For large organisations, maintaining security while enabling remote work is a significant challenge. With TeamViewer Hybrid Conditional Access, your organization no longer must choose between control and connectivity. This hybrid solution gives you full sovereignty over session data by deploying routers on-premises, while still benefiting from seamless global remote access.

This article applies to TeamViewer Tensor customers who purchased the Conditional Access add-on.

How Hybrid Conditional Access elevates your security

Hybrid Conditional Access is specifically designed for sectors with stringent data protection regulations, like healthcare, government, finance, and research. It empowers your organization to:

  • Ensure data sovereignty by keeping all session data on-premises
  • Enable secure global access without exposing sensitive information to external risks
  • Maintain compliance with legal and industry-specific security requirements
  • Customize security controls to suit your infrastructure and policies

This provides enhanced control and assurance when supporting remote work, third-party access, and multi-site operations, without compromising on data governance.

How Conditional Access Hybrid works

Conditional Access Hybrid combines cloud-based connectivity with on-premises control. Here’s how it works:

  1. Initial connection setup is made via the TeamViewer cloud.
  2. All sensitive session data, however, remains within your organization's network, thanks to on-site routers (CAHRs).
  3. You manage access rights, availability, and session parameters internally using industry-standard containers.
  4. The system integrates smoothly with your existing IT infrastructure for full visibility and control.
