Launch Ready cyber security Checklist for founder landing page: Ready for handover to a small team in bootstrapped SaaS?.

What "ready" means for a founder landing page

For a bootstrapped SaaS landing page, "ready" does not mean polished screenshots and a working contact form. It means a small team can take over without breaking domain routing, leaking secrets, losing email deliverability, or waking up to a hacked admin panel.

I would call it ready when the page is live on the correct domain, SSL is valid, redirects are clean, DNS is documented, Cloudflare is configured, form submissions are protected, environment variables are not exposed, monitoring is active, and the handover notes let a non-founder operator make safe changes. If one of those pieces is missing, you do not have handover readiness. You have a fragile demo.

For this specific product type, I use one business test: can a small team change copy, swap images, deploy safely, and keep lead capture working without me in the room? If the answer is no, the page is not ready.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | Domain ownership | Domain registrar access documented and transferable | Prevents lock-in and lost control | Team cannot renew or update DNS | | DNS records | A, CNAME, MX, SPF, DKIM, DMARC all verified | Keeps site and email working | Email lands in spam or site goes offline | | SSL status | HTTPS valid on all public URLs with no mixed content | Protects users and trust | Browser warnings and lower conversions | | Redirects | www/non-www and old URLs resolve with 301s only | Preserves SEO and user flow | Duplicate pages and broken links | | Cloudflare setup | WAF on, DDoS protection on, caching rules documented | Reduces attack surface and load | Higher downtime risk and slower load times | | Secrets handling | Zero secrets in repo or frontend bundle | Stops credential theft | Account takeover or data exposure | | Deployment access | Least-privilege deploy access for small team roles | Limits blast radius | One bad deploy can take down prod | | Monitoring | Uptime alerts active with owner assigned | Shortens time to detect outages | Broken forms can stay broken for hours | | Form security | Anti-spam plus rate limits plus validation in place | Protects lead capture from abuse | Spam flood, cost spikes, bad leads | | Handover docs | Runbook covers DNS, deploys, rollback, contacts | Makes ownership practical | Team hesitates to change anything |

The Checks I Would Run First

1. Domain and DNS control

• Signal: The registrar account is known, two-factor auth is enabled, and DNS records are exported.
• Tool or method: Registrar dashboard review plus `dig` checks for A, CNAME, MX, SPF.
• Fix path: Move ownership into a company-controlled account, document nameservers, and save a DNS export before any launch change.

2. SSL and redirect integrity

• Signal: Every public URL resolves to HTTPS with one canonical version only.
• Tool or method: Browser check plus `curl -I https://...` on root and key paths.
• Fix path: Force 301 redirects from http to https and from non-canonical hostnames to the preferred domain.

3. Secrets exposure

• Signal: No API keys, private tokens, or service credentials appear in code history or client-side bundles.
• Tool or method: Search repo history plus bundle inspection plus secret scanning.
• Fix path: Rotate any exposed credential immediately and move all secrets to server-only environment variables.

4. Email authentication

• Signal: SPF passes, DKIM signs outbound mail, DMARC policy exists and aligns with sending domain.
• Tool or method: MXToolbox or similar checks plus test email header inspection.
• Fix path: Add correct DNS records for your email provider and confirm alignment before sending any launch emails.

5. Form abuse protection

• Signal: Contact forms reject spam bursts without blocking real users.
• Tool or method: Submit repeated test payloads from multiple IPs; check rate limits and honeypot behavior.
• Fix path: Add server-side validation, CAPTCHA only if needed, rate limiting at edge or app layer, and logging for abuse patterns.

6. Monitoring and incident visibility

• Signal: Uptime alerts go to at least two people with a clear response owner.
• Tool or method: Ping monitoring plus synthetic form submission test plus alert delivery test.
• Fix path: Set uptime checks for homepage and lead form endpoint; route alerts to email plus Slack or SMS.

