What Is Shadow IT and Why Is It a Hidden Threat for Organizations?
Imagine this: an employee in the marketing team needs to share large video files quickly with an external agency. The company-approved file-sharing system is slow and has a tiny storage limit. Frustrated, the employee signs up for a free Dropbox or Google Drive account using their work email and starts using it daily. Nobody in IT knows about it. This simple act of trying to get work done faster is a perfect example of shadow IT. Shadow IT sounds mysterious and dangerous, but it is actually very common. In most companies, employees use tools, apps, or cloud services that the IT department has never approved or even heard about. While these tools often make people more productive in the short term, they create serious hidden risks for the entire organization. In this post, we will explain exactly what shadow IT is, why employees use it, what dangers it brings, and most importantly, how organizations can manage it without killing innovation.

What Is Shadow IT?
Shadow IT refers to any software, hardware, or cloud service that employees use to do their jobs without official approval or oversight from the IT department.
It includes:
- Cloud storage like personal Dropbox, Google Drive, or OneDrive accounts
- Collaboration tools such as Slack, Trello, or Notion created by individual teams
- Messaging apps like WhatsApp or Telegram used for business chats
- Free project management tools (Asana, Monday.com free tiers)
- Personal laptops, USB drives, or even home printers used for work
- Browser extensions that handle passwords or automate tasks
The key point is that IT has no visibility or control over these tools.
Why Does Shadow IT Happen?
Employees do not create shadow IT to cause trouble. They do it because they want to work better and faster. Common reasons include:
- Official tools are slow, complicated, or missing key features
- IT approval processes take weeks or months
- Employees are not aware that certain tools need approval
- Remote and hybrid work makes personal devices and apps more tempting
- Free or low-cost SaaS (Software as a Service) tools are extremely easy to sign up for
In short, when there is a gap between what employees need and what IT provides, people fill that gap themselves.
Common Examples of Shadow IT
- A sales rep uses a personal Zoom account instead of the company’s limited Webex plan
- The design team shares files via WeTransfer because the corporate system caps file size at 25 MB
- An executive installs ChatGPT Plus and feeds it customer data
- Developers spin up personal AWS or Azure accounts to test ideas quickly
- Someone uses a personal password manager to store company credentials
The Hidden Risks of Shadow IT
At first glance, shadow IT looks harmless or even helpful. But the risks are real and often invisible until something goes wrong.
- Data leaks: Files stored in unapproved cloud services can be accidentally shared publicly or hacked.
- No backups: If an employee leaves and their personal Dropbox is deleted, company files disappear.
- Compliance violations: Industries like healthcare (HIPAA) or finance (GDPR, PCI-DSS) can face huge fines if data ends up in non-compliant tools.
- Security gaps: Many free tools lack enterprise-grade encryption, audit logs, or two-factor authentication enforcement.
- Shadow costs: Dozens of $10/month subscriptions across teams can add up to thousands of dollars without anyone noticing.
- Integration problems: When the company finally chooses an official tool, migrating years of data from shadow systems becomes a nightmare.
Shadow IT By the Numbers
| Statistic | Source (Recent Studies) | Key Takeaway |
|---|---|---|
| 80-90% of employees admit using unapproved SaaS apps | Gartner, 2024 | Almost everyone does it |
| Average company uses 254 SaaS applications | Productiv, 2025 report | Most are unknown to IT |
| Companies underestimate shadow IT by 10-20 times | McAfee & Forrester | IT thinks there are 30-40 apps; reality is 400+ |
| Shadow IT causes 40% of data breaches in some industries | Verizon DBIR 2024 | It is a top attack vector |
| Only 12% of companies feel they have full visibility | Cloud Security Alliance 2025 | Most organizations are blind |
How to Detect Shadow IT
You cannot manage what you cannot see. Practical detection methods include:
- Network monitoring tools (CASB - Cloud Access Security Broker)
- Expense report audits (look for recurring charges from Zoom, Slack, Canva, etc.)
- Endpoint management solutions that list installed software
- Regular employee surveys ("What tools do you use every day?")
- Cloud discovery tools such as Microsoft Defender for Cloud Apps or Netskope
How to Manage Shadow IT Safely
The goal is not to ban everything (that pushes shadow IT further underground). Instead, adopt a proactive approach:
- Create a fast approval process: Let teams request new tools and get answers within days, not months.
