Top 10 Sensitive Data Discovery Tools: Benefits, Work, Challenges

Digital privacy is a must-have. Whether you share your personal and financial details at your bank or make a transaction at a retail store, digitalization has certainly made data security an important part of our lives. 

Access to critical information, such as financial records, personal details, or medical information, can draw an accurate picture of your personal and financial well-being, thus raising concerns. 

So, how do you ensure your sensitive data remains secure and accessible only with your permission? 

Well, this is where sensitive data discovery steps in. Like digital detectives, sensitive data discovery tools uncover hidden information to safeguard privacy. Let’s learn more!

What is Sensitive Data Discovery?

Sensitive data discovery involves identifying sensitive information within a business’s network. They may be found hiding in files, databases, or emails. This process involves using specialized tools and techniques to locate, categorize, and manage sensitive information, ensuring it is properly protected.

How Does Sensitive Data Discovery Work?

Sensitive data refers to important data such as your social security number, credit card information, health records, etc.

These pieces of information are frequently stored on your computer or online in documents, spreadsheets, or databases. Sensitive data discovery tools search these files and databases for patterns and formats that match sensitive data.

For example, upon use, a sensitive data discovery tool raises a red ticket to alarm that you have a document with a string of numbers that matches a credit card number. Similarly, if you have a spreadsheet containing a list of names and medical conditions, the program detects the data's potential sensitivity.

Challenges in Sensitive Data Discovery

Sensitive data discovery is tough. Some sensitive data might be hidden in unexpected locations and in various formats, making it a bit like searching for a needle in a haystack. Moreover, sensitive data discovery is governed and, in some geographies, banned,  which adds to another layer of complexity.

Cybersecurity and data protection experts continuously develop and update sensitive data discovery tools to address these challenges. Let’s explore the top 10 smart sensitive data discovery tools that identify different types of sensitive data.
