DLP Regex Advanced Filter regex case-sensitive settings

Hi all, thanks for reading.

 

I'm using Entity advanced filter options to remove false positives caused by a regex.

The problem I'm observing is it seems the case-sensitive option set in the upper part of the config dialog does not apply to the regex defined as filters.

 

** Please check the attached picture as a dummy example of the issue I'm facing.

Attached Example: The entity is set as case-sensitive. The filter is supposed to exclude any string not starting by 3 lower-case letters ([a-z]{3}). The observed behaviour is excluding strings not starting by 3 letters ([a-zA-Z]{3}) though, like it was case-insensitive (ignoring the setting above).

 

Could you please confirm the regex defined as filters are hardcoded as case-insensitive?
If so, is it planned to change this behaviour?

 

Thanks in advance,

Òscar

I'm not aware of any case sensitive/insensitive limitations, but I'm checking with ENG to see.

Hello @jason , I hope you are well.

 

Were you able to get confirmation about it? I need to differentiate between upper and lower case letters but I don't know how to make it.

 

Thanks in advance,

Òscar
