What Cloud Security Tools Do
Cloud security tools check that your AWS, Azure, or Google Cloud environment is configured the way you think it is. They scan for storage buckets open to the internet, IAM roles with far more permission than needed, unencrypted volumes, security groups that allow all inbound traffic, and drift from a hardened baseline such as the CIS Benchmarks.
Misconfiguration, not clever exploits, is the leading cause of cloud incidents at small companies. The free tools on this page are cloud security posture management in miniature: run them against your account, get a prioritised list of findings mapped to CIS or your compliance framework, and rerun them in CI so the fixes stay fixed.
How to Choose a Cloud Security Tool
- Pick a scanner that covers every cloud you actually use; multi-cloud teams should avoid single-provider tools.
- Prefer tools that map findings to CIS Benchmarks, SOC 2, or ISO 27001 controls so the output doubles as audit evidence.
- Make sure it can run on a schedule or in CI, not only on demand; posture drifts within weeks.
- For infrastructure-as-code teams, add a scanner that checks Terraform or CloudFormation before deployment.

Free CIS Controls Gap AssessmentCloud Security Tools: Frequently Asked Questions
What is cloud security posture management?
CSPM tools continuously compare your cloud configuration against a set of security rules and report the gaps: public buckets, excessive IAM permissions, missing encryption, disabled logging. Commercial CSPM adds dashboards and remediation; the free tools here provide the same checks as scripts or CLI scanners.
Is the cloud provider responsible for my security?
Only for the infrastructure under the shared responsibility model. Configuration of your accounts, identities, data, and workloads is your responsibility, which is exactly what these tools check.
Which CIS Benchmark applies to my cloud?
CIS publishes benchmarks for AWS, Azure, Google Cloud, Kubernetes, and the major operating systems. The free scanners on this page implement those checks; IRM's free CIS Controls Gap Assessment covers the broader CIS Controls v8.1 safeguards that sit above them.
