While most organizations have different systems, there are many ways that companies are alike. Consider your regular enterprise that has its standard meetings and reviews. Everything seems to be coming together until you hit the official inventory and see that a certain team has been paying for an AI transcription service on a corporate card, a few developers have spun up cloud instances to test an application, and a regional office started using their preferred file-sharing platform because the approved system was too slow.

Suddenly, there are a bunch of IT platforms and processes in your organization that lack security approval or authorization. However, none of these started with bad intentions, but were put in place to simply get the job done. This is the central problem with shadow IT in 2026. Today, the amount of tech that your IT team officially manages can be substantially smaller than the amount your business actually uses.

The trend is becoming more significant as enterprises move deeper into cloud computing, hybrid infrastructure, AI adoption, and modernization programs. Shadow IT is no longer simply an issue of employees installing unauthorized software; it’s become an infrastructure, security, financial, and operational governance problem. Today, we’ll be looking at the key causes, risks, and guiding frameworks you need to navigate the growing shadow IT landscape. So, what is shadow IT?

What Is Shadow IT in 2026?

At its simplest, shadow IT refers to any technologies used by an organization without the knowledge, approval, or oversight of the IT department. However, the definition has expanded considerably with the evolution of technology. While traditional shadow IT might have simply meant an employee installing an unauthorized application, today, examples can include unapproved SaaS subscriptions, personal cloud storage accounts, or the use of AI assistants and generative AI platforms.

It’s important to note that shadow IT is in no way intentionally malicious most times, serving to simplify operations for employees in most cases. In many ways, shadow IT can streamline processes, which is why it's become so popular. According to Gitnux, 45% of organizations allow their employees to buy and use software without IT approval, while 61% admit that they have unmanaged SaaS running in their environment.

However, there needs to be limits at some point, which is why companies need stricter frameworks in place. But to address the symptoms without addressing the cause is not a good enough fix. This changes the main question for IT leaders. Instead of asking how to stop employees from using unapproved technologies, enterprises should be asking why employees feel that they had to go around the official processes in the first place.

At its root, shadow AI adoption is often the result of employees not having a sanctioned way to use AI tools productively. Rather than only restricting access, organizations can reduce this risk by building AI-ready infrastructure internally. This gives teams a governed, compliant environment for AI workloads instead of pushing them toward ungoverned external tools.

Five Reasons Shadow IT Is Accelerating in 2026

Now, when it comes to shadow IT, companies immediately jump to stopping unauthorized tech usage first. However, the issue is not with the platforms themselves, but rather the conditions that made them necessary. Figuring out that distinction changes your organization’s entire strategy to dealing with shadow IT. If teams create their own cloud environments because central IT takes too long, wouldn’t it make more sense to simply improve the approval process?

While approved platforms need to abide by the company’s structured security, access, and control policies, it’s important to understand that technology governance works best when it aligns with how businesses actually operate. These are some of the reasons why shadow IT seems to be gaining traction in 2026:

The VMware Migration Wave Is Creating New Gaps

Large-scale infrastructure transitions are rarely purely technical projects. They affect budgets, operating models, skills, contracts, and long-term architecture. The well-known VMware transition toward subscription licensing and its simplified portfolio changed the game for many customers. When Broadcom announced the end of perpetual VMware licenses and a move toward subscription offerings, customers quickly began to look for alternatives.

However, not every customer could seamlessly migrate so easily. This period of uncertainty creates the ideal environment for shadow IT to thrive, giving different teams the ability to choose their own platforms and systems before the organization settles again. The result is not necessarily one dramatic unauthorized system, but rather a wave of fragmentation.

This is also why choosing the correct migration path is important. Organizations that can move to a new platform with clear, structured options are less likely to see teams route around the transition altogether.

AI Has Made Shadow IT Easier Than Ever

The age of AI has dramatically reduced the friction involved in adopting new technology. Today, employees no longer need to request a server, install software, or wait for a procurement cycle to experiment with a new AI platform. All you need is an account, and you’re ready to go.

This creates a whole new subcategory of shadow AI. Research has shown that almost 38% of workers share sensitive work information with AI without their employer’s knowledge, risking inadvertently leaking confidential information, intellectual property, or customer data.

IBM’s 2025 Cost of a Data Breach report also revealed that 63% of the breached organizations they studied lacked AI governance policies, and only 37% had approval processes or oversight mechanisms in place. While AI tools may be useful in some capacity, the governance around those platforms needs to be regulated and airtight.

