What Secretarium does

Secretarium is a London-based confidential computing company that builds hardware-isolated data-processing infrastructure using Intel SGX Trusted Execution Environments. Founded in 2018, the company addresses the tension between data utility and data confidentiality for organisations that handle sensitive information—primarily financial institutions, central banks, and government agencies—by enabling computation on encrypted data where even privileged infrastructure operators cannot read inputs or outputs, accompanied by cryptographic attestation of correct execution.

The product portfolio centres on two platforms: Klave, the developer-facing confidential application platform that abstracts enclave complexity and supports WASM smart contracts; and SDLT (Secure-Enclave Distributed Ledger Technology), a BFT-RAFT consensus ledger that combines TEE-isolated nodes with distributed-ledger auditability. Surrounding modules include Klave for AI (Private RAGs and SMCP for AI agents), the Honest Computing integrity-by-design framework, and vertical solutions covering DORA compliance, secure tokenisation and trading, secure PII processing for AML and fraud, offline CBDC, and the Amlytic cross-institution financial-crime analytics platform built with FutureFlow. Technology partnerships with Intel (SGX), Thales (hardware security and offline CBDC since 2022), and Nvidia (GPU compute) anchor the stack, while a Klave Marketplace of templates provides reusable building blocks for key management, tokenisation, and proof-of-existence.

Revenue is generated through annual and multi-year platform subscription licensing, optional perpetual on-premises licences, professional services delivered with system-integration partners, and technology licensing royalties. Go-to-market blends an enterprise field-sales motion targeting regulated buyers with a product-led-growth developer channel through Klave. The company holds ISO 27001, Cyber Essentials, and JOSCAR certifications and has been awarded an HM Government Framework Contract, signalling procurement-readiness in regulated verticals.

Core offering

Secretarium builds and sells confidential computing infrastructure, centred on the Klave Platform and SDLT (Secure-Enclave Distributed Ledger Technology), that enables organisations to process and share sensitive data while keeping it encrypted in memory inside hardware-isolated enclaves (Intel SGX). It packages the underlying Pliant protocol, BFT-RAFT consensus, WASM smart contracts, and remote attestation into a developer platform and a set of vertical solutions (Secure PII Processing, Klave for AI, DORA Compliance, Secure Tokenisation, Amlytic financial-crime analytics, Offline CBDC) sold to financial institutions, central banks, and government/defence buyers.

Product overview

Secretarium is a Private Cloud Compute company pioneering Honest Computing — a framework ensuring computer systems guarantee demonstrable transparency, reliability, and ethical operation. The company offers a platform-plus-modules architecture centered on two core products: Klave Platform and SDLT (Secure-Enclave Distributed Ledger Technology), both built on Confidential Computing technology. Klave is the flagship zero-trust confidential application platform enabling developers to deploy privacy-preserving applications within seconds. SDLT is the third-generation distributed ledger combining TEEs with DLT for breakthrough privacy and performance. Additional modules include Klave for AI (Private RAGs, SMCP for enterprise AI agents), Confidential Computing infrastructure, and solutions like Secure PII Processing, DORA Compliance, Secure Tokenisation, and the Amlytic financial crime analytics platform developed with FutureFlow. The platform is complemented by a marketplace with template libraries for key management, tokenisation, and custody. Secretarium's technology is trusted by Thales, Bank of England, Société Générale, and other leading institutions.
