Launch Ready cyber security Checklist for automation-heavy service business: Ready for paid acquisition in AI tool startups?.

What "ready" means for Launch Ready

For this product, "ready" does not mean the site looks finished. It means a paid acquisition campaign can send traffic without exposing secrets, breaking email delivery, failing SSL, or creating support chaos.

For an AI tool startup, I would call it ready only if all of these are true:

• Domain and subdomains resolve correctly.
• SSL is valid everywhere, including redirects.
• Cloudflare is in front of the site with sane caching and DDoS protection.
• Production deploys are repeatable and do not depend on one person clicking buttons.
• Environment variables and secrets are not exposed in the repo, logs, or frontend bundle.
• SPF, DKIM, and DMARC pass so outbound email lands in inboxes instead of spam.
• Monitoring alerts you before customers do.
• The onboarding path survives ad traffic, mobile traffic, and broken browser states.

If any of those fail, paid acquisition becomes expensive waste. You do not just lose conversions; you also risk account takeovers, fake signups, downtime during launch spikes, and support load that kills momentum.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | DNS | Root domain and key subdomains resolve in under 60 seconds after changes | Fast propagation reduces launch delays | Campaign links 404 or point to old infrastructure | | SSL | Valid cert on root, www, app, api, and redirect paths | Prevents browser warnings and trust loss | Users bounce and payment pages look unsafe | | Cloudflare | Proxy enabled where needed with correct cache rules | Protects origin and improves speed | Origin gets hit directly during ad spikes | | Redirects | One canonical URL per page with no loops | Preserves SEO and avoids duplicate content | Paid clicks land on broken or split paths | | Email auth | SPF, DKIM, DMARC all passing | Keeps transactional and sales email deliverable | Signups miss verification emails and receipts | | Secrets | Zero exposed secrets in client code or repo history | Prevents account compromise and data leaks | API keys get abused and bills spike | | Deployment | Production deploy is reproducible from a documented process | Reduces human error under pressure | Hotfixes fail during launch day | | Monitoring | Uptime checks plus error alerts are active | Finds outages before customers report them | You learn about downtime from Stripe refunds | | Caching | Static assets cached correctly with versioning | Lowers load time under paid traffic | Slow pages hurt conversion and ad quality | | Access control | Admin tools use least privilege and MFA | Limits blast radius if one account is compromised | One leaked login exposes everything |

The Checks I Would Run First

1. Domain and redirect chain check

Signal: the root domain should resolve cleanly to one canonical destination in one hop. I want no redirect loops, no mixed www/non-www behavior, and no surprise 301 chains that add latency.

Tool or method: `curl -I`, browser dev tools, and a DNS lookup from at least two regions. I also check whether the apex domain points somewhere different from the marketing site by accident.

Fix path: set one canonical host, then enforce it at the edge. If you are using Cloudflare, I would put the redirect rule there instead of scattering it across app code.

2. SSL coverage check

Signal: every public entry point must show a valid certificate with no browser warnings. That includes root domain, www, app subdomain, API subdomain, webhook endpoints if exposed publicly, and any preview URLs that customers might touch.

Tool or method: browser lock icon checks plus SSL Labs. I also test expired cert handling by looking at renewal automation rather than trusting memory.

Fix path: issue certs through Cloudflare or your hosting platform with auto-renewal enabled. If a certificate depends on manual steps every 90 days, that is operational debt waiting to break a launch.

3. Secrets exposure check

Signal: zero secrets should be visible in frontend bundles, Git history snapshots that matter now, logs, or public config files. A single exposed API key can become a bill shock or a data incident within hours.

Tool or method: search the repo for `sk_`, `pk_`, `secret`, `token`, `.env`, and provider-specific key prefixes. I also inspect built assets because some teams accidentally ship env values into client code.

Fix path: move secrets to server-side env vars only, rotate anything already exposed, then add secret scanning in CI. If a key has touched GitHub or been pasted into chat tools, I treat it as compromised until proven otherwise.

4. Email authentication check

Signal: SPF passes for your sending provider, DKIM signs outbound mail correctly, and DMARC is set to at least `p=none` during setup with reporting enabled. For paid acquisition on an AI tool startup, failed email auth means broken verification flows and lost leads.

