Extreme internet speed reduction using Umbrella

[jbergener]

We are deploying Umbrella on our hybird user laptops.  We are seeing internet speed reductions down to 1/10th of actual internet speed on these devices.  We had a user today share screen captures of 2 separate devices (one using Umbrella, one not).  The device not using Umbrella reported internet speed of 300+ Mbps.  The laptop using Umbrella reported 30+ Mbps.  Both were connected to the same wifi network.

I know there is a lot going on behind the scenes with Umbrella but is this normal?

Are you using Umbrella SIG which redirects user traffic via the cloud-delivered firewall? If so, that could be the culprit.

Classic Umbrella - the straight DNS security product - usually results in improved speed of DNS lookup and almost no measurable difference in end user performance.

We are using SIG.  I just wasn't expecting that much of a decrease in overall speed.

The SIG IPsec tunnels are a shared resource of 250 Mbps each. Reference:
