Launch Ready cyber security Checklist for founder landing page: Ready for support readiness in bootstrapped SaaS?

"Ready" for a bootstrapped SaaS landing page does not mean "the page loads." It means a stranger can land, trust the brand, submit their email or book a demo, and you can support them without exposing customer data, breaking deliverability, or creating a fire drill the first time traffic spikes.

For this product and outcome, I would define ready as: DNS is correct, SSL is enforced, redirects are clean, email authentication passes, no secrets are exposed in the frontend or repo, deployment is repeatable, uptime is monitored, and the support path is visible enough that a founder can answer tickets without guessing. If any of those fail, you are not support-ready. You are just live.

For a bootstrapped SaaS founder, the business risk is simple:

• Lost leads because forms fail or emails land in spam.
• Support load because nobody knows what is deployed where.
• Security exposure because API keys or admin links leak.
• Downtime because there is no monitoring or rollback path.
• Wasted ad spend because paid traffic lands on a page with broken trust signals.

If I were auditing this in one pass, I would aim for:

• Zero exposed secrets.
• SPF, DKIM, and DMARC all passing.
• SSL enforced everywhere.
• No critical auth bypasses.
• LCP under 2.5s on mobile for the landing page.
• Uptime monitoring alerting within 5 minutes.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | DNS setup | Domain resolves correctly with apex and www handled | Visitors must reach the right site every time | Lost traffic, duplicate pages, bad SEO | | SSL enforced | HTTPS only, no mixed content | Trust and security start here | Browser warnings, form drop-off | | Redirects clean | 301s only where needed, no loops | Protects SEO and user flow | Broken links, crawl issues | | Email auth passes | SPF, DKIM, DMARC all pass for sending domain | Support emails must arrive reliably | Spam folder delivery, missed replies | | Secrets hidden | No keys in frontend code or repo history | Prevents account abuse and data leaks | Billing abuse, service compromise | | Deployment repeatable | One-click or scripted deploy with rollback path | Reduces release risk | Manual errors and downtime | | Monitoring active | Uptime alerts plus error logging enabled | You need to know before users do | Silent outages and support chaos | | Caching configured | Static assets cached at edge; HTML strategy intentional | Improves speed and lowers load cost | Slow page loads and higher bounce rate | | DDoS protection on | Cloudflare or equivalent enabled correctly | Protects small teams from noisy attacks | Site becomes unavailable under load | | Handover complete | Admin access list and runbook documented | Support readiness depends on clarity | Founder cannot fix simple incidents |

The Checks I Would Run First

1. DNS and domain control Signal: The apex domain and www version both resolve to the intended landing page with no conflicting records.

Tool or method: I check registrar access, DNS records, and propagation with `dig`, `nslookup`, and Cloudflare dashboard review.

Fix path: Remove stale A/AAAA/CNAME records, set canonical host rules, and make sure only one source of truth exists for DNS. If the domain is split across two providers, I consolidate it before launch.

2. SSL and mixed content Signal: The browser shows a valid certificate on all public pages and there are no insecure asset requests.

Tool or method: I use Chrome DevTools Security tab, SSL Labs test, and a crawl for `http://` assets.

Fix path: Force HTTPS at the edge, update hardcoded asset URLs to HTTPS or relative paths, and set HSTS once everything is stable. If images or scripts still load over HTTP after that change, I treat it as a release blocker.

3. Email deliverability Signal: SPF includes the right sender, DKIM signs outgoing mail, DMARC policy exists with alignment passing.

Tool or method: I test with MXToolbox or similar checks plus actual send tests to Gmail and Outlook.

Fix path: Add SPF records carefully so they do not exceed lookup limits. Then enable DKIM signing in your provider and publish DMARC with at least `p=none` during initial verification.

A minimal example looks like this:

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

If support emails are going to spam today, this usually fixes it faster than changing copy on the page.

4. Secrets exposure Signal: No API keys, private tokens, webhook secrets, or admin credentials appear in frontend bundles, environment files committed to git history, or public logs.

Tool or method: I scan the repo history with secret search tools plus manual review of `.env`, build output, server logs, and browser source maps.

Fix path: Rotate anything exposed immediately. Move secrets into server-side environment variables or hosted secret storage. If a secret has been committed once publicly accessible code should be treated as compromised until rotated.

5. Deployment safety Signal: A deploy can be repeated without manual edits on production servers.

Tool or method: I inspect CI/CD config, hosting settings, build commands, environment variable setup, and rollback ability.

Fix path: Standardize build steps so staging matches production behavior. Add smoke tests after deploy that verify homepage load time under 2.5s on mobile network conditions and confirm forms submit successfully.

6. Monitoring and incident visibility Signal: You get an alert when uptime drops or errors spike within minutes.

Tool or method: I check uptime monitors like UptimeRobot or Better Stack plus error tracking such as Sentry.

Fix path: Set a homepage check every 1 minute from at least 2 regions. Add alerts for downtime over 5 minutes and error spikes above your baseline. Without this you will hear about outages from customers first.

Red Flags That Need a Senior Engineer

1. The landing page uses multiple third-party tools but nobody can say where form submissions go.

• This usually means lost leads during peak traffic or after an integration failure.

2. Secrets were pasted into frontend code "just for now."

• That is how billing abuse happens fast on small teams with no security buffer.

3. The domain has been touched by several builders already.

• Mixed DNS ownership creates broken redirects and email delivery problems that are painful to untangle.

4. There is no rollback plan.

• If a launch breaks checkout links or forms during an ad campaign you lose money immediately while debugging live traffic.

5. The founder cannot explain who gets alerted when the site goes down.

• That means support readiness does not exist yet because nobody owns incident response.

DIY Fixes You Can Do Today

1. Turn on Cloudflare proxying for the main site if it is not already active.

• This gives you basic DDoS protection plus edge caching without rebuilding anything major.

2. Force one canonical domain.

• Pick either `www` or apex as primary and redirect everything else with 301s only. Do not leave both versions indexable.

3. Audit your environment variables.

• Delete anything unused from local files shared in chat tools or copied into frontend code by mistake.

4. Test your sending domain manually.

• Send one email to Gmail and one to Outlook after publishing SPF/DKIM/DMARC so you can verify inbox placement before launch traffic arrives.

5. Add uptime monitoring now.

• Even a simple monitor that checks every minute is better than waiting until a customer says "the site is down."

Where Cyprian Takes Over

This is where Launch Ready becomes worth paying for instead of piecing together fixes over several evenings.

If your checklist failures include DNS confusion, I take over:

• Domain setup
• DNS cleanup
• Redirect rules
• Subdomain mapping

If your failures include trust or deliverability, I take over:

• Cloudflare configuration
• SSL enforcement
• SPF/DKIM/DMARC setup
• Caching rules
• DDoS protection

If your failures include production risk, I take over:

• Production deployment
• Environment variables
• Secret handling
• Uptime monitoring
• Handover checklist

My goal is to get you from "works on my machine" to "safe enough to accept traffic" with clear ownership at handoff.

Here is how I would sequence it:

Typical 48-hour sprint flow: 1. Hour 0 to 6: audit access gaps and map risks. 2. Hour 6 to 18: fix DNS, redirects, SSL, Cloudflare basics. 3. Hour 18 to 30: configure email authentication and secrets handling. 4. Hour 30 to 40: production deployment validation plus smoke tests. 5. Hour 40 to 48: monitoring setup and handover checklist delivery.

The handover matters as much as the fixes. Without it you still own hidden risk later when someone changes copy tools, swaps hosting providers roughly six months from now after ad spend has already started flowing through the page.
