Launch Ready cyber security Checklist for AI-built SaaS app: Ready for production traffic in coach and consultant businesses?.

Launch Ready means your AI-built SaaS can take real traffic without embarrassing you

For coach and consultant businesses, "ready for production traffic" does not mean the app opens in your browser. It means a stranger can land on the domain, sign up, verify email, pay, log in, and use the product without exposing secrets, breaking redirects, or creating support tickets you cannot answer.

My bar is simple: zero exposed secrets, HTTPS everywhere, SPF/DKIM/DMARC passing, no critical auth bypasses, p95 API latency under 500ms for core flows, and a handover that lets you operate the app without guessing. If any one of those is missing, you are not launch ready. You are still in prototype mode.

For coach and consultant businesses specifically, the risk is not just downtime. It is lost leads, broken onboarding after ad spend starts, inbox deliverability problems, and client data exposure that can damage trust fast. A clean launch protects revenue and reputation at the same time.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain and redirects | Apex and www resolve correctly, one canonical URL only | Prevents duplicate content and login confusion | Broken links, SEO issues, user drop-off | | HTTPS and SSL | All pages force HTTPS with valid certs | Protects logins and forms in transit | Browser warnings, blocked signups | | DNS hygiene | Records are correct and minimal | Reduces misroutes and email failures | Site outage or mail delivery issues | | Email authentication | SPF, DKIM, DMARC all pass | Improves inbox placement for onboarding emails | Welcome emails land in spam | | Secrets handling | No secrets in code or logs; env vars used | Stops credential leaks | Account takeover or API abuse | | Auth checks | No critical auth bypasses; role checks enforced | Protects customer data | Unauthorized access to private records | | Rate limiting | Login and form endpoints rate limited | Reduces brute force and spam abuse | Credential stuffing or fake leads | | Cloudflare protection | DDoS protection and caching enabled where safe | Keeps site online under load | Slow site or full outage during spikes | | Monitoring | Uptime alerts and error alerts active | Detects failures before customers do | Silent downtime and delayed response | | Handover readiness | Checklist covers deploy, rollback, access list | Lets founder operate safely post-launch | Confusion, delays, repeated emergency calls |

The Checks I Would Run First

1. Domain resolution and canonical routing

Signal: `domain.com`, `www.domain.com`, staging URLs, and any subdomains all behave consistently. There should be one public entry point for users.

Tool or method: I would check DNS records, test redirects with `curl -I`, and verify the browser lands on one canonical URL with HTTPS enforced.

Fix path: Set a single canonical domain, add 301 redirects from non-canonical variants, remove stale DNS records, and confirm subdomains point only where needed.

2. Secret exposure review

Signal: No API keys, database URLs, webhook secrets, or JWT signing keys appear in source control, build logs, frontend bundles, or public error pages.

Tool or method: I would scan the repo history plus current codebase for common secret patterns and inspect deployed environment variables. I also check if any client-side code contains values that should stay server-side.

Fix path: Move secrets into environment variables or a secret manager immediately. Rotate anything that may have been exposed already. Do not just delete the bad commit and hope nobody saw it.

3. Authentication and authorization test

Signal: A user cannot view another user's coach dashboard data by changing an ID in the URL or request body. Admin-only actions stay admin-only.

Tool or method: I would run manual tampering tests against key endpoints using a proxy like Burp Suite or simple request replay with altered IDs and roles.

Fix path: Enforce server-side authorization on every sensitive endpoint. Never trust frontend role flags alone. Add tests for object-level access control before launch.

4. Email deliverability setup

Signal: SPF passes with one authorized sender list. DKIM signs outbound mail. DMARC is present with at least `p=none` for initial monitoring or stricter if already validated.

Tool or method: I would inspect DNS records and send test messages to Gmail and Outlook to confirm authentication headers pass.

Fix path: Add correct SPF/DKIM/DMARC records at DNS level. Use a single transactional email provider for app emails so onboarding does not depend on a random SMTP setup.

Example DNS policy:

v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com; adkim=s; aspf=s

5. Production deployment safety

Signal: The live environment uses production databases only where intended, migrations are controlled, rollback is possible, and no debug mode is enabled.

Tool or method: I would compare staging versus production env vars line by line and review deployment logs from the last release.

Fix path: Separate staging from production credentials completely. Add a release checklist that confirms migration order, backup status before deploys, and rollback steps if errors spike after release.

6. Monitoring and incident visibility

Signal: You know when the site goes down within minutes, not days. Core paths like signup, login, checkout, webhook handling, and email sending have alerts attached.

Tool or method: I would verify uptime checks from an external monitor plus application error tracking with alert thresholds tied to real user impact.

Fix path: Turn on uptime monitoring for homepage and key APIs. Add error tracking with alerts on 5xx spikes, failed jobs, payment errors if relevant,and auth failures above normal baselines.

Red Flags That Need a Senior Engineer

• You cannot tell me where secrets live right now.
• Your app has worked only in local development but never under production-like traffic.
• Email onboarding is unreliable because SPF/DKIM/DMARC was never set up.
• Users share data across accounts when you change IDs in URLs.
• You have no rollback plan if deployment breaks signups during launch week.

If any of these are true, DIY becomes expensive quickly. The real cost is not my fee; it is lost leads from broken funnels, support hours wasted debugging live issues, ad spend burned on a broken checkout,and customer trust damaged by avoidable security mistakes.

DIY Fixes You Can Do Today

1. Inventory every secret

List your database URL, API keys, OAuth client secrets, webhook signing keys,and email provider credentials. If any of them are in GitHub files or pasted into frontend code,move them out now.

2. Force HTTPS everywhere

Turn on SSL at the host level，redirect all HTTP traffic to HTTPS，and make sure cookies are marked secure in production. This protects login sessions from interception.

3. Check your DNS records

Confirm there is one canonical domain，clean up old A/CNAME records，and verify your MX records match your email provider instructions exactly。Bad DNS causes both site outages and missing emails。

4. Test email delivery manually

Send welcome emails to Gmail、Outlook、and iCloud addresses。If they hit spam，fix SPF/DKIM/DMARC before launch instead of after customers complain。

5. Try basic abuse tests

Submit forms quickly several times，attempt login brute force behavior，and create two accounts to see whether one can access the other's private data。If rate limits or authorization fail，stop launch until fixed。

Where Cyprian Takes Over

When I run Launch Ready，I am not polishing pixels first。I am closing the security gaps that block real traffic from being safe。

Here is how the failures map to the service:

| Failure found during checklist | Deliverable I handle | Typical timing | |---|---|---| | Domain mismatch / bad redirects | DNS cleanup，redirect rules，subdomain mapping | Hours 1-8 | | Missing SSL / insecure cookies | Cloudflare setup，SSL enforcement，secure session config | Hours 1-8 | | Email delivery problems | SPF/DKIM/DMARC setup，transactional sender config | Hours 4-16 | | Exposed secrets / weak env handling | Environment variable cleanup，secret rotation guidance ,deployment hardening | Hours 4-20 | | Broken production deploy flow | Production deployment fix，rollback notes ,handover checklist updates | Hours 8-32 | | No monitoring / silent failure risk | Uptime monitoring，alerting setup ,health check configuration | Hours 16-36 | | Missing handover docs / access confusion | Handover checklist with owner list ,credentials map ,launch notes |\nHours 32-48 |
