Launch Ready cyber security Checklist for AI-built SaaS app: Ready for investor demo in founder-led ecommerce?

When I say "ready" for an investor demo, I do not mean "the app works on my laptop." I mean a founder can open the product on a fresh browser, log in without friction, show the core ecommerce workflow, and not worry about exposed secrets, broken email, bad redirects, or a demo-killing outage.

For this specific product type, ready means:

• The app is deployed on production infrastructure with HTTPS enforced.
• Domain, subdomains, and email are configured correctly.
• No critical auth bypasses or exposed API keys exist in code, logs, or frontend bundles.
• SPF, DKIM, and DMARC all pass for outbound email.
• Monitoring is live so you know if the demo breaks before an investor does.
• The site loads fast enough to feel credible. For a demo page, I want LCP under 2.5s and no obvious layout shift.
• The security posture is good enough that I would let a founder screen-share it without crossing my fingers.

If any of those are missing, you are not "launch ready." You are still in prototype territory.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | HTTPS everywhere | All pages force SSL with no mixed content | Protects login and checkout data | Browser warnings, trust loss, session issues | | Domain and redirects | Primary domain resolves cleanly with one canonical redirect path | Prevents duplicate URLs and SEO confusion | Broken links, inconsistent branding | | Auth hardening | No unauthenticated access to private routes or APIs | Stops data exposure during demo | Customer data leak, admin takeover | | Secret handling | Zero secrets in frontend code or public repos | Prevents credential theft | API abuse, billing loss, account compromise | | Email auth | SPF, DKIM, DMARC all passing | Makes signup and password reset emails deliverable | Emails land in spam or fail entirely | | Cloudflare protection | WAF/DDoS protection enabled with sane rules | Reduces attack surface on launch day | Demo downtime from noise or attack traffic | | Logging hygiene | No passwords, tokens, or PII in logs | Limits damage if logs are accessed | Data breach risk and compliance issues | | Rate limits | Login and sensitive endpoints rate limited | Blocks brute force and abuse | Account attacks and runaway costs | | Uptime monitoring | External checks alert within 5 minutes of failure | Lets you react before investors notice | Silent outages during demo window | | Deployment safety | Production deploy uses env vars and rollback plan | Reduces launch mistakes | Broken build, leaked keys, long downtime |

The Checks I Would Run First

1. Public exposure scan

Signal: I look for secrets in the repo, frontend bundle, environment files, and logs. If I find even one live key exposed publicly, that is a stop-the-line issue.

Tool or method: GitHub search, ripgrep across the codebase, bundle inspection in browser devtools, and secret scanning tools like GitHub Advanced Security or TruffleHog.

Fix path: Move all secrets to server-side environment variables immediately. Rotate any exposed credentials the same day. Remove them from history if needed.

2. Authentication boundary test

Signal: I try to access private routes and API endpoints without being logged in. If I can fetch customer records or admin data by changing a URL or request ID, the app is not safe to demo.

Tool or method: Browser incognito session plus Postman or curl against key endpoints.

Fix path: Enforce server-side authorization on every protected route. Do not trust frontend guards alone. Add role checks for admin actions and tenant isolation for ecommerce data.

3. Email deliverability check

Signal: Signup emails, password resets, receipts, or invite emails fail authentication or land in spam. For founder-led ecommerce apps, this kills onboarding fast.

Tool or method: MXToolbox for SPF/DKIM/DMARC validation plus test sends to Gmail and Outlook.

Fix path: Publish correct DNS records for SPF, DKIM, and DMARC. Use a verified sending domain. Make sure From addresses match the authenticated domain.

4. Cloudflare and origin protection check

Signal: The origin server is directly reachable by IP or unprotected hostnames. That means attackers can bypass your edge protections.

Tool or method: DNS inspection plus direct origin probe from outside Cloudflare.

Fix path: Put the app behind Cloudflare proxy mode. Lock down origin firewall rules so only Cloudflare can reach it. Enable WAF basics and DDoS protection.

5. Session and cookie review

Signal: Cookies are missing Secure, HttpOnly, or SameSite flags. Session tokens may be stored in localStorage where scripts can steal them.

