Shadow IT Tools

Learn what Shadow IT is, why employees use it, and how to detect and manage it effectively. Explore the risks of Shadow IT and best practices for maintaining security and productivity in your organization.

Shadow IT. It sounds mysterious, like something out of a spy thriller, but for IT and security leaders, it’s less about secret agents and more about unsanctioned devices and software creeping into your network. These are the rogue apps and gadgets employees use without official approval—sometimes out of convenience, sometimes ignorance, and sometimes sheer frustration with the "official" tools. This might mean everything from unauthorized cloud services to personal devices connecting to corporate resources. Think of that one time a team member used a random file-sharing app because the company’s solution felt like navigating a labyrinth. Shadow IT isn’t just a security risk; it’s a stealthy, often invisible challenge.

What Are Shadow IT Devices?

If you’re managing an IT or security team, you’ve probably heard the term “Shadow IT” more than you’d like to admit. It's not some clandestine operation run by your most rebellious employees—though it can feel that way. Shadow IT devices are any hardware or software tools used by employees without the knowledge, approval, or oversight of the organization’s IT department. Think laptops, smartphones, or even USB drives brought from home, as well as applications downloaded on a whim, like that nifty new project management app nobody in IT has heard of.

Understanding Shadow IT Devices: A Double-Edged Sword

Shadow IT is all about one thing: convenience. Employees turn to unapproved devices and apps when they feel the tools provided by the organization are too slow, outdated, or cumbersome. So, they use their own phones, tablets, or other gadgets to get things done faster. It sounds harmless enough—until you consider the security implications. Every Shadow IT device introduces potential vulnerabilities. Imagine someone using a personal laptop to access sensitive company data without the necessary encryption or security protocols. Or an unvetted cloud storage service where your company’s confidential information is unknowingly being stored. It's like leaving your front door wide open and hoping no one notices.

Common Shadow IT Devices and Their Risks

A list of common shadow IT devices and their risks
Common shadow IT devices and their risks.

Shadow IT examples can range from seemingly harmless to potentially catastrophic. Here are some common culprits:

1. Personal Laptops and Desktops: Employees may prefer their own computers because they’re faster, have better software, or just feel more comfortable. But without IT management oversight, these devices might lack essential security patches or antivirus software, creating a vulnerability in your network.

2. Mobile Devices: Smartphones and tablets are classic Shadow IT devices. Employees might use them to check work emails, download documents, or even run company apps. Without proper management, these devices can become entry points for malware or phishing attacks.

3. USB Drives and External Storage: These little gadgets are often overlooked, but they can carry significant risks. An employee may use an unauthorized USB drive to transfer data quickly—only to accidentally introduce malware into the corporate network.

4. Cloud Services and Apps: This is a big one. Employees might turn to unapproved cloud storage or collaboration tools because they’re faster, more user-friendly, or offer more features than the company-approved options. While this boosts productivity, it also opens a Pandora’s box of security issues, from data breaches to compliance violations.

Why Shadow IT Is a Growing Concern  

So, why are these Shadow IT devices proliferating in the workplace? Part of the reason is the rapid pace of technological innovation. New tools and apps are constantly emerging, promising to make work easier, faster, and more efficient. Employees are eager to leverage these technologies, often without waiting for IT approval. But there’s another factor at play: frustration with existing systems. When corporate IT tools are outdated, slow, or don’t meet employees’ needs, they’ll naturally look elsewhere for solutions that do.

Shadow IT Management: The Balance Between Security and Productivity  

Here’s the real challenge: balancing the need for security with the drive for productivity. Shadow IT management isn’t about stifling innovation or punishing employees for taking initiative. Instead, it’s about understanding why they feel the need to turn to unapproved devices or apps in the first place. Are the current tools inadequate? Is there a lack of training or awareness around the approved solutions?

To manage Shadow IT effectively, organizations need a multi-pronged approach. First, foster open communication between employees and the IT department. Make it easy for employees to request new tools or devices and provide clear guidelines on what is allowed and why. Second, implement monitoring solutions to detect unauthorized devices and applications. Third, educate employees about the risks associated with Shadow IT and the importance of adhering to company policies.

Detecting and Mitigating Shadow IT  

Detecting Shadow IT devices can be like playing a never-ending game of whack-a-mole. You close one loophole, and another opens up. But with the right tools and strategies, it’s possible to get a handle on it. Start with network monitoring tools that can detect unknown devices or applications attempting to access your network. Regular audits and vulnerability assessments can also help identify potential Shadow IT risks.

