Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

Please note that Azure Storage Account is a storage PaaS service. It has very limited capabilities to process the files you upload.

You should process the files either

• Before uploading using your application code
• Or
• After uploading by using Azure functions (in case the upload is done by external third party customers)
• Even in this case, you must implement your own logic to validate if the file is considered "Password protected file", and delete them.

Also, "Password protected file" covers a wide area of files and there is no standard on what can be considered as a Password protected file.

• i.e., a .pfx file will mostly be password protected.
• But the same cannot be said for a file with extension .pdf.
• It can be either password protected or not

Trigger for blob upload : Azure Blob storage trigger
