SFTP Integration Features

Secure file transfer protocol access to object storage with enterprise authentication and management.

Native Protocol

Built-in SFTP server eliminates external gateway appliances with direct protocol translation from SFTP to S3 operations.

Enterprise Authentication

Support for SSH keys, password authentication, and LDAP/AD integration for centralized user management and access control.

Bucket Mapping

Flexible namespace mapping between SFTP directories and S3 buckets for intuitive file system semantics over object storage.

Audit Logging

Comprehensive logging of uploads, downloads, and deletes, integrated with AIStor's unified audit trail for compliance.

Advanced Security

AIStor SFTP delivers enterprise-grade security with flexible authentication options, configurable encryption, and compliance-ready controls—all unified with your existing identity infrastructure.

Why AIStor is Different

Legacy SFTP workflows rely on external gateway appliances that translate file operations to object APIs—adding hardware costs, latency, and failure points. Separate authentication systems for SFTP and S3 create fragmented security and inconsistent policy enforcement. AIStor eliminates the gateway layer entirely.

SFTP Support
Built-in protocol translation with no external gateway appliances required.

One

Identity System
Unified IAM and LDAP/AD authentication for both SFTP and S3 access.

Zero

Added Latency
Direct-to-storage writes without protocol translation hops.

Business Impact

Legacy Application Support

Enable existing SFTP-dependent applications and workflows to access object storage without code changes.

Reduced Infrastructure

Eliminate SFTP gateway appliances, reducing hardware costs, network complexity, and maintenance overhead.

Unified User Management

Single identity system for SFTP and S3 access simplifies administration and ensures consistent security policies.

Compliance Simplification

Unified audit logging across SFTP and S3 operations provides complete visibility for regulatory tracking.