Once you know what you're dealing with, it's all about mitigation. This could involve restricting access to certain types of data or applications, deploying endpoint management solutions, and enforcing strong security policies. It’s not about playing the role of the IT police—it’s about safeguarding the organization while still enabling employees to be effective and innovative.

Why Do Employees Use Shadow IT?

Let’s face it—every IT leader’s worst nightmare is hearing the words “I just found this great app” from a well-meaning employee. Why do they choose to sidestep the approved systems and go rogue with their own Shadow IT tools? The answer lies at the intersection of convenience, frustration, and the pace of modern work.

  • The Productivity Push: Faster, Easier, Better

At the heart of the Shadow IT problem is the quest for productivity. Employees are often expected to do more with less and in less time. If the approved tools provided by the organization are slow, complex, or don’t quite meet their needs, employees are likely to find their own solutions. Why struggle with a clunky, outdated project management software when a sleek, user-friendly app is just a download away? These Shadow IT tools promise to simplify workflows, automate tedious tasks, and offer features that the official software may lack—all of which makes them incredibly appealing to time-strapped employees.

  • The Desire for Flexibility and Personalization  

Today’s workforce is accustomed to a level of customization in their digital lives that many corporate tools just don’t offer. Employees want to use tools they’re familiar with and that fit their personal work style. This desire for flexibility and personalization is a big reason why employees turn to Shadow IT. Maybe they prefer a particular cloud storage service because it integrates better with their personal devices, or they favor a different video conferencing app because it has features that their team needs but the company-approved tool doesn’t support. Whatever the reason, employees often feel that these unofficial tools give them the flexibility they need to work the way they want to work.

  • Work-from-Home and BYOD Culture  

The rise of remote work and Bring Your Own Device (BYOD) culture has blurred the lines between personal and professional technology use. Employees who are working from home or on the go might find it more convenient to use their own devices and software rather than the corporate-provided options. After all, when you’re juggling multiple devices and trying to maintain a work-life balance, it’s easier to use a single tool that serves both purposes. This creates fertile ground for Shadow IT in cybersecurity, as employees mix personal and work data on unapproved devices, creating potential vulnerabilities that are harder for IT teams to manage.

  • The Frustration Factor: IT Bureaucracy and Slow Approvals  

Nobody likes jumping through hoops, especially when there’s a deadline looming. In many organizations, getting a new tool approved by IT can feel like pulling teeth—painful, slow, and often without a guarantee of success. Employees may feel that the process is too cumbersome or that IT is out of touch with the realities of their day-to-day work. As a result, they bypass the red tape and adopt Shadow IT tools to get the job done now, rather than waiting weeks or even months for the official green light.

  • Lack of Awareness About Cybersecurity Risks  

Here’s a dirty little secret: not everyone knows—or cares—about cybersecurity the way they should. Employees often don’t understand the full extent of the risks involved with Shadow IT. They might not realize that using an unapproved file-sharing app could expose sensitive data or that connecting their personal devices to the corporate network could create vulnerabilities. In many cases, it’s not malicious intent that drives Shadow IT adoption, but simply a lack of awareness about the potential cybersecurity threats. They see Shadow IT tools as harmless shortcuts rather than potential gateways for hackers.

  • Peer Influence and the Bandwagon Effect  

People like to follow the crowd. If one team member starts using a new, unofficial tool that makes their life easier, others are likely to follow suit. This is particularly true in large organizations where trends can spread quickly. Employees see their peers using Shadow IT tools and think, “If it works for them, why not for me?” This bandwagon effect can lead to widespread adoption of unauthorized tools before IT even knows what’s happening.

How Can Organizations Combat Shadow IT?  

Understanding why employees use Shadow IT is the first step in addressing the issue. Organizations can’t just throw up firewalls and hope for the best. Instead, they need to strike a balance between security and usability. Make it easier for employees to request new tools or provide feedback on existing ones. Improve communication between IT and other departments, so employees feel their needs are understood and addressed. Invest in training programs that help employees understand the risks associated with Shadow IT in cybersecurity, and encourage them to think twice before downloading that new app or connecting an unapproved device.

What is Shadow IT in Microsoft?

In a Microsoft environment, where tools like Microsoft 365, Azure, and Teams are the backbone of corporate infrastructure, Shadow IT can pose some unique risks. But what does Shadow IT look like in the context of Microsoft, and how does the company help organizations manage these risks?

Understanding Shadow IT in the Microsoft Ecosystem  

In Microsoft environments, Shadow IT can manifest in various ways. Employees might use unapproved cloud services for file sharing, messaging apps for team communication, or personal devices to access corporate data. While these might seem like small infractions, they can create significant security and compliance challenges, especially in organizations heavily invested in Microsoft’s tools and services.

