This is not something Jamf Pro can do as this ask falls well outside of the domain of device management, and is a Security need. Look in to DLP and Network security tools like Forcepoint, Netscape, Sentinel One and Zscaler; all of these tools can do what you are asking.

We already have Zscaler in our org, can you give me any idea or doc how to achieve this in zscaler.

I recommend taking that ask to Zscaler's community board or opening a case with Zscaler as it's a bit out of band for Jamf Nation. Googling "block SFTP and FTP with zscaler" brings up this page which seems relevant and may get you started. 

For DMG's you either would want to block them on the download with Zscaler or use a DLP tool to prevent them from mounting.
