Patent-pending zero-knowledge architecture with cryptographic proof guarantees. Built for regulated industries that require mathematical certainty.
Patent-pending proof system that provides mathematical guarantees of file integrity, geographic residency, and deletion
Cryptographic proof that your file was successfully sharded and distributed
Cryptographic proof that shards are stored in specific geographic regions
Cryptographic proof that all shards were permanently deleted
Cryptographic proof that reconstructed file matches original
Cryptographic proof that shards were transmitted securely
Ongoing cryptographic proof that shards remain intact
Deploy Nebula's zero-knowledge architecture on your own cloud accounts. You control the keys, the infrastructure, and the data.
Production-ready Terraform infrastructure in under 10 minutes
Mathematically optimized for speed
Storage buckets live in your AWS/Azure/GCP accounts. You own the infrastructure and pay cloud providers directly.
Nebula never has access to your cloud credentials or encryption keys. Client-side encryption ensures zero-knowledge.
Terraform IaC provides complete audit trail. Show auditors exactly where data resides and who has access.
Export all data from your own cloud accounts at any time. No vendor lock-in, no migration fees.
Reed-Solomon erasure coding distributed across AWS, Azure, and GCP. Mathematically impossible to reconstruct without 10+ separate cloud account breaches.
Even with unlimited resources, here's what an attacker would need to do:
Your file is split into 10 encrypted pieces
Mathematical redundancy allows reconstruction from any 10 of 14 shards
Shards distributed across AWS, Azure, GCP in different regions
Your data survives even if 4 providers are compromised, down, or deleted
Unlike RAID or traditional backup, no single account holds complete data
Even if attacker gets 10+ shards, they're useless without your encryption key
EU data can stay in EU, US data in US, while still having cross-region redundancy
AWS region outage? Your data survives via Azure and GCP shards
Attacker must breach multiple providers with different security architectures
Need to change your multi-cloud distribution strategy? Nebula's rebalancing tool lets you migrate shard layouts across providers without downtime.
Transform compliance from a 2-3 week fire drill into a 5-minute self-service experience. Give auditors cryptographic proof without revealing data.
IT team manually exports logs, screenshots, and configuration files
Back-and-forth with auditors requesting clarifications
Perform full restore to prove backup integrity (hope it works!)
Fix gaps discovered during audit, provide additional evidence
Create read-only portal account with scoped permissions (2 min)
Auditor downloads cryptographic proofs, verifies geographic residency (3 min)
Auditor independently verifies Merkle tree proofs (5 min)
Mathematical proof replaces manual testing
Cryptographic proof that EU data stays in EU regions
GDPR/CCPA deletion requests with timestamped attestations
Merkle tree proof of file integrity without test restore
Mathematical proof that vendor cannot decrypt data
Export your entire backup catalog from your own cloud accounts at any time. No vendor lock-in, no migration fees, no negotiations.
Export all files, metadata, and cryptographic proofs to your local infrastructure or alternative backup provider.
With Bring Your Own Cloud, you already own the storage buckets. Access your shards directly without Nebula.
Our recovery CLI is open source. Reconstruct files from shards even if Nebula ceases to exist.
Client-side AES-256-GCM encryption. Your files are encrypted before leaving your browser. We mathematically cannot decrypt your data.
Why "we can't see your data" isn't marketing - it's math
Technical details: AES-256-GCM with PBKDF2 (600,000 iterations), SHA-256 hashing. Keys derived from user passwords never transmitted or stored server-side.
Reed-Solomon erasure coding provides mathematical redundancy beyond traditional backup approaches
Production-grade observability with continuous health checks and instant anomaly detection
Automated retention policies with cryptographic deletion proofs for GDPR/CCPA compliance
Keep EU data in EU, US data in US. Cryptographic residency proofs for GDPR Article 45 compliance.
Enterprise SSO, SAML 2.0, and role-based access control for zero-trust security
Production-ready SDKs, REST API, and enterprise integrations
Optimized for small-file workloads where traditional backup systems struggle
| Feature | NebulaProof | Traditional Backup (Veeam / Druva / Commvault) |
|---|---|---|
| Small-file handling (sub-1 MB IoMT / telemetry) | Optimized batching and fastest-shard recovery. 40-60% faster in our Wi-Fi tests. | Designed for large VMs and database dumps. Per-file overhead slows IoT-scale workloads. |
| Large-file throughput (multi-GB files) | Baseline parity with incumbents in measured scenarios. Ethernet benchmarks in progress. | Mature pipelines; strong performance for multi-GB jobs. |
| Zero-knowledge encryption | Customer-held keys, encrypted before leaving client | Vendor-managed encryption in most deployments |
| Cryptographic proofs (upload, residency, deletion, reconstruction, transmission) | Included across all tiers | Not part of standard feature set |
| Multi-cloud erasure coding with region policies | Dynamic placement + geographic enforcement | Limited Typically single-cloud, manual region configuration |
Note: Performance comparisons based on internal testing in controlled environments. Wi-Fi test results: 40-60% faster for small-file workloads (<1MB). Large-file benchmarks (1TB+) are in progress on Ethernet connections. Your results may vary based on network conditions, hardware, and workload characteristics.
Purpose-built for continuous telemetry, transaction logs, and document retention at scale
Optimized for workloads that generate thousands of small files per hour—where traditional backup systems struggle with per-file overhead.
Automated ingestion from your cloud storage buckets with comprehensive cryptographic proof generation
Drop files into your designated Azure/AWS/GCP bucket. Nebula automatically detects uploads via webhooks, downloads files, shards them with erasure coding, distributes shards across multiple clouds, and generates comprehensive cryptographic proofs.
Every ingested file generates 8 different types of cryptographic proofs
SHA-256 hash + Merkle tree of all shards. Proves file was successfully ingested and distributed.
Attestation that shards are stored in specified regions. Meets GDPR Article 45 requirements.
TLS 1.3 verification + node acknowledgment receipts. Proves shards were securely transmitted.
Merkle tree validation every 5 minutes. Detects corruption and triggers auto-heal.
Azure-native ETag verification. Proves blob integrity at storage layer.
AWS S3 metadata + Content-MD5 verification. Proves object integrity.
Google Cloud Storage CRC32C checksum. Proves object integrity at GCP layer.
SHA-256 hash of original file before encryption. Independent verification without Nebula credentials.
Merkle tree validation every 5 minutes with automatic corruption detection and self-healing
Every 5 minutes, Nebula validates the Merkle tree of all shards. Detect bit rot, corruption, or tampering instantly.
When corruption is detected, Nebula automatically regenerates the corrupt shard from parity data and replaces it.
Periodic test reconstructions validate that erasure coding works correctly and all shards are retrievable.
Customer support that respects zero-knowledge architecture. We can help debug without ever seeing your data.
