What are ActiveX controls?

ActiveX controls are Microsoft software components that enable interactive functionality within Windows applications and, historically, Internet Explorer environments.

How do ActiveX controls work?

These controls allow applications and web pages to execute reusable software components within Microsoft environments. Developers historically used them to add features such as multimedia playback, file handling, and interactive forms.

Typically, they work through:

  • Component Object Model (COM) – Microsoft’s framework for reusable software components
  • Browser or application integration – Embedding controls into legacy Internet Explorer environments or Windows applications
  • Script interaction – Allowing web pages or applications to interact with controls through scripts
  • System-level execution – Running with access to local system resources and permissions

As a result, these controls enabled rich functionality in legacy enterprise environments. However, this deep system access also introduced significant security concerns.

Common uses

Organizations historically used these controls for several business and application scenarios:

  • Interactive web applications
  • Enterprise management tools
  • Multimedia and document viewing
  • Legacy internal business applications

For example, some organizations used ActiveX controls to support browser-based management consoles or internal workflows. Consequently, these controls became common in older Windows and Internet Explorer deployments.

Security risks associated with ActiveX controls

Although ActiveX controls improved functionality, they also created major security risks.

Risk  Description 
Arbitrary code execution  Malicious controls may run harmful code 
Excessive permissions  Controls may access sensitive system resources 
Browser-based attacks  Attackers may exploit vulnerable controls through web pages 
Legacy software exposure  Unsupported controls may remain unpatched 

Additionally, attackers historically abused insecure controls to distribute malware or compromise systems. Therefore, many organizations now restrict or disable ActiveX usage in modern environments.

Why ActiveX controls matter today?

These controls are less common in modern web environments because modern web standards and browser security models reduced reliance on legacy plugin technologies. However, some legacy enterprise systems still rely on them.

  • Legacy applications may require ActiveX functionality
  • Older environments may still depend on Internet Explorer compatibility
  • Security teams may need to manage outdated controls carefully
  • Organizations often phase out ActiveX during modernization efforts

As a result, understanding this remains important for managing legacy system risks and compatibility requirements.

How Hexnode supports ActiveX control management context

These controls primarily affect Windows application and browser security. However, endpoint management helps organizations enforce security policies on devices that still rely on legacy technologies.

Hexnode supports this context by enabling administrators to manage Windows device configurations and apply security-related policies across endpoints. Additionally, it provides visibility into device status and configurations, which helps organizations monitor managed Windows environments.

As a result, while Hexnode does not manage these controls directly, it helps support broader endpoint governance and security policy enforcement.

FAQs

Organizations historically used ActiveX controls to add interactive features and reusable components to Windows applications and Internet Explorer web pages.

Some legacy enterprise systems still use ActiveX controls, although modern browsers and applications largely replaced them with newer technologies.

They can execute code with significant system access, which may allow attackers to exploit vulnerable or malicious controls.

Microsoft has reduced reliance on ActiveX in modern platforms, particularly after retiring Internet Explorer 11 in most supported Windows environments. However, Microsoft Edge still offers limited compatibility through IE mode for legacy applications.
