Your employees might pose the greatest cybersecurity risk to your business, and it's not just because they click on phishing emails or reuse passwords. The real issue is that they are using applications your IT team isn't even aware of.
This phenomenon is called Shadow IT, one of the fastest-growing security threats facing businesses today. Employees often download and use unauthorized apps, software, and cloud services with good intentions, but they inadvertently create significant security vulnerabilities.
What Is Shadow IT?
Shadow IT refers to any technology used within a company that has not been approved, reviewed, or secured by the IT department. Examples include:
- Employees using personal Google Drive or Dropbox accounts to store and share work files.
- Teams signing up for unapproved project management tools like Trello, Asana, or Slack without IT oversight.
- Workers installing messaging apps such as WhatsApp or Telegram on company devices to communicate outside official channels.
- Marketing teams using AI content generators or automation tools without verifying their security.
Why Is Shadow IT So Dangerous?
Because IT teams lack visibility and control over these tools, they cannot secure them, exposing businesses to various threats:
- Unsecured Data Sharing: Using personal cloud storage, email, or messaging apps can lead to accidental leaks of sensitive company information, making it easier for cybercriminals to intercept.
- No Security Updates: Approved software receives regular updates to patch vulnerabilities, but unauthorized apps often remain unchecked, leaving systems vulnerable to attacks.
- Compliance Violations: For businesses subject to regulations like HIPAA, GDPR, or PCI-DSS, unapproved apps can cause noncompliance, fines, and legal issues.
- Increased Phishing and Malware Risks: Employees may unknowingly download malicious apps disguised as legitimate but containing malware or ransomware.
- Account Hijacking: Using unauthorized tools without multifactor authentication (MFA) can expose employee credentials and allow hackers to access company systems.
Why Do Employees Use Shadow IT?
Most often, it's not out of malice. For example, the recent "Vapor" app scandal uncovered by IAS Threat Labs revealed over 300 malicious apps on the Google Play Store, downloaded more than 60 million times. These apps disguised themselves as utilities and lifestyle tools but displayed intrusive ads and sometimes phished for credentials and credit card information. They hid their icons and overwhelmed devices with full-screen ads, rendering them nearly unusable. This incident demonstrates how easily unauthorized apps can infiltrate devices and compromise security.
Employees also turn to unauthorized apps because:
- They find company-approved tools frustrating or outdated.
- They want to work faster and more efficiently.
- They are unaware of the security risks involved.
- They believe IT approval takes too long and take shortcuts.
Unfortunately, these shortcuts can lead to costly data breaches.
How To Stop Shadow IT Before It Hurts Your Business
You can't manage what you can't see, so addressing Shadow IT requires a proactive strategy. Here's how to start:
1. Create An Approved Software List
Collaborate with your IT team to develop a list of trusted, secure applications employees are allowed to use. Keep this list updated regularly with new approved tools.
2. Restrict Unauthorized App Downloads
Implement device policies that block employees from installing unapproved software on company devices. Require IT approval before any new tools are used.
3. Educate Employees About The Risks
Make sure employees understand that Shadow IT is not just a shortcut but a serious security risk. Provide regular training on how unauthorized apps can endanger the business.
4. Monitor Network Traffic For Unapproved Apps
Use network monitoring tools to detect unauthorized software usage and identify potential security threats early.
5. Implement Strong Endpoint Security
Deploy endpoint detection and response (EDR) solutions to monitor software use, prevent unauthorized access, and detect suspicious activity in real time.
Don't Let Shadow IT Become A Security Nightmare
The best defense against Shadow IT is to address it proactively before it results in a data breach or compliance failure.
