About Enveil

Enveil is a Privacy Enhancing Technology (PET) company focused on protecting Data in Use - data that is actively being processed or analyzed. Their flagship product line, ZeroReveal, enables organizations to perform encrypted searches, analytics, and machine learning operations while keeping both the queries and results encrypted throughout the entire process.

What does Enveil do?

The ZeroReveal platform uses homomorphic encryption and other privacy-preserving technologies to allow organizations to extract insights from sensitive data across organizational and jurisdictional boundaries without exposing the underlying information. The technology operates as a proxy layer above existing data infrastructure, meaning organizations can maintain their current storage methods and access controls while adding privacy-preserving capabilities.

The platform's core capability is enabling 'Trusted Compute in Untrusted Locations' - allowing secure data processing outside of controlled environments without compromising security. This includes the ability to securely evaluate encrypted machine learning models against distributed data sources, perform encrypted searches across multiple datasets, and enable secure cross-organizational data collaboration.

What makes Enveil different?

A key differentiating aspect of Enveil's approach is its decentralized architecture that allows participating organizations to maintain control and ownership of their data assets. Unlike other PET solutions that may require data pooling or centralization, Enveil's technology enables secure computation over data in its existing location and format. The company has focused on making homomorphic encryption practical for business use - their 3.0 release achieved processing speeds over 1000 times faster than their initial 2017 offering.

Use cases and industries

The technology has found applications across multiple sectors including financial services, healthcare, and government. Common use cases include secure data monetization, cross-jurisdictional data sharing, fraud investigation involving PII data, and secure AI/ML model deployment. For example, banks can conduct privacy-preserving fraud investigations across jurisdictional boundaries, while pharmaceutical companies can utilize public datasets without revealing their research interests.

The platform is particularly relevant for organizations operating under strict regulatory requirements or dealing with sensitive intellectual property. Recent implementations include providing Secure AI capabilities for the U.S. Army's Project Linchpin initiative, focusing on delivering a trusted AI/ML operations pipeline in multi-domain environments.

Technical specifications

Enveil's ZeroReveal platform is built on a combination of homomorphic encryption, secure multiparty computation, and trusted execution environments. The software integrates with existing security infrastructure and data systems through standard APIs. While the technology introduces some computational overhead compared to processing unencrypted data, the company has focused on optimization - with their latest version returning encrypted search results across millions of records within seconds rather than the hours or days required by earlier implementations.

The solution includes native support for encrypted geospatial queries, robust fuzzy matching capabilities, and the ability to handle large encrypted files like videos or high-resolution images. For edge computing scenarios, the platform has been optimized to minimize encrypted query file sizes for operation in low-bandwidth environments.
