The First 10 Cloud Security Checks Every Startup Should Run
A practical AWS and GCP security readiness checklist for startups preparing for customer trust, audits, and basic production safety.
Cloud security does not need to start with a massive compliance program. For most startups and small businesses, the first step is simpler: find the obvious risks before a customer, auditor, or attacker does.
1. Confirm MFA for every human user
If a person can access production cloud resources, MFA should be enabled. This is basic, but it is still missed.
2. Remove shared admin accounts
Every user should have named access. Shared accounts destroy accountability and make incident investigation harder.
3. Review public exposure
Check public buckets, load balancers, security groups, firewall rules, databases, dashboards, and admin panels. Public should be intentional, not accidental.
4. Audit long-lived access keys
Long-lived keys are easy to leak and hard to rotate. Review who owns them, where they are used, and whether workload identity or short-lived credentials can replace them.
5. Turn on audit logging
You need records of who did what. In AWS that usually means CloudTrail. In GCP, Cloud Audit Logs are the foundation. Logging should exist before the incident.
6. Protect secrets
Secrets do not belong in repositories, local scripts, or random environment files. Use a secrets manager and define who can read each secret.
7. Check backup and restore
Security includes recovery. Ransomware, accidental deletion, and bad deploys all become worse when restores are untested.
8. Review encryption defaults
Most managed services can encrypt data at rest. Confirm the defaults are enabled and understand where customer-managed keys are actually necessary.
9. Look at third-party access
Vendors, contractors, CI/CD systems, and monitoring tools often accumulate permissions. Review them the same way you review employees.
10. Create a remediation backlog
The output of a security review should not be panic. It should be a ranked backlog: critical risks first, then high-value improvements, then documentation.
If customer security questions are starting to arrive, the Cloud Security & Readiness Review gives you a practical risk-ranked backlog and readiness notes for customer conversations.
