Unable to block download and upload for chatgpt and messengers

Hi Friends,

Recently i am trying to acheive an requirement where i want to allow messenger and chatgpt in my network but files uploading and downloading should be blocked.

I tried configuring decryption and flie blocking profiles along with two seperate policies blocking chatgpt-base and messenger-base applications.

I am able to decrypt the traffic and in messenger app one way like uploading files is not working but downloading is happening where as for chatgpt both upload and download is not working.

Not sure where i am missing out but if you have ever tried this and were able to implement it successfully would like to have your inputs and guidance on how to acheive it.

Looking forward for your responses.

Regards

Satya Kalyan

Hello,

Check out if the application is in the Palo Alto. In the case of ChatGPT there looks to be a app for uploading. If you setup a security policy above your allow policy to deny the traffic, this should work.

If there is not an application option, then you are stuck.

To follow up on OtakarKlier response, I checked the applipedia on the fw and it looks like dalle(image generator) counts as option for downloading/uploading. However for files like pdfs, documents, it seems there isn't an option for that.
