What is Shadow IT Activity?

Shadow IT activity refers to the use of unauthorized hardware, software, or cloud services by employees without the knowledge or approval of the IT department. While often driven by a desire to boost productivity or find quick solutions, these shadow IT tools can expose your organization to significant risks, including data breaches, non-compliance with regulations, and potential cyberattacks. So, how can you tell if shadow IT is present in your company? Start by conducting regular audits of network traffic, monitoring cloud usage, and using specialized tools to detect unapproved applications. Identifying shadow IT is crucial, as even seemingly harmless tools can create vulnerabilities that compromise your entire security posture. To protect your organization, it’s essential to understand the scope of shadow IT activity, assess its risks, and implement strategies to regain control and visibility over your digital environment.

What is Shadow IT Activity?

Shadow IT activity involves the use of technology tools—such as software, applications, cloud services, or hardware—by employees without the approval or knowledge of the IT department. These shadow IT tools can range from personal file-sharing apps and messaging platforms to entire software-as-a-service (SaaS) solutions adopted by teams to meet specific needs. While these tools are often introduced with good intentions—such as improving collaboration or streamlining workflows—they bypass established security controls and policies, leading to serious risks for the organization.

Effective shadow IT management starts with understanding that shadow IT activity is almost inevitable, where employees seek quick solutions to their challenges. The problem arises when these unapproved tools create security vulnerabilities. For example, using unsanctioned cloud storage can lead to sensitive data being stored outside the organization’s control, increasing the risk of data breaches (in fact, up to 60% of data breaches are linked to shadow IT practices.) or non-compliance with regulations like GDPR or HIPAA.

To combat shadow IT activity, IT leaders need a proactive approach that includes monitoring network traffic, conducting regular audits, and deploying tools to detect unauthorized applications. Encouraging open communication about technology needs and providing secure, approved alternatives can also help reduce reliance on shadow IT. Ultimately, managing shadow IT effectively allows organizations to balance innovation and productivity with security and compliance, protecting both their data and their reputation in the process.

What Should You Do to Identify if Shadow IT is Present in Your Company?

To identify if shadow IT is present in your company, IT and security leaders need to take a proactive and multi-layered approach. Start by understanding that shadow IT can take many forms, from unauthorized cloud storage services to personal messaging apps used for work communication. These shadow IT examples can create significant security gaps that threaten your organization’s cybersecurity posture. Therefore, the first step is to establish visibility across the network. Deploy monitoring tools that can track network traffic and detect unusual patterns or access to unauthorized services. This includes tracking data flows to identify unknown applications that employees may be using without approval.

Next, conduct regular audits of software and devices used within your organization. Collaborate with department heads to get a sense of what tools are being adopted unofficially, and cross-check this against the list of approved applications. Utilize tools specifically designed for shadow IT in cybersecurity to detect and analyze all devices and software connected to your network, identifying any that fall outside of your approved list.

Additionally, implement user behavior analytics (UBA) to identify suspicious activities, such as large data transfers to unknown locations or repeated use of unauthorized applications. Engage employees by creating a culture that encourages transparency about technology needs. Provide training to raise awareness of shadow IT risks and encourage employees to report any unapproved tools they encounter.

By combining these methods, you can better identify shadow IT within your organization, minimize risks, and take steps to secure your digital environment effectively.

What Does Shadow IT Put Your Company at Risk For?

Shadow IT puts your company at risk for a wide range of security and compliance issues that can have severe consequences. The most immediate risk is the exposure to data breaches. When employees use unapproved tools or services, such as personal cloud storage or unauthorized messaging apps, these shadow IT tools often lack the security controls mandated by your organization. As a result, sensitive data can be stored in insecure locations, easily accessed by cybercriminals, or accidentally shared outside the company.

Additionally, shadow IT risks extend to regulatory compliance. Many industries are subject to strict data protection regulations, like GDPR, HIPAA, or CCPA. When employees use unauthorized applications to process or store customer data, it can lead to non-compliance, resulting in hefty fines, legal penalties, and damage to your organization’s reputation. Shadow IT also disrupts your company's cybersecurity posture by creating unknown attack surfaces that bypass your existing security measures, such as firewalls, intrusion detection systems, and endpoint protection.

Beyond cybersecurity, shadow IT can also lead to operational inefficiencies and increased costs. Unapproved tools may not integrate with existing systems, causing data silos, duplications, and conflicting workflows that hinder productivity. Moreover, organizations may face unexpected costs if unmonitored subscriptions or services accumulate over time.

To mitigate these risks, IT leaders must prioritize shadow IT management, ensuring visibility across the network, monitoring for unauthorized tools, and creating policies that balance security with the need for flexibility and innovation.
