03/24 March 24 – Windows Roaming Client v3.3.3 Production

We've released Windows Roaming Client v3.3.3
 to address a DNS restoration issue affecting machines with multiple static DNS servers configured.
🪲 Hotfix
DNS Server Restoration on Multi-Server Static Configurations
 – Fixed an issue where only the primary DNS server was restored when the agent service stopped on machines with multiple static DNS servers. Secondary DNS servers were silently dropped, leaving affected machines with an incomplete DNS configuration.
All configured DNS servers are now correctly restored when the agent stops or restarts.

03/23 March 23 – Windows Roaming Client v3.3.2 Production

We've released Windows Roaming Client v3.3.2
 to address a critical network connectivity issue affecting machines with static IP/DNS configurations.
🪲 Hotfix
DNS Settings Restoration on Static IP/DNS Configurations
 – Fixed an issue where the agent incorrectly overwrote static IP/DNS configurations on restart, causing complete loss of network connectivity with no remote remediation path.
The agent now correctly restores DNS from a saved backup on restart and leaves interfaces untouched when no valid backup exists, restoring 2.x behavior.

Windows Roaming Client

RC Release Channels

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.

RC Release Channels

03/09 March 9 - Windows Roaming Client v3.3.0 Beta

The latest Windows Roaming Client (v3.3.0)
 is now available in the Beta Channel
 and can be downloaded from Deployments → Roaming Clients → Install Roaming Client
 in your dashboard.
✨ What’s New
🧩 ARM64 Support for Windows Devices
The Windows Roaming Client 3.x series now supports ARM64-based Windows devices
.
A dedicated ARM64 installer
 is available in the Beta Channel alongside the standard x64 installer, enabling organizations to deploy the latest client architecture on modern ARM-powered hardware.
🛠 Improved OS Compatibility Handling
The client now validates the Windows operating system version at runtime to ensure advanced networking features run only on supported platforms.
If an unsupported OS version is detected:
Transparent Proxy / DNS PreCheck
 features are automatically disabled
The client safely falls back to Classic DNS filtering (loopback mode)
 so devices remain protected
See our knowledge base for Supported OS and End of Life details
🪲 Stability Improvements
Networking Library Updates
 – Updated underlying networking libraries improve reliability and maintain compatibility across supported Windows environments.

3/3 March 3 – CyberSight Beta for Windows Roaming Client (v3.2.0)

CyberSight is now available in the

Windows 3.2.0 Beta Roaming Client

for customers using the Beta Channel.

To enable CyberSight, go to

Roaming Clients → Control Center → CyberSight

in your dashboard and toggle on CyberSight Analytics and Browser Extension URL.

✨

What’s New

CyberSight Activity Overview & Logs Dashboards

– A new device activity logging capability that records time-stamped user behavior to provide context around security events and operational issues.

CyberSight delivers a behavioral timeline that combines:

Full browser URL visibility
Application usage
Device state changes

All within a single, unified dashboard view.

This creates a clearer picture of what occurred before, during, and after an event — giving administrators actionable context beyond DNS data alone.

✅

Why It Matters

Reconstruct activity surrounding endpoint alerts and suspicious events
Detect unusual or risky activity earlier
Support compliance and acceptable-use reviews with objective activity records
Improve troubleshooting during outages or service interruptions
Maintain visibility even when alternate DNS resolvers or proxies are used

🛠️Improvements

Reduced Installer Size & Improved Windows Agent Performance
– The Windows Roaming Client installer has been optimized to reduce size and improve runtime efficiency, enabling faster deployments and smoother performance across devices.

🪲 Bug Fixes

Improved Configuration Handling During Sleep & Resume
– Resolved an issue where configuration changes processed while a device was in modern standby could result in broken filtering or DNS behavior upon wake. The agent now defers network-impacting changes until the device is fully awake.
Corrected DualStack IPv6 Failover Logic
– Fixed a condition where loss of IPv6 connectivity could leave devices without DNS resolution instead of automatically failing over to IPv4.
Resolved Whitelabel Configuration Issue
– Ensured required configuration files are written during installation for whitelabeled deployments, preventing service startup failures and restoring full functionality for integrations such as CyberSight and dashboard reporting.
Addressed DNS Failures on Startup
– Eliminated a startup condition that caused DNS queries to fail for several seconds before upstream connectivity was established.

RC Release Channels

1/21 January 21 DNS PreCheck Beta for Windows Roaming Client

DNS PreCheck

is now generally available in the

Windows 3.1.0 Beta Roaming Client

for customers using the Beta Channel.

To enable DNS PreCheck, go to

Roaming Clients → Control Center → Connection & Filtering

in your dashboard.

✨ What’s New

Connection Mode:
Transparent Proxy or DNS Loopback
Filtering Mode:
Classic DNS or DNS PreCheck
Failover Mode:

Devices running 3.0 must manually install version 3.1.0.
Duplicate dashboard entries may appear after upgrading to 3.1.0
on devices that were fresh-installed on Windows Roaming Client 3.0 and may require cleanup.
