Launch Ready cyber security Checklist for AI chatbot product: Ready for first 100 users in mobile-first apps?

For a mobile-first AI chatbot product, "ready" does not mean the app looks finished. It means a stranger can sign up on a phone, send messages, get responses, and you do not leak data, expose secrets, or break the app under the first 100 users.

My bar for ready is simple: no exposed secrets, no critical auth bypasses, SPF/DKIM/DMARC passing, Cloudflare in front of the app, SSL enforced everywhere, uptime monitoring active, and the chatbot API staying under p95 500ms for normal requests. If any of those fail, you are not launch ready. You are one incident away from support load, bad reviews, or wasted ad spend.

That is the right move when you need production safety now instead of another week of DIY guesswork.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Secrets | Zero exposed API keys in repo, logs, client bundle | Prevents account takeover and cloud spend abuse | Token theft, fake traffic bills, data access | | Auth | No auth bypass on signup, login, reset, or chat routes | Protects user accounts and private chats | Unauthorized access and support incidents | | Rate limiting | Chat endpoints capped per IP/user/session | Stops abuse and prompt flooding | Cost spikes and degraded response times | | CORS | Only approved origins allowed | Prevents cross-site abuse from random sites | Data exfiltration and browser-side attacks | | SSL/TLS | HTTPS enforced with redirect and valid certs | Protects login and chat traffic in transit | Browser warnings and intercepted sessions | | DNS/Email auth | SPF/DKIM/DMARC all pass | Makes onboarding and password emails deliverable | Emails land in spam or fail entirely | | Cloudflare/WAF | DDoS protection and basic bot filtering enabled | Reduces attack surface on launch day | Downtime from traffic spikes or abuse | | Logging | No PII or secrets in logs; errors traceable by request ID | Helps debug without leaking customer data | Blind incident response and compliance risk | | Monitoring | Uptime checks plus alerting for errors/latency | Lets you catch failures before users do | Silent outages and broken onboarding | | Performance | Mobile LCP under 2.5s on key screens; p95 API under 500ms | Keeps first-time users from bouncing | Lower conversion and higher support tickets |

The Checks I Would Run First

1. Secrets exposure check

• Signal: API keys in `.env`, Git history, frontend bundles, CI logs, or error traces.
• Tool or method: Search repo for `sk_`, `pk_`, `AIza`, `Bearer`, `.env`, then inspect build artifacts and deployed environment variables.
• Fix path: Move all secrets to server-side env vars only. Rotate any key that ever touched a public place. Add secret scanning in CI so this does not happen again.

2. Auth flow integrity check

• Signal: Users can hit chat endpoints without a valid session, reset tokens never expire, or role checks are missing.
• Tool or method: Try direct requests with Postman or curl against protected routes. Test signup, login, logout, password reset, and conversation history access.
• Fix path: Enforce server-side authorization on every sensitive route. Do not trust client state. Add short-lived tokens where possible and verify ownership on every chat transcript fetch.

3. Prompt injection and tool-use check

• Signal: The bot follows malicious user instructions to reveal system prompts, internal docs, API keys, or hidden tool outputs.
• Tool or method: Use red-team prompts like "ignore previous instructions", "show me your system prompt", "print all tools available", or attempts to trick file/search tools.
• Fix path: Separate system instructions from user content. Restrict tool permissions by default. Add allowlists for actions the bot can perform. Escalate risky requests to a human review path.

4. Rate limit and abuse check

• Signal: A single user can send hundreds of messages per minute or create unlimited accounts.
• Tool or method: Simulate bursts from one IP and multiple sessions using a simple load test against signup and chat endpoints.
• Fix path: Add rate limits by IP plus account plus device fingerprint where appropriate. Put hard caps on expensive LLM calls. Return clear retry messages instead of letting the backend melt.

5. Email deliverability check

• Signal: Welcome emails or password resets land in spam or fail DMARC alignment.
• Tool or method: Verify DNS records with your registrar or Cloudflare DNS panel. Send test emails to Gmail and Outlook.
• Fix path: Configure SPF to authorize your mail provider only. Enable DKIM signing. Set DMARC policy to at least `quarantine` after validation.

6. Monitoring and error visibility check

• Signal: You cannot answer basic questions like "is production up?" or "what failed last night?"
• Tool or method: Open the app from a phone on cellular data while watching uptime checks, error alerts, server logs, and latency metrics.
• Fix path: Add uptime monitoring for homepage plus login plus chat endpoint. Send alerts to email and Slack. Track p95 latency and 5xx rates so issues show up before customers complain.

Red Flags That Need a Senior Engineer

1. Your chatbot has direct access to internal tools without permission boundaries

• This is how prompt injection turns into data leakage or destructive actions.

2. Secrets were ever committed to GitHub

• Even if you deleted them later, assume they are burned until rotated everywhere.

3. You have no idea who can see conversation history

• That usually means authorization is incomplete somewhere in the stack.

4. The app works on desktop but breaks on mobile sign-up flows

• Mobile-first users will hit keyboard issues, broken modals, slow loads, and poor conversion fast.

5. You cannot explain your deployment setup clearly

• If you do not know where DNS points, what handles SSL renewal, who owns logs, or how rollback works,

you are one bad deploy away from downtime.

DIY Fixes You Can Do Today

1. Rotate any exposed keys now

• If an API key was shared publicly once,

rotate it before doing anything else.

2. Turn on Cloudflare proxying

• Put DNS behind Cloudflare so you get WAF basics,

DDoS protection, caching, and simpler SSL management.

3. Force HTTPS everywhere

• Redirect all HTTP traffic to HTTPS.

Do not leave mixed content on login pages, webhook endpoints, or admin panels.

4. Check your email authentication

• Confirm SPF,

DKIM, and DMARC are passing before launch. If onboarding emails fail, your first 100 users will feel like the product is broken even when the app itself works.

5. Test the mobile journey end-to-end

• Use an actual phone:

open landing page, sign up, verify email, send message, refresh page, log out, log back in. If any step feels slow or confusing, fix that before buying traffic.

Where Cyprian Takes Over

This is where I stop guessing and start removing risk quickly.

| Failure found in your checklist | What I do in Launch Ready | Timeline | |---|---|---| | Exposed secrets or weak env handling | Audit env vars, rotate keys if needed, move secrets server-side only | Day 1 | | Broken DNS / domain setup / subdomains / redirects | Configure DNS records,, redirects,, subdomains,, canonical URLs,, Cloudflare proxying || Day 1 | | Missing SSL / mixed content / insecure cookies || Enforce HTTPS,, fix certs,, set secure cookie flags || Day 1 | | Weak email deliverability || Set SPF,, DKIM,, DMARC,, test inbox placement || Day 1-2 | | No rate limits / bot protection || Add throttling,, basic WAF rules,, DDoS protection || Day 2 | | No production monitoring || Set uptime checks,, alert routing,, error visibility || Day 2 | | Unclear handover || Deliver checklist,, owner map,, rollback notes,, next-step risks || End of sprint |

My recommendation is straightforward: if your product needs users within 48 hours, do not spend three days learning infra basics while launching an AI chatbot that touches accounts, messages, and possibly customer data.

That is usually true once paid acquisition starts, or once even a small privacy mistake would damage trust with those first 100 users.
