and shadow data
Address shadow data to shrink the attack surface and reduce data storage costs.
What is Shadow Data?
Shadow Data is the data generated by Shadow IT that is unmanaged and ungoverned by the security team.
Shadow IT is the use of technology and cloud services without explicit approval or oversight from the IT and security departments, sometimes through cloud-based services provisioned by a line of business.
Shadow IT is the use of technology and cloud services without explicit approval or oversight from the IT and security departments, sometimes through cloud-based services provisioned by a line of business.
So what’s the big deal?
- With no involvement, the security team can’t fulfill its role of ensuring that all data in the organization, including Shadow Data, is secure.
- Shadow Data can cause a significant financial cost to the organization if breached, and therefore needs to be properly secured.
- Since it is untracked or unmanaged by IT and security teams, Shadow Data can accumulate unnoticed, leading to increased monthly storage costs.
Recognizing this risk is the first step toward implementing

What are the Security Risks of Shadow Data?
When employees adopt services and applications not sanctioned by the security team, they are not always aware of the security implications to the company.
Data sprawl compounds the issue. Data from processes like CI/CD, data analytics, ML & AI, and abandoned backups add to the volume and complexity of Shadow Data that needs to be secured.
A data analytics team might pull data from various internal and external sources into a data platform like Snowflake or Amazon Redshift and manipulate it for broadened insights and better-informed decision-making. However, the data may contain sensitive customer records or be subject to compliance regulations that the analytics team isn’t focused on, and it may be retained after it is no longer needed.
Addressing Shadow Data Risk with Normalyze
Lack of visibility
Risk
- The security team doesn’t know about Shadow Data or its sensitivity.
- IT teams can’t manage the lifecycle of data and removal of sensitive data when it is no longer needed.
- Response times to potential threats can be slower as a result of limited visibility and can lead to more reactive security vs. proactive.
Solution
- Discover and classify data across your entire hybrid infrastructure, including Shadow Data. Identify all locations where your data resides, even when others in the business might have forgotten about these stores/applications.
Misconfiguration of data stores
Risk
- Not all configurations may meet company standards.
- Temporary, test, or ‘sandbox’ data stores may contain sensitive data with exposure risk.
Solution
- Identify and prioritize data that is not properly secured.
Weak access governance controls
Risk
-
Shadow IT may have over-provisioned users and roles that are susceptible to phishing and insider threats.
Solution
- Identify over-provisioned users and roles and enforce the principle of least privilege.
Increased exposure to external threats
Risk
-
Vulnerable resources may have access to sensitive data, even if the data itself is properly secured.
-
Security teams are also unable to protect data they don’t know exists, yet the business might still be liable for misuse.
Solution
- Context-based risk assessment identifies all potential attack paths to your data for quick resolution of direct and indirect threats. Continuous monitoring ensures you are aware of any changes leading to increased exposure.
Risk
-
Requirements are complex and vary by region and industry, and violations can lead to significant fines.
-
Security teams can’t ensure that unauthorized applications remain compliant.
Solution
- Continuously monitor regulatory compliance across multiple regulations and quickly identify which controls are being missed.
Ransomware attacks
Risk
-
Attackers can threaten reputational damage or sensitive data exposure.
Solution
- Get cyber recovery and ransomware protection capabilities with the Normalyze-Cohesity integration.
Increased data storage costs
Risk
-
Shadow data may contain redundant or outdated information that wastes storage resources.
-
Unused data increases monthly storage expenses, adding to overall IT costs.
Solution
- Use Normalyze’s advanced tools to identify and manage shadow data stores. Move older, infrequently accessed data to slower, lower-cost storage and delete unneeded data to reduce expenses.
Shadow IT: Mitigating Security Risks
To mitigate the security risks of Shadow Data, organizations must adopt proactive measures. Here are some practical steps to protect your sensitive Shadow Data:
Establish a Shadow IT Security Policy
- Develop a comprehensive policy that addresses the acceptable use of cloud services, clarifies the security team’s role in approving and managing technology, and promotes employee awareness about potential risks.
Enhance Data Visibility
- Get comprehensive visibility into all the data, including Shadow Data generated by services being used within your organization, and classify its sensitivity.
Strengthen Access Controls
- Perform data access governance and implement robust identity and access management (IAM) practices to ensure that only authorized personnel can access sensitive data and cloud resources.
- Enforce multi-factor authentication, role-based access controls, and regular access reviews, as well as the principle of least privilege.
Manage Risk
- Identify misconfigurations and attack paths to data from resources that can access it.
- Proactively monitor for compliance with regulatory requirements.
Address Issues
- Mitigate identified risks for all your data, including Shadow Data, and automate where possible.
- Delete unneeded data and move infrequently used data to appropriate storage tiers.
Educate Employees
- Conduct regular training sessions to educate employees about the risks associated with Shadow Data and the importance of adhering to approved technology guidelines.
- Encourage employees to report any unauthorized cloud services or security concerns promptly.
