Does Azure Files support SMB signing / signatures ? Thanks!

Yes. Since SMB singing is a security mechanism in the SMB protocol, it is available in the Azure Files.

You can read more about the Azure Files SMB security settings from the below link

For clarity, the Azure Files Documentation list out the features that are not supported in SMB File Share in Azure Files. Review the link below to see unsupported features.

@Josh N. Fay Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

Yes, Azure Files support SMB Signing. SMB signing is a security mechanism in the SMB protocol and is designed to prevent man-in-the-middle attacks. When SMB signing is enabled, the client and server negotiate a session key that is used to sign all SMB packets exchanged during the session. Learn more here

You can check and enable SMB signing if not already enabled.
