I would like to announce the Early Availability of WSA 5.x and iWSA 5.x.  Starting today, Barracuda customers have access to this release via Barracuda Cloud Control, navigate to Support > Downloads. Next select Barracuda Web Security from the drop-down list, you will see your download on the right pane. You can click here to be taken to the login page.


WSA version 5 introduces some exciting improvements and features that bring remote filtering into the next generation. Both WSA and iWSA now support client side SSL inspection in PLO mode, this means no longer needing to backhaul traffic to the WSG for SSL traffic control. To utilize these advanced features customers must be running either version 11.0 or 12.0 branch of WSG firmware. Also WSA version 5.x and iWSA 5.x no longer support connection either Classic Web Security Service also known as Flex, nor our current Web Security Service (powered by Zscaler). WSA supports Windows versions 7 and above and iWSA supports MacOS 10.9 and above.


If you would like to provide any feedback or have further questions, please email mailto:WSA-BETA-TESTERS@barracuda.com


Release notes are available here for PC and here for Mac , however below are some highlights.



What's New in Version 5.0 (Early Release)

To download the Barracuda WSA, visit https://login.barrac...port/downloads/. Select Barracuda Web Security from the drop down section, and download the Barracuda Web Security Agent.

  • Client-side SSL inspection - Configured on the Barracuda Web Security Gateway, client-side SSL inspection offloads this processing-intensive feature to the client machine, resulting in improved overall performance of the Barracuda Web Security Gateway. See file://///techlib/display/BWFv60/Client-side+SSL+inspection+with+the+Barracuda+WSA for details. This feature requires running the Barracuda Web Security Gateway version 12.0 or higher.
  • Enhanced authentication mechanism with the Barracuda Web Security Gateway - The Barracuda WSA can use certificates you create on, or upload to, the Barracuda Web Security Gateway to verify the identity of the Barracuda Web Security Gateway and ensure that administrative traffic (configuration, policy requests, and logging) is encrypted, both on the local intranet and when roaming on untrusted networks. See file://///techlib/display/WSA/Authentication+with+the+Barracuda+Web+Security+Gateway+and+the+Barracuda+WSA for details. This feature requires running the Barracuda Web Security Gateway version 12.0 or higher.
  • The Barracuda Web Security Service is not supported for the Barracuda WSA 5.x and above.
  • The Tamper Protection/Watchdog feature is not supported with the Barracuda WSA 5.x and above.
