Microsoft Defender for Key Vault

Microsoft Key Vault is a cloud service for securely storing and accessing secure data like secrets, keys, certificates, and passwords. By compromising this data, attackers may be able to gain unauthorized access or perform lateral movement to breach other resources in the customers' environment. 


Microsoft Defender for Key Vault is an Azure-native threat protection service, which detects unusual and potentially harmful access to Key Vault accounts. It provides an additional layer of security intelligence for the keys, secrets and certificates stored in the Microsoft Key Vault by alerting you to suspicious or malicious access. This layer of security allows you to address threats without being a security expert, and without the need to manage third-party security monitoring systems. 


When anomalous activities occur, Microsoft Defender for Key Vault shows alerts and optionally sends them via email to relevant members of your organization. These alerts include the details of suspicious activity and recommendations on how to investigate and remediate the threats.
