Your workforce could represent the most significant cybersecurity threat to your organization — and it's not just due to clicking on phishing links or reusing passwords. The real issue lies in employees utilizing applications unknown to your IT department.
This phenomenon, known as Shadow IT, is rapidly becoming one of the top security challenges businesses face today. Employees often install and use unauthorized apps, software, and cloud services—usually with good intentions—but inadvertently expose your company to serious security vulnerabilities.
Understanding Shadow IT
Shadow IT encompasses any technology deployed within an organization without formal approval, vetting, or security oversight from the IT team. Examples include:
●
Employees using personal Google Drive or Dropbox accounts to store and share work-related files.
●
Teams adopting unapproved project management platforms like Trello, Asana, or Slack without IT involvement.
●
Employees installing messaging apps such as WhatsApp or Telegram on company devices to communicate outside official channels.
●
Marketing teams leveraging AI content generators or automation tools without confirming their security compliance.
The Risks of Shadow IT
Since IT departments lack visibility and control over these unsanctioned tools, they are unable to secure them effectively, leaving your business vulnerable to numerous threats.
●
Data Exposure - When employees use personal cloud storage, email, or messaging apps, sensitive company information can be accidentally exposed, making it easier for cybercriminals to intercept.
●
Lack of Security Updates - Unlike approved software, unauthorized apps often go unpatched, leaving systems vulnerable to exploitation.
●
Compliance Risks - Using unapproved applications can cause violations of regulations such as HIPAA, GDPR, or PCI-DSS, potentially resulting in fines and legal penalties.
●
Elevated Phishing and Malware Threats - Employees may inadvertently install malicious apps disguised as legitimate ones, which can contain malware or ransomware.
●
Account Compromise - Unauthorized tools without multifactor authentication (MFA) can expose login credentials, allowing hackers to breach company systems.
Why Employees Turn to Shadow IT
Usually, this behavior isn't malicious. For instance, consider the "Vapor" app incident, a widespread ad fraud scheme uncovered by IAS Threat Labs.
In March, over 300 harmful apps were found on the Google Play Store, collectively downloaded more than 60 million times. These apps masqueraded as utilities and lifestyle tools but were designed to display intrusive ads and, in some cases, steal user credentials and payment information. They concealed their icons and overwhelmed devices with full-screen ads, severely disrupting usability. This case underscores how easily unauthorized apps can infiltrate devices and jeopardize security.
Other reasons why employees might use unauthorized apps include:
●
They find company-approved software outdated or cumbersome.
●
They seek to boost productivity and streamline workflows.
●
They are unaware of the security dangers involved.
●
They perceive IT approval processes as too slow and opt for shortcuts.
Unfortunately, these shortcuts can lead to costly data breaches and security incidents that jeopardize your entire business.
How to Prevent Shadow IT from Impacting Your Business
You can't manage what you don't see, so combating Shadow IT demands a strategic and proactive approach. Here's how to begin:
1. Develop an Authorized Software Catalogue
Collaborate with IT to compile a list of vetted, secure applications that employees are permitted to use. Keep this list current with newly approved tools.
2. Block Unauthorized App Installations
Implement device policies that restrict employees from downloading non-approved software on company devices. Require IT approval for any new tools.
3. Educate Your Team on Security Risks
Ensure employees understand that Shadow IT isn't a harmless shortcut but a serious security threat. Conduct regular training sessions to highlight the dangers.
4. Monitor Network Activity for Unauthorized Applications
Use network monitoring solutions to detect unsanctioned software usage and identify potential security risks before they escalate.
5. Deploy Robust Endpoint Security
Utilize endpoint detection and response (EDR) tools to track software behavior, block unauthorized access, and identify suspicious activity in real time.
