Launch Ready cyber security Checklist for AI-built SaaS app: Ready for support readiness in bootstrapped SaaS?.

What "ready" means for an AI-built SaaS app

For a bootstrapped SaaS, "launch ready" does not mean perfect. It means the app can take real users, real traffic, and real support requests without exposing customer data, breaking email delivery, or creating avoidable downtime.

For this product type, I would define ready as:

• No exposed secrets in the repo, logs, or client bundle.
• Domain, SSL, redirects, and subdomains are correct.
• Email authentication passes with SPF, DKIM, and DMARC.
• Production deploy works from a clean build, not a manual workaround.
• Monitoring alerts you before customers do.
• Basic security controls are in place for auth, sessions, CORS, and rate limits.
• Support can answer "is it up?" and "did the email send?" within minutes.

If any of those fail, you are not support ready. You are still in prototype mode, even if the UI looks finished. For a bootstrapped founder, that usually means lost signups, failed onboarding emails, broken payment flows, or a support inbox full of avoidable issues.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | | --- | --- | --- | --- | | Domain and DNS | Root domain and key subdomains resolve correctly | Users need a stable entry point | Broken links, wrong app version, lost trust | | SSL | HTTPS is valid on all public routes | Prevents browser warnings and data exposure | Checkout drops, login friction | | Redirects | One canonical domain with clean 301 redirects | Avoids duplicate content and mixed URLs | SEO split, confusion, cookie issues | | Secrets handling | Zero exposed secrets in repo or client bundle | Stops credential theft | Account takeover, cloud abuse | | Email auth | SPF, DKIM, DMARC all pass | Improves deliverability and trust | Emails land in spam or fail entirely | | Production deploy | Build deploys from source without manual edits | Makes releases repeatable | Broken releases and hidden drift | | Monitoring | Uptime and error alerts are active | You need early warning before users complain | Slow outage discovery, support load | | Caching/CDN | Static assets cached through Cloudflare/CDN | Reduces load and improves speed | Slow pages, higher infra cost | | Auth controls | Login/session/CORS rules are explicit and tested | Protects user accounts and APIs | Data leakage or auth bypass | | Handover docs | Runbook covers deploys, rollback, contacts, and checks | Support can respond fast under pressure | Founder becomes the only operator |

The Checks I Would Run First

1. Secret exposure check

Signal: I look for API keys in environment files committed to Git history, frontend code using private keys directly, or secrets printed in logs. One exposed Stripe key or database URL is enough to treat this as urgent.

Tool or method: I inspect the repo history, search for common secret patterns, scan build artifacts, and verify that only public-safe values reach the browser. I also check whether any AI-generated code hardcoded credentials during prototyping.

Fix path: Move all sensitive values into server-side environment variables immediately. Rotate any secret that may have been exposed. If a key was ever committed publicly or shared with an AI tool by mistake, I assume it is compromised until proven otherwise.

2. Authentication and session safety

Signal: I test whether a user can access another user's data by changing IDs in URLs or API calls. I also check session expiry behavior, password reset flow integrity, and whether login cookies are marked secure and httpOnly.

Tool or method: Manual API testing plus browser devtools plus a quick review of auth middleware. If the app has role-based access control or team accounts, I test owner vs member permissions separately.

Fix path: Enforce authorization on every sensitive endpoint server-side. Do not trust frontend checks alone. Tighten cookie settings, validate reset tokens properly, and block any route that returns data without verifying ownership.

3. Email deliverability setup

Signal: SPF/DKIM/DMARC do not pass consistently across major inbox providers. New users never receive verification emails or password resets land in spam.

Tool or method: I check DNS records at the registrar or Cloudflare level and send test messages to Gmail and Outlook. I verify alignment between sending domain and envelope domain.

Fix path: Add SPF with only approved senders. Enable DKIM signing from your email provider. Set DMARC to at least `p=none` during verification if you need a safe rollout first.

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

Once mail flow is stable, move toward `p=quarantine` or `p=reject`. For bootstrapped SaaS support readiness today above all else means customers actually receive account emails.

4. Deployment reproducibility

Signal: The app works only when someone manually tweaks environment values on the server or clicks around in a dashboard after deploy. That is fragile and will break on the next release.

Tool or method: I run a clean production build from source using the same pipeline every time. Then I compare local behavior to staging and production for config drift.

