Following on my previous post, I had a look at the performance impact of enabling QVD and QVF encryption in Qlik Sense.
In this test, I’m using Qlik Sense Enterprise November 2019 release on an Azure B4ms (4 vCPU, 16GB RAM) VM running Windows Server 2019. Qlik Sense encryption settings were left at default.
From Qlik Sense Enterprise on Windows September 2019 (the option became configurable via the QMC in November 2019), users have the option of enabling one or both of QVD and QVF encryption – adding at-rest protection from people who shouldn’t have access to your valuable files. This is enabled server-wide and applies to all content on the environment.
The big issue that I see is that any security office is going to require that any and all encryption is enabled – without understanding the issues this could cause.
