- **Virtualization-based security** Windows NTLM and Kerberos derived credentials and other secrets run in a protected environment that is isolated from the running operating system. - **Virtualization-based security** Windows NTLM and Kerberos derived credentials and other secrets run in a protected environment that is isolated from the running operating system.
- **Better protection against advanced persistent threats** When Credential Manager domain credentials, NTLM, and Kerberos derived credentials are protected using virtualization-based security, the credential theft attack techniques and tools used in many targeted attacks are blocked. Malware running in the operating system with administrative privileges cannot extract secrets that are protected by virtualization-based security. While Credential Guard is a powerful mitigation, persistent threat attacks will likely shift to new attack techniques and you should also incorporate Device Guard and other security strategies and architectures. ,- **Better protection against advanced persistent threats** When Credential Manager domain credentials, NTLM, and Kerberos derived credentials are protected using virtualization-based security, the credential theft attack techniques and tools used in many targeted attacks are blocked.
