Launch Ready cyber security Checklist for automation-heavy service business: Ready for security review in marketplace products?.

What "ready" means for Launch Ready

For this product, "ready" does not mean the site looks finished. It means a marketplace reviewer can inspect the business, domain, email, deployment, and basic security posture without finding avoidable risks that delay approval or expose customer data.

If I were self-assessing this service before a security review, I would want all of the following true:

• The primary domain resolves correctly over HTTPS with no mixed content.
• Redirects are intentional and do not create loops or open redirect risks.
• DNS records are clean, documented, and owned by the business.
• SPF, DKIM, and DMARC pass for outbound email.
• No secrets are exposed in code, logs, browser bundles, or public repos.
• Cloudflare is active with WAF and DDoS protection on.
• Production deploys are controlled, repeatable, and reversible.
• Monitoring is live so outages are detected before customers complain.
• Marketplace reviewers can test the product without hitting broken auth, expired certs, or blocked emails.

For an automation-heavy service business, the biggest risk is not one giant breach. It is a pile-up of small failures: broken onboarding emails, weak DNS setup, exposed API keys, and no monitoring. That combination creates support load, failed reviews, wasted ad spend, and a product that looks unsafe even if the app itself works.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | HTTPS everywhere | All pages redirect to HTTPS with valid SSL | Reviewers expect encrypted traffic | Mixed content warnings, trust loss | | DNS ownership | Domain records documented and controlled | Prevents accidental outages | Email loss, site downtime | | Redirect hygiene | One canonical URL path per page | Avoids duplicate content and loops | Broken login links, SEO issues | | SPF/DKIM/DMARC | All pass on outbound mail | Needed for deliverability and trust | Emails land in spam or fail | | Secret handling | Zero exposed secrets in repo or client bundle | Stops account takeover risk | API abuse, billing fraud | | Cloudflare protection | WAF and DDoS enabled with sane rules | Reduces bot noise and attacks | Uptime drops under load | | Production deploy safety | Rollback path exists and is tested | Limits blast radius of bad releases | Long outages after deployment | | Monitoring live | Uptime alerting active with 5 min checks | Detects failures fast enough to act | Silent downtime for hours | | Access control | Least privilege on admin tools and hosting | Limits damage from one compromised account | Full environment compromise | | Logging hygiene | No PII or secrets in logs | Protects customer data during incidents | Compliance problems and leaks |

Measurable threshold I would use: zero exposed secrets, SPF/DKIM/DMARC passing, SSL valid on all public endpoints, and p95 API response under 500ms for core actions.

The Checks I Would Run First

1. Domain and DNS ownership

Signal: the domain points to the right app with no stray A records, stale subdomains, or forgotten verification entries. I also check whether someone still has access to the registrar account.

Tool or method: I inspect DNS records at the registrar and in Cloudflare, then compare them against the live app routes. I also verify who controls renewal alerts and two-factor authentication.

Fix path: remove old records, document every required record, lock registrar access behind MFA, and make sure renewals go to a shared business inbox. If there are multiple environments, separate production from staging with clear subdomains.

2. SSL validity and redirect behavior

Signal: every public endpoint serves a valid certificate and redirects cleanly to one canonical URL. There should be no chains longer than one hop unless there is a very specific reason.

Tool or method: I use browser dev tools plus curl checks against root domain, www subdomain, API subdomain, and any login or webhook endpoints. I look for mixed content errors in the console.

Fix path: force HTTPS at Cloudflare or origin level once only. Remove duplicate redirects in app code if Cloudflare already handles them. Renew certificates automatically instead of relying on manual installs.

3. Email authentication for marketplace trust

Signal: SPF passes once per sending domain, DKIM signs outgoing mail correctly, and DMARC is set to at least quarantine during launch review. If transactional mail matters to onboarding flow, I test actual delivery into Gmail and Outlook.

Tool or method: I use MX lookup tools plus real inbox tests from different providers. I also inspect bounce logs if available.

Fix path: publish correct SPF include rules for each sender only once. Rotate DKIM keys if they were copied from another environment. Start DMARC at `p=quarantine`, then move to `p=reject` after you confirm legitimate mail flow.

A simple baseline looks like this:

v=spf1 include:_spf.google.com include:sendgrid.net -all

That line is only correct if those are truly your senders. If it includes random services you do not use anymore, remove them.

