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

"Ready" for this kind of product does not mean "the site loads and the forms work." It means a bootstrapped SaaS can accept traffic, collect leads, send email, deploy safely, and survive common abuse without exposing customer data or breaking the launch.

For me, launch ready means all of this is true at once:

• Domain points to the right app and every old URL either redirects cleanly or returns a controlled 404.
• Email is authenticated with SPF, DKIM, and DMARC passing.
• Cloudflare is in front of the app, SSL is enforced, and obvious attack traffic is blocked.
• No secrets are hardcoded in the repo, build logs, or frontend bundle.
• Production deploys are repeatable, monitored, and reversible.
• Uptime alerts exist before launch, not after the first outage.
• The core user journey works on mobile and desktop without broken auth, broken automations, or exposed admin paths.

If any one of those fails, you do not have a launch. You have a liability with a landing page.

Quick Scorecard

| Check | Pass criteria | Why it matters | What breaks if it fails | |---|---|---|---| | DNS points correctly | Root, www, and subdomains resolve to intended targets | Prevents traffic loss and phishing risk | Users hit stale apps or attacker-controlled records | | SSL enforced | HTTPS only, valid certs, no mixed content | Protects logins and forms in transit | Browser warnings, failed trust, dropped conversions | | SPF/DKIM/DMARC pass | All three pass on test mail | Keeps transactional mail out of spam | Password resets and lead emails fail | | Secrets removed from code | Zero exposed API keys in repo or frontend bundle | Stops account takeover and billing abuse | Public key leaks, vendor abuse, incident response | | Cloudflare active | WAF/CDN/DDoS protection enabled | Reduces attack surface and improves resilience | Bot traffic spikes cause downtime | | Redirects are mapped | Old URLs 301 to correct destinations | Preserves SEO and user flow | Broken links and lost signups | | Environment variables set | Prod values separate from dev/staging | Prevents accidental dev data exposure | Test data leaks into production | | Monitoring live | Uptime alert fires within 2 minutes | Detects outage before customers do | You find outages from users first | | Auth boundaries tested | No critical auth bypasses or IDOR paths | Protects customer records and admin tools | Data exposure across tenants/users | | Deployment is reversible | Rollback path exists and has been tested once | Limits blast radius during release issues | A bad deploy becomes hours of downtime |

A practical threshold I use: zero exposed secrets, SPF/DKIM/DMARC passing on test sends, p95 API latency under 500ms for the main app path, and no critical auth bypasses in a basic manual review.

The Checks I Would Run First

1. Domain and redirect integrity Signal: I check whether the root domain, www version, login subdomain, app subdomain, and any legacy URLs all land where they should. I also look for redirect loops, chained redirects, and mixed http/https behavior.

Tool or method: `curl -I`, browser inspection, Cloudflare DNS panel, and a simple URL map spreadsheet. I test both apex and subdomains from a clean browser session.

Fix path: I remove conflicting DNS records first, then set one canonical host strategy. If there are old marketing pages or moved routes, I create 301 redirects instead of letting them die as broken links.

2. Email authentication Signal: Transactional email lands in inboxes instead of spam. I verify SPF includes the right sender, DKIM signs messages correctly, and DMARC is at least set to `p=none` before tightening later.

Tool or method: MXToolbox-style checks plus real test sends to Gmail and Outlook. I inspect message headers to confirm alignment.

Fix path: I add or correct DNS records for SPF/DKIM/DMARC. If multiple vendors send mail - like Resend plus Google Workspace plus an automation tool - I consolidate sending paths so you do not create an authentication mess.

3. Secret exposure review Signal: No API keys appear in Git history, frontend code bundles, deployment logs, or environment screenshots. This is non-negotiable for automation-heavy services because they usually connect to payment APIs, email APIs, databases, CRMs, webhooks, and AI tools.

Tool or method: Repo scan with secret detection tools plus a manual grep for common key patterns. I also inspect build artifacts because many founders hide secrets in client-side config by mistake.

Fix path: Rotate anything exposed immediately. Move secrets to server-side environment variables or managed secret storage. If a secret was ever committed publicly, I treat it as compromised even if "nobody saw it."

4. Cloudflare security posture Signal: Cloudflare sits in front of the app with SSL/TLS enforced, DDoS protection on by default where possible, caching configured carefully for static assets only at first time launch.

Tool or method: Cloudflare dashboard review plus request tracing from browser devtools. I check whether origin IP is hidden where practical and whether WAF rules are blocking obvious junk traffic.

Fix path: Turn on full HTTPS mode only when origin certs are valid. Add rate limiting on login/contact endpoints if the platform supports it. Do not cache authenticated pages unless you know exactly what you are doing.

