Launch Ready cyber security Checklist for automation-heavy service business: Ready for production traffic in bootstrapped SaaS?.

What "ready" means for Launch Ready

For an automation-heavy service business, "ready for production traffic" means a stranger can hit your domain, sign up, get emails, use the product, and not expose your data or break your stack.

I would call it ready only if these are true: DNS is correct, SSL is valid, redirects are clean, email authentication passes SPF, DKIM, and DMARC, secrets are not in the repo or frontend bundle, Cloudflare is protecting the app, deployment is repeatable, monitoring alerts you before customers do, and the first 100 users can complete the core flow without auth bypasses, broken webhooks, or timeout errors.

For bootstrapped SaaS, "ready" is not perfection. It means the app can handle real traffic with no critical security gaps, no exposed credentials, no broken onboarding, and no obvious way for a bot or attacker to abuse your automation spend.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | DNS | Domain resolves correctly in all target regions | Users must reach the right app and email endpoints | Downtime, wrong subdomain routing, failed emails | | SSL | HTTPS is valid on apex and subdomains | Protects login and signup traffic | Browser warnings, blocked forms, trust loss | | Redirects | HTTP to HTTPS and non-canonical domains redirect once only | Prevents duplicate URLs and SEO confusion | Broken login links, loops, weak SEO | | Cloudflare | WAF or basic protection enabled with caching rules reviewed | Reduces bot noise and simple attacks | Higher abuse cost, slow pages, more downtime | | Email auth | SPF, DKIM, DMARC all pass | Improves deliverability for onboarding and alerts | Emails land in spam or fail outright | | Secrets | Zero secrets exposed in repo, logs, or client bundle | Stops account takeover and API abuse | Data leaks, billing loss, legal risk | | Deployment | Production deploy is repeatable from source control | Prevents manual mistakes during release | Drift between environments, broken releases | | Monitoring | Uptime checks plus error alerts are live | You need to know before customers complain | Silent outages and support fire drills | | Access control | Admin routes and APIs require proper authz checks | Prevents unauthorized data access | Customer data exposure and fraud | | Performance baseline | Core page LCP under 2.5s on mobile; p95 API under 500ms for main paths | Slow apps kill conversion and increase support load | Drop-offs at signup and failed automations |

The Checks I Would Run First

1. Domain and redirect path

• Signal: `http://`, `https://`, `www`, apex domain, and key subdomains all resolve to one canonical route with one redirect hop max.
• Tool or method: `curl -I`, browser devtools network tab, Cloudflare dashboard.
• Fix path: Set canonical domain rules first. Then add 301 redirects for every old variant. I would remove any redirect chains longer than one hop because they waste time and create failure points.

2. TLS and certificate coverage

• Signal: No certificate warnings on apex domain or subdomains used for app login, API calls, callbacks, or email links.
• Tool or method: SSL Labs test plus a real browser check in incognito mode.
• Fix path: Issue certificates for all required hostnames. If you use Cloudflare proxying on some records but not others, make that consistent. Mixed setup is where teams usually break production traffic.

3. Secrets exposure audit

• Signal: No API keys in Git history, frontend bundles, environment screenshots, logs, or pasted config files.
• Tool or method: Search repo for common key patterns; run secret scanning; inspect build output; check browser source maps.
• Fix path: Rotate anything exposed immediately. Move secrets to server-side env vars or a managed secret store. Never ship private keys to the client.

4. Email authentication chain

• Signal: SPF passes on sending domain; DKIM signs outbound mail; DMARC is set to at least `p=quarantine` after testing.
• Tool or method: MXToolbox or similar checks plus test sends to Gmail and Outlook.
• Fix path: Add one sender per use case if possible. Keep transactional mail separate from marketing mail. If onboarding emails fail here, your activation rate drops fast.

