Why am I experiencing latency with the Cisco Secure Client Secure Web Gateway (SWG)?

Note: Cisco announced the End-of-Life of Cisco AnyConnect in 2023 and the Umbrella Roaming Client in 2024. Many Cisco Umbrella customers are already benefiting from migrating to Cisco Secure Client, and you are encouraged to begin migration as soon as possible to get a better roaming experience.

Introduction

The purpose of this article is to define what is the expectation of throughput one would expect to get when using Cisco Secure Client (CSC) (formerly AnyConnect) Secure Web Gateway (SWG).

Expectations

In most cases, there should be no noticeable latency from using Cisco Umbrella SWG, and our peering relationships offset and often accelerate the web experience. If the SWG web experience is not acceptable, please contact Cisco Umbrella Support (umbrella-support@cisco.com) so that we can investigate and troubleshoot specific issues. Since many factors can affect experience, our aim when we troubleshoot a connection is to investigate every part of the path to see if it can be optimized.  

Procedures

Please reach out to Cisco Umbrella Support for assistance. We may ask for additional details including:

• Output from the SWG diagnostic tool. 
• Policy debug
