Sensitive data, like customer information and internal processes, often lurks hidden in employee devices or unmanaged spreadsheets. This "shadow data" poses a security risk because it's difficult for IT teams to monitor and protect. Without visibility into this hidden data, organizations can't effectively enforce security policies, putting them at risk of data breaches.
Why You Need Data Discovery: The Shadow Data Threat
Hidden data poses risks far beyond unnoticed PII on personal devices. Internal configurations, intellectual property, strategic plans, and other sensitive corporate information are equally vulnerable. Mishandling this data can lead to severe consequences, including hefty fines, reputational damage, and potential legal action.
The Consequences of Mishandling Data
A data breach that exposed the information of 18,000 Nissan customers highlights the dangers of unsecured data. Such incidents can result in:
The Solution: Data Discovery Tools
Data discovery tools offer a solution by scanning extensively to uncover hidden data. This visibility allows DevSecOps teams to secure every piece of data throughout the organization, improving compliance and overall security.
What is Data Discovery?
Data discovery is about getting to know your data better by indexing, profiling, and categorizing it across various sources to create a structured map of all your data assets. It reveals exactly what you have, where it's stored, and how it's organized.
Selecting the Right Data Discovery Tool: Key Criteria
Selecting the right data discovery tool is an investment that goes beyond just finding data. Here’s what you need to consider to make an informed decision:
1. Data Source Compatibility
Does the tool seamlessly connect to all your data sources, including databases (SQL, NoSQL), cloud storage (AWS, Azure, Google Cloud), SaaS platforms (Salesforce, Workday), and file systems? Consider both structured and unstructured data compatibility.
2. Scalability
Can the tool handle your current data volume and anticipated growth comfortably? Ensure the tool can scale reliably without performance hiccups if your data landscape constantly expands.
3. Sensitivity Levels
Does the tool allow for granular classification and tagging of data based on sensitivity? You should be able to categorize data with varying risk levels for appropriate security and compliance measures.
4. Automation
How much of the discovery process can be automated? To streamline your workflows, look for tools that offer customizable scheduling, pattern recognition, and auto-tagging features.
5. Reporting and Visualization
Can the tool generate clear, insightful reports for audits, analytics, and executive summaries? Does it have visualization features to turn data patterns into easy-to-understand graphs and charts?
6. Integration Capabilities
Look for seamless integration with data catalogs, security tools, and business intelligence platforms. Consider specialized solutions like SaaS security posture management platforms (SSPM) for comprehensive cloud security assessment.
7. Cost-effectiveness
Evaluate the total cost of ownership, including licensing, support, deployment, and training. Balance your budget with the long-term value and ROI the tool provides.

Implementing Data Discovery: A Strategic Approach
Kicking off data discovery involves strategically mapping out where and how to look for hidden data. You want to ensure your efforts align with your organization’s priorities and security needs.
Connecting to Data Sources
First, get your data discovery tool to connect where your data lives. Data could reside within databases, be stored in cloud solutions, or be distributed among various SaaS platforms. Selecting a tool with extensive compatibility and integration capabilities will facilitate a thorough and frictionless discovery process.
Defining What to Discover
Understand that not all data holds the same value or risk, so focus on the sensitive bits: customer information, data regulators monitor, and anything directly impacting your business goals. This step is about filtering the noise to spotlight the data that's either a potential risk or a potential win.
Configuration
Decide on the frequency and depth of your scans. Deep scans are more time-consuming but essential for sensitive or critical data areas. A lighter scan might be adequate for general oversight. Determine whether to rely more on scheduled scans, which run automatically at set intervals, or on-demand scans, which you can launch manually in response to specific concerns or events.
Data Discovery in Action: A Compliance Use Case
Consider an analyst preparing for an upcoming audit focusing on personally identifiable information (PII). Aware of the impracticality of manual searches across extensive data repositories, they turn to their data discovery tool for assistance. Here's how the process might unfold:
Data Discovery is the Foundation for Data Governance and Analytics
A well-executed data discovery and governance strategy maximizes the value of your organization's data assets. It’s more than just finding and organizing your data---it’s also about integrating that discovered data into your systems for deep analysis and smart, strategic use.
Data Governance Integration
Feeding discovered data into data catalogs is critical in creating solid data governance. This process organizes raw data into a detailed, easily navigable inventory, essential for crafting clear data access policies and ensuring compliance.
Enhancing Reporting and Analytics
Structured data revealed through the discovery process forms the bedrock for improved reporting and analytics. By integrating this data into business intelligence (BI) dashboards, your organization gains granular insights into operational metrics and customer behavior.
Data Discovery for a Comprehensive Security Strategy
Pinpointing sensitive and high-risk data is the beginning of a truly effective security strategy. Implement continuous data monitoring alongside user training to receive real-time alerts on anomalies, suspicious activity, or unauthorized third-party access attempts.
Data Discovery Best Practices for DevSecOps
Adopting solid data discovery practices boosts your security and improves team collaboration. Here are some practical strategies:
User Training and Enablement
Ensure everyone who needs to use the tools knows how to use them effectively. Training should cover basic tool operations, advanced features, best practices for data analysis and threat detection, and the importance of integrating with security orchestration platforms.
The Evolving Data Landscape
Your data is constantly changing and growing in size and complexity. Regularly update your data discovery configurations and goals to maintain relevance and effectiveness against new data patterns and emerging threats.
Data Discovery is Your DevSecOps Advantage
In the fast-moving DevSecOps world, the cost of reactivity can be devastating. Data discovery provides the proactive advantage you need. It reduces code vulnerabilities, ensures compliance, and speeds up your response to incidents.
As you consider data discovery tools, prioritize those that align with your unique requirements. Whether your focus is on comprehensive scanning capabilities, integration ease, or specific compliance needs, the right tool does more than just the job---it sets you up for solid data governance and strengthens your security.
