Shadow IT: Recognizing Risks, Utilizing Benefits, and Managing Efficiently

In today's digitalized business world, IT is no longer solely the domain of a specialized department. Employees across all areas use software and digital tools daily to accomplish their work. But what happens when they turn to unapproved applications without the knowledge or consent of the IT department? This phenomenon – known as Shadow IT – is ubiquitous in modern companies and presents a complex challenge for IT teams.

What is Shadow IT and Why Do Employees Use It?

Shadow IT refers to all IT components, activities, and solutions that are used without the approval or knowledge of the IT department. The term encompasses hardware, software, cloud services, and apps used outside the official IT infrastructure. Typical examples include:

• Unauthorized cloud storage services such as Dropbox, Google Drive, or Microsoft OneDrive, where company data is stored
• Messaging and collaboration apps like WhatsApp, Slack, or Microsoft Teams that are used without official approval
• Productivity tools like Trello, Asana, or Monday.com, independently implemented by teams
• Personal devices (Bring Your Own Device) connected to the company network without appropriate security policies
• Web-based SaaS applications used without involving the IT department

These unofficial solutions often arise from legitimate needs: employees look for more efficient ways to get their work done when officially provided IT systems are perceived as inadequate or approval processes take too long.

The Prevalence of Shadow IT in Companies

The use of Shadow IT is not uncommon – in fact, it is widespread in most companies. According to a study by Stratecast (Frost & Sullivan) in collaboration with McAfee, 80% of employees report using applications at work that have not been approved by the IT department. The same study shows that over 35% of all SaaS applications in companies are purchased without IT department oversight.

This uncontrolled use of IT resources is particularly problematic in the context of an intensifying cyber threat landscape. According to current data from Statista, around 58% of surveyed companies in Germany were victims of cyber attacks at least once in 2023. The damage to the German economy through data theft, industrial espionage, or sabotage reached a record high of over 200 billion euros.

Small and medium-sized enterprises in particular are in the crosshairs of cybercriminals, as phishing or ransomware attacks can have existentially threatening consequences for them. In the era of digital transformation and remote working, the use of unauthorized IT solutions has significantly increased, further elevating security risks.

Risks of Shadow IT

Unauthorized applications and services cannot be monitored or secured by the IT department. These solutions may be vulnerable to security gaps that cybercriminals can exploit for attacks to steal confidential information or introduce malware. For example, if employees do not update critical software, the security risk of data breaches increases significantly. Beyond security risks, there are other challenges in this context.

1. Compliance Violations

The use of Shadow IT can lead to non-compliance with industry-specific and general regulations such as GDPR. This can result in legal consequences and fines, especially when sensitive data is involved. Data Loss Prevention (DLP) systems often cannot cover these risks if they lie outside the controlled IT infrastructure.

2. Lack of Control

When company data is stored in unauthorized cloud systems, this can lead to data loss, as these systems may not be integrated into the usual backup and disaster recovery processes. IT teams lose oversight and management capabilities over this data.

3. Hidden Costs

Parallel IT solutions lead to data silos and compatibility problems, which complicates collaboration. Additionally, hidden costs arise from redundant acquisitions when different departments purchase similar tools that already exist as approved alternatives.

4. Compliance with Security Standards

Companies with certified management systems (such as ISO 27001) risk losing their certifications if these problems are not controlled. Their Zero Trust Security models can be compromised by uncontrolled Shadow IT.

Benefits of Shadow IT

Despite the risks, Shadow IT also brings benefits that companies can utilize:

Efficiency Increase

The immediate implementation of tools without lengthy approval processes can increase efficiency. Employees often choose solutions that optimally fit their specific work requirements and help to complete tasks efficiently.

Innovation and Agility

Employees who independently search for solutions show commitment and can bring innovative approaches to the company. This bottom-up innovation can provide valuable impulses for the further development of the official IT infrastructure and the introduction of new technologies.

Talent Attraction and Retention

Especially in IT-related industries, qualified employees appreciate the flexibility to work with familiar and modern tools. An overly restrictive IT policy can deter talented professionals.

Strategies for Handling Shadow IT

IT managers face the task of finding a middle path that ensures necessary security governance without hindering productivity. This requires a rethinking of IT culture: away from a primarily controlling function toward a partnership approach that takes the needs of the departments seriously while ensuring company security. The following approaches should not be considered in isolation, but as part of a holistic IT governance strategy.