Tool or method: Browser application tab plus response header inspection.

Fix path: Set cookies as Secure and HttpOnly where possible. Use SameSite=Lax or Strict depending on flow. Avoid localStorage for sensitive auth tokens unless you have a strong reason and compensating controls.

6. Monitoring and rollback readiness

Signal: There is no uptime monitoring, no error alerting, and no clear rollback path if deployment fails during the investor demo window.

Tool or method: Check UptimeRobot/Better Stack/Pingdom setup plus deployment pipeline review.

Fix path: Add external uptime checks for homepage and login flow. Configure alerts to email and Slack within 5 minutes. Keep one-click rollback ready in your hosting platform.

Here is the kind of simple control I want to see on production cookies:

Set-Cookie: session=abc123; Path=/; HttpOnly; Secure; SameSite=Lax

That one line will not fix everything, but it closes off avoidable session theft paths.

Red Flags That Need a Senior Engineer

1. You have multiple auth systems stitched together. If users can log in with Google OAuth in one place but custom email magic links elsewhere without clear session handling, you are one bug away from account confusion or privilege leakage.

2. Your app uses AI tools with customer data but has no prompt guardrails. If prompts can be manipulated to reveal internal instructions or customer records during an investor demo scenario test will likely expose it fast.

3. Secrets are spread across Lovable/Bolt/Cursor exports. If keys exist in generated code files instead of centralized env management, manual cleanup gets risky fast. One missed key can cost you real money within hours.

4. Production deploys are manual with no rollback. If deployment depends on someone clicking around while nervous before a demo at 9am Monday UK time or 4pm US time zones overlap poorly with support load spikes fast.

5. You cannot explain who owns DNS registrar access. If domain control sits in an old freelancer account or personal email with weak recovery settings that is operational debt waiting to become downtime.

DIY Fixes You Can Do Today

1. Turn on HTTPS enforcement now. Make sure every request redirects to the canonical HTTPS domain only. Remove mixed content warnings by replacing any http assets with https equivalents.

2. Audit your public repo for secrets. Search for API keys, private URLs, webhook signatures, service account JSON files, `.env`, `sk_live`, `pk_`, `Bearer ` strings before pushing anything else live.

3. Verify SPF DKIM DMARC. Use your DNS provider dashboard to confirm all three records exist and pass tests from MXToolbox or your email platform's built-in checker.

4. Lock down admin routes. Even if your UI hides them well enough today add server-side role checks so direct URL access fails with 401 or 403 instead of rendering data.

5. Add uptime monitoring immediately. Create external checks for homepage login page and critical API health endpoint with alerts sent to both email and Slack so failures do not sit unnoticed overnight.

Where Cyprian Takes Over

This is where Launch Ready earns its fee instead of making you spend two days fighting DNS tabs and deploy logs yourself.

• Domain setup
• Email authentication
• Cloudflare configuration
• SSL enforcement
• Redirects and subdomains
• Production deployment
• Environment variable cleanup
• Secret handling review
• Caching setup
• DDoS protection basics
• Uptime monitoring
• Handover checklist

Here is how I map common failures to the sprint:

| Failure found during checklist | Deliverable applied | Typical turnaround | |---|---|---| | Domain misconfigured | DNS fixes + redirect cleanup + subdomain mapping | First 6 hours | | Email failing auth tests | SPF/DKIM/DMARC setup + sender verification | First 8 hours | | Exposed secrets found | Env var migration + secret rotation guidance + cleanup list | First 12 hours | | Origin directly exposed | Cloudflare proxy + firewall restrictions + SSL enforcement | First 12 hours | | No production deployment discipline | Stable deploy + rollback notes + handover checklist | By hour 24 | | No monitoring alerts | Uptime monitoring + alert routing + smoke test targets under watch) | By hour 24 | | Weak caching/performance on public pages | Cache rules + static asset tuning + basic performance pass) || By hour 36 | | Demo risk still unresolved after audit findings) || Final hardening + launch handover by hour 48 |

My rule is simple: if a failure can break trust during an investor demo or expose customer data later that week, I treat it as launch-blocking until fixed.
