New Features and Enhancements
Item Details
RoamSafe for iOS RoamSafe for iOS is an “Always on VPN” solution for iOS 9 (and above) devices in supervised mode. This solution integrates with most MDM solutions and Apple DEP and provides support for web filtering, application control, firewalling and ClearView social media management. Please refer to the CyberHound appliance Help function for details of RoamSafe VPN configuration.
Internet Quota Permissions for Internet Authentication and Internet Quota configuration are now separate and provide better control of which groups are allowed to access these features.
Firewall Added an option Configuration > Advanced > Allow Asymmetric Routing. On most sites, this should be set to “no” in order to ensure that packets with LAN source addresses are properly blocked from being sent out the internet interface, but it will be set to “yes” on existing sites to avoid blocking legitimate traffic on sites which require asymmetric routes.
YouTube Restricted Mode Added support for forcing YouTube Restricted Mode using DNS instead of cookies. This method is harder to circumvent but cannot be used with group exclusions.
Web Filtering Incorporated real time updates of URL categorization.
YouTube Cache Improved playback of embedded YouTube videos in Safari on iOS.
Web proxy Improved the handling of custom certificates for HTTPS inspection.
ClearView Improved handling of Twitter direct messages.

Item Type Details
Authentication Enhancement Better manage a subset of users on a massive AD servers (i.e.: more than 10,000 users), by providing a filter for desired users for a specific location by security group. Desired groups for a site can be set under Configuration > Authentication in the AD plugin, there is a new field titled “Active Groups”, which is an optional group filter applied to all lookups.
Web Proxy Enhancement The logging for the web proxy has been enhanced to include a lot more data on each request, including categories, user agent, and matching policy for allow rules. A new detailed log option is available for the Web Proxy logs to access all of this information.
Note: If using automated log parsing tools, these will need to be updated to support this new format.
NGFW Enhancement Decide if HTTPS inspection should be done on a specific request based on the SNI header only (not the IP address) this provides more accurate and faster categorization for “Bypass HTTPS Inspection” policies.
NGFW Enhancement Allow the use of custom domain categories for “Bypass HTTPS Inspection”. This includes the matching of subdomains (e.g.: to match and all subdomains). This is now the preferred method for HTTPS exclusions, and some of these will be automatically migrated from the configuration screen.
NGFW Enhancement On the Block Activity report, introduce a new protocol column to match what is available in Network Monitoring.
NGFW Enhancement Block the use of the non-standard QUIC protocol by default for all traffic, enforcing the use of standards based web traffic. This option can be set under Access Policies > General.

BIC Agent Enhancement Enhanced memory management for big local uploads, minimizing the use of local memory.
BIC Agent Enhancement Better handle the corruption of settings on the agent side, and use a different format to prevent leakage of corruption of settings should this occur.

BIC Agent Enhancement Use the newer SHA256 when generating HTTPS inspection certificates.
BIC Agent Enhancement If a reboot is required on the agent, more regularly notify the user that a reboot is required to encourage this to happen sooner.
BIC Agent Resolution When testing policies for the BIC agent under Access Policies, more closely match what would happen on the BIC Agent to provide an accurate representation of the policies that would be applied.
Reporting Resolution When displaying user generated content in a report, if the content is HTML, correctly escape it to prevent display issues.

Archive Emails Enhancement For archive emails and Symantec EV integration, provide more detailed logs on both success and failure.
Direct Proxy Enhancement Provide the ability to exclude local networks and IP’s from authentication on the direct proxy (in addition to remote servers).
Direct Proxy Enhancement If using automatic proxy configuration, a new field is now available to create a custom proxy.pac file, at the bottom of the Configuration > Web Proxy screen. If this is set, the automatic proxy.pac file is not generated, and the custom one is use instead.
Web Mail Resolution In some views, the ordering by date was not working correctly, this has been addressed.

30 / 30.0.1

This release is a rebuild of the CyberHound Solution core OS to the latest generation enterprise platform. This includes everything from the kernel to the userspace environment.

Item Type Details
CyberHound OS Enhancement A complete rebuild of the core OS, from the base kernel upwards. Providing improved boot times (now 3 times faster), more rapid service restart (50%-95% faster), and support for the latest network technologies.
Web Proxy Enhancement Support for SNI (Server Name Identification) for outbound HTTPS requests. This will provide compatibility for those clients and servers utilizing these extensions.
HTTPS Inspection Enhancement Using the SNI header, the ability to exclude hosts from HTTPS inspection is now possible using wildcards, providing the ability to exclude an entire domain, and all its subdomains in a single rule. This requires the clients to be using SNI to get this benefit.
POP3 Server Enhancement The POP3 server now supports multiple simultaneous logins. Although technically a violation of the RFC, the implementation provides each client with a point in time view, that is then merged at the end of the transaction. This allows for the use of multiple devices that keep the connection open without interference.
DNS Server Change The DNS server will no longer automatically provide forward and reverse DNS lookups for local IPs. For example the reverse of a LAN IP of would yield ip-1-1-1-1.lan, and there would be a forward lookup for the same.
