Nowadays, we are facing issues where most public sites hosted on CDNs like Akamai or YouTube are blocking URLs or prompting users to complete challenges, such as "Are you a robot?". I believe this happens because we are using the Cisco Umbrella roaming client, and all users who utilize the roaming client access the internet through the same IP address subnet (155.x.x.x). How can we mitigate these kinds of issues?
