Shadow IT refers to any hardware, software, or cloud service used by employees without the knowledge or approval of the IT department.
It often starts innocently—someone downloads a productivity app, connects to a third-party file-sharing service, or installs a browser extension to make work easier. But what feels like a shortcut can quickly turn into a serious security gap.
You can’t protect what you don’t know exists. And that’s what makes Shadow IT so dangerous.
When tools are used outside of IT’s radar, they don’t go through normal security checks—like patching, access control, or encryption.
Shadow IT can result in non-compliance with regulations like GDPR, HIPAA, or ISO 27001 if sensitive data is processed or stored in unauthorized locations.
Employees may use weak passwords, leave systems unpatched, or expose internal data through misconfigured tools.
When employees use personal Dropbox accounts, messaging platforms, or AI tools, your data may end up in systems you don’t own—and can’t secure.
Unauthorized Cloud Storage: An employee saves internal project files to a personal Google Drive account, which is later compromised.
Messaging Apps: Teams use unapproved chat tools to discuss client issues, exposing sensitive data in unencrypted channels.
Third-Party AI Tools: Employees feed customer data into generative AI platforms that store or reuse the information.
Network Traffic Monitoring
Look for outbound traffic to unapproved domains or cloud services.
Endpoint Audits
Use endpoint detection tools to identify unsanctioned apps or browser extensions.
Cloud Access Security Brokers (CASBs)
CASBs can detect and control the use of cloud services across your environment.
Engage Employees
Run internal surveys to identify tools employees use—and why they feel the need to go outside of approved systems.
Maintain and share a vetted list of secure applications employees can use freely.
If employees turn to Shadow IT, it’s often because the approved tools are too limited or slow. Make sure your supported software is usable and efficient.
Define what’s allowed, what isn’t, and why. Educate your staff on the risks—not just the rules.
Use tools like:
Data Loss Prevention (DLP) to block risky file transfers
Browser security policies to restrict extension installations
Identity and Access Management (IAM) to control who can use what
Shadow IT is one of the most common and most overlooked cybersecurity risks in modern businesses—especially with hybrid work and bring-your-own-device cultures.
The solution isn’t just to lock everything down. It’s to create visibility, engage your workforce, and build secure options that enable people to work safely and efficiently.
