What is a one sentence summary of your feature request?

Enable DLP with Deep Packet Inspection (DPI) to analyze and block sensitive content inside file attachments in Microsoft Teams, as well as extend DPI support to other instant messaging applications.

Please describe your idea in detail. What is your problem, why do you feel this idea is the best solution, etc.

Currently, when using DLP on Microsoft Teams, the feature can successfully block sensitive information if the content is typed directly in chat, but it does not work when the same content is inside a file attachment. Even though DPI is enabled and the machine/app have been restarted, Teams does not inspect the actual file contents. The only way to block attachments now is by using file type restrictions, which is not an effective substitute. My request is for the vendor to enhance DPI capabilities to analyze the content of file attachments in Teams. Additionally, it would be very useful if DPI coverage could be extended to other popular instant messaging apps (such as Zalo, WhatsApp, and Viber) to ensure comprehensive data protection.

How do you currently solve the challenges you have by not having this feature?

Right now, I can only block file attachments in Teams based on file type, but this does not address the real problem since users can still share sensitive content if it is embedded in a non-restricted file type.

Hi Phuong,

Thank you once again for sharing your idea and for helping us improve.
Your feedback is important, and we’ve carefully reviewed the scenarios you described. Here’s our conclusion:

  1. Microsoft Teams – To ensure we can fully investigate this scenario you described, we kindly ask you to open a ticket in our Netwrix Support Portal. Please provide the exact test scenario, all the necessary details and attach the related logs. This will allow our team to reproduce, investigate the situation and deliver a precise solution.

  2. Viber and Zalo – We will open an internal research task to explore the level of visibility and DPI coverage we can provide for these applications. Once our investigation is complete, we’ll share our findings with you.

  3. WhatsApp – At this time, due to end-to-end encryption it uses, there is unfortunately no feasible way for us to enable this type of coverage. If the situation changes in the future, we will be happy to revisit it.

Please let me know if you need guidance on opening a support ticket.

Kind Regards,
Simona
