What the publisher says
As described on Microsoft Marketplace.
S3Proxy is an open-source, self-hosted S3-compatible gateway that provides an Amazon S3 API interface for a variety of storage backends. Built on top of the jclouds library, S3Proxy enables applications and tools that support the Amazon S3 protocol to store, retrieve, and manage data using local filesystems, cloud object storage services, and other supported storage providers. It acts as a translation layer between S3-compatible clients and the underlying storage backend, allowing users to leverage S3 APIs without requiring Amazon S3 itself. S3Proxy can be deployed on local systems, private servers, virtual machines, containers, Kubernetes clusters, and cloud infrastructure.
S3Proxy is designed for developers, system administrators, organizations, and storage providers that need S3-compatible object storage access while maintaining flexibility in backend storage choices. It supports bucket and object operations, multipart uploads, AWS Signature Version 2 and Version 4 authentication, and integration with various storage providers through jclouds. By exposing a standard S3-compatible interface, S3Proxy simplifies application migration, testing, backup solutions, hybrid-cloud architectures, and development environments that rely on S3 APIs.

Confirmed means matched to a public authoritative registry. Claimed means the vendor or its listing states it, not yet cross-checked. A framework not shown was not found in any source we hold, which is not evidence against it. Not listed means a scoped registry check found no match for this vendor's domain: a No is a scoped registry check, not a compliance judgment. Confidence bands: 95% domain-verified, 90% registry-checked, 80% self-attested, 70% weak signal. Self-attested items marked “vendor's site” are gathered from the vendor's own website and are not verified by us.

Unknown means this listing does not publish a repository. It is not a statement that the code is closed, and a linked repository is not a claim that the publisher wrote it: the registry computes that relationship privately and does not publish it.
Evidence risk is the share of the build you cannot see before you deploy, not a security rating. Sign in to see the layer-by-layer basis for this band.