4. Secrets exposure across repo and runtime

Signal: no API keys appear in Git history, frontend bundles, build logs, browser storage dumps, or public env files. This is where automation-heavy businesses get burned because many integrations mean many tokens.

Tool or method: I scan the repo history with secret detection tools and inspect deployed assets in the browser network tab. I also check CI variables and hosting dashboards for overbroad access.

Fix path: rotate anything exposed immediately. Move secrets to server-side env vars only where needed. Split public config from private credentials so client code never receives privileged tokens.

5. Cloudflare hardening

Signal: Cloudflare sits in front of production with WAF enabled enough to block obvious abuse without breaking legitimate traffic. Bot traffic should not be able to hammer login forms or webhook endpoints unchecked.

Tool or method: I review firewall rules, rate limits, cache settings, page rules or transforms where relevant. Then I simulate common abuse patterns like rapid form submissions.

Fix path: turn on DDoS protection by default. Add rate limits for auth endpoints and forms. Cache static assets aggressively but never cache private pages or authenticated responses unless explicitly designed for it.

6. Monitoring plus rollback readiness

Signal: uptime checks exist for homepage plus critical user paths like signup or checkout trigger points. There is also a rollback plan that can restore last known good state inside 15 minutes.

Tool or method: I verify monitoring alerts actually reach a human by testing one failure scenario outside business hours if possible. Then I review deployment history for rollback confidence.

Fix path: add 5 minute uptime checks on key URLs plus alert routing to Slack and email. Keep release notes short but explicit so you know what changed when something breaks. If rollback takes more than 15 minutes manually today that is not ready yet.

Red Flags That Need a Senior Engineer

1. You have more than one place managing redirects. That usually means future breakage when one system overrides another without anyone noticing.

2. Secrets were ever committed to GitHub. Even if you deleted them later they may still be recoverable from history or cached builds.

3. The product depends on multiple third-party automations with shared admin credentials. One compromised token can expose billing data across connected systems.

4. You do not know who owns DNS registrar access. That turns renewal day into an outage risk instead of a routine task.

5. There is no rollback plan for production deploys. If a release breaks auth or email delivery you will spend hours debugging under pressure while customers wait.

If any two of these are true at once, DIY becomes expensive fast because the failure mode is usually downtime plus support tickets plus lost trust from marketplace reviewers.

DIY Fixes You Can Do Today

1. Turn on MFA everywhere. Start with registrar accounts, hosting dashboard(s), email provider(s), GitHub/GitLab/Bitbucket, and Cloudflare.

2. Audit your public pages for mixed content. Open your site in Chrome dev tools and fix any HTTP images/scripts/fonts before submission review.

3. Remove old DNS records you do not need. Stale subdomains often point to abandoned services that create confusion during review scans.

4. Test outbound email from three inboxes. Send signup emails to Gmail, Outlook/Microsoft 365 as well as one non-corporate inbox so you see deliverability issues early.

5. Rotate any key that was shared in chat. Treat Slack screenshots as exposure too if they contain tokens or webhook URLs that can be abused later.

Where Cyprian Takes Over

Here is how checklist failures map directly to Launch Ready deliverables:

| Failure found in audit | Launch Ready deliverable | |---|---| | Broken DNS ownership or stale records | DNS cleanup + subdomain setup | | Bad redirects or mixed content | Redirect configuration + SSL enforcement | | Email failing spam checks | SPF/DKIM/DMARC setup | | Exposed secrets or weak env handling | Secret cleanup + environment variable hardening | | Missing bot protection / noisy traffic | Cloudflare config + DDoS protection | | Unsafe deployment process | Production deployment + rollback-safe handover | | No uptime visibility | Monitoring setup + alert routing | | Unclear admin access model | Access cleanup + handover checklist |

The service scope is built for exactly this kind of rescue work:

• Delivery: 48 hours
• Includes domain setup cleanup
• Includes email authentication
• Includes Cloudflare
• Includes SSL
• Includes caching basics
• Includes DDoS protection
• Includes production deployment
• Includes secrets handling
• Includes uptime monitoring
• Includes handover checklist

My recommendation is simple: if you have already built the product but security review keeps slipping because of infrastructure messiness rather than core product logic then buy the sprint instead of stretching it over weeks yourself.
