What are Sensitive Data Discovery Tools for Windows?

Sensitive data discovery tools are software solutions designed to help organizations identify, classify, and protect sensitive information across their data environments. These tools scan databases, file systems, cloud storage, and applications to locate sensitive data such as personally identifiable information (PII), financial records, healthcare data, or intellectual property. By using advanced algorithms and pattern recognition, sensitive data discovery tools can automatically flag data that is at risk of exposure or non-compliance with regulations such as GDPR, HIPAA, or CCPA. They often provide visualization and reporting features, allowing organizations to see where sensitive data resides and assess the level of risk. These tools are crucial for ensuring data security, privacy compliance, and mitigating the risk of data breaches.

Protegrity

Protegrity

Our platform allows businesses to use data—including its application in advanced analytics, machine learning, and AI—to do great things without worrying about putting customers, employees, or intellectual property at risk. The Protegrity Data Protection Platform doesn't just secure data—it simultaneously classifies and discovers data while protecting it. You can't protect what you don't know you have. Our platform first classifies data, allowing users to categorize the type of data that can mostly be in the public domain. With those classifications established, the platform then leverages machine learning algorithms to discover that type of data. Classification and discovery finds the data that needs to be protected. Whether encrypting, tokenizing, or applying privacy methods, the platform secures the data behind the many operational systems that drive the day-to-day functions of business, as well as the analytical systems behind decision-making.
