Frequently Asked Questions

Everything you need to know about CloudNexus Storage.

Is CloudNexus Object Storage compatible with AWS S3?

+

Yes, CloudNexus Object Storage is fully S3-compatible. You can use any S3 SDK, CLI tool, or third-party application without modification. Simply point your configuration to our endpoint and use your API credentials.

How does data replication work across regions?

+

We offer automatic cross-region replication (CRR) that replicates objects in real-time to any region you specify. Replication is asynchronous and transparent — your application continues to operate normally. RPO is zero and RTO is under 60 seconds.

What encryption options are available?

+

CloudNexus offers server-side encryption (SSE-S3, SSE-KMS), client-side encryption (SSE-C), and bring-your-own-key (BYOK) with HSM-backed key management. All data is encrypted at rest with AES-256 and in transit with TLS 1.3.

Can I migrate from AWS S3 or Azure Blob Storage?

+

Absolutely. Our CloudNexus Import Tool provides parallel, high-speed transfer from AWS S3, Azure Blob, and Google Cloud Storage. It handles versioning, metadata, and permissions automatically with zero downtime.

What compliance certifications do you have?

+

CloudNexus Storage is compliant with SOC 2 Type II, HIPAA, PCI-DSS, GDPR, and ISO 27001. We also offer FedRAMP Moderate and are working towards FedRAMP High. All compliance documentation is available in our trust center.

Is there a free tier available?
