OUTSCALE Object Storage review
A compliance-focused S3 service for mid-market and enterprise teams needing European cloud storage.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OUTSCALE Object Storage is a cloud service for storing and managing unstructured data, including files, media, websites, backups, archives, and application data. It is designed for mid-market and enterprise organizations that need S3-compatible access and sovereign cloud infrastructure, particularly across OUTSCALE regions in Europe. REST API access over HTTPS, AWS S3 API compatibility, AWS CLI support, and compatibility with S3 tools make it suitable for applications and operational workflows built around the S3 ecosystem.
Pricing is centered on the Enterprise plan at €0.025 per GiB per month, billed monthly on actual usage. Inbound traffic is included, and outbound traffic is free in listed Europe and US regions. The paid structure suits organizations budgeting for ongoing object storage rather than teams looking for a free starting tier. The service also provides lifecycle expiration rules, bucket versioning, access control lists, pre-signed URLs, server-side encryption, and object locking with compliance retention. These controls support storage policies for backups, archives, and regulated data.
Its storage architecture combines erasure coding with replication across availability zones, while the published compliance posture includes SOC 2, ISO 27001, and GDPR. Email, phone, ticket, and documentation support are available, with 24/7 support listed. OOS is a strong fit for teams that prioritize S3 compatibility, compliance controls, and regional infrastructure. Organizations that need a free plan, a graphical platform, or higher-level S3 bucket replication should consider a different service.
