41.3 Exclude List Screen
There may be privacy and legality issues regarding inspecting a user's encrypted session. The legal issues
may vary by locale, so it's important to check with your legal department to make sure that it’s OK to
intercept SSL traffic from your Zyxel Device users.
To ensure individual privacy and meet legal requirements, you can configure an exclusion list to exclude
matching sessions to destination servers. This traffic is not intercepted and is passed through
uninspected.