Consider the scenario where an employee uses an unauthorized cloud storage service to share files because it offers more features than OneDrive or SharePoint. Or imagine another situation where a team uses a non-Microsoft project management app that isn’t integrated into the company’s Microsoft 365 suite. These might seem like minor workarounds, but each introduces potential Shadow IT risks—from data breaches and loss of sensitive information to compliance violations and exposure to malware.

Shadow IT Cloud Discovery in Microsoft  

So, how can organizations detect and manage Shadow IT within a Microsoft environment? Enter Shadow IT Cloud Discovery in Microsoft Defender for cloud apps. Cloud Discovery is a feature of Microsoft Defender for Cloud Apps (formerly Microsoft Cloud App Security) that helps organizations identify and manage unsanctioned cloud services and applications being used by employees. It provides visibility into cloud usage, helps assess potential risks, and enables IT teams to enforce policies around cloud service usage.

What is an Example of Shadow IT?

Imagine this: Your marketing team is gearing up for a big campaign. They’re under tight deadlines and need to collaborate quickly. But the company’s approved file-sharing tool feels slow, clunky, and not particularly user-friendly. So, one team member decides to use a personal Google Drive account to share files with external partners because it’s fast, familiar, and gets the job done without the hassle. That’s a classic example of Shadow IT.

Breaking Down This Example of Shadow IT

Here, Google Drive is the Shadow IT tool—an application or service that’s being used without the knowledge or approval of the IT department. From the employee’s perspective, it’s a convenient solution to a frustrating problem. However, from a security standpoint, this action creates a potential nightmare. When files containing sensitive customer information or confidential data are uploaded to an unauthorized cloud service, the organization loses control over where that data is stored, who can access it, and how it’s protected.

Why This is a Problem  

The risk isn’t just theoretical. By using an unapproved tool like a personal Google Drive, employees might inadvertently expose data to unauthorized access or compromise compliance with regulations like GDPR, HIPAA, or CCPA. There’s also the risk of data leakage if the employee’s Google account is hacked or if the data is shared accidentally with the wrong people. In some cases, even if data isn’t exposed, the organization may still face fines or penalties for non-compliance with industry-specific regulations.

Another Real-World Example: The Messaging App Dilemma  

Let’s consider another scenario. Your sales team, always on the move, finds the company’s official communication tool a bit slow and clunky on mobile devices. So, they opt to use a popular messaging app like WhatsApp to share quick updates, client information, or even sensitive documents. On the surface, it seems harmless—after all, everyone uses WhatsApp. But by communicating outside of approved channels, the organization loses control over how sensitive data is handled. The data now resides on employees’ personal devices, outside the organization’s security perimeter, making it much harder to track or protect.

How to Detect Shadow IT?

Detecting Shadow IT can feel like searching for a needle in a haystack. But with the right shadow IT policy approach and tools, you can shine a light on these hidden activities and reduce their associated risks. Here’s how to get started.

1. Use Network Monitoring Tools

The first line of defense in detecting Shadow IT is to monitor network traffic. Tools like firewalls, Secure Web Gateways (SWGs), or Intrusion Detection Systems (IDS) can analyze data traffic patterns and detect unknown or unauthorized applications communicating over the network. By examining this traffic, IT teams can identify applications that aren’t on the company’s approved list and then take steps to investigate their usage. The trick is to configure these tools to alert you whenever an unknown app appears, so you’re not manually combing through endless logs.

2. Implement Cloud Access Security Brokers (CASBs)  

A Cloud Access Security Broker (CASB) is a critical tool for identifying Shadow IT, especially in organizations heavily reliant on cloud services. CASBs provide visibility into cloud usage by monitoring traffic between employees and cloud service providers. They can detect which cloud apps are being accessed, who is using them, and what data is being shared.

3. Conduct Regular Audits and Assessments  

Regular audits are essential to uncover Shadow IT. Start with a thorough inventory of all approved applications and devices. Then, use data from network monitoring tools, CASBs, and endpoint management systems to compare this against actual usage. Pay special attention to third-party apps that may be connecting to your network or accessing company data. Engage in frequent discussions with department heads and employees to understand what tools they are using, and why, which can help you spot trends in Shadow IT adoption early.

4. Use Endpoint Detection and Response (EDR) Tools

Endpoint Detection and Response (EDR) tools can help you detect Shadow IT by monitoring and analyzing endpoint activity. These tools provide visibility into applications installed on employee devices and alert IT teams to any unauthorized software. EDR solutions can detect suspicious behaviors or unknown apps running on devices, helping you identify Shadow IT risks before they become full-blown security issues.
