Agent v4.5.X-4.X.X (2025)

Windows Agent Release Notes for versions 4.5.X

Added diagnostic logging for the Browser Extension at:
C:\Program Files\Zorus Inc\Archon Agent\Zorus Deployment Agent\logs
Introduced agent support for separate configuration options for Full URL Filtering and IP-Based Browser Filtering, allowing more granular control

Fixed an issue where the Browser Extension installation/uninstallation checkbox failed due to a race condition. The process now runs through the service instead of the session manager
Fixed an issue where the Agent caused the Windows Server DNS service to become unresponsive within a minute of restarting

Added a new parameter to ZorusDeploymentScript to support enhanced installer configuration
Reduced application size by minimizing dependencies on shared components, resulting in a smaller installer
Optimized error logging to improve internal monitoring of server uptime, downtime, and filtering

Fixed an issue where policy lookups would fail due to variable connection timing
Fixed an issue where offline devices were not updating Full URL Feature Enable/Disable status
Fixed an issue where upstream certification verification could fail due to a missing required value (System.ArgumentNullException)

Required Infrastructure for Full URL and IP Browser Filtering: Upgrade to the latest infrastructure with our Zorus CyberSight™ Browser Extension to enhance inspection capabilities and strengthen your security posture through advanced Full URL and IP Filtering
- Prevent Harmful Links: Identify and block malicious URLs, including those concealed within trusted domains
- Mitigate IP-Based Attacks: Shield against threats that evade DNS by targeting direct IP traffic
- Instantaneous Threat Prevention: Analyze and block URLs, IPs, and downloads before they can execute or jeopardize your system

Enhanced Registry Key Monitoring for Agent Health and Configuration: Seamlessly track the health and configuration of agents with our newly implemented registry key monitoring features
- The supported keys include: AgentHealthState, AssignedCustomer, ErrorDetails, isCyberSightEnabled, isFilteringEnabled, IsUpdateAvailable, LastSeen, LastUpdateAttempt, and LicenseId

Enhanced the uninstallation process to completely remove all Zorus associated registry keys upon agent uninstallation
Included the "Malicious Domain List" and "Malicious URL List" in the Category field of the Block Page for easier review when examining blocked content locally
Decreased the frequency of connection attempts to the Policy Server in the absence of network access, thereby reducing unnecessary TCP error logs
Streamlined the connection process for agents to the Policy Server, leading to fewer connection errors

Fixed an issue that caused the service to intermittently fail to start following a reboot on Windows Server 2016
Fixed an issue where the agent service blocked device DNS registration when processing Non-Query DNS Requests, unless the target destination (such as an Active Directory Server or its domain) was included in the whitelist
