Shadow IT: Risks, Examples, and How to Manage It

Informatec Digital » Resources » Shadow IT: Risks, Examples, and How to Manage It

Shadow IT has crept into almost every organization without making a sound: cloud applications contracted with a company card, WhatsApp groups for work-related matters, personal storage accounts used for client files… All of this is part of a reality that grows more and more each day and that, if not managed, can become a serious headache.

At the same time, this "unofficial" IT also arises from very real needs: employees who want to work faster, collaborate better, or compensate for shortcomings in corporate tools. The problem isn't so much its existence, but rather that it operates outside the radar of the IT and security departments. A thorough understanding of what it is, why it emerges, what risks it entails, and how to manage it is key for any organization that wants to be agile without losing control.

What is shadow IT and why does it exist?

When we talk about shadow IT, we're referring to the use of software, hardware, cloud services, applications, or devices within a company that haven't been approved, monitored, or, often, even known by the IT department. These can range from a simple free task management app to a complete cloud-based collaboration platform contracted by a business unit.

This technology can be installed on corporate computers, personal laptops, personal mobile devices (BYOD), tablets, USB drives , or directly on external cloud services. The common denominator is that it is used for work purposes, but outside the organization's formal procurement, security, and compliance processes.

In recent years, this phenomenon has skyrocketed for several reasons: the consumerization of technology (powerful, inexpensive, and easy-to-use tools available to everyone), the explosion of SaaS, widespread remote work, and the ability to provision cloud services with just a few clicks. According to various studies, around 41% of employees were already using solutions outside of IT control in 2022, and this figure is expected to continue rising.

The concept of shadow IT doesn't inherently have a positive or negative connotation. The problem is that, being outside the scope of the IT department, it doesn't go through the security, licensing, and governance controls that apply to the company's official technology, opening the door to cybersecurity, compliance, cost, and operational risks.

Common examples of shadow IT

Shadow IT is not an abstract concept: it manifests itself in very concrete, everyday behaviors. Understanding these examples helps to better identify it and design realistic policies.

The first category consists of cloud applications that users access directly from the corporate network or from their personal devices: project management tools such as Trello or Asana, storage solutions such as Google Drive or Dropbox, alternative productivity suites, department-specific CRMs, etc.

Secondly, we have Software as a Service (SaaS) contracted by business units without going through purchasing or IT: licenses for marketing tools, analytics platforms, design or editing solutions, non-certified video conferencing applications, etc. These are usually paid for with corporate credit cards used by the unit managers themselves or through personal subscriptions that are later reimbursed.

Another common form is the use of personal devices at work (BYOD) without proper management: personal mobile phones used for corporate email, personal tablets with customer data, home laptops connected to the organization's network, unencrypted USB drives to transfer sensitive information… All of this increases exposure without IT having any real control.

This also includes software installed by the employee on their work computer: browser plugins, productivity add-ons, development tools downloaded by the technicians themselves, unauthorized messaging or video calling applications, and even custom code executed on the corporate laptop outside of official repositories.

Finally, we must not forget the use of personal communication platforms such as WhatsApp, Telegram, Signal or Discord to deal with work matters, as well as the use of personal email accounts to send client documentation or share files with suppliers, something that makes that data completely opaque to the organization.

Why is IT spreading so much in the shadows?

Shadow IT doesn't appear randomly, but rather as a response to a combination of organizational, technological, and human factors. If we want to manage it effectively, we must address these root causes.

One of the most significant issues is the perception of slowness and rigidity within the IT department . When the approval processes for new tools are lengthy, bureaucratic, or opaque, employees feel that requesting something new is nearly impossible, especially if they have tight deadlines to meet.

Dissatisfaction with official solutions also plays a role . Unintuitive, limited, or poorly adapted corporate tools lead teams to seek better alternatives. If a department discovers that a particular app can make them work twice as fast, the temptation to adopt it independently is enormous.

The ease of access to technology itself plays a decisive role. Today, with a simple credit card and a little know-how, anyone can set up advanced cloud services for collaboration, task management, software development, or large-scale data storage, without ever having to ask IT.

Added to all this is a lack of awareness of the risks . Many employees use these solutions with good intentions and without malice, believing that "nothing will happen" to sharing documents from their personal account or installing a free app that has been recommended to them, without being aware of what it can imply in terms of data leaks, malware, or regulatory non-compliance.

