Nasuni
Cloud-native file data platform providing continuous, versioned backup and rapid ransomware recovery for enterprise unstructured file data, positioned as a replacement for traditional NAS and file-server backup.

Nasuni was founded in Boston in 2009, building a cloud-native file storage platform designed to replace traditional network-attached storage (NAS) infrastructure with a model where files are continuously versioned and stored immutably in the cloud, with edge appliances caching active data locally for performance. Because every file change is captured as a version in cloud object storage, the platform can restore ransomware-encrypted files to a point in time within minutes rather than requiring a full traditional backup-restore cycle.
The company has raised roughly $219 million from investors including North Bridge Venture Partners, Goldman Sachs, and Telstra Ventures, reaching a reported $1.2 billion valuation. Its ransomware-recovery positioning specifically emphasizes speed — the company markets recovery happening “in seconds to minutes” rather than the hours-to-days recovery windows common with traditional backup-and-restore approaches for large file estates.
Nasuni competes with Panzura in the hybrid-cloud file storage and ransomware-resilience space, as well as with traditional NAS vendors adding ransomware-detection features, differentiating primarily through its cloud-native, continuously-versioned architecture built from the ground up rather than retrofitted onto on-premises hardware.
Innovation Matrix Assessment
Built a cloud-native, continuously-versioned file platform from the ground up and has sustained iteration on ransomware-recovery speed as a core differentiator over more than a decade.
Minute-scale file recovery meaningfully reduces the operational disruption and downtime security and IT teams face during a ransomware incident compared to traditional backup-restore cycles.
A $1.2 billion valuation and $219M raised from investors including Goldman Sachs indicate solid, sustained market confidence.
A cloud-native, continuously-versioned architecture is a meaningfully different approach to file storage and recovery than traditional NAS-plus-backup, though it shares conceptual ground with competitors like Panzura pursuing similar architectures.
Long operating history and enterprise adoption suggest real production reliability, but independent, third-party-verified recovery-time benchmarks were not found.
As ransomware continues to target unstructured file data and recovery speed becomes a key business-continuity metric, fast, granular file-recovery architectures remain strategically important.
Why CISOs Should Care
Nasuni's continuous file versioning means ransomware-encrypted files can typically be restored to their last-known-good state within minutes rather than requiring a lengthy traditional backup restore, which directly shrinks the operational and business-disruption window during a ransomware incident.
What Makes It Different
Built cloud-native from the outset with continuous per-file versioning, rather than retrofitting snapshot or backup capability onto traditional on-premises NAS hardware, giving it a more granular and faster recovery model.
The Matrix Verdict
58/100 — INCREMENTAL INNOVATOR
A well-capitalized, cloud-native file storage platform with a genuinely fast ransomware-recovery architecture and unicorn-level valuation, competing in a growing category of cloud-native NAS replacements. A strong Meaningful Innovator.
Editorial Note: Claims vs. Verified Findings
Funding and valuation figures are corroborated by VentureBeat and Crunchbase-sourced reporting; specific recovery-time claims ("seconds to minutes") are vendor-stated and were not independently timed or benchmarked.
