In 2023 Microsoft introduced CHERIoT,<ref name="cheriot"/> a [[RISC-V]] CHERI adaptation optimised for small embedded devices. CHERIoT incorporated ideas from Cornucopia and memory colouring techniques such as SPARC ADI and Arm MTE to enhance security. As part of the UKRI-funded Sunburst project, lowRISC launched the Sonata platform to advance RISC-V-based CHERI development and support standardisation efforts. Both the CHERI RISC-V research work and CHERIoT fed into the standardisation process for an official CHERI family of RISC-V extensions.<ref name=":2">{{cite web |title=CHERI Ratification Plan |url=https://lf-riscv.atlassian.net/wiki/spaces/CTXX/pages/47022116/CHERI+Ratification+Plan |access-date=10 January 2025}}</ref> [[Codasip]] announced that they had RISC-V IP cores with CHERI extensions available to license.<ref>{{cite web |url=https://www.eenewseurope.com/en/codasip-delivers-first-commercial-cheri-processor-using-risc-v/ |publisher=eeNews |access-date=20 January 2025 |title=Codasip delivers first commercial CHERI processor using RISC-V |date=2 November 2023}}</ref>
 
The CHERI Alliance was launched in 2024.<ref>{{Cite web |last=Flaherty |first=Nick |date=2024-11-12 |title=CHERI builds global chip security alliance |url=https://www.eenewseurope.com/en/cheri-builds-global-chip-security-alliance/ |access-date=2025-07-22 |website=eeNews Europe |language=en-US}}</ref> This non-profit organisation was formed by a number of high-tech companies to accelerate CHERI adoption. It provides a platform for collaboration and helps the technology become more visible and easier to use. Its goal is to aggregate the ecosystem and welcomes members interested in CHERI, from commercial companies to universities, research centres, and open-source communities. It is organised in working groups<ref>{{Cite web |title=CHERI Alliance – Working Groups |url=https://cheri-alliance.org/who-we-are/working-groups/ |access-date=2025-07-22 |website=CHERI Alliance |language=en-US}}</ref> that focus on specific themes (operating systems porting, tools, design recommendations...). It also organises conferences focused on CHERI<ref>{{Cite web |title=CHERI Alliance – Events |url=https://cheri-alliance.org/events/ |access-date=2025-07-22 |website=CHERI Alliance |language=en-US}}</ref> and participates to a number of events to promote the technology.
