Prowler - Multi-Cloud Security and Compliance Scanner

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

## Prowler Multi-Cloud Security and Compliance Scanner

Deploy a ready-to-run cloud security assessment tool on your own EC2 instance within minutes. Built on Prowler - the open source multi-cloud security scanner - this AMI runs hundreds of checks against a cloud account and reports exactly which controls pass, which fail, and which compliance requirement each maps to. It covers AWS, Azure, Google Cloud, Kubernetes, Microsoft 365 and GitHub from one command line, and maps findings onto dozens of published frameworks including CIS, PCI DSS, HIPAA, SOC 2, ISO 27001, NIST and FedRAMP.

## Why This Scanner Instead of Alternatives

• No per-scan or per-asset fees - Unlike SaaS security posture platforms that charge per account or per finding, this AMI runs on hardware you control with predictable costs
• No credentials baked in - The image ships with no cloud credentials of any kind; you attach your own read-only identity, and on AWS that can be an instance role so no secret is ever written to the instance
• Nothing withheld - This is the full Prowler engine: every check, every provider and every compliance framework, not a reduced edition
• Standard outputs - Findings are written as CSV, OCSF JSON and a self-contained HTML report that integrate with any evidence or SIEM workflow

## What This Image Is, Stated Plainly

This ships the Prowler command-line scanner, deliberately - not the separate Prowler App web interface, which would add a database and several network listeners to a security appliance. There is no web console and nothing listens on this instance beyond SSH. Prowler measures and reports: it reads cloud provider APIs using the read-only identity you give it and never changes anything in your account.

## Credential-Free Scanning, Working from First Boot

You do not need a cloud account to prove the scanner works. The image ships Prowler's infrastructure-as-code provider and an example fixture, so a complete, genuine assessment of Terraform runs with no credentials at all - a baseline runs automatically on first boot. This is a real, shipped feature: point it at your own Terraform, CloudFormation or Kubernetes manifests to scan them for misconfigurations before you deploy.

## Assess Your Own Cloud

Attach a read-only identity for the account you want to assess - an AWS instance role with SecurityAudit and ViewOnlyAccess is the recommended path on AWS - then run a full assessment with a single command. Restrict a run to one service, one severity, or one compliance framework, and write the results wherever you choose.

## Scheduled Assessments

A systemd timer runs an assessment daily with a randomised delay so a fleet does not stampede, keeping dated reports. Out of the box it points at the credential-free IaC provider against an empty directory, so it is a no-op until you either drop manifests in or point it at a cloud provider - the image makes no assumption about your estate.

## Fail-Closed by Design

For a security scanner the worst outcome is a confident wrong answer. This image verifies the integrity of the scanner before every scheduled run - the binary must match the checksum recorded when the image was built - and a failed first boot stops the schedule rather than filing a clean-looking report from a broken scanner.

## Minimal Attack Surface

Prowler binds no port and runs no daemon. The only listening service is SSH for administration; all cloud access is outbound. There is no login and no baked-in credential of any kind.

## Use Cases

• Multi-cloud posture assessment - Run hundreds of security checks against an AWS, Azure, GCP or Kubernetes account with a read-only identity and see exactly what passes and fails
• Compliance evidence generation - Map findings onto CIS, PCI DSS, HIPAA, SOC 2, ISO 27001, NIST or FedRAMP and export CSV, OCSF JSON and HTML for security reviews and attestation
• Shift-left IaC scanning - Scan Terraform, CloudFormation and Kubernetes manifests for misconfigurations with no cloud credentials, on first boot or on a schedule
