Wasabi Hot Cloud Storage

Wasabi is a hot cloud object storage service offering S3 compatibility with simple, predictable pricing (no fees for egress or API requests). Key security features include bucket-level immutability (Object Lock) to protect against ransomware, fine-grained access controls, and data encrypted at rest and in transit. It's designed as a high-performance, low-cost storage tier for backup, archive, and big data. Like B2, it's typically accessed via third-party backup software.

It ranks for its cost-effective, immutable storage capabilities, making it a popular enterprise backup target and secure data lake.
