Hello everyone,
Recently, I have been experiencing some issues for having HTTPS scanning/decrypting active in the rules on my network.
For some reason, when I try to access some websites I got a Sophos block message saying that the certificate its invalid.
I thought that was related to the fact that the certificate didn't have an owner name, something like this:
Then, I've found another website with a similar certificate but this time I didn't get any issue.
So, its not really clear for me, what is the condition to say that a certificate its invalid? How can I explain this behaviour to my boss?
I have the "Block invalid certiticates" option marked on the firewall but I want to know what is happening before I decide to change something.
