How Shadow IT Turns Employees Into Unintentional Insider Threats
Employees are seeking quick and convenient tools to get the job done, whether IT approves them or not. This widespread use of "Shadow IT" is exposing companies to security breaches, data loss, and compliance failures.

Shadow IT refers to the unauthorized adoption of software, hardware, or other technological solutions by individuals or groups within a company. The adoption occurs without the awareness or approval of the organization’s central IT department. In contrast to formal IT systems, shadow IT operates outside official management and oversight.
A recent survey revealed that 59 % of U.S. employees admit to using unapproved AI tools for work, often without their employer’s knowledge. A Microsoft report found that 71 % of employees in the UK have used unapproved consumer AI tools at work, with more than half continuing to use them weekly.
What Shadow IT Usage Looks Like
The scope of Shadow IT extends far beyond an employee installing unapproved software on a work laptop. It may include employees storing sensitive work files in personal cloud drives, such as Dropbox or Google Drive, for easier access. Employees may also sign up for SaaS (Software-as-a-Service) applications, such as project management or communication tools, without going through the official procurement channels.
Browser extensions that manage passwords or read email content can also pose major risks as they often have extensive permissions to access and transmit corporate data. More recently, the rapid adoption of generative AI tools by employees to summarize reports, draft communications, or even analyze proprietary source code has become a major new frontier for Shadow IT, introducing complex data privacy and intellectual property concerns.
Why Employees Turn to Shadow IT
Shadow IT does not appear randomly. It develops from a mix of organizational processes, employee expectations, and modern technology trends. When these factors collide, employees often create their own solutions outside official IT oversight.
1. Lack of clear visibility and structure around IT procurement.
When teams need new tools but don’t understand how to request them or expect the process to be slow and unclear, they may bypass IT entirely. This can involve signing up for free trials, purchasing software, or using personal accounts.
2. Pressure to find faster solutions.
Lengthy approval cycles can clash with tight deadlines and performance expectations. When work needs to move quickly, employees may choose speed over policy, adopting tools that help them deliver results immediately. While this approach feels practical in the moment, it often leads to the quiet spread of unapproved systems across the organization.
3. Officially provided tools fail to meet real-world needs.
If IT-approved software is difficult to use, lacks essential features, or does not align with how certain teams work, employees will look for alternatives. These workarounds may improve productivity in the short term, but they often create security blind spots and compliance challenges that go unnoticed until a problem occurs.
4. The widespread availability of cloud-based services.
Nowadays, software-as-a-Service platforms make it easy for anyone with an email address and a credit card to deploy powerful tools in minutes.
The Risks of Shadow IT
1. Employees Bypass Security Controls Without Knowing It
Approved IT systems are continuously monitored, regularly patched, and protected through established security controls and logging mechanisms. These safeguards allow IT teams to detect suspicious activity, apply updates, and respond quickly when issues arise. Shadow IT tools, by contrast, exist outside this managed environment and do not benefit from the same level of oversight or protection.
When employees rely on unapproved applications, sensitive data may be stored without proper encryption, making it easier to access or steal. Access controls in these tools are often weak, poorly configured, or entirely absent, allowing data to be shared far more broadly than intended. In addition, security updates and patches may be delayed or never applied, leaving known vulnerabilities exposed for long periods of time.
From a security standpoint, this effectively places critical business information beyond the organization’s defensive perimeter. Data handled through shadow IT operates in blind spots where monitoring is limited or nonexistent, increasing the likelihood that breaches will go undetected until real damage has already occurred.
2. Employees Accidentally Enable External Attacks
Shadow IT expands an organization’s attack surface by introducing systems and access points that fall outside formal security controls. Each unapproved tool or device creates a new entry path that attackers can exploit, often with far less resistance than properly secured corporate systems.
For example, employees may use SaaS tools protected by weak or reused passwords, making them easy targets for credential stuffing or account takeover attacks. Other applications may lack multi-factor authentication altogether, allowing attackers to gain access with nothing more than stolen login details. Browser extensions, often installed for convenience, can also be compromised through malicious updates, silently gaining access to emails, files, or internal systems.
Personal devices used for work further increase risk, especially when they are infected with malware or lack up-to-date security protections. In these scenarios, attackers don’t need to penetrate well-defended corporate infrastructure. Instead, employees unintentionally provide a backdoor, granting access through tools and devices that were never meant to be part of the organization’s security perimeter.
3. Compliance Violations Become Inevitable
Regulatory frameworks such as GDPR require organizations to maintain strict control over how data is collected, stored, accessed, and deleted. Shadow IT undermines these requirements by operating outside approved systems and processes, making compliance difficult by default rather than by exception.
When employees use unapproved tools, regulated data can end up stored in platforms that do not meet legal or security standards. These systems often lack clear data retention and deletion policies, making it impossible to ensure that personal or sensitive information is kept only as long as required. In addition, organizations may struggle to locate data or provide accurate records when responding to audits, investigations, or legal requests.
When compliance failures or data protection violations occur, regulators do not distinguish between approved systems and shadow IT. Responsibility rests entirely with the organization, regardless of how or why the data was mishandled.
How Organizations Can Reduce Shadow IT Risks
1. Make Approved Tools Easier Than Shadow IT
One effective approach is to make approved tools more appealing and easier to use than their unsanctioned alternatives. Employees are naturally drawn to solutions that save time and simplify work. If the official tools provided by IT are faster, more intuitive, and better integrated with existing workflows, employees are far less likely to turn to unapproved applications. This requires continuous investment in user-friendly platforms and responsive IT support that addresses real employee pain points.
2. Create Fast, Transparent Approval Paths
Long, bureaucratic IT procurement cycles often push teams toward shadow IT simply to meet deadlines. Fast approvals, combined with a transparent process, build trust between employees and IT, reducing the incentive to act outside official channels.
3. Educate Employees
Education is equally important. Employees need to understand why certain tools are risky, what the potential consequences are, and how their actions affect the organization. Training programs should focus on awareness and empowerment rather than fear or blame. When employees feel informed and trusted, they are more likely to collaborate with IT rather than hide their tool usage.
5. Treat Shadow IT as Feedback
Organizations should treat shadow IT as valuable feedback rather than purely a threat. The tools and solutions employees adopt outside of IT oversight often reveal unmet needs, inefficiencies, or gaps in official systems. Analyzing these patterns can help adapt IT to better meet real-world requirements, reducing frustration and preventing the proliferation of unapproved tools.
Final Thought
Shadow IT doesn’t turn employees into bad actors. It turns them into unintentional insider threats by placing them in systems they don’t control, aren't secure, and don’t fully understand. Organizations that recognize this and respond with better tools and smarter governance reduce risk without sacrificing speed or innovation.