1. Identifying and Analyzing Shadow IT

The first step in dealing with Shadow IT is recognizing and understanding the current state. For this reason, those responsible should conduct regular IT audits to identify unauthorized software and hardware. Additionally, the use of monitoring solutions and Endpoint Detection and Response (EDR) helps to detect suspicious network traffic early and eliminate potential security risks.

A deeper analysis of the reasons for using Shadow IT can help: anonymous employee surveys could be conducted, which then provide valuable insights into the actual needs of the employees. Particularly effective is the implementation of Cloud Access Security Brokers (CASBs), which can monitor and control unauthorized cloud applications.

2. Developing a Clear Shadow IT Policy

An effective guideline for handling Shadow IT should consider several central aspects. Fundamental is a clear definition of allowed and disallowed applications that is accessible and understandable to all employees. Transparent processes for requesting new software through, for example, a self-service portal reduce employees' motivation to act outside the guidelines. Additionally, clear guidelines for the use of personal devices in the company network (BYOD) must be established. This can be supplemented by training concepts that sensitize employees to potential security vulnerabilities.

3. More Flexible and Faster IT Provisioning

To prevent the emergence of Shadow IT, companies should potentially optimize their IT provisioning processes fundamentally. Experience shows that shortened approval times for new software prevent employees from turning to other solutions out of impatience. Regular updating of the official software catalog (service portfolio) can ensure that the offered solutions meet current requirements. Particularly user-friendly is the establishment of a self-service portal for common IT requests, giving employees quick access to needed resources.

4. Technical Measures for Risk Minimization

In parallel, technological solutions play a decisive role in reducing general risks. For example, Cloud Access Security Brokers (CASBs) are an important technology for monitoring and controlling applications by analyzing data traffic between company devices and cloud services. Complementing this, Data Loss Prevention (DLP) systems protect sensitive data from unintentional or unauthorized access. Comprehensive security platforms ensure the protection of all devices in the company network. These measures should be rounded off by robust data encryption and strict access controls for company data.

5. Cultural Change and Training

Nevertheless, sustainable handling of Shadow IT requires a fundamental cultural change in the company. Central is the promotion of an open dialogue about IT needs between IT departments and specialized departments, creating mutual understanding. Regular training on IT security and compliance sensitizes employees to potential risks and imparts competence to act. In the long term, a culture of shared responsibility for data security should be established, in which every employee contributes to IT security. Particularly motivating is the recognition and integration of innovative ideas from employees into the official IT strategy.

From Challenge to Opportunity: Shadow IT as an Innovation Driver

Instead of viewing Shadow IT merely as a threat, companies can use it as a valuable source of innovation. The progressive approach begins with the systematic observation of already used Shadow IT tools to identify trends and unfulfilled needs in the organization. In parallel, it is recommended to create a structured process through which employees can request new tools in an uncomplicated way. Particularly promising is the regular evaluation of popular Shadow IT applications for potential official implementation. If an unofficially used solution proves to be secure and valuable, it can be incorporated into the official IT portfolio after appropriate testing.

Some companies go a step further and set up an Innovation Lab where new technologies can be safely tested under controlled conditions. In this protected space, employees can experiment with innovative solutions without endangering the company network, thereby constructively channeling the creative energy of the workforce.

Modern IT Management Solutions for the Administration of Shadow IT

An effective strategy usually includes modern IT management systems that provide a transparent overview of all company resources while enabling flexible work processes. With a platform like equipme, IT managers can create a complete digital twin of their organizational and IT structure, making all structural connections visible as a virtual representation. This transparency makes it possible to centrally manage and continuously monitor all IT assets, allowing unauthorized components to be detected more quickly.

At the same time, procurement processes for new software and hardware can be automated and significantly accelerated, eliminating a main motivation. Particularly valuable is the ability to transparently track the complete lifecycle of all IT components. Not least, the central management of approved software and hardware greatly increases visibility and ensures compliance. Through the combination of clear guidelines, technical measures, and a flexible IT management platform, companies can utilize the benefits of Shadow IT while effectively minimizing the associated risks.