5. Production environment separation Signal: Production uses production database credentials, production webhook endpoints only where intended ,and no staging/test flags leak into live traffic.

Tool or method: Review `.env`, deployment config ,and runtime logs. Then trigger one non-destructive production action end-to-end such as signup or password reset.

Fix path: Split dev/staging/prod variables clearly. Remove shared credentials between environments. If one environment can write to another environment's database or queues ,that is a launch blocker.

6. Monitoring and incident visibility Signal: Uptime monitoring exists before launch ,and alerts go to at least two channels such as email plus Slack/SMS .I also want basic error logging so failures are diagnosable without guesswork.

Tool or method: Synthetic uptime check against homepage ,login ,and core API endpoint .I verify alert delivery by forcing one safe failure during setup .

Fix path: Add monitoring with a 1-minute check interval if your budget allows it ,or at minimum 5 minutes .Set alert routing so one missed notification does not hide an outage .

SPF example:
v=spf1 include:_spf.google.com include:_spf.resend.com -all

That line is only useful if it matches your actual senders .If it does not ,email deliverability gets worse instead of better .

Red Flags That Need a Senior Engineer

1 . You cannot tell me where every secret lives . If API keys exist in multiple tools ,old repos ,or copied notes ,you need cleanup plus rotation .This is how small teams get billed for abuse they did not cause .

2 . Your product uses several automations that call each other . When webhooks trigger workflows which trigger AI calls which write back into your database ,one bad payload can cascade into duplicate actions ,billing spikes ,or data corruption .

3 . You have multi-tenant customer data . If one customer can ever see another customer's record through filters ,URLs ,or exports ,the problem is not cosmetic .It is an access control defect that can become a breach .

4 . You rely on third-party scripts for core conversion . Chat widgets ,analytics tags ,A/B testing tools ,and embedded forms can slow LCP past 2.5s ,break checkout flows ,or create supply-chain risk .

5 . You need launch timing tied to ads or investor demos . If paid traffic starts before security basics are done ,you risk wasting ad spend on broken onboarding while also creating support load from failed logins and missing emails .

DIY Fixes You Can Do Today

1 . Audit your DNS records . Remove duplicates ,confirm A/CNAME targets ,and make sure only one canonical domain wins .A messy DNS setup causes random outages that look like app bugs but are really routing mistakes .

2 . Check your email authentication now . Send a test message from your platform to Gmail and Outlook .If SPF/DKIM/DMARC fail ,fix that before launch because password resets depend on inbox delivery .

3 . Rotate any key you have pasted into chat tools or screenshots . Assume anything shared outside your secret manager is compromised .This includes screenshots sent to freelancers or copied into docs .

4 . Turn on Cloudflare protections you already pay for . At minimum enable SSL/TLS enforcement ,basic WAF rules where available ,and bot filtering options that do not block legitimate users .Start conservative so you do not break signups .

5 . Create one rollback plan . Write down exactly how you would revert the last deploy in under 10 minutes .If you cannot explain rollback clearly ,you are not ready to ship under pressure .

Where Cyprian Takes Over

Here is how I map checklist failures to the Launch Ready service deliverables:

| Failure area | What I fix in Launch Ready | Time window | |---|---|---| | DNS chaos / wrong domain routing | DNS cleanup ,redirect mapping ,subdomain setup ,canonical host strategy | Hour 0-8 | | Email going to spam / failing auth checks | SPF ,DKIM ,DMARC setup and validation across sending providers | Hour 0-12 | | Exposed secrets / weak env handling | Environment variable audit ,secret cleanup ,rotation guidance ,prod config separation | Hour 4-16 | | No edge protection / weak SSL posture | Cloudflare setup ,SSL enforcement ,basic caching rules ,DDoS protection review | Hour 4-18 | | Risky deployment flow / broken release process | Production deployment validation ,rollback path ,handover checklist creation | Hour 12-30 | | No monitoring / blind outages | Uptime monitoring setup ,alert routing ,basic observability handoff | Hour 18-36 | | Missing launch documentation / owner confusion after handoff) {#}*?* Wait need keep clean |

Typical handover output should include:

• Working domain and subdomain map
• Confirmed SSL status
• Passing email auth checks
• Secret inventory with rotation notes
• Production deploy verification
• Monitoring links
• Simple owner checklist for day-one operations

If your product already has customer data ，payments ，or complex automations ，I would strongly prefer this route over DIY because one missed permission issue can cost more than the whole sprint in refunds ，support time ，and lost trust .