Fix path: Put deployment steps into one repeatable process with documented env vars. Remove manual post-deploy edits where possible. Add rollback instructions so one bad release does not become an outage.

5. Cloudflare and edge protection

Signal: The site is public but unprotected against obvious traffic spikes or abusive requests. Static assets are not cached well. SSL exists but redirect rules are messy.

Tool or method: I inspect Cloudflare DNS proxying status, caching headers, page rules or redirect rules, WAF settings if available on your plan level logic-wise even if minimal configuration is used now.

Fix path: Put public web traffic behind Cloudflare where appropriate. Enable caching for static assets only. Confirm origin SSL mode is correct so you do not create loops or broken handshakes.

6. Monitoring and alerting

Signal: Nobody knows about downtime until a user complains on email or social media. There is no uptime check on the homepage or login page.

Tool or method: I set up synthetic uptime checks against critical paths like landing page loading plus signup plus login plus webhook health if relevant. Then I make sure alerts go to email plus Slack plus SMS where needed.

Fix path: Start with simple uptime monitoring at 1-minute intervals for core endpoints. Track error rate and response time trends too. For support readiness I want alerting before p95 latency crosses 500ms on key API routes for sustained periods.

Red Flags That Need a Senior Engineer

If you see any of these signs during your own review, buy help instead of trying to patch it piecemeal:

1. The app has working features but no clear separation between frontend secrets and backend secrets. 2. Users can see data they should not own by editing IDs in URLs. 3. Password reset emails are unreliable across Gmail and Outlook. 4. Deployment requires manual server changes after every push. 5. You cannot explain who gets alerted when the site goes down at 2 am.

These are not cosmetic problems. They create support tickets now and security incidents later.

I would also flag any AI-built codebase that mixes business logic into client components too heavily without guardrails around API access. That pattern often ships fast but becomes expensive when you need to secure it under real traffic.

DIY Fixes You Can Do Today

1. Rotate every secret you have shared with collaborators or pasted into prompts. 2. Remove `.env` files from any public repo history if they were committed. 3. Turn on HTTPS-only redirects at your domain provider or Cloudflare. 4. Test signup emails from two inbox providers: Gmail and Outlook. 5. Write down your current deploy steps exactly as they happen today.

If you can do those five things cleanly without breaking anything else then you already reduced risk meaningfully.

I would also suggest one simple test list:

• Open the app in incognito mode.
• Create a new account.
• Verify email delivery.
• Reset password once.
• Log out then log back in.
• Hit refresh on every major route after deploy.

If any step fails twice in a row then support readiness is still incomplete.

Where Cyprian Takes Over

Here is how checklist failures map to Launch Ready deliverables:

| Failure area | What I fix in Launch Ready | Timeline | | --- | --- | --- | | DNS confusion / wrong domain routing | DNS setup plus redirects plus subdomains cleanup | Hours 1-8 | | Missing SSL / mixed content / browser warnings | Cloudflare configuration plus SSL validation plus canonical HTTPS redirects | Hours 1-8 | | Weak email delivery setup | SPF/DKIM/DMARC records plus sender alignment checks | Hours 6-16 | | Fragile deployment process | Production deployment hardening plus environment variable cleanup + release checklist | Hours 8-24 | | Exposed secrets risk / bad env handling | Secret audit plus rotation guidance plus safer config layout |- Hours 8-24 | | Slow static delivery / poor edge caching |- Cloudflare caching + asset optimization rules |- Hours 12-24 | | No visibility into outages |- Uptime monitoring + alert routing + handover notes |- Hours 18-36 | | Missing handover docs |- Final support-ready checklist with rollback notes |- Hours 36-48 |

My recommendation for bootstrapped SaaS is simple: fix launch safety first before spending more on design polish or extra features.

The reason is business risk management. A prettier product with broken email auth still loses users quickly because onboarding fails at the first step while support volume rises immediately after launch.

What success looks like after the sprint

After Launch Ready is done I want you to be able to say this with confidence:

• The app loads over HTTPS everywhere.
• Signup emails arrive reliably.
• No critical secrets are visible outside server-side config.
• Deployments are repeatable.
• Uptime monitoring tells you when something breaks.
• You have a handover checklist someone else can follow if needed.

For most early-stage SaaS teams that is enough to reduce support chaos dramatically without overspending before product-market fit is proven.

If your current setup feels fragile but close to launch then this is exactly the kind of cleanup sprint I would run first before anything else.