Multi-Cloud and Hybrid Infrastructure Multiply Visibility Gaps

Today, companies rarely operate a single, simple infrastructure stack. They have traditional data centers, private and public clouds, SaaS platforms, colocation facilities, and specialized environments for AI or analytics. Today, the global multi-cloud management market size is projected to grow to US$ 85.89 billion by 2034.

Every additional environment creates another place where technology can appear. While team A deploys workloads with one cloud platform, team B might use a different one. Using multi-cloud platforms is not inherently wrong, but the challenge we have to face is that visibility does not automatically scale with infrastructure complexity.

Speed and Governance Are Often Working Against Each Other

Many times, official and approved processes are too slow to keep up with the workload demands. This is where shadow IT mostly thrives. If the official process is slow while the unauthorized platform is instant, then employees have a strong incentive to choose the latter. Research by WalkMe showed that enterprises have lost over $104 million in 2024 alone due to underutilized technology and poor productivity practices.

This is also why an effective shadow IT policy cannot focus on simply banning other tech. Organizations must examine the motivations behind these choices. If the approved route takes six weeks and the unofficial route takes six minutes, governance will eventually lose.

Distributed Workforces Have Changed the Control Model

The hybrid and remote work models have permanently changed how companies operate. Today, employees can work from anywhere, with teams collaborating across countries and continents alike. As a result, central IT can no longer assume that everything happens inside a corporate network.

This makes identity, SaaS management, cloud governance, and centralized visibility increasingly important. The more distributed the workforce becomes, the more important it is for governance to operate through policy and visibility rather than physical proximity.

Shadow IT has evolved across sectors to streamline and simplify processes in many cases. However, unapproved platforms still pose some serious security risks at the end of the day, some that you may not have even considered.

The Real Risks of Shadow IT: Beyond the Obvious

Shadow IT is a security risk in general, but many organizations seem to ignore the subtle yet insidious ways shadow IT can be used to debilitate your security infrastructure from inside. While you might think the main security risks associated with shadow IT boil down to privacy, the consequences can be much deeper. Instead of thinking one step ahead, business leaders need to think 5 steps ahead and consider what happens when unauthorized technology becomes embedded in business operations. These are a few of the security risks of shadow IT in the modern age:

• Data Exposure and Compliance Gaps: Naturally, any unsanctioned application may not meet enterprise requirements for encryption, data residency, retention, access control, or auditability. This creates regulatory exposure even without an obvious cyber-attack. For multinational enterprises, this becomes especially complicated when information crosses jurisdictions through external SaaS platforms, APIs, or cloud services.
• An Uncontrolled Attack Surface: Every unmanaged workload is another potential entry point. An employee-created cloud instance may not receive the same patching, vulnerability scanning, identity controls, or monitoring as centrally managed infrastructure. The system does not have to be actively dangerous to become a security problem. It only needs to be forgotten.
• Data Integrity Failures: While security teams often focus on whether shadow systems expose data, IT leaders should also be asking whether those systems produce wrong information. Shadow IT creates silos in which conflicting versions of reality may exist. One database might be updated while another is not, leading to faulty data.
• Invisible Costs: At the end of the day, shadow IT also undermines financial governance. While your company has a software platform contract in place, individual departments could choose to purchase competing subscriptions. Those costs can be small individually but significant collectively, and may lead to duplicated cloud storage, unused instances, overlapping security tools, and forgotten subscriptions. According to IBM's 2025 Cost of a Data Breach Report, shadow AI incidents average $4.63 million per breach, $670,000 above the baseline for standard breaches.
• Shadow IT Is a Migration Complexity Multiplier: This is particularly important during VMware migration. A company might officially migrate workloads from VMware to another Hypervisor or Hyperconverged Infrastructure platform, but what happens to the unofficial workloads? They may remain on legacy infrastructure, some may be moved to public cloud independently, and others may be rebuilt by application teams. Now, IT is not just managing one migration, but also an undocumented infrastructure map. This increases the risk of missed dependencies, inconsistent security controls, unsupported workloads, and unexpected downtime.

So, how do you manage such an invasive and potentially complex landscape? Well, you do it with a strategic and productive approach.

A Governance Framework: Managing Shadow IT Without Killing Innovation

Now, it’s important to understand that the goal of ideal shadow IT governance should not be to eliminate every unauthorized technology purchase, but to create an environment where employees streamline processes without creating invisible risk. You have to be realistic about your expectations and your goals. A practical framework for this has four stages:

Stage 1: Discovery

You cannot govern what you cannot see. This is why you have to establish visibility before anything else. Your organization needs to look at network discovery, cloud asset inventories, SaaS management platforms, CASB tools, and identity and access data. The objective is to find out what is being run, who is running it, and for what purpose. You do not begin by shutting things down; you begin by understanding the environment.

