Discover data protection

Data discovery defined

Imagine being able to see trends, identify opportunities, and mitigate risks in real time. That's the potential of data discovery, and it's a game-changer for businesses seeking a competitive edge. Data discovery is the process of extracting meaningful insights and patterns from a vast ocean of data. It involves identifying hidden trends, anomalies, and relationships within your data that might not be immediately apparent. Think of it as the treasure hunt for valuable insights buried within your datasets. It's not about collecting more data; it's about making sense of the data you already have and transforming it into knowledge that can guide your business strategy.

 

Data discovery vs. traditional data analysis
 

Traditional data analysis involves predefined queries and structured data. Analysts know what they're looking for and use specific queries to extract the desired information. Data discovery, on the other hand, is a more exploratory process. Analysts don't always know what they're looking for initially. Instead, they use data discovery tools to sift through the data, uncovering insights along the way.

In a world where data is abundant but insights are precious, data discovery helps organizations uncover hidden gems of knowledge that can lead to:
 
  • Stronger data security.
  • Faster and more accurate decision making.
  • Cost savings.
  • Improved customer insights.

The benefits of data discovery

Data discovery is a powerful tool that can transform your business operations and decision-making processes—and propel your organization to success.

Informed decision making

Uncover patterns, trends, and outliers within your data so you can make choices based on data-driven evidence rather than intuition alone.

Enhanced efficiency

Streamline processes and operations by identifying bottlenecks, inefficiencies, and other areas that need improvement. For example, you can use data discovery to optimize supply chain logistics, reduce production waste, or streamline customer support workflows. These efficiency gains often translate into cost savings that can be reinvested into strategic initiatives.

Competitive advantage

Identify emerging market trends, understand customer behavior, and predict future demands.

Solid security

Identify and mitigate risks with data discovery tools that help you spot potential risks early on, whether they’re related to market volatility, cybersecurity threats, or regulatory compliance.

Innovation

Encourage a culture of experimentation and adaptability, and fuel innovation with insights that inspire new product ideas, service offerings, or business models.

How data discovery sheds light on unstructured data

Not all data neatly fits into structured databases or spreadsheets. Unstructured data is data that doesn't conform to a specific, predefined data model or schema. Unlike structured data, which resides neatly in rows and columns, unstructured data can include text documents, emails, social media posts, images, and videos.

Businesses generate vast amounts of unstructured data every day that could contain valuable information, such as customer sentiments, emerging trends, and market perceptions. Unfortunately, it can be a challenge to glean actionable insights from these huge datasets.

Finding the hidden value in unstructured data. Data discovery tools help organizations make use of their unstructured data. Through natural language processing, image and video analysis, and document parsing, these tools can extract actionable insights from previously unmined sources.

Then, by combining these unstructured data points with structured ones, discovery tools can provide a more holistic view of your business environment—and you can make decisions based on both numbers and contextual insights.

Imagine a retail business that receives a lot of customer reviews and comments on social media. These online interactions could contain valuable feedback about product quality, customer service, and emerging trends. Data discovery tools can analyze this unstructured data, extract sentiment patterns, and provide actionable insights for improving products and services.

The data discovery process

So how does data discovery actually do all of this? How does it help uncover actionable insights from both structured and unstructured datasets? It’s a six-step process:
 
  • Step 1. Define your objectives.
    Before embarking on any data discovery journey, it's crucial to define your objectives. What questions do you want to answer? What insights are you seeking? Having clear objectives will guide your data exploration and analysis.
  • Step 2. Combine your data sources.
    Data discovery begins with data collection. Identify and gather relevant datasets—both structured and unstructured, as well as external data from third-party sources.
  • Step 3. Clean and prepare your data.
    Clean, transform, and prepare your data for analysis. This step involves handling missing values, dealing with outliers, and normalizing data. Data preprocessing ensures that your data is ready for more in-depth analysis.
  • Step 4. Visualize the data.
    Simplify complex data by creating visual representations that are easier to understand and that facilitate comparison of multiple data points. Data visualization can help show trends, outliers, and areas of interest—and communicate said findings more effectively.
  • Step 5. Analyze.
    Formulate hypotheses and conduct statistical or analytical tests to explore relationships and patterns within your data. Data discovery tools can assist in this phase by uncovering hidden correlations or trends.
    Interpret the results of your analysis in the context of your objectives. What do the findings mean for your business? Can you use these insights to optimize processes, launch new products, or adjust marketing strategies?
  • Step 6. Repeat the process.
    Data discovery isn’t a one-time event—it’s an iterative process. As your business evolves and new data becomes available, revisit your objectives and continue exploring. The data discovery journey never truly ends.

    Data discovery is more than just a series of steps; it's a mindset that values curiosity, exploration, and a commitment to continuous improvement. Embrace the spirit of discovery, and you'll find that your data becomes a strategic asset.

Why is data governance important for data discovery?

Data governance is the framework of policies, processes, and practices that ensure high data quality, uniform data management, and information security within an organization. It's the structure that governs how data is collected, stored, and used—and who has access to what information.

Governance is the unsung hero behind successful data discovery. It improves the accuracy of an organization’s data so that discovery efforts have quality information to explore. This helps streamline the discovery process and instills trust in the insights derived from it. It also helps ensure that any data discovery adheres to regulatory requirements and that data isn’t being improperly used.

Using data discovery as a data security tool

Data is a valuable asset, but it's also a potential liability. Businesses today are entrusted with vast amounts of it, including customer information, financial records, and proprietary intellectual property—all of which are potential targets for cybercriminals.

With an increasing amount of data breaches and cyber threats, securing sensitive information is paramount. Breaches can have devastating consequences such as financial losses, damaged reputations, and legal repercussions.

Data discovery tools, though traditionally associated with uncovering insights, can also serve as formidable allies in the battle against breaches. Through sensitive data discovery, organizations can more proactively protect their data estate by pinpointing vulnerable data and security gaps. These tools help to:

  • Identify vulnerabilities.
    As they scan and analyze data repositories, discovery tools can also identify potential security vulnerabilities by shining a light on exposed or improperly stored data.
  • Monitor in real time.
    Many data discovery solutions offer real-time monitoring capabilities. They can detect unusual data access patterns or unauthorized attempts to access sensitive information and trigger alerts for immediate response.
  • Classify data.
    Effective data security begins with understanding what data you possess and its sensitivity level. Data discovery tools can classify data based on predefined criteria, ensuring that sensitive information is adequately protected.
  • Assist with compliance.
    For businesses subject to data privacy regulations such as the European Union’s General Data Protection Regulation, data discovery tools can aid in compliance by identifying areas where protection measures fall short.
  • Detect insider threats.
    Breaches aren’t always the result of external threats. Data discovery tools can help detect unsafe or suspicious activities by employees, contractors, or other insiders.

A holistic approach to data security
Data security and data discovery are interconnected. After all, cybersecurity isn't just about building stronger walls—it's about gaining visibility into your digital ecosystem. Once you understand where the vulnerabilities lie, you can proactively protect your assets.
