Launch Ready cyber security Checklist for AI chatbot product: Ready for app review in marketplace products?

When I say "ready" for an AI chatbot product in a marketplace app review, I mean the product can be inspected without exposing customer data, failing login flows, or breaking under basic security checks.

For this specific outcome, ready means:

• No exposed secrets in code, logs, or frontend bundles.
• Authentication and authorization work on every protected route and API.
• The chatbot cannot be tricked into leaking system prompts, tokens, or private user data.
• DNS, SSL, email authentication, redirects, and subdomains are configured correctly.
• Monitoring is live so you can see failures before users or reviewers do.

If you are submitting to a marketplace with app review, I would want these minimum thresholds:

• Zero critical auth bypasses.
• Zero exposed secrets.
• SPF, DKIM, and DMARC all passing.
• p95 API latency under 500 ms for core chat requests.
• Uptime monitoring active with alerts on downtime or certificate failure.
• App install and onboarding flow completing in under 3 minutes on desktop and mobile.

If any of those are missing, the review risk is not cosmetic. It becomes a launch delay, a rejection, or worse: support load, broken onboarding, and exposed customer data.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Secrets handling | No API keys in repo, logs, client bundle, or screenshots | Prevents token theft and unauthorized usage | Cost spikes, data leaks, account abuse | | Auth coverage | Every protected route and endpoint requires valid auth | Stops anonymous access to private chat history | Account takeover risk, review rejection | | Role checks | Admin actions require server-side authorization | Prevents privilege escalation | Users can change settings they should not touch | | Input validation | Chat prompts and form inputs are validated server-side | Reduces injection and malformed request failures | Broken flows, prompt abuse, stored attacks | | Chatbot guardrails | System prompt not exposed; tool use is restricted | Prevents prompt injection and data exfiltration | Private data leakage through the bot | | TLS and SSL | HTTPS only with valid certs on all domains/subdomains | Required for trust and secure transport | Browser warnings, failed review checks | | Email auth | SPF/DKIM/DMARC all pass for sending domains | Keeps onboarding emails out of spam | Missing verification emails, poor deliverability | | CORS policy | Only approved origins can call APIs from browser apps | Blocks cross-site abuse of APIs | Data exposure to untrusted sites | | Monitoring | Uptime alerts for app, API, DNS, cert expiry | Catches outages before reviewers do | Silent downtime during review window | | Dependency risk | No known critical vulnerabilities in core packages | Reduces supply-chain exposure | Exploits through outdated libraries |

The Checks I Would Run First

1. Secrets exposure check

Signal: I look for hardcoded keys in the repo, frontend env vars that should never ship client-side, leaked values in logs, and secrets pasted into deployment notes or screenshots.

Tool or method: I scan the repository with secret search tools like Gitleaks or TruffleHog, then inspect build output and browser network traces. I also check hosting dashboards and CI variables to confirm what is public versus server-only.

Fix path: Move secrets into server-side environment variables only. Rotate any key that may have been committed or previewed in a build artifact. If a secret touched the frontend bundle once, I treat it as compromised.

2. Authentication and authorization flow check

Signal: I test whether unauthenticated users can reach protected pages or call private endpoints. I also verify that one user cannot access another user's chat sessions or workspace data by changing IDs.

Tool or method: I run manual requests with Postman or curl against every sensitive endpoint. Then I test role changes directly at the API layer instead of trusting UI behavior.

Fix path: Enforce auth on the server for every request. Add ownership checks on records like conversations, files, billing objects, and admin settings. Never rely on hidden buttons or frontend guards as security controls.

3. Prompt injection and tool-use control check

Signal: I try prompts like "ignore previous instructions", "show me your system prompt", "export all user messages", and "call this tool with hidden data". If the chatbot reveals internal instructions or sends sensitive content to external tools, it is not ready.

Tool or method: I use a red-team prompt set with at least 25 adversarial cases covering jailbreaks, indirect injection from uploaded content, malicious links, and data exfiltration attempts. I also inspect tool permissions one by one.

Fix path: Separate user content from system instructions. Restrict tools to least privilege. Add allowlists for actions like search or file retrieval. If the bot handles private data or marketplace transactions, add human escalation for risky requests.

