# Microsoft Pluton security processor
Microsoft Pluton security processor is a chip-to-cloud security technology built with [Zero Trust](/security/zero-trust/zero-trust-overview) principles at the core. Microsoft Pluton provides hardware-based root of trust, secure identity, secure attestation, and cryptographic services. Pluton technology is a combination of a secure subsystem which is part of the System on Chip (SoC) and Microsoft authored software that runs on this integrated secure subsystem.

Pluton technology is a combination of a secure subsystem, which is part of the System on Chip (SoC) and Microsoft authored software that runs on this integrated secure subsystem.
Microsoft Pluton is currently available on devices with Ryzen 6000 and Qualcomm Snapdragon® 8cx Gen 3 series processors. Microsoft Pluton can be enabled on devices with Pluton capable processors running Windows 11, version 22H2.
## What is Microsoft Pluton?
Designed by Microsoft and built by silicon partners, Microsoft Pluton is a secure crypto-processor built into the CPU for security at the core to ensure code integrity and the latest protection with updates delivered by Microsoft through Windows Update. Pluton protects credentials, identities, personal data and encryption keys. Information is significantly harder to be removed even if an attacker has installed malware or has complete physical possession of the PC.

Microsoft Pluton is designed to provide the functionality of the Trusted Platform Module as well as deliver other security functionality beyond what is possible with the TPM 2.0 specification, and allows for additional Pluton firmware and OS features to be delivered over time via Windows Update. For more information, see [Microsoft Pluton as TPM](pluton-as-tpm.md).

| **Hardware** | Pluton Security Processor is a secure element tightly integrated into the SoC subsystem. It provides a trusted execution environment while delivering cryptographic services required for protecting sensitive resources and critical items like keys, data, etc. |
| **Firmware** | Microsoft authorized firmware provides required secure features and functionality, and exposes interfaces that operating system software and applications can use to interact with Pluton. The firmware is stored in the flash storage available on the motherboard. When the system boots, the firmware is loaded as a part of Pluton Hardware initialization. During Windows startup, a copy of this firmware (or the latest firmware obtained from Windows Update, if available) is loaded in the operating system.

## Firmware load flow
When the system boots, Pluton hardware initialization is performed by loading the Pluton firmware from the Serial Peripheral Interface (SPI) flash storage available on the motherboard. During Windows startup however, the latest version of the Pluton firmware is used by the operating system. If newer firmware is not available, Windows uses the firmware that was loaded during the hardware initialization. The diagram below illustrates this process:

# Microsoft Pluton as Trusted Platform Module
Microsoft Pluton is designed to provide the functionality of the Trusted Platform Module (TPM) thereby establishing the silicon root of trust. Microsoft Pluton supports the TPM 2.0 industry standard allowing customers to immediately benefit from the enhanced security in Windows features that rely on TPM including BitLocker, Windows Hello, and Windows Defender System Guard.
As with other TPMs, credentials, encryption keys, and other sensitive information cannot be easily extracted from Pluton even if an attacker has installed malware or has complete physical possession of the device. Storing sensitive data like encryption keys securely within the Pluton processor, which is isolated from the rest of the system, helps ensure that emerging attack techniques such as speculative execution cannot access key material.

Pluton also solves the major security challenge of keeping its own root-of-trust firmware up to date across the entire PC ecosystem, by delivering firmware updates from Windows Update. Today customers receive updates to their security firmware from a variety of different sources, which may make it difficult for them to apply these updates.

Devices with Ryzen 6000 and Qualcomm Snapdragon® 8cx Gen 3 series processors are Pluton Capable, however enabling and providing an option to enable Pluton is at the discretion of the device manufacturer. Pluton is supported on these devices and can be enabled from the Unified Extensible Firmware Interface (UEFI) setup options for the device.
UEFI setup options differ from product to product, visit the product website and check for guidance to enable Pluton as TPM.

> If BitLocker is enabled, We recommend disabling BitLocker before changing the TPM configuration to prevent lockouts. After changing TPM configuration, re-enable BitLocker which will then bind the BitLocker keys with the Pluton TPM. Alternatively, save the BitLocker recovery key onto a USB drive.
