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.
