Seems some of our customers are trying to slow down youtube, facebook etc. without SSL decryption.
The confusing part is in the logs these show up as youtube-base, facebook-base etc but only sometimes and then other times they show up as SSL.
So is using the QoS feature pointless without performing SSL decryption first?

Not completely, but it's also not really that effective. As you've stated without decryption the firewall does application identification based off of what it can actually see, if you aren't decrypting traffic this ability is limited. Generally if someone is trying to rate limit specific applications it would be advisable to explain that there will only be limited success, and if they aren't willing to enable decryption you can't fully accomplish this task.

But at the same time once decryption is available the firewall can succesfully achieve rate limiting most apps like youtube and facebook, right?
