Hex Five Security Announces Creation of Strategic Advisory Board

Esteemed Group of RISC-V and Security Leaders to Support Hex Five as Advocates and Ambassadors of MultiZoneTM Security

Redwood Shores, CA – NOVEMBER 1, 2018 – Hex Five Security, Inc, the creator of MultiZone™ Security, the first trusted execution environment for RISC-V, today announced the formation of the Hex Five Strategic Advisory Board, an esteemed group of technical and business leaders chosen to counsel the company on achieving its goal of making RISC-V the most secure processor platform.

Don Barnetson, co-founder of Hex Five Security commented, “With the rapid growth of the RISC-V ecosystem and our initial release of MultiZoneTM Security complete, the time is right to focus on our strategic objective of putting MultiZone™ Security into every RISC-V boot rom.” Hex Five Security’s advisors include:

  • Celeste Cooper is currently the Chief of Staff to the CTO at Western Digital. In her role at Western Digital, Celeste is an active member of the RISC-V Foundation supporting commercialization efforts and the buildout of the RISC-V ecosystem.  Prior to joining Western Digital, Celeste was at Hewlett Packard Enterprise where she held several roles including Vice President of Global Professional Services and Vice President of Strategy & Operations / Chief of Staff for the Communications Solutions Business.   Celeste has also been involved with several startups including her role as the Chief Operating Officer of Runa, Inc.
  • Jon Geater is a cryptographic security industry veteran and globally recognized expert in Trusted Execution Environments. Most recently as Chief Technology Officer for Thales eSecurity, Jon has also held senior global roles in leading companies such as ARM (Director of Technology and Division CTO, Secure Services Division) and TEE specialist Trustonic (founding Chief Technology Officer and Executive Vice President Engineering).  A keen supporter of open standards, Jon has been a board director and chair of the Security Task Force at GlobalPlatform, and currently serves on the Governing Board of the Linux Foundation’s Hyperledger project.
  • Art Swift is Vice-Chair of the RISC-V marketing committee and leads marketing & business development efforts at Esperanto Technologies, a developer of high performance high-performance, energy-efficient computing solutions based on the open standard RISC-V ISA.  He has more than 25 years of executive-level experience in the tech industry, including CEO at low power chip-maker Transmeta, CEO of nanotech innovator Unidym, and vice president of marketing and business development at MIPS, a leading provider of microprocessor IP.

“Security is critical to every application.” said Celeste Cooper.  “The standard RISC-V specification contains the hooks, but MultiZone Security enables designers to implement robust security by default – without requiring new hardware, tools or workflows.”

“We’ve learned so much over the past 20 years of developments in HSM, TPM and TEE, and naturally in some areas we know we could have done better. “ said Jon Geater. “With RISC-V and MultiZone Security, we have a chance to design security in from the start and build a simple, robust security architecture that developers can implement as a part of their everyday workflow.”

“There is a clear market need for Hex-Five’s MultiZone Security.” Said Art Swift.  “Security by separation is a key best practice in the security world, but having just a secure and non-secure zone is not enough. Enabling multiple secure zones without requiring special hardware or deep integration with user code is a breakthrough.”