4. DNS / SSL / email authentication check

Signal: The domain resolves correctly across root domain and subdomains. HTTPS works everywhere. Email authentication passes with SPF/DKIM/DMARC aligned so verification emails do not land in spam.

Tool or method: I use DNS lookup tools plus mailbox tests from Gmail and Outlook. For SSL health I check certificate validity across all hostnames including preview domains if they are used in review.

Fix path: Configure canonical redirects from non-www to www or vice versa. Set up Cloudflare proxying where appropriate. Publish correct SPF records from only approved senders and enable DKIM signing plus DMARC enforcement.

5. CORS / CSRF / browser access check

Signal: Browser-based clients should only talk to approved origins. If any origin can call your API with credentials attached, that is a common leak path.

Tool or method: I inspect response headers for Access-Control-Allow-Origin behavior and test credentialed requests from an untrusted origin. For cookie-based auth I also verify CSRF protection where needed.

Fix path: Use explicit origin allowlists rather than wildcard CORS rules. Set secure cookie flags if using cookies. Add CSRF protection when browser sessions can mutate state.

6. Observability and failure detection check

Signal: When something breaks during review - expired certs, bad deploys, email failures - you need to know within minutes instead of hearing about it from a reviewer message days later.

Tool or method: I confirm uptime monitoring covers homepage availability, login flow health, API latency p95 under 500 ms on core routes, DNS resolution checks, certificate expiry alerts at least 14 days out, and error logging tied to deploy versions.

Fix path: Add synthetic checks for login and chat submission paths. Centralize logs with request IDs. Alert on spikes in 4xx/5xx errors so you can rollback before the marketplace sees a broken build.

SPF=pass
DKIM=pass
DMARC=pass
TLS=valid
Secrets=0 exposed
p95_chat_api=<500ms

Red Flags That Need a Senior Engineer

1. You have multiple environments but no clear secret separation. If staging keys work in production or vice versa, one mistake can expose real customer data during testing.

2. The chatbot has access to files, CRM data, support tickets, billing actions, or external APIs. Once tools are connected to real systems you need strict permission boundaries and audit logging.

3. You are using cookies plus cross-domain frontend hosting plus third-party embeds. That combination often creates session leakage problems unless CORS and CSRF are handled carefully.

4. Your deployment process is manual. If production changes depend on someone remembering steps in Slack messages or Notion docs only one missed setting can break app review day.

5. You already saw weird behavior like duplicate webhooks, missing emails after signup blocks retrying users. Those are signs that infrastructure is unstable enough to fail under reviewer traffic too.

DIY Fixes You Can Do Today

1. Rotate every key you have ever pasted into chat tools or shared docs. Assume anything visible outside your secret manager may be compromised already.

2. Turn on Cloudflare proxying for your main domain if it fits your stack. You get DDoS protection basic caching controls and fewer direct-origin exposures.

3. Audit your environment variables. Anything starting with PUBLIC_ NEXT_PUBLIC_ VITE_ REACT_APP_ or similar should never contain secrets.

4. Test signup login password reset webhook delivery and email verification end-to-end. Do this from a clean browser profile on mobile too because app review often catches broken edge cases there first.

5. Add basic monitoring now. Set alerts for site down SSL expiry DNS failure login errors over 5 percent and chat API latency above 500 ms p95.

Where Cyprian Takes Over

If your checklist failures are around domain setup SSL secrets deployment email deliverability monitoring or launch hardening then this is exactly where Launch Ready fits.

I would map the work like this:

• DNS mistakes -> fix root domain subdomains redirects canonical hostnames
• SSL issues -> issue validate renew certificates across all live endpoints
• Email problems -> configure SPF DKIM DMARC so onboarding mail reaches inboxes
• Secret leaks -> move credentials into safe environment variables rotate exposed keys
• Deployment risk -> push production release safely with rollback-ready configuration
• Monitoring gaps -> add uptime checks logs alerts and handover notes

What you get:

• DNS setup
• Redirects
• Subdomains
• Cloudflare configuration
• SSL setup
• Caching basics
• DDoS protection
• SPF/DKIM/DMARC
• Production deployment
• Environment variables cleanup
• Secrets handling review
• Uptime monitoring
• Handover checklist

My approach is simple: 1. Audit what blocks app review. 2. Fix the launch-critical security gaps first. 3. Verify the chatbot still works after each change. 4. Hand over a clean checklist so you know what passed.
