Cloudflare sits in front of the origin where appropriate and that basic protections are enabled without breaking legitimate traffic.

Tool or method: Cloudflare dashboard review plus origin IP check from DNS history.

Fix path: Turn on proxying for public web traffic. Add WAF rules only where they will not block forms or login endpoints. Cache static assets aggressively but never cache authenticated responses blindly.

6. Monitoring coverage

Signal: I need at least one uptime monitor for the homepage plus one alert route for application errors or failed deployments.

Tool or method: UptimeRobot or Better Stack for uptime; Sentry or equivalent for errors; test alert delivery by forcing a failure.

Fix path: Set alerts to email plus Slack if possible. Monitor both availability and error rate. If your p95 API latency exceeds 500ms during normal use after launch week one needs investigation before paid traffic scales up.

Red Flags That Need a Senior Engineer

1. You have multiple email providers touching the same domain. This often creates SPF failures that are hard to debug without experience.

2. Your app stores tokens in local storage with no clear auth strategy. That increases session theft risk if there is any XSS issue later.

3. You copied environment variables into frontend code to "make it work." That is usually how API keys end up public within hours of launch.

4. You have custom redirects scattered across hosting settings and app code. One bad redirect loop can kill checkout flows or sign-in flows across devices.

5. You do not know what happens when the deploy fails at 9 pm. If there is no rollback plan or ownership model, launch day becomes incident day.

DIY Fixes You Can Do Today

1. Run every public URL through an incognito browser window. Check for SSL warnings,, broken images,, mixed content,, and incorrect canonical hosts.

2. Search your repo for secrets right now. Look for `sk_`, `api_key`, `secret`, private tokens,, `.env`, and pasted credentials in README files.

3. Test your email deliverability manually. Send onboarding mail,, password reset mail,, and contact form notifications to Gmail,, Outlook,, and iCloud addresses.

4. Verify your DNS provider has only one source of truth. Remove old records from previous hosts so you do not accidentally send users to dead infrastructure later.

5. Turn on basic monitoring before traffic starts. Even one uptime alert is better than learning about downtime from a customer screenshot at midnight.

Where Cyprian Takes Over

If you want this done fast without guessing your way through security basics,, this is where I take over:

• DNS cleanup,, redirects,, subdomains,, SSL setup
• Delivery window: first 8 hours
• Outcome: stable domain routing with no broken hostnames

• Cloudflare configuration,, caching,, DDoS protection
• Delivery window: hours 8 to 16
• Outcome: edge protection without breaking forms,, auth,, or dynamic pages

• SPF,, DKIM,, DMARC implementation
• Delivery window: hours 8 to 20
• Outcome: transactional mail passes authentication checks so onboarding works reliably

• Production deployment,, environment variables,, secret handling
• Delivery window: hours 12 to 28
• Outcome: no exposed credentials,, cleaner release process,, safer handoff

• Monitoring setup,, uptime checks,, alert routing
• Delivery window: hours 20 to 36
• Outcome: you know about outages before users flood support

• Handover checklist
• Delivery window: hours 36 to 48
• Outcome: you get exact ownership notes for DNS,, deploys,, secrets,, monitoring,,,and next steps
