Hello Team,
Good Day !
After Cloneed our two version of Hardware ( STM32F3 Series based ) by compititor , we are now more focused on Hardware Security aspects.
Can you Pls Suggest which STM32 MCU is the MOST Secure among all available MCU ? Considering Firmware Protection / physical Attacks ?
I would appriciate , if Higher Level Architecture with Device name is Provided.
We are also open for Paid Consultancy if any 3rd party ready to help...
Regards ,

Hello @bsuthar ,
I'd suggest to try the reading the Introduction to security for STM32 MCUs - Application note first. The AN also includes tables comparing the security features found in different STM32 series.
Of the series on the market, I'd probably suggest the STM32H5 (crypto line) as the most secure. But the security is only working if the application uses all the security features correctly.
