Uncovering Shadow IT: The Hidden Risks in Your Network

Not all vulnerabilities in today’s networks start with malicious intent. Many employees are tech-savvy and, when systems aren’t working or feel slow, they often find their own solutions....because “there’s an app for that.” These workarounds truly can boost productivity, bridge functionality gaps, or streamline tasks.

However, these seemingly harmless tools can introduce serious security risks. This is Shadow IT, and it exists in every network. It can be as simple as checking personal email on a work computer or as complex as downloading open-source AI tools. Shadow IT is a persistent issue in modern workplaces—and it has even made headlines, such as the 2024 Disney/Slack incident.

What Is Shadow IT?

At its core, Shadow IT refers to the use of applications, devices, or services in the workplace that have not been approved or vetted by the IT department. This practice is more common than many realize: studies suggest that over 80% of employees use some form of unapproved technology, from personal phones and email accounts to third-party SaaS tools, to conduct business.

Why It Matters

Unapproved tools can create blind spots in your security posture. They may lack proper encryption, introduce vulnerabilities, or bypass compliance requirements. For network engineers and IT teams, identifying and mitigating these risks is critical.

How to Detect and Manage Shadow IT

Here are practical strategies to uncover and control Shadow IT:

• Network Traffic Analysis

  Use Robust monitoring systems for your network logs and traffic to identify unauthorized connections to cloud services or unusual data transfer volumes to unknown destinations.

• Cloud Access Security Brokers (CASBs)

  Use CASB solutions to gain visibility into cloud services employees are using, allowing IT to manage unsanctioned applications.

• Regular IT Audits

  Perform periodic assessments to scan for unauthorized devices and software that bypass standard IT processes.

• Continuous Asset Discovery

  Employ attack surface management tools to continuously discover all digital assets—both sanctioned and unsanctioned—for a complete view of your technology landscape.

• Endpoint Monitoring

  Use endpoint monitoring tools to detect unapproved apps and services running on employee devices, whether on or off the network.

  
  

Communication Is Key

Technology alone won’t solve Shadow IT. Open communication with employees is essential. Educate teams about the risks of unauthorized software and encourage transparency. Understanding user needs helps IT departments update policies that balance security with productivity.

Final Thoughts

Shadow IT isn’t going away—it’s a reality of modern work. By combining proactive monitoring, robust tools, and a culture of collaboration, organizations can reduce risk while empowering employees to work efficiently.
