03/16 March 16 - Windows Roaming Client v3.3.0 Production

Windows Roaming Client

v3.3.0

is now available in the Production channel. This release brings together several improvements introduced during the 3.x Beta cycle, focusing on

modern DNS filtering with DNS PreCheck

and

expanded endpoint visibility with CyberSight

, alongside major architectural and stability upgrades.

✨ What’s New

DNS PreCheck – Modern Device-Level DNS Protection

DNS PreCheck introduces a transparent DNS proxy that evaluates DNS requests locally on the device before they leave the network stack. This modern filtering approach improves reliability on restrictive or unmanaged networks while reducing conflicts with local DNS settings.

Administrators can configure behavior directly from the dashboard using the

Connection & Filtering Mode framework

, including:

Connection Mode
– Transparent Proxy or DNS Loopback
Filtering Mode
– DNS PreCheck or Classic DNS filtering
Failover Mode
– Fail Open or Fail Closed

This flexibility allows organizations to balance connectivity and enforcement based on their environment.

CyberSight Activity Visibility

CyberSight provides

device-level activity insight

that complements DNS filtering data. It records time-stamped activity to help administrators understand what occurred around security events or DNS blocks.

CyberSight delivers a unified timeline that combines:

Full browser URL visibility
Application activity
Device state changes

This additional context helps teams investigate alerts, detect unusual behavior earlier, and troubleshoot operational issues more effectively.

🛠 Platform Improvements

This release also introduces significant improvements to the Windows Roaming Client platform:

Modernized client architecture
built on updated Windows frameworks for improved reliability and maintainability
Improved configuration management
, logging, and diagnostics to simplify deployment and troubleshooting
Reduced installer size and improved runtime efficiency
for faster deployments
Improved OS compatibility detection
, automatically disabling unsupported networking features while maintaining protection through Classic DNS filtering

🪲 Stability & Reliability Enhancements

Throughout the Beta cycle, numerous improvements were made to strengthen reliability across diverse environments, including:

Improved handling of network transitions, sleep/wake states, and startup conditions
Enhanced DNS failover and IPv6 compatibility behavior
More reliable VPN compatibility detection and filtering behavior
Increased stability in networking libraries and service communication

Together, these updates deliver a more resilient client designed to support modern Windows environments while providing deeper visibility and stronger DNS protection.