- Offer better alternatives: If people love Notion, buy the enterprise version instead of forcing SharePoint on them.
- Educate employees: Run short lunch-and-learn sessions about risks and approved options.
- Implement a "bring your own app" policy with clear security requirements.
- Use automation: Tools like Torii, Zylo, or Blissfully can automatically discover, assess, and manage SaaS spend.
- Celebrate responsible usage: Publicly thank teams that ask for approval before adopting new tools.
Conclusion
Shadow IT is not going away. The explosion of easy-to-use cloud tools and the demand for speed in modern work ensure that employees will always find ways to get things done faster.
The real danger is not the tools themselves, but the lack of visibility and governance around them. Organizations that treat shadow IT as an enemy end up with more of it. Companies that treat it as a signal (employees telling you the approved tools are not good enough) can turn a risk into an opportunity for improvement.
Start by discovering what is already happening in your organization, talk openly with your teams, and build processes that balance security with productivity. When you do that, shadow IT stops being a hidden threat becomes a helpful spotlight showing exactly where your official IT strategy needs to evolve.
What exactly counts as shadow IT?
Any hardware, software, or cloud service used for work purposes without formal IT approval and oversight. This includes personal cloud storage, free collaboration apps, messaging platforms, and even personal devices.
Is using personal Gmail for work considered shadow IT?
Yes. Sending or receiving work emails or attachments through a personal Gmail account bypasses corporate security controls and archiving.
Why do employees create shadow IT if they know it is risky?
Most employees do not realize the risks, or they feel the official tools slow them down too much. They prioritize getting the job done over theoretical security concerns.
Is ChatGPT considered shadow IT?
Yes, if employees use the public ChatGPT website and input company data without IT approval and without an enterprise agreement.
Can shadow IT ever be a good thing?
Absolutely. Many great tools (Slack, Zoom, Trello) started as shadow IT in companies before becoming officially adopted. It often reveals genuine gaps in the official toolkit.
How big is the shadow IT problem in 2025?
Studies show the average company now uses over 250 SaaS applications, and IT is aware of fewer than 10-20% of them.
Who is responsible for managing shadow IT?
Ultimately the IT and security teams, but success requires cooperation from department heads and a culture that encourages open communication.
Will banning personal devices stop shadow IT?
No. It usually drives it further underground and damages trust. Governance and better alternatives work much better than bans.
What is a CASB and how does it help?
A Cloud Access Security Broker (CASB) sits between users and cloud services. It discovers shadow IT, enforces policies, and prevents data leaks.
Are free tools always shadow IT?
Not always. If IT has evaluated and approved a free tier (for example, the company allows Miro free boards), then it is not shadow IT.
How can small companies deal with shadow IT?
Even startups can use lightweight tools like Microsoft 365 usage reports, Google Workspace audits, or affordable SaaS management platforms.
Does remote work increase shadow IT?
Yes, dramatically. When people work from home, they naturally mix personal and work tools unless clear boundaries and good corporate options exist.
Can shadow IT lead to GDPR or HIPAA fines?
Yes. If personal data ends up in non-compliant tools, regulators can issue massive fines, even if the breach was accidental.
What should an employee do if they are already using shadow IT?
Talk to IT immediately. Most companies prefer honesty and will help migrate data safely rather than punish the employee.
Is Zoom personal account shadow IT if we have Microsoft Teams?
Yes. Using any unapproved communication platform for business discussions counts as shadow IT.
How often should companies review their approved tool list?
At least twice a year, or whenever a department complains about productivity bottlenecks.
Can automation completely eliminate shadow IT?
No, but modern SaaS management platforms can reduce it by 70-90% by giving visibility and streamlining approvals.
What is the biggest myth about shadow IT?
That it is always malicious or careless. In reality, it is usually well-meaning employees trying to do great work with the best tools they can find.
Will shadow IT disappear in the future?
Unlikely. As long as innovation in cloud tools outpaces corporate purchasing cycles, employees will experiment.
Where should a company start today?
Run a simple discovery scan or send an anonymous survey asking “What apps do you use that IT might not know about?” You will be surprised by the answers, and it opens an honest conversation.
