Vaultree
Encryption-as-a-service platform enabling searchable and computable encryption over data using standard hardware, so organizations can query and process encrypted data without decrypting it first.

Vaultree was founded in Cork, Ireland in September 2020, building data-in-use encryption technology that combines Enhanced Searchable Symmetric Encryption (ESSE) with elements of Fully Homomorphic Encryption (FHE) research to let organizations search, query, and compute over encrypted data without decrypting it on standard commodity hardware — a capability that fully homomorphic encryption alone has historically been too computationally expensive to deliver in production at scale.
The company closed a $12.8 million Series A round in December 2022, co-led by Molten Ventures and Ten Eleven Ventures with participation from SentinelOne, building on an earlier $3.3 million seed round, for roughly $16 million raised in total. Vaultree describes itself as a Google Cloud partner, delivering what it calls one of the first fully managed, functional data-in-use encryption schemes available commercially.
Vaultree’s differentiation from competitors like Titaniam and Sotero in the data-in-use encryption space is its specific technical approach (ESSE combined with FHE-adjacent techniques) aimed at making genuinely encrypted search and computation practical on standard hardware rather than requiring specialized cryptographic accelerators.
Innovation Matrix Assessment
Progressed from a 2021 seed-stage encryption-in-use concept to a functional, Google Cloud-partnered commercial product within roughly two years, a fast pace for genuinely hard applied-cryptography engineering.
If performant as claimed, encrypted search and computation reduces the operational risk window during data processing, though integration into existing application query patterns likely requires real engineering effort.
A $12.8M Series A with participation from SentinelOne as a strategic investor is a positive but still early-stage momentum signal relative to more mature data-security platforms.
Making searchable, computable encryption practical on standard hardware — rather than requiring the customer to fully decrypt data before use — is a structurally different and technically difficult approach compared to conventional at-rest/in-transit encryption.
No independent third-party cryptographic audit or production-scale performance benchmark was found; efficacy claims rest on vendor-reported technical descriptions and the Google Cloud partnership.
As regulatory and architectural pressure to minimize plaintext data exposure grows, practical encrypted-computation techniques address a forward-looking and increasingly important data-protection need.
Why CISOs Should Care
Vaultree lets organizations query and process sensitive data while it remains encrypted, which reduces the exposure window that exists in most encryption schemes where data must be decrypted before an application can search or compute over it.
What Makes It Different
Its combination of Enhanced Searchable Symmetric Encryption and fully-homomorphic-adjacent techniques is aimed specifically at making encrypted search and computation performant on standard hardware, addressing the computational overhead that has historically limited FHE's practical enterprise use.
The Matrix Verdict
52/100 — INCREMENTAL INNOVATOR
A technically ambitious, Series A-stage encryption-in-use vendor tackling a genuinely hard cryptographic engineering problem, with credible institutional and strategic (SentinelOne) backing, though still early in proving broad commercial adoption. An Emerging Innovator with real technical depth.
Editorial Note: Claims vs. Verified Findings
Funding figures and the SentinelOne strategic participation are corroborated by TechCrunch's own reporting; performance claims relative to traditional FHE were not independently benchmarked.
