This article deals with E-Series Hardware appliances and Virtual Machines, for details about F-Series Sizing please go to Sizing Guide for Forward Proxy Scenarios — Skyhigh Security Web Gateway Version 11.2.7 on the WBG-5000-F and WBG-5500-F Appliances

When running a Secure Web Gateway appliance, you need to consider how to configure the sizing options based on the amount of web traffic that you plan to process using the appliance.

In the following, some recommendations for sizing a physical or virtual appliance are provided. For more details, ask your Skyhigh Security channel sales engineer or representative.

The recommendations assume that you are running Secure Web Gateway 11.2 or a higher version on your appliance.

Notes

¹ With hyper-threading enabled

² The recommended sizes have been tested for running Secure Web Gateway appliances as a virtual machines
(VMs) on Intel (R) Xeon (R) CPU E5-2680 at 2.80 GHz or higher with Hyper-V and VMware ESX.

³ Security features enabled on an appliance impact throughput and must be considered for the sizing.

⁴ The maximum number of simultaneous connections can vary depending on the appliance model, the web policy
that is enforced under Secure Web Gateway, and the filtering workload.

Recommendations for Sizing the Web and User Parameters When Performing Anti-malware and URL Filtering

Web Traffic (Requests/s)	182	698	1261	120	240
Employee Count (Number of Users)	1820	6980	12610	1200	2400

Recommendations for Sizing the Web and User Parameters When Only Performing URL Filtering

	WBG-4500-E	WBG-5000-E	WBG-5500-E	VM-8	VM-16
Internet Bandwidth (in MB/s)	88	343	403	51	102
