We recommend an E5 license so you can take advantage of the advanced monitoring and reporting capabilities available in Microsoft Defender Advanced Threat Protection (Microsoft Defender ATP). These advanced capabilities aren't available with an E3 license, but you can develop your own monitoring and reporting tools to use in conjunction with ASR rules.
