In the digital age, data is essential for any organization. However, not all data is managed effectively. A hidden risk that often goes unnoticed is shadow data. This unmanaged and unmonitored data can create significant vulnerabilities for businesses. Let’s explore what shadow data is, why it’s dangerous, and how organizations can address it effectively.
What Is Shadow Data?
Shadow data refers to any organizational data that exists outside of your company’s approved IT systems or governance framework. This could include files stored on personal devices, data shared through unauthorized cloud services, or forgotten backups left in unmonitored environments. Essentially, it’s the data that slips through the cracks of your formal IT policies.
Shadow data often arises from well-meaning actions, such as:
A developer copying sensitive production data into a testing environment and forgetting to delete it.
Employees sharing files using unsanctioned collaboration tools for convenience.
Legacy systems or old backups containing sensitive information that no one remembers.
While these actions may seem harmless, they create a growing pool of unmanaged data that is invisible to IT teams—and that’s where the danger lies.
Why Is Shadow Data Dangerous?
Shadow data poses several risks that can have serious consequences for your organization:
1. Security Vulnerabilities
Since hidden data isn’t monitored or secured like official data, it becomes an easy target for cybercriminals, potentially leading to breaches of sensitive information.
2. Compliance Risks
Many industries are governed by strict regulations regarding data privacy and security. Shadow data often exists outside these controls, putting your organization at risk of non-compliance and resulting in fines and reputational damage.
3. Operational Inefficiencies
Unmanaged data can lead to inaccurate reporting and decision-making because it creates blind spots in your organization’s overall data landscape.
4. Extended Breach Impact
Breaches involving shadow data are harder to detect and contain because IT teams often don’t know this data exists, prolonging response times and increasing costs.
How Can You Shine a Light on Shadow Data?
Preventing shadow data from being forgotten requires a proactive approach:
Establish Clear Data Governance Policies
Define where and how employees should store and manage organizational data, ensuring these policies are communicated clearly.Educate Employees
Train staff on the risks of using unauthorized tools or storing sensitive information outside approved systems.Provide Approved Tools
Offer secure alternatives for file sharing and collaboration so employees don’t feel the need to use unsanctioned platforms.Conduct Regular Audits
Periodically review your organization’s systems to identify unmanaged or unapproved data sources.
Best Practices for Managing Shadow Data
Hidden data probably already exists in your organization, here are some ways to manage it effectively:
1. Discover and Classify Data
Use smart automated tools to scan your environment for unmanaged datasets and classify them based on sensitivity.
2. Assess Risks
Evaluate the potential impact of each piece of shadow data if exposed or breached, focusing on securing high-risk datasets first.
3. Secure or Eliminate
Bring important shadow data under formal management by migrating it into secure systems with proper access controls or securely deleting unnecessary files.
4. Implement Continuous Monitoring
Adopt tools that provide ongoing visibility into your organization’s entire data ecosystem—including potential hidden sources.
Why Should Organizations Care About Shadow Data?
Organizations should care about hidden or forgotten data because ignoring it can lead to costly consequences:
Data Breaches: Unsecured shadow data increases vulnerability to attacks.
Regulatory Fines: Non-compliance with laws due to unmanaged shadow data can result in significant penalties.
Reputational Damage: A breach involving sensitive customer information can erode trust with clients and partners.
Wasted Resources: Storing unnecessary shadow data increases cloud costs and complicates IT management efforts.
By addressing shadow data proactively, organizations can improve their security posture, reduce costs, and maintain compliance with industry standards.
