Advanced Local S3 Storage Capabilities for Secure, On-Prem Object Storage
Organizations relying on cloud-only storage face rising costs, unpredictable latency, and exposure to ransomware attacks targeting online repositories. Critical backups, unstructured data, and virtual workloads need fast, secure, local object storage that stays under your control.
When cloud outages, egress fees, or cyberattacks strike, recovery slows down—or comes to a halt. Traditional NAS/SAN systems aren’t optimized for the scale, immutability, or application compatibility required for today’s AWS compatible S3-based workloads, leaving gaps in resilience and performance.
StoneFly solves these challenges with high-performance local AWS S3 storage powered by a fully AWS S3 compatible local storage architecture.
The platform integrates our patented Air-Gapped Vault® with built-in immutability to protect backups and mission-critical data from ransomware and unauthorized modification. Intelligent caching and tiering deliver private-cloud agility, while seamless compatibility with Veeam, Rubrik, Commvault, Veritas, HYCU, and enterprise hypervisors—including VMware, Hyper-V, Proxmox, KVM, and Citrix—ensures effortless deployment. For resilience across locations, multi- site replication and DR workflows provide continuous data availability and rapid recovery.

Explore How StoneFly's Amazon S3 Compatible Storage Appliances Work
Integrated Ransomware Protection and Security Features in S3 Object Storage
StoneFly delivers enterprise-grade protection for local AWS S3 storage with layered security controls designed to prevent data loss, protect against ransomware, and ensure long-term integrity. These capabilities strengthen your AWS S3 compatible local storage environment and secure mission-critical backups, archives, and unstructured data.
Air-Gapped Vault® (Patented & Immutable)
StoneFly’s patented Air-Gapped Vault® creates a physically and logically isolated repository that ransomware cannot access or modify. Immutable storage ensures backup data remains tamper-proof, preventing encryption, deletion, or corruption. This provides a secure last line of defense for your AWS S3 object storage appliance.
Encryption at Rest and In Transit
All data stored and transferred through the system is protected with strong encryption standards. Encryption at rest safeguards object data on the appliance, while encryption in transit prevents interception or unauthorized access during data movement. This ensures complete confidentiality across your entire AWS S3 compatible storage environment.
Volume Deletion Protection
Built-in deletion safeguards protect storage volumes and critical datasets from accidental removal or malicious attempts to erase data. The appliance enforces secure deletion workflows and retention controls, ensuring your local object storage remains intact and recoverable even during high-risk events.
Access Control and MFA
Granular role-based access controls allow administrators to define user permissions across applications, workloads, and storage tiers. Multi-factor authentication adds another layer of security, ensuring only authorized users can access sensitive data or manage your AWS S3 storage solutions.
Sync and Async Replication
StoneFly supports both synchronous and asynchronous replication between sites, appliances, or cloud targets. This enables continuous data availability, efficient failover, and fast recovery. Replication integrates seamlessly with your local AWS S3 storage workflows for robust business continuity.
Immutable Snapshots
Snapshots lock object data in an unchangeable state, preventing alteration, deletion, or overwriting. Immutable snapshots provide a reliable recovery point in the event of ransomware attacks or internal compromises, strengthening the resilience of your AWS S3 compatible local storage.
Compliance and Retention Policy Support
Industry compliance requirements are supported through flexible retention policies and WORM (Write Once, Read Many) capabilities. These controls ensure that regulated data remains preserved, auditable, and unmodified throughout its lifecycle—ideal for long-term archives, backups, and sensitive workloads.
Automated Threat Detection and Response
The appliance continuously monitors storage activity for suspicious behavior, unauthorized access, or abnormal write patterns. Automated detection triggers immediate protective actions to isolate threats and safeguard object data. This real-time intelligence strengthens the security posture of your AWS S3 object storage appliance against evolving attacks.