A simple deployment guardrail I like for founder pages:

NEXT_PUBLIC_APP_URL=https://yourdomain.com
API_KEY=server_only_value
SMTP_PASSWORD=server_only_value

If a secret starts with `NEXT_PUBLIC_`, `VITE_`, or any client-exposed prefix by mistake in many stacks like Next.js or Vite-based apps then it is probably already leaked to the browser. That is not a minor issue. That is a production security incident waiting to happen.

Red Flags That Need a Senior Engineer

1. Secrets already shipped in the frontend If an API key was embedded in JavaScript once deployed publicly then assume it is compromised. I would rotate it before doing anything else.

2. No clear domain ownership If the founder does not know who controls registrar login or Cloudflare access then handover is not possible. This turns into renewal failures and emergency access problems later.

3. Email deliverability is untested If you have never checked SPF/DKIM/DMARC passing on real outbound mail then your launch emails may hit spam. For bootstrapped SaaS that means lost leads you paid to acquire.

4. Forms write directly to production without validation If submissions go straight into CRM or database with no sanitization or rate limit then spam will pollute your pipeline fast. It also creates support noise and possible injection risk.

5. No rollback plan If the team cannot describe how to revert a bad deploy in under 10 minutes then they are one mistake away from downtime during launch week.

DIY Fixes You Can Do Today

1. Turn on two-factor authentication everywhere Do this on registrar accounts, Cloudflare, hosting platform, email provider, GitHub, Figma if design files matter for handover too. This removes the easiest takeover path.

2. Export your current DNS records Save them in a text file and share them with the team. If something breaks later you will want the exact before state.

3. Check your site headers Confirm HTTPS only traffic works and that there are no mixed content warnings from images or scripts loaded over HTTP.

4. Scan your repository for secrets Search `.env`, commit history, deployment logs, pasted tokens in README files too. Rotate anything suspicious immediately instead of hoping nobody saw it.

5. Test your forms end-to-end Submit one real inquiry from Gmail and one from Outlook if possible. Then verify that the message arrives reliably and that auto-replies do not get blocked by spam filters.

Where Cyprian Takes Over

If you want handover-ready instead of half-finished DIY work then this is where I step in with Launch Ready.

Service fit: Launch Ready Category: Launch & Deploy

Delivery: 48 hours Hook: Domain, email, Cloudflare, SSL, deployment, secrets, and monitoring in 48 hours

Here is how checklist failures map to deliverables:

| Failure area | What I fix | |---|---| | Domain confusion | Registrar review, ownership cleanup guidance | Broken DNS/email setup | DNS records for site plus SPF/DKIM/DMARC verification | Non-canonical URLs | Redirect map for www/non-www plus old paths | Weak edge security | Cloudflare setup with caching rules and DDoS protection | SSL issues | Certificate validation and forced HTTPS behavior | Exposed secrets | Environment variable cleanup plus secret handling review | Unreliable deployment | Production deployment check plus safe release notes | No monitoring | Uptime monitoring setup with alert routing | Poor handover docs | Handover checklist for small-team ownership

My timeline is simple:

• Hour 0-6: Access review across domain registrar,

Cloudflare, hosting, and email provider.

• Hour 6-18: DNS,

redirects, SSL, and deployment audit.

• Hour 18-30: Secrets scan,

environment variable cleanup, and form security checks.

• Hour 30-40: Monitoring,

alerting, and smoke tests.

• Hour 40-48: Handover checklist,

ownership notes, and final verification pass.

The outcome I aim for is not just "it works". It should be safe enough that a small team can maintain it without creating an outage during their first edits.

What I consider acceptable thresholds

For a founder landing page handing off to a small team in bootstrapped SaaS:

• HTTPS must be enforced everywhere.
• SPF/DKIM/DMARC must pass on outbound mail.
• Zero exposed secrets in frontend code or public repos.
• Homepage should target an LCP under 2.5s on mobile where practical.
• Critical lead capture should respond reliably with no more than one failed submission per 100 test attempts during validation.
• There should be no critical auth bypasses if any admin area exists at all.

If those numbers are off by much then you do not have a stable launch surface yet. You have avoidable risk attached to revenue generation.