5. Authz around automation endpoints

• Signal: A user cannot trigger another tenant's workflow by changing IDs in the URL or request body.
• Tool or method: Manual tampering tests in Postman or browser devtools; review server-side authorization logic.
• Fix path: Enforce tenant checks on every sensitive query and mutation. Do not trust client-side role flags. This is one of the most expensive bugs because it becomes a data breach.

6. Monitoring and alerting

• Signal: Uptime checks hit login page plus a protected endpoint; error tracking catches uncaught exceptions; alerts go to Slack or email within minutes.
• Tool or method: UptimeRobot/Better Stack/Pingdom plus Sentry or equivalent.
• Fix path: Add synthetic checks for both public pages and authenticated flows where possible. Alert on error spikes as well as full outages so you catch partial failures that hurt conversions.

SPF: v=spf1 include:_spf.your-sender.com ~all
DKIM: enabled at provider
DMARC: v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com

Red Flags That Need a Senior Engineer

1. You have production secrets inside frontend code or committed `.env` files

• That is not a cleanup task anymore. It means rotation work plus an audit of what may already be exposed.

2. Your app has multiple tenants but authorization is handled mostly in the UI

• If the backend does not enforce access control everywhere, someone can usually reach another customer's data with a simple request edit.

3. Webhooks drive revenue-critical automations

• Payment events, CRM syncs, lead routing, booking confirmations, and AI workflows need signature verification plus idempotency controls.

4. You are using several third-party tools with shared credentials

• The more automation you add through Zapier-like glue code and API tokens spread across tools, the easier it is to lose track of who can do what.

5. You already saw suspicious traffic or failed login attempts

• That usually means bots found you early. I would treat that as a launch blocker until rate limits and protection layers are in place.

DIY Fixes You Can Do Today

1. Turn on Cloudflare proxying for public app routes

• This gives you basic DDoS shielding and edge caching without touching application code.
• Keep admin-only hosts separate if needed so you do not cache sensitive pages by mistake.

2. Rotate any password-like values stored in shared docs

• Search Notion, Slack exports, GitHub issues, screenshots, CSVs with credentials.
• If anyone outside engineering can see them today, assume they are compromised.

3. Verify SPF with one sender only

• Do not stack random includes until you know which service sends each message type.
• Clean sender setup usually improves inbox placement faster than changing copy.

4. Add a status page link to your footer or help page

• This does not fix uptime by itself.
• It reduces support load when something goes wrong because users know where to check first.

5. Test your top 3 flows on mobile over slow network conditions

• Signup should still work on 4G throttling.
• If LCP is above 2.5 seconds on mobile homepages or onboarding pages now,

fix images first before adding more scripts.

Where Cyprian Takes Over

If your checklist fails in more than two security areas at once,

Here is how I map failures to delivery:

| Failure area | What I do in Launch Ready | Timeline | |---|---|---| | DNS confusion / bad redirects | Canonical domain setup, redirect cleanup across apex/www/subdomains | Hours 1-8 | | SSL issues / mixed content | Certificate validation across all live hostnames plus HTTPS enforcement | Hours 1-8 | | Email deliverability problems | SPF/DKIM/DMARC setup plus sender alignment review | Hours 4-12 | | Exposed secrets / weak env handling | Secret cleanup audit plus environment variable hardening and rotation plan | Hours 6-18 | | Cloudflare gaps / abuse risk | WAF basics review, caching rules sanity check, DDoS protection confirmation | Hours 8-20 | | Deployment drift / manual releases | Production deployment validation from source-controlled build steps | Hours 10-24 | | Missing monitoring / no alerts | Uptime monitoring setup plus alert routing and handover checklist | Hours 18-30 | | Handoff risk / founder uncertainty | Final production checklist with "what to watch next" notes for ops handoff | Hours 30-48 |

My recommendation is simple: if launch traffic matters this week,

Launch Ready includes domain setup, email authentication, Cloudflare, SSL, deployment, secrets handling, uptime monitoring, and a handover checklist inside 48 hours. That is cheaper than one bad outage during paid acquisition, and far cheaper than cleaning up a leaked key after customers start using the product.
