- OpenTitan is the first commercially deployed open source silicon root of trust
- Chromebooks with OpenTitan include Dell Chromebook 11 CC11260 and 2-in-1 models
- The open source model allows for shared maintenance and retention of expertise between organizations
Google has begun shipping commercially available Chromebooks that feature OpenTitan, the first open source silicon root of trust.
Early devices featuring OpenTitan include the Dell Chromebook 11 CC11260 and Dell Chromebook 11 CC11260 2-in-1, but more will likely follow.
OpenTitan is a major milestone for open source hardware, providing a design that can be reviewed, audited, and maintained by multiple organizations simultaneously.

First commercial devices with OpenTitan
OpenTitan has been in development for seven years as a collaboration between industry partners, academia and the open source hardware community.
This platform aims to develop security silicon designed to meet the reliability and verification standards required for commercial devices.
Google previously announced that manufacturing of OpenTitan silicon was carried out by Nuvoton Technology Corporation, confirming that production quality had been achieved.
The project’s open model aims to provide benefits such as shared maintenance responsibilities, retention of expertise between organizations and engagement in academic research.
The integration of OpenTitan into Chromebooks indicates that Google intends to expand its use of open source security beyond consumer devices.
Plans are already in the works for deployment in Google data centers in 2026, perhaps indicating that the company is trying to align hardware-level trust with broader infrastructure security.
Intellectual property developed through OpenTitan is also being reused in other projects, such as Caliptra, showing that the technology will serve multiple applications rather than just one product line.
There are also plans to develop OpenTitan into a second generation, including post-quantum lattice-based cryptography features and other updates.
While the timeline and full capabilities of these features are not fully specified, they suggest that the project is intended to remain forward-looking and adapt to emerging security threats.
Despite the apparent progress, questions remain about OpenTitan’s performance in large-scale production and real-world conditions.
For now, the implementation of open source silicon in consumer Chromebooks is limited to a small number of models. Its impact on the security of Pixel devices or other products has therefore not yet been demonstrated.
For Google, this marks an important milestone in the development of open source security silicon, although independent verification of its performance and reliability is not yet available.
Therefore, it remains unclear whether silicon can consistently meet the standards expected of data center security hardware.
