Client Server SSL Decryption

[Fly_Al]

Hi Folks ;

I have a distributed software on my internal network and everyone is using it. It's like endpoint and it has a server .this server sometimes sends something to the server in the direction of the internet.
I want to look into the data that it sends. I don't know if it is leaking critical information or what.

I opened SSL Decypt and got packet capture from Palo alto but it is full of encrypted fail errors

This is not a website because let me explain simply, the server inside sends a TLS SSL connection to the outside and ports the data, how can I see inside the data posted inside.

There is SSL Decryption on websites and it works, but how can I decrypt a software that communicates Client - Server?

Hello,

You might not be able to. There are some apps that use certificate pining to prevent ssl decryption in the middle, or man-in-the-middle. 

Sorry it doesnt truly answer your question.