Tool or method: MXToolbox plus direct test sends to Gmail and Outlook. I verify inbox placement for signup emails, password resets if applicable, receipts if you charge upfront, and founder notifications.

Fix path: configure DNS records exactly as your mail provider specifies. Then move DMARC toward enforcement once alignment is stable.

5. Environment separation check

Signal: production must be isolated from staging and local development. No test Stripe keys in prod flows, no prod webhook URLs in dev apps unless intentionally mirrored for testing.

Tool or method: review environment variable names across deploy targets and compare them against actual runtime behavior. I look for mismatched webhook endpoints because they often cause silent failures after launch.

Fix path: create separate env sets per environment with explicit naming conventions. Then document which services own each secret so nobody guesses during an incident.

6. Monitoring and alerting check

Signal: uptime monitoring exists for homepage load success rate plus critical actions like signup or checkout completion. Error alerts should reach someone within minutes when p95 latency climbs above 500 ms or when failures spike above normal baseline.

Tool or method: synthetic uptime checks from at least two regions plus application error tracking. I want alert routing to email plus Slack or SMS depending on severity.

Fix path: monitor the user journey instead of only pinging `/health`. A healthy server that cannot complete signup is still broken for acquisition.

Red Flags That Need a Senior Engineer

1. You cannot explain where production secrets live. That usually means keys are copied around manually across tools like notes apps, chats, spreadsheets, and CI settings.

2. Your deployment requires someone to remember hidden steps. If release success depends on tribal knowledge instead of a checklisted pipeline, you will break something under ad pressure.

3. Email deliverability has already failed once. One spam-folder incident usually means DNS auth is incomplete or sender reputation is weak enough to hurt conversion again.

4. There are multiple domains pointing at different versions of the product. This creates inconsistent trust signals, duplicate content issues, cookie problems, and support confusion.

5. You are planning to spend on ads before monitoring exists. That is how founders buy traffic faster than they can detect outages.

DIY Fixes You Can Do Today

1. Confirm your canonical domain. Pick either `www` or apex as the primary URL and make everything else redirect there with one hop only.

2. Rotate any secret you have pasted into shared docs or chat. If you are unsure whether it was exposed publicly even once, rotate it now instead of debating probability later.

3. Add SPF,DKIM,and DMARC records. Start with provider instructions exactly as written. Do not improvise record syntax unless you enjoy debugging invisible mail failures.

4. Turn on Cloudflare proxying for public web traffic. This gives you TLS termination options,caching,and DDoS shielding before your first serious ad burst hits origin directly.

5. Set up two alerts today. One uptime alert for homepage availability,and one error alert for signup or checkout failure rate above your normal baseline.

Here is a simple DMARC starting point many founders use while they validate delivery:

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

Use this as a starting line only if your SPF/DKIM setup is already correct enough to test safely.

Where Cyprian Takes Over

If you find even three failures on the scorecard,I would not recommend piecemeal fixes while ads are live.

Here is how failures map to the service deliverables:

• DNS problems -> domain setup,DNS records,sudomain routing,and redirects
• SSL warnings -> Cloudflare configuration plus certificate validation
• Slow asset delivery -> caching rules,image delivery,and edge optimization
• Origin exposure -> DDoS protection,ruleset hardening,and proxy configuration
• Email failures -> SPF,DKIM,and DMARC setup plus validation tests
• Secret sprawl -> environment variables,secrets cleanup,and handover notes
• Broken deploys -> production deployment plus rollback-safe release process
• No visibility -> uptime monitoring,error tracking,and escalation setup

My timeline would be:

• Hour 0 to 8: audit current state,set canonical architecture,and identify blockers.
• Hour 8 to 24: fix DNS/SSL/email/auth basics,secrets handling,and edge protection.
• Hour 24 to 36: deploy production build,caching,routing,and monitoring checks.
• Hour 36 to 48: regression test,handover checklist,written owner map,and launch signoff.

For AI tool startups trying to buy attention quickly,the real cost is not just engineering time,it is wasted ad spend,fewer trials,and avoidable trust damage.
