Hope someone can help. I’m a Sys admin for a company and we’ve just bought a DLP system that I’m trying to create a custom template for. It uses Regex for the expression to search for in the data. I’m after stopping anyone sending out our user Ids.
The user ids are 8 numeric long and always begin with a 5. I’m trying to create a regex for a number beginning with 5 and 7 other numbers after it (e.g. 56784356). I’ve tried from examples and I can get the general jist of it searching for a number but not one that has to begin with a certain number.
Can anyone please help?