Finally, more human factors come into play, such as a lack of a culture of trust and communication . Some people, for fear of being seen as problematic or admitting that a process isn't working, choose to "make do" on their own with unapproved tools rather than openly raise the need for change.

Potential benefits of shadow IT

Although it is often associated with problems, shadow IT also has a positive side that should be recognized in order to channel it properly instead of trying to eradicate it by force.

In many cases, these tools provide much faster access to solutions that address specific, day-to-day problems. A team can start working with a new application in a matter of hours, without having to wait weeks for a formal acquisition and deployment process to be completed.

Shadow IT is also a source of innovation and experimentation . Users explore emerging technologies, test new ways to collaborate or automate tasks, and sometimes discover solutions that can later be officially adopted because they provide clear value to the entire organization.

Another clear benefit is the improvement in employee productivity and comfort . Working with tools that fit their workflows perfectly, that they know well, and that they can customize, usually translates into less friction, less wasted time, and more focus on value-added tasks.

We mustn't forget the psychological factor: allowing some flexibility in the tools used fosters more empowered and self-sufficient teams , with a culture of resourcefulness and independent problem-solving. When properly managed, this can be very positive for the company's agility.

However, all these benefits usually come with an important catch: if this technology is not subject to proper controls, the temporary gain in efficiency can easily end up being paid for in the form of security incidents, regulatory sanctions, data chaos, or hidden costs.

Main risks of shadow IT

The other side of the coin of shadow IT is the set of risks it introduces. Many of these are not apparent at first, but they accumulate and can explode at the worst possible moment.

The first and most visible consequence is the increased attack surface . Every new unauthorized application, every external cloud service, every personal device connected to the network is an extra point that cybercriminals can try to exploit. Because they are not integrated into the corporate security architecture, they often represent the perfect backdoor.

Related to the above, shadow IT increases vulnerabilities and the potential for malware . Many free or little-known applications lack robust security mechanisms, are updated late, or contain serious bugs. In the case of mobile devices and third-party apps, studies have shown that a very high percentage have security flaws that attackers can exploit.

Another critical risk is the loss, leakage, or improper exposure of data . When employees store corporate information on personal accounts, with unvetted vendors, or on unencrypted devices , the organization loses visibility and control over that data. If just one person leaves the company or loses a device, all the information stored on it is lost.

Shadow IT also greatly complicates regulatory compliance . Regulations such as GDPR, HIPAA, PCI DSS, and standards like NIST require knowing where data resides, how it is protected, and who has access to it. If some of that information moves through unknown channels, ensuring compliance is virtually impossible, which can lead to financial penalties, legal obligations, and serious reputational damage.

From an operational perspective, the proliferation of unauthorized tools leads to inefficiencies, silos, and fragmented workflows . Each team may end up using its own combination of apps to manage tasks, communicate, or share files, hindering interoperability, increasing duplication, and making it very difficult to have a unified view of the data.

The impact on costs should not be overlooked. While in the short term it may seem like savings are being made by switching from purchasing a large corporate solution to using several cheap or free services, in the long run shadow IT often generates hidden expenses : duplicate subscriptions, unused licenses, downtime due to incidents, extra support and remediation effort, lock-ins with non-certified providers, etc.

Visibility, control, and compliance issues

A side effect of shadow IT is that the IT department loses its role as the central source of truth about the organization's technology. If it doesn't know what's being used, where the data resides, or what dependencies exist between systems, it becomes very difficult to design a coherent strategy for security, continuity, and evolution.

The lack of visibility has multiple consequences. On the one hand, it prevents the protection of what cannot be seen : monitoring, backup, encryption, or incident response solutions do not cover systems that are not even listed in the official inventory. On the other hand, it generates inconsistencies in the information, since several versions of the same data may exist scattered across different, unconnected tools.

In the area of ​​compliance, the shadow environment complicates both evidence management (logs, access histories, change traceability) and the response to audits or incidents. If a regulatory authority requests proof of where certain personal data is stored, who has processed it, and with what security measures, the gaps left by uncontrolled IT can be enormous.

