A KGreen technical whitepaper on KVault — US Patented Split & Spread
HSMs secure the encryption keys. KVault secures the data itself — so a breach of any single location is worthless.
Traditional security models are failing against modern threats. While Hardware Security Modules (HSMs) secure encryption keys inside a physical vault, KVault makes the data itself inherently secure — by fragmenting and distributing it across independent locations, so that compromising any single location yields nothing usable.
| Feature / Aspect | Traditional HSM | KVault | Key Advantage of KVault |
|---|---|---|---|
| Primary Function | Securely stores and manages encryption keys in tamper-proof hardware. | Encrypts, splits and distributes data across multiple storages (cloud/local) with integrated key and data security. | Combines data security + key security + data resilience in one software-defined layer. |
| Architecture | Hardware appliance, on-premises, requires physical deployment. | Software-defined or virtual appliance; deployable across hybrid / multi-cloud environments. | No dependency on proprietary hardware — flexible, scalable and cost-effective. |
| Data Protection Scope | Protects keys only — not the actual data. | Protects both data and keys — confidentiality, integrity and availability. | Eliminates single point of failure — even if one storage is breached, the data is useless. |
| Data Splitting & Distribution | Not supported — data remains in one location. | Proprietary algorithm splits data and distributes it across AWS, Azure, local, etc. | US-Patented Split & Spread — superior protection from data theft or ransomware. |
| Cloud Compatibility | Limited — often needs special integration with each cloud provider. | Cloud-native and multi-cloud ready (AWS, Azure, GCP, private cloud). | Works seamlessly across environments — true cloud independence. |
| Scalability | Scaling requires additional HSM hardware or licenses. | Scales horizontally via software instances and containerised deployments. | Pay-as-you-grow scalability — no hardware bottleneck. |
| Cost & Maintenance | High CAPEX (hardware, certification, maintenance). | Low CAPEX / OPEX — pure software, minimal infrastructure. | Lower total cost of ownership (TCO). |
| Deployment Time | Weeks to months (procurement, setup, compliance). | Hours to days — deployable as a VM, container or API service. | Rapid deployment and minimal integration effort. |
| High Availability / DR | Requires secondary HSMs and complex sync mechanisms. | Inherent redundancy — data shards stored in multiple independent locations. | Built-in disaster recovery and resilience. |
| Integration | Works primarily via PKCS#11 or proprietary APIs. | Offers REST APIs, SDKs and plugin integrations for apps, SIEMs and storage layers. | Developer-friendly — integration-ready for modern architectures. |
| Compliance | FIPS 140-2/3 certified hardware. | Integrates with an HSM for FIPS compliance, or operates standalone with AES-256 / RSA-4096. | Meets compliance + adds multi-layered data protection. |
| Data Residency / Sovereignty | Hardware-bound, limited flexibility for cross-border replication. | Shards can be placed in-country while maintaining redundancy globally. | Compliance with data-sovereignty laws (RBI, GDPR). |
| Ransomware & Insider Threat | Focused on key protection; does not prevent data encryption or misuse. | Data shards and keys stored separately — no single insider or attacker can reconstruct the complete data. | Unique ransomware & insider-threat immunity. |
HSMs remain valuable for safeguarding cryptographic keys — but they secure the key, not the data. Once data is decrypted, or if the environment is misconfigured, the protection ends. KVault shifts the model from key-centric to data-centric: it assumes a breach will happen and ensures that what an attacker steals is worthless. Whether deployed alongside an existing HSM or on its own, KVault closes the exposure gap that key-centric security leaves open.