Stage 2: Classify

Now, not all tools are built the same way and therefore do not have the same security risks attached. A marketing employee using an unapproved presentation tool is not the same as a developer dumping private information into ChatGPT to create code. Your level of risk should be classified according to relevant factors.

Stage 3: Respond

If employees consistently bypass IT, the organization should examine the process before blaming the employees. Create a fast approval route for common, low-risk technologies. For example:

Low-risk request → automated policy check → approved

Medium-risk request → expedited security review → approved with controls

High-risk request → formal architecture and security assessment

This turns governance from a roadblock into an accelerator. The best shadow IT policy is not necessarily the strictest one. It is the one employees can realistically follow.

Stage 4: Unify

Remember, centralized management is an important part of controlling infrastructure sprawl. The more fragmented the infrastructure becomes, the harder it is to understand workloads, resources, policies, and operational dependencies.

A centralized cloud and infrastructure management layer can provide a consistent operational view across environments. This is particularly valuable during virtualization modernization, where teams may otherwise be forced to manage different tools and processes for different infrastructure stacks.

Ultimately, your plan to deal with shadow IT should be used as an opportunity for insight into how your company works best. Every unauthorized application tells your IT team something about unmet demand. The organizations that learn from these signals will be better positioned to govern technology without suppressing innovation.

How Sangfor Helps Organizations Regain Control

For most companies, addressing shadow IT is ultimately an infrastructure-management challenge as much as a security challenge. Sangfor Technologies is a global provider of cloud computing, cybersecurity, and IT infrastructure solutions, serving more than 100,000 customers worldwide, including Fortune Global 500 companies and organizations across multiple industries.

Sangfor’s approach can easily align with the governance framework we’ve discussed in this article, ensuring reduced infrastructure fragmentation and providing a structured path for organizations.

Sangfor’s Cloud Platform (SCP) acts as the centralized management hub, providing visibility and control across virtualization, private cloud, and hybrid environments. Rather than forcing administrators to operate every infrastructure component as an isolated system, this centralized management provides a more consistent operational experience, especially for organizations managing private cloud, virtualization, and hybrid environments.

For VMware-trained teams, the centralized-management concept is also familiar. VMware environments commonly use vCenter Server as a central management layer, while Sangfor uses SCP.

Sangfor also provides a structured migration path via Sangfor HCI (full-stack) or aSV as a standalone hypervisor, which can help to reduce the transition uncertainties that often contribute to the use of shadow IT. This is also ideal for companies that don’t want to replace their entire infrastructure stack at once.

Sangfor Hyper-Converged Infrastructure (HCI) also integrates infrastructure components into a unified platform. Sangfor's published VMware migration architecture also maps these components against familiar VMware technologies, including vSphere, vSAN and NSX.

Every additional infrastructure silo introduces another management interface, another operational process and another potential visibility gap. A unified HCI approach can reduce that fragmentation and make it easier for infrastructure teams to establish consistent operating practices.

In a similar vein, Sangfor aSAN is a fully integrated, distributed software-defined storage layer built into the HCI stack, whereas VMware vSAN is typically licensed and deployed as an add-on component. Sangfor’s aNET also offers built-in, visualized network virtualization, while VMware NSX offers advanced capabilities that generally require additional licensing and specialized expertise.

The important point is not simply whether one product has a feature that another product lacks; it’s whether the organization can still operate with the same architectural consistency, security, and predictability. That is exactly where Sangfor’s infrastructure simplification can help reduce the conditions that produce shadow IT.

It’s also important to understand that infrastructure governance does not stop at virtualization. If a workload is migrated successfully but cannot be recovered after a ransomware attack, hardware failure, or operational mistake, the organization has not achieved resilience.

Sangfor works with ecosystem partners including Veeam for backup, recovery, and data resilience, and works with Cohesity to combine Sangfor infrastructure with their data security and resilience capabilities for hybrid and multi-cloud environments.

For the modern enterprise, this ecosystem approach is crucial because migration should not create another isolated technology stack. The ultimate goal is a governed infrastructure environment that can connect with the wider enterprise data-protection ecosystem.

Conclusion

At the end of the day, shadow IT is not going away. In fact, the technologies driving digital transformation, like cloud platforms, AI, SaaS, and distributed infrastructure, are all making it easier than ever for employees to solve problems outside traditional IT channels. While this does not make innovation the enemy, it does make visibility and governance more important.
