Upgrading from Prowler v2 to Prowler v3


Though Jit currently uses Prowler v3 to scan for infrastructure runtime misconfigurations, users who onboarded with previous iterations of Jit may still be using Prowler v2.

Prowler v3 is a security and compliance assessment tool designed to help organizations evaluate and improve the security of their cloud environments, including Amazon Web Services (AWS), Microsoft Azure and Google Cloud. It has been fully rewritten in Python, offering significant performance improvements and extended functionality over its predecessor, Prowler v2.

Prowler v3 provides a wide range of security checks and compliance framework support. With that it allows users to scan their cloud infrastructure quickly, identify potential vulnerabilities, and take action to address those issues.

Prowler v3 provides the following improvements over v2:

  • Improved performance— Up to 30x improvement in speed, depending on your environment.
  • Support for multiple cloud providers.
  • Improved checks.
