Data Theorem is a leading provider in modern application security. Its core mission is to analyze and secure any modern application anytime, anywhere.

We were founded to protect and defend our collective privacy from exploitation. Together, our founders laid the groundwork for a revolutionary new approach to data security in response to advances in quantum computing. Via strategic investments in cutting-edge quantum hardware companies and exclusive partnerships with premier global research institutes and U.S. national labs, we have amassed multiple quantum entropy sources to create high-quality random keys at scale. As a result of this technology and its revolutionary Everlasting Security protocol, we have developed the only cryptographic solution capable of securing information indefinitely with mathematical proof as evidence.

Our CIS ControlsTM and CIS BenchmarksTM are the global standard and recognized best practices for securing IT systems and data against the most pervasive attacks. These proven guidelines are continuously refined and verified by a volunteer, global community of experienced IT professionals. CIS is home to the Multi-State Information Sharing and Analysis Center® (MS-ISAC®), the go-to resource for cyber threat prevention, protection, response, and recovery for U.S. State, Local, Tribal, and Territorial government entities.

The Problem: For 30 years, the industry has relied on dedicated hardware acceleration (like Intel AES-NI) to mask the inefficiency of legacy algorithms. As computing moves off traditional servers and onto diverse ARM and RISC-V edge devices, that hardware crutch is disappearing. Legacy cryptography (AES/SHA) is now too heavy for resource-constrained devices and acts as a massive bottleneck for real-time AI data ingestion. Our Solution: We have engineered the TRV Monolith—a paradigm-shifting, post-quantum cryptographic engine built entirely on our proprietary Boolean Transformation Gate System (BTGS). Built completely in native Rust, the engine operates with deterministic execution behavior, zero dynamic heap allocation, and is 100% dependency-free (no reliance on external libraries). It relies exclusively on symmetric state-transformation and non-linear Boolean Circuit Satisfiability, . This breakthrough allows us to solve three massive market mandates: The IoT & Edge Explosion: Running natively on edge hardware without dangerous compromises or heavy runtimes. The Sovereign Tech Mandate: Providing independent, verifiable cryptographic architectures to escape legacy vendor lock-in. The AI Data Pipeline: Securing massive real-time AI data harnesses without slowing down large language models (LLMs).
