State-of-the-Art Hardware Security

Espressif SoCs with Xtensa® and RISC-V equipped with advanced security features that form the trusted foundation of every device. With capabilities such as Secure Boot, External Memory Encryption, Digital Signature Peripheral, Cryptographic Accelerators, Memory Protection, and Hardware Isolation, the platform offers resilient protection against physical and remote attacks. These features are built using industry-standard cryptographic algorithms, helping customers meet the strict requirements of compliance and trust.

Secure Communication Across All Wireless Protocols

Espressif’s SDK ensures encrypted and authenticated communication over Wi-Fi, Bluetooth, and Thread. With support for Transport Layer Security (TLS) and secure provisioning mechanisms, devices can safely communicate with cloud services and other network peers. This comprehensive network security model guards against eavesdropping, spoofing, and data manipulation across all supported protocols.

Seamless Software Integration

Espressif provides fully integrated software components for securing every stage of the device lifecycle — including Secure OTA updates, Secure Network Provisioning, Encrypted Storage, and Secure Control APIs. These features are tightly coupled with the ESP-IDF and simplify the path to certification, compliance, and zero-trust architecture adoption for connected products.

Hardware-Enforced Trusted Execution Environment (ESP-TEE)

Espressif's Trusted Execution Environment (ESP-TEE) exclusively supported for RISC-V architecture, allows critical operations — such as cryptographic processing, key management, and secure APIs — to run in an isolated hardware-backed zone, fully separated from the main application. This secure enclave ensures that even if application-level code is compromised, sensitive tasks remain protected, enabling secure-by-design AIoT deployments.

Trusted Factory Provisioning with Customer-Controlled Keys

Espressif offers secure manufacturing flows that allow each device to be provisioned with a unique cryptographic identity, enabling seamless, certificate-based onboarding to major IoT cloud platforms.

Customers can choose between CA-based provisioning—where Espressif injects signed X.509 certificates—or self-managed provisioning, where device credentials are created and signed using secure hardware like HSMs or secure tokens. These signed credentials are securely transferred to Espressif for flashing without exposing private keys. This flexible approach gives customers full control over their root of trust while leveraging Espressif’s secure, high-volume manufacturing infrastructure.

End-to-End Product Security Lifecycle Support

Espressif enables long-term product security through tools and processes like SBOM generation, vulnerability analysis, and CVE tracking. A dedicated incident response process ensures prompt attention to reported issues. These mechanisms help product makers remain compliant with evolving global security regulations while maintaining a strong security posture across the entire product lifecycle.
