What Is Data Mapping?
Organizations across industries — from financial services to healthcare to retail to government and beyond — sit on mountains of data, much of which is sensitive, personal, and highly regulated. Sensitive data may be siloed, come from unstructured sources, live in legacy databases, or present other challenges that stand in the way of effective data identification and data mapping.
For any data migration, data integration, or data management process, it is crucial that organizations efficiently map their data — or extract data from source files and transfer it to destination files — across various data systems while ensuring accuracy, completeness, and quality.
Data that has been mapped from one system to another must be accessible and usable for data professionals in governance, privacy, and security. These teams need to be able to rely on accurate data mapping at scale to:
- identify and protect sensitive, regulated, and high-risk data — wherever it exists
- generate a single, accurate, reliable data inventory that covers all types of data — on-prem and in the cloud
- agree upon and collaboratively utilize an accessible, single source of truth across the organization
- manage data processes like file access permissions, data lineage flows, data retention, data remediation, etc.
- identify risk in how sensitive data is handled
- produce relevant insights that drive business value, and more.
You can’t protect what you don’t know you have — and can’t find.
Challenges of Data Mapping
While the importance of data mapping is hardly a new concept for businesses, the complexity and volume of the data that organizations collect, process, and maintain is growing faster than the adoption of best practices. Even as data mapping becomes increasingly crucial to drive business processes and insights, enterprises still struggle to efficiently, accurately, and scalably generate data maps that can also be easily managed.
Organizations face the absolute necessity of shifting manual mapping processes to automated solutions. Automated data mapping software is required for companies to maintain the increasingly large, labyrinthian data sets they manage.
With this enormous influx of personal and sensitive information — which exponentially grows year over year — enterprises can no longer support the time and resources necessary for manual mapping strategies, nor can they afford the risk associated with the outdated data these processes produce.
Data Mapping for Privacy and Compliance
Privacy regulations like the EU’s General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), the Health Insurance Portability and Accountability Act (HIPAA) for healthcare, the Gramm–Leach–Bliley Act (GLBA) for finance, and a growing list of other U.S. and global laws, require that organizations safeguard their sensitive data — whether they define that data as “personal information,” “private information,” “protected health information,” “nonpublic personal information,” or any other type.
What all this data has in common is that it can be tied directly to an individual — and potentially cause harm if it falls into the wrong hands. Effective data mapping helps organizations accurately connect personal, sensitive, confidential, and all regulated data to individuals — so they can know not only what data they have, but who that data belongs to. This visibility allows organizations to enact measures to protect that information while deriving insights from it and meeting regulatory compliance.
Privacy regulations also give data subjects rights over their data by supporting data subject access requests (DSARs), deletion requests, and other requests for information that individuals have the right to obtain from an organization that handles their data. Companies that implement effective data mapping tools can identify data subject records faster — and better respond to DSAR requirements in a timely fashion that meets compliance, maintains customer trust, and supports data privacy best practices across the organization.
Data Mapping Best Practices
Discover Your Data
Start with the data first, implementing a deep data discovery foundation for all your enterprise data — personal, sensitive, regulated, and high-risk data that your organization collects, retains, shares, and processes. BigID automatically finds, maps, classifies, and cleans up all of that data — constantly finding relationships, adding context, and uncovering dark data.
Scan Over Survey
Manual mapping requires that organizations rely on survey-based methods of inventorying data. This outdated technique assumes that stakeholders have a nearly perfect understanding of their data — an assumption that creates inevitable gaps and inaccuracies. BigID’s automated, scan-based discovery and classification techniques generate accurate data maps using auditable scans; support adaptability, modification, and DSARs; and validate any existing survey-based maps.
Classify Data with ML-Driven Technology
To implement efficient data flow mapping, organizations need to go beyond regular expressions. BigID reimagines data classification with purpose-built technology that leverages not only pattern-based discovery, but ML classification based on NLP and NER; AI insight that is based on deep learning; and patented file analysis classification.
Cover All Your Data — Everywhere
BigID empowers organizations to know their data — all of it, everywhere, across all types, in any language, in the data center or the cloud, at rest or in motion — at petabyte-scale. This includes structured and unstructured data, files and documents, images and mail, Big Data, and more — no matter how siloed, hidden, legacy, or hard-to-find that data might be.
Scale and Extend Across the Enterprise
Data grows exponentially, and organizations need a data mapping solution that can scan, discover, define, classify, and monitor data at scale over time. Data maps are living entities that must dynamically add new data sources, account for new standards, and adapt to changes. BigID scales to your business needs, accommodating changes in requirements, structures, and regulations — and gives intelligent insight into the data at scale.
Data Mapping Software — What You Need
Automated data mapping technology is a critical part of any organization’s privacy, security, and governance program. In an era of exponentially increasing, sprawling, complex data, companies can no longer rely on manual processes to achieve the level accuracy that privacy regulations require.
BigID’s flexible, scalable solution gives organizations full data coverage on all of their sensitive and regulated information — everywhere — and leverages a deep discovery, ML-based foundation so companies of any size can efficiently generate accurate data maps. These maps scale to the organization’s needs, create a unified view for data professionals, help achieve regulatory compliance, and more.
