Security Features

Sennheiser products are built around the needs of our cherished AV and IT professional users. We are continuously evaluating and evolving our products to make sure we offer all essential security features. The following features are gradually rolled out in parts of our portfolio and will be available in all new relevant solutions.

Encryption for Confidentiality

To meet the increasing demand for security in AV and IT projects, Sennheiser developed the secure Sennheiser Sound Control Protocol for secure control of our devices. It is an encrypted REST API allowing the user to control the device using HTTPS commands and integrate products in every IT environment. It offers end-to-end security, utilizing TLS.

Selected wireless microphone products support wireless link encryption, and some also support Dante Media Encryption — both based on AES 256. This encryption standard is recommended by NIST and widely used across industries including AV. Support for Dante Media Encryption will also be extended to our ceiling microphones and TeamConnect Bars in the near future.

Authentication and Authorization for Access Control

Sennheiser implements authenticated methods on our devices and software, to ensure that only authenticated users can access the devices on the network and that devices are secured end-to-end.

Most Sennheiser software solutions which are accessible on the network, are password protected by default.
All the latest Sennheiser devices must be claimed and password protected before allowing configuration or monitoring.
3rd party integrations are disabled by default. They must be explicitly enabled, authorized by the user and authenticated in the 3rd party module.
802.1x is an important industry standard for secure network authentication. It is already available on selected Sennheiser products, and we are extending support across our current portfolio. All future Business Communication products will support 802.1x, enabling IT professionals to configure precisely which devices can communicate on their internal networks.

Firmware updates

All network connected Sennheiser devices are updatable, thus ensuring that future vulnerabilities can be resolved by providing security patches.
The devices utilize a secure firmware update, ensuring that only authorized firmware is executed.
Sennheiser monitors for vulnerabilities and aims to provide security patches in a timely manner. Please always keep your systems up-to-date.

Advanced networking options

Sennheiser provides multiple network ports on our products to allow IT and AV professionals to utilize network isolation. In complex customer networks, the Sennheiser device can be connected to separate networks, isolating control from media communication.

For security sensitive applications and additional flexibility, customers also have the option to use analog audio on selected products and disconnect their devices from the network altogether.

Cloud Security at Sennheiser

DeviceHub is Sennheiser’s cloud-based device management and monitoring platform, providing centralized visibility, configuration, and control from any browser. It helps AV and IT professionals to maintain system reliability, streamline operations, and enable secure collaboration across distributed environments.

The Sennheiser DeviceHub platform is built following security by design principles to ensure the confidentiality, integrity, and availability of your AV infrastructure. Hosted on Microsoft Azure, it leverages enterprise-grade identity controls, encrypted communications, and compliance frameworks to protect user data and device interactions. All communication between users, DeviceHub, and devices uses HTTPS, MQTT and WSS network protocols. The communication is authenticated and encrypted using Transport Layer Security (TLS) version 1.2 or higher. Customer data is encrypted using AES256. All private data processing is done in compliance with GDPR. For more information, please see the Sennheiser DeviceHub Privacy Policy. DeviceHub also complies with NIS2, when it comes into force in Germany in 2026, as well as the Cyber Resilience Act (CRA), when it comes into force in 2027.
