Launch Ready cyber security Checklist for community platform: Ready for handover to a small team in mobile-first apps?.

Launch Ready means the platform can be handed to a small team without creating security debt

For a community platform, "ready" does not mean the app looks finished. It means a small team can own it without guessing where secrets live, how domains are routed, whether email is authenticated, or what happens when traffic spikes or someone tries to abuse sign up flows.

If I were self-assessing this product, I would want all of the following to be true:

• The production domain resolves correctly over HTTPS.
• Admin, staging, and production are separated.
• No secrets are exposed in the repo, client bundle, or logs.
• Email deliverability is working with SPF, DKIM, and DMARC passing.
• Cloudflare is in front of the app with caching and DDoS protection enabled.
• Uptime monitoring exists and alerts reach a real human.
• The handover doc explains who owns DNS, hosting, email, and incident response.
• There are no critical auth bypasses, no public admin panels, and no open write endpoints without rate limits.

For mobile-first apps, this matters more because users tolerate slow desktop sites less on phones. If LCP is above 2.5s on common devices or login breaks on spotty mobile networks, support load climbs fast and trust drops even faster.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | HTTPS everywhere | All production URLs redirect to HTTPS with valid SSL | Prevents interception and browser warnings | Login failures, trust loss, mixed-content errors | | Domain routing | Root domain and key subdomains resolve correctly | Users must reach app, admin, API, and email services | Broken onboarding and support confusion | | Email auth | SPF, DKIM, and DMARC all pass | Stops spoofing and improves inbox placement | Password reset emails land in spam or get rejected | | Secrets handling | Zero exposed secrets in repo or frontend bundle | Protects API keys and database access | Account takeover or data exposure | | Cloudflare protection | WAF/CDN/DDoS enabled with sensible rules | Reduces abuse and absorbs traffic spikes | Outages from bot traffic or simple attacks | | Production deploy | Production build deploys from a known source with rollback path | Avoids random manual changes | Broken releases and impossible recovery | | Monitoring | Uptime checks plus alerting to email/Slack/SMS | You need to know before users complain | Hours of silent downtime | | Rate limiting | Auth and write endpoints have limits | Community apps attract spam and abuse quickly | Credential stuffing and fake signups | | Access control | Admin routes require strong auth and least privilege | Small teams need clear boundaries | Unauthorized content changes or data leaks | | Handover docs | Team knows owners for DNS, hosting, email, logs, secrets | Prevents dependency on one builder forever | Delays during incidents and future launches |

The Checks I Would Run First

1. Check domain ownership and DNS control

Signal: The team can prove who owns the registrar account, DNS provider access, and subdomain records. There should be no mystery about where `app`, `api`, `admin`, or `mail` point.

Tool or method: I would inspect registrar access directly, export DNS records, and verify current propagation with `dig` or a DNS checker.

Fix path: Move ownership into a shared company account. Document every record that matters. If any critical record is unmanaged or duplicated across providers, I would clean it up before launch.

2. Check SSL termination and redirect behavior

Signal: Every public route returns HTTPS only. HTTP should redirect once to HTTPS without loops. No browser mixed-content warnings should appear on login or checkout flows.

Tool or method: I would test with browser dev tools plus `curl -I http://domain.com` and `curl -I https://domain.com`.

Fix path: Install valid certificates through Cloudflare or your host. Force HTTPS at the edge. Remove hardcoded `http://` assets in frontend code or CMS content.

3. Check exposed secrets in codebase and runtime

Signal: No API keys appear in Git history, frontend bundles, logs, analytics payloads, or error traces. Public environment variables should only contain non-sensitive values.

Tool or method: I would scan the repo with secret detection tools like Gitleaks or TruffleHog and inspect built assets for leaked values.

Fix path: Rotate anything exposed immediately. Move secrets into server-side environment variables or managed secret storage. Add pre-commit scanning so this does not happen again.

4. Check email authentication for deliverability

Signal: SPF includes the correct sender services. DKIM signing is enabled. DMARC exists with at least `p=none` during initial setup so reports can be reviewed without breaking mail flow.

Tool or method: I would test with MXToolbox plus actual send tests for password reset emails from production.

Fix path: Correct DNS records at the registrar or DNS host. Align From addresses with approved sending domains. If transactional mail is split across tools like Postmark or SendGrid, document each sender clearly.

Example DMARC starter record:

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

5. Check Cloudflare edge protection

Signal: Cloudflare sits in front of production with proxying enabled where appropriate. WAF rules block obvious abuse patterns. Cache rules do not break authenticated pages.

Tool or method: I would review Cloudflare dashboard settings plus test requests from a fresh network to confirm headers and caching behavior.

Fix path: Turn on DDoS protection defaults first. Add rate limits for sign up/login/reset endpoints if needed. Keep private routes uncached. Make sure origin IPs are not publicly exposed unless required.

6. Check monitoring and incident visibility

Signal: There is uptime monitoring for homepage, login page, API health endpoint if present, plus alert routing to at least two people. A silent failure should not last more than 5 minutes before someone knows about it.

Tool or method: I would set up synthetic checks from an external monitor such as UptimeRobot or Better Stack and confirm alert delivery by forcing a test outage.

Fix path: Create one health endpoint per environment if needed. Set alert thresholds based on user impact rather than vanity metrics alone. Document who responds first when alerts fire after hours.

Red Flags That Need a Senior Engineer

1. You have no idea which account owns the registrar because three contractors touched the setup already.

2. The app has working auth but no rate limiting on login, invite links are public forever now that they were shared in chat once.

3. Secrets were pasted into `.env` files inside the repo history because "it was just staging."

4. Email verification works sometimes but password resets are landing in spam for Gmail users in your beta list.

5. The team wants to hand this off next week but there is no rollback plan if deployment breaks checkout or signup.

DIY Fixes You Can Do Today

1. Confirm who owns your domain registrar login and move it into a company account if it is still personal.

2. Turn on two-factor authentication for hosting, DNS provider, email provider, GitHub/GitLab/Bitbucket, analytics tools, and admin panels.

3. Search your repo for `.env`, API keys prefixed by common patterns like `sk_`, `pk_`, `AIza`, `xoxb`, then rotate anything suspicious immediately.

4. Send a real password reset email to Gmail Outlook iCloud Yahoo accounts and verify SPF/DKIM/DMARC pass in headers.

5. Add one uptime check for homepage plus one login check so you know when production goes dark before users do.

Where Cyprian Takes Over

| Failure found | What I do | Timeline | |---|---|---| | Domain confusion | Clean registrar ownership plus DNS map for root domain and subdomains | Hours 1-6 | | SSL issues | Configure HTTPS redirects plus certificate validation across environments | Hours 1-8 | | Email deliverability problems | Set SPF/DKIM/DMARC plus validate sending service alignment | Hours 4-12 | | Secret exposure risk | Scan repo/runtime then rotate exposed credentials where needed | Hours 6-16 | | Weak edge protection | Configure Cloudflare proxying cache rules WAF basics DDoS settings | Hours 8-18 | | Deployment uncertainty | Push production build verify env vars rollback notes handover steps | Hours 12-24 | | Missing monitoring | Set uptime alerts health checks escalation contacts test notifications end-to-end | Hours 18-30 | | Handover gaps | Deliver checklist owners access map incident notes next-step risks list || Hours 30-48 |

My recommendation is simple: do not hand over a community platform until domain control email auth secret handling edge protection deployment ownership and monitoring are all documented in one place . That reduces launch risk more than any redesign work will .
