If a vendor offers its security software as a SaaS solution on AWS, where can a company purchase that solution?

Companies can purchase third-party software, including Security as a Service (SaaS) solutions, directly from AWS Marketplace. This digital catalog simplifies the procurement process by offering a wide range of software from independent vendors that runs on AWS. AWS Partner Solutions Finder is used to locate AWS Partners, not to purchase software directly. The AWS Support Center is for managing AWS support cases, and the AWS Management Console is the web-based interface for managing AWS services, neither of which is a purchasing platform for third-party software.
