Private AI infrastructure accelerating AI adoption
without sensitive data exposure
As generative AI and AI agents are deployed at an accelerating pace, organizations face growing pressure to send their most sensitive internal data into external AI environments.
DESILO Private AI performs the entire AI inference pipeline on encrypted data — so information is never exposed in plaintext, not even for a single moment. It is a new AI infrastructure that preserves both the value of AI and your data sovereignty.

End-to-End Private AI: inference on encrypted data
Inference on ciphertext
User input is encrypted on the device before being sent to the server, and the AI model performs every computation directly on the encrypted data.
Private LLM support
We deliver a one-stop, full-package Private LLM — purpose-optimized and ported for FHE environments. Deploy a validated Private LLM immediately, with no model retraining or in-house conversion work required.
Deployment flexibility
Deploy on-premises, in the cloud, or in a hybrid configuration — matching your security policy and infrastructure.
Regulatory compliance
Technically satisfies the requirements of global data regulations including GDPR, the EU AI Act, and Korea's Personal Information Protection Act.
AI should be secure — without giving up data sovereignty.
The world's first and only End-to-End FHE LLM
DESILO runs the entire inference pipeline — from input to output — on top of homomorphic encryption, and is the only Private AI implementation publicly demonstrated to do so today.
5th-generation homomorphic encryption: the GL Scheme
Powered by the GL Scheme — the next-generation homomorphic encryption algorithm co-developed by FHE inventor Craig Gentry and DESILO — delivering dramatic performance gains over CKKS on the large-scale matrix operations at the core of AI workloads.
A global standard reference
DESILO Private AI was selected as the sole LLM reference implementation in the HES FHE Benchmarking Suite jointly led by AWS and Google, defining the future performance standard for FHE-based AI.
Full-stack optimization
From AI model compression and FHE algorithms to hardware acceleration — DESILO provides the only Private AI stack with integrated optimization across both software and hardware.
The AI era is here. Start with the most sensitive data — protected from day one.
Run risk analysis, credit scoring, and internal report automation on undisclosed financials, customer transaction histories, and credit data — without ever exposing them to external AI services.
Feed sensitive medical data — EMR, genomic information — into AI diagnostic-support models in encrypted form, securing data sovereignty in healthcare.
Use internal classified documents and policy materials with AI agents for analysis, summarization, and decision support — without sending data to any external server.
Expand the scope of in-house AI agent automation while protecting confidential strategy materials, HR records, and sales intelligence.
