What is Data Discovery?

Enterprises are amassing colossal volumes of sensitive data - structured and unstructured - across an increasingly complex web of legacy on-premises systems, cloud platforms, and third-party SaaS applications. This data is proliferating at breakneck speed, often being replicated and shared with external AI-driven tools without organizations even realizing it.

Compounding the problem is the ever-evolving scope of what qualifies as sensitive data. As it powers more business processes and functions, most enterprises find it nearly impossible to pinpoint exactly where their data resides or how it’s used. These blind spots pose urgent risks ranging from falling out of compliance with stringent regulations like GDPR and PIPEDA to exposing valuable information to breaches.

Faced with this escalating crisis, enterprises are recognizing that data discovery can no longer be postponed. It is the critical, immediate step for regaining control over a dangerously fragmented data landscape.

What is Data Discovery?

‍

Data discovery provides organizations with the ability to comprehensively locate and map their data assets across all repositories, whether on-premises, in the cloud, or associated with shadow IT systems. It ensures that sensitive information is found and identified across both structured databases and unstructured sources like documents or emails.

By leveraging advanced technologies like contextual awareness and named-entity recognition, more innovative data discovery solutions not only locate sensitive data across structured and unstructured sources but also intelligently analyze its context to determine its nature.

These tools examine the data to accurately classify sensitive information, such as personal identifiers or financial records, with high confidence. This approach minimizes false positives, freeing organizations to focus on truly critical data without being overwhelmed or distracted by irrelevant results or misclassifications.

It also equips organizations with a high degree of awareness about how their sensitive data is being used. They can quickly flag whether customer data is being used in third-party apps and, in turn, start building internal controls to secure that data with tokenization or data masking.

‍

Why is Data Discovery Important

‍

Data Resides in More Places, Often With Fewer Controls

‍

The rapid proliferation of data across diverse environments has made it increasingly difficult for enterprises to maintain control over their sensitive information. 

Data is now generally stored in a wide range of locations, including legacy systems, shadow IT repositories, third-party SaaS platforms, and cloud environments, often without proper oversight or security measures.

This lack of visibility and control creates vulnerabilities, as organizations struggle to identify where sensitive data resides and whether it is adequately protected. Without data discovery capabilities, enterprises risk leaving critical gaps in their security posture, exposing themselves to regulatory non-compliance and potential breaches.

Data discovery provides the ability to locate and inventory data across all repositories, be it structured or unstructured, eliminating blind spots in the organization’s data landscape.

‍

Data is Being Used Across More Processes

‍

As enterprises increasingly integrate data into their operations, sensitive information is being leveraged across a growing number of processes and workflows. 

From customer service platforms to financial systems and supply chain management tools, data drives decision-making and operational efficiency. 

However, this widespread usage amplifies the risk of mishandling or misclassifying sensitive information, especially when processes span multiple systems, involve automated workflows, or extend to third-parties. 

Data discovery is critical in this context because it enables organizations to identify not only where their data resides but also how it is being used. 

By understanding the flow of sensitive information across processes, enterprises can implement targeted controls to ensure compliance and safeguard against unauthorized access or misuse.

‍

Data is Being Shared With AI and Other External Systems

‍

The adoption of AI-driven tools and external integrations has introduced new risks to enterprise data security. Sensitive information is often shared with AI tools for analysis or decision-making purposes, as well as with external vendors or platforms for operational needs.

These interactions can lead to unintended replication or exposure of critical data if proper safeguards are not in place. Furthermore, AI systems may inadvertently process sensitive information without appropriate controls, increasing the risk of non-compliance with privacy regulations like GDPR or PIPEDA.

Data discovery plays a pivotal role in mitigating these risks by identifying where sensitive data is being shared and ensuring that it is classified correctly before being accessed by external systems. This proactive approach helps enterprises maintain control over their information while leveraging advanced technologies responsibly.

‍

Data Discovery Methods

‍

Manual

‍

Manual data discovery is a traditional approach where individuals or teams manually identify and catalog data across an organization’s systems. This method typically involves physically reviewing databases, file systems, and repositories to locate and classify sensitive information. 

While it can be effective in very small, controlled environments, manual discovery becomes impractical as the volume, variety, and complexity of data increase. It is time-consuming, prone to human error, and often fails to uncover hidden or unknown data sources, such as those in shadow IT or legacy systems. 

Furthermore, manual methods lack the scalability needed to address modern challenges like unstructured data or dispersed cloud environments. Despite these limitations, manual discovery can still play a role in supporting automated processes by providing human oversight for specific tasks or validating automated results.

‍

Automated

‍

Automated data discovery leverages advanced technologies and tools to locate and classify sensitive data across structured and unstructured repositories with speed and precision.

Unlike manual methods, automated solutions can scan vast amounts of data across on-premises systems, cloud platforms, shadow IT environments, and third-party SaaS applications without requiring prior knowledge of their locations.

These tools use techniques like named-entity recognition and contextual awareness to intelligently classify data while minimizing false positives. 

Automated discovery is essential for keeping pace with the growing complexity of enterprise data landscapes, ensuring no blind spots remain.

Additionally, modern solutions are designed for ease of deployment, requiring no code changes or disruptions to existing workflows, making them highly scalable and efficient for organizations aiming to strengthen their security posture and meet compliance mandates.

How to Fully Benefit From the Data Discovery Process

‍

Accelerate with Automation

‍

To accelerate the data discovery process and ensure it delivers meaningful results, enterprise organizations must adopt automated solutions capable of scanning and identifying data across all environments, including legacy systems, cloud platforms, and shadow IT repositories.

Modern data discovery tools, such as DataStealth’s platform, leverage advanced technologies like named-entity recognition and contextual awareness to locate and classify sensitive data with precision, minimizing false positives. 

This automation not only speeds up the discovery process but also ensures comprehensive visibility into both structured and unstructured data sources.

Furthermore, deploying solutions that require minimal disruption, such as those with no-code or DNS-based implementations, enables enterprises to integrate data discovery seamlessly into their existing workflows without compromising operational efficiency or imposing expensive staff re-training.

‍

Build on Data Discovery With Data Security

‍

While data discovery is a critical first step, its value is significantly amplified when integrated with robust data security measures like tokenization, which replaces sensitive data with substitute values that hold no exploitable value, ensuring that even if a breach occurs, attackers cannot access or leverage the original data.

Identifying sensitive data is only part of the equation; protecting it is equally important. For example, once sensitive customer data is discovered and classified through a solution like DataStealth’s Data Discovery and Classification, data tokenization can be implemented to protect it both at rest and in transit. 

This combined approach not only strengthens compliance efforts by safeguarding regulated data but also reduces the risk of exposure in today’s threat landscape. 

By integrating these processes, enterprises can maintain operational processes reliant on sensitive data while ensuring it remains secure across all environments, be it on-premises, in the cloud, or shared with external systems like AI platforms.

‍

Align Protection Policies with Risk Thresholds

‍

A robust data discovery system must not only identify sensitive information but also provide clarity on the certainty of its findings. This is where confidence scoring becomes critical, a tool or mechanism that quantifies the accuracy of the data classification results, enabling organizations to align protection policies with their unique risk thresholds.

For example, a Social Insurance Number (SIN) found in a payroll database receives a high-confidence score due to its structured format and contextual relevance. The same SIN buried in an unrelated document might receive a lower score, prompting further review before applying stringent controls.

This layered approach minimizes false positives while ensuring high-confidence classifications are prioritized for immediate action. DataStealth’s solution employs contextual awareness and validity scoring alongside named-entity recognition to evaluate how likely a detected data element truly matches sensitive criteria.
