The CHERI Alliance, a global group focused on improving cybersecurity with hardware memory safety technology, has announced a new member—BT Group. As one of the world’s top telecommunications companies, BT brings its deep experience in network security and innovation to the Alliance. This move supports the shared mission of building a safer digital future.
The CHERI Alliance brings together industry leaders, researchers, and governments to promote Capability Hardware Enhanced RISC Instructions (CHERI) technology. This technology is designed to stop memory safety issues, which are a common cause of cyberattacks, by adding hardware-based protections.
BT’s decision to join shows its dedication to staying at the forefront of cybersecurity. The company will share its knowledge in secure communications and network resilience. It will work closely with other members to speed up the adoption of CHERI technology across different industries.
“BT’s leadership in secure communications is unmatched,” said Mike Eftimakis, founding director of the CHERI Alliance. “Their support will help us push for wider use of CHERI technology, making systems safer and more resilient for all.”
Dave Harcourt, BT’s chief security authority and automation director, added, “As a global telecom leader, we know how vital it is to protect the digital systems that power our economy and society. By joining the CHERI Alliance, we can team up with others to explore what’s possible with hardware-enabled cybersecurity.”
The Alliance works through collaborative groups that create tools, open-source software, and guides to help speed up CHERI adoption. It also helps raise awareness of CHERI’s benefits and provides recommendations for building safer products. The British government has named the CHERI Alliance as a partner in efforts to bring CHERI technology into wider use.
Earlier this year, BT urged the U.K.’s critical national infrastructure providers—including sectors like healthcare, energy, emergency services, and local government—to switch off outdated copper landline networks by the end of 2025.
