 The :ref:`nrf_security` acts as an orchestrator for the different cryptographic libraries available in the system.
 These libraries include the binary versions of accelerated cryptographic libraries listed in :ref:`nrfxlib:crypto`, and the open source Mbed TLS implementation in |NCS| located in `sdk-mbedtls`_.
 
-The Kconfig option :kconfig:option:`CONFIG_NRF_SECURITY` prioritizes the usage of the accelerated libraries by default when this is supported by the platform.
+HW accelerated libraries are prioritized over SW libraries when both are enabled.
 For more information about the configuration and usage of the :ref:`nrf_security`, see the :ref:`nrf_security_config` page.
 
 See also :ref:`crypto_samples` for examples of how to configure and perform different cryptographic operations in the |NCS|.
