A Security and Privacy Focused Phone
The Librem 5—by Purism—is the most secure phone available today for a long list of competitive reasons. The Librem 5 separates the cellular modem from the main CPU and memory, that physical isolation is critical to securing the rest of the phone, operating system, storage, and memory from the cellular carrier firmware and towers. The Librem 5 also offers hardware kill switches that physically sever the circuit to Cellular with the first switch, WiFi/BT with the second, and Camera/Microphone with the third, it even offers Lockdown mode when all three switches are turned off. Keeping all the radios separate from the CPU and memory means the ultimate security by hardware isolation.
Security by Design
The Librem 5 is completely designed and built in-house at Purism, from the schematics, chip selection, design, manufacturing, assembly, operating system, kernel development, applications, fulfillment and support. Or for one-level of secure supply chain hardening consider the Librem 5 USA, where the electronics are manufactured in Purism’s United States facility, you have the most secure phone available.
Source Code Fully Auditable
Security is only as good as the ability to verify that security. If you don’t have access to the source code, you cannot verify any security claims. This is why it is industry-wide understood that to have the best security you must be able to verify and audit the source code. Purism’s Social Purpose Company status and Articles of Incorporation require this to be true and continue to be true, PureOS as an operating system releases all source code.
