Is the Cisco Umbrella being discontinued?

I've been hearing rumors that Cisco Umbrella, a popular security solution for networks, is being discontinued. Can you confirm whether this is true? If so, what are the reasons behind this decision? What will be the alternatives for businesses who rely on Cisco Umbrella for their security needs? Additionally, what kind of support and migration options will Cisco offer to its customers who are currently using Umbrella? I would appreciate a clear and concise response to these questions.
