Dynamic Data Masking performance overhead
-

Question
I'm thinking of using the new dynamic data masking that has been introduced with SQL Server 2016 as part of our GDPR project . Does anyone else have experience of it? I am particularly interested if there is a performance overheard.
Solution
No, there is no overhead involved (not heard of any yet). I have used it in my Azure SQL Database and works like a charm.
Data Masking is a quick solution for data security as you can control the users who can view the data, but on a broader aspect this cannot be the sole security solution.
