If you are looking for a way to identify or mask the Personally Identifiable (PI) information in your data, then this post is for you.

PI data is a type of sensitive data that can be leveraged to identify a specific person. This data can be present in form of your name, contact number, age, DOB, address, etc. These days with the technological advancements, this PI data can also be information related to your computer or smartphones like IP address, MAC address, IMEI number, etc.

The handling of such sensitive data is always performed in a 2 step process.

  1. Identify the PI data present in your database
  2. Handle the PI data by a technique most suited in your case

There are different ways to handle the sensitive data like removing them or replacing them with some other characters or encrypting and then later decrypting them.

Now, what if I tell you that all this can be taken care of by one single service? That would be great, right? Cloud Data Loss Prevention (DLP) is your answer. From identifying the sensitive data to masking or redacting it from the main file or even encrypting it with a key, it can do all the types of data-related security tasks that you want to take care of. It can detect any sensitive information and then perform the desired operation on it…