There is also a direct impact on the company's ability to manage the data lifecycle : retention, archiving, secure destruction, etc. If some information is stored in unofficial repositories, when an employee leaves or when certain information needs to be purged, it's easy for live copies to remain, with the consequent risk.

Finally, the loss of control creates difficulties when planning investments and resources . Corporate licenses for underutilized tools may be being paid for while certain teams pay for similar tools on their own, or functionalities may be duplicated without realizing it. Without a complete picture, optimizing IT spending becomes nearly impossible.

How to detect shadow IT in your organization

The first step in managing shadow IT is not prohibition, but gaining visibility . Many organizations are surprised when, by doing this exercise, they discover dozens or hundreds of services that no one had formally declared.

A basic technique involves conducting regular network and endpoint audits to identify unauthorized applications, cloud services, and connections. This includes reviewing software installed on computers, browser plugins, mobile apps connected to corporate email, and traffic patterns to SaaS domains.

It's also very useful to analyze expense and purchase records for payments to technology providers that don't go through the usual channels. Credit card subscriptions to cloud services, recurring small charges, or software invoices issued to specific departments can be a clear sign of shadow IT.

Another detection method involves integrating information from identity and SSO providers (such as Azure AD, Google Workspace, and others) to see which applications users are accessing with corporate credentials. While not all of these applications are approved, this layer of visibility helps map the organization's activity patterns.

There are also specific Shadow IT detection tools and CASB (Cloud Access Security Broker) that monitor traffic to cloud services, classify applications according to their risk level, and allow for the automated identification of new additions in a matter of seconds, generating alerts when something unauthorized appears.

Finally, detection shouldn't be solely technical. It's crucial to foster a culture of transparency where employees are encouraged to discuss which tools they use and why, without fear of reprimand. Internal surveys, interviews with department heads, and open communication channels can uncover more shadow IT than many scanners.

Best practices for preventing and controlling shadow IT

Once the overall picture is understood and what lies beneath the surface is revealed, it's time to design a strategy to reduce risk without stifling innovation . The key is to combine processes, technology, and culture.

From an organizational standpoint, improving collaboration between IT and business units is crucial . Instead of acting as a mere "no" department, IT should sit down with teams, understand their real needs, and propose safe alternatives that address them. When users feel heard, they are less likely to look for shortcuts.

It also helps a lot to offer a clear, up-to-date, and easy-to-consult catalog of authorized services and applications . If employees know which tools they can use for each use case (collaboration, project management, file sharing, messaging, etc.), the temptation to leave the company is reduced.

From a technical point of view, it is advisable to deploy mobile device management (MDM) solutions and robust BYOD policies that allow control over which apps are installed on personal devices that access corporate data, apply encryption, separate personal and work spaces, and block the use of unauthorized services.

In development environments, it is critical to tackle so-called shadow code by integrating security analysis tools (SAST, DAST, IAST) into the application lifecycle, reviewing which libraries and frameworks are used, and ensuring that all code that reaches official repositories has been evaluated and documented.

Access controls and the principle of least privilege must also extend to the cloud: defining who can provision new services, with what default security configurations, how resources are labeled to track them, and what requirements they must meet before going into production.

On the other hand, automating alerts and responses to anomalous behavior is highly effective : detecting subscriptions to new SaaS services, spikes in data transfers to external providers, intensive use of unclassified apps, etc. The sooner a new instance of shadow IT is detected, the more time there is to address it.

Training and awareness are essential pillars. It's not enough to launch a policy and expect it to be followed: you have to explain clearly and practically what shadow IT is, what risks it entails, what secure alternatives exist, and how to request new tools. Regular workshops, training modules, simulations, and internal campaigns can make all the difference.

Finally, it is advisable to conduct recurring IT audits , reviewing both official and undiscovered assets, assessing their fit with security and compliance policies, and defining regularization plans: from formally integrating those tools that add value, to removing those that pose an unacceptable risk and proposing suitable replacements.

Managing IT behind the scenes isn't about micromanaging employees or imposing strict control over their every click, but rather about channeling their initiative, reducing blind spots, and balancing productivity and security . The more transparent the communication, the more agile the process for approving new solutions, and the clearer the rules of engagement, the less need people will have to "go behind the scenes" to do their jobs well.
