This release is will be a staged roll-out, initially to customers that have explicitly requested it at A notification will then be sent when your site has been scheduled to receive the update.

Recommendation: It is recommended that all existing HTTPS inspection exclusions be recorded, and then removed as many of these will no longer be necessary. When adding in HTTPS exclusions in 30.1, using Access Policies with a custom Category type of Domain List will typically now be the most effective as it supports subdomains. This does however require the application that is attempting to use the internet supports SNI.

Large Object Cache Enhancement A new option has been added to rate-limit the Large Object Cache download speed. This is still experimental, and will not rate-limit in all situations, however will will to provide a level of control previously unavailable to this specific service.
802.1X Authentication Resolution When responding to packets from an NPS server, a specific response header is required, there was a regression in release 30 that meant this was no longer happening. This has been resolved, and the NPS server should again accept the response packets from the CyberHound Solution.
Internet Auth Enhancement Should there be issues with the internet auth service, more mechanisms have been put in place to identify this, and automatically resolve the issue before users notice.


Item Type Details
Microsoft Lync Archive Enhancement For servers that are very busy or otherwise slow, the connection to the CyberHound could time out during the creation of bundles. The internal timeouts have been increased to minimize the chance of them being hit, and ensure successful delivery.
Email Scanning Enhancement Detect and block another specific form of malformed headers, preventing these entering the network.
BIC Agent Enhancement The BIC Agent will now detect the production release of Windows 10, in preparation for it’s full release 30 build.
1:1 NAT Enhancement Previously a reboot was required on release 30 to apply 1:1 NAT changes, this update removes that need, and allows changes to be applied with the system running.
Email Aliases Resolution An issue was identified where a massive email alias list (typically over 100 recipients) would exceed internal limits, causing delivery to not complete. This has been addressed and the limit on email aliases removed.

Major BIC Agent Update, Device Reboot Required

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.
NGFW Enhancement A new permission level has been introduced to allow for “Test policies and recategorization”. This means users can be given the ability to request a recategorization, without the ability to change policies.
Pipe Plus Enhancement If DNS servers have been configured for a specific link, and force route is now automatically added for each of the DNS servers to push the traffic out that link, removing the need to do this manually.
HTTPS Inspection Enhancement If an upstream SSL certificate changes or is temporarily broken, more rapidly detect this and generate a new local certificate.
Redirection Enhancement For captive portal logins and other redirected pages on HTTPS, use SNI for the certificate generation.
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 In some instances on Mac OS X, the agent is not notified that the system has come back from sleep, causing traffic to be block for extended periods, use a secondary method to detect this, and more quickly recover when coming back from sleep.
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.
BYOD Installer Enhancement A new MSI BYOD certificate installer is now available, this is ideal for sites that wish to distribute the certificate installer via group policy. This same installer can run as either a local machine account or a domain admin account, depending on your AD configuration.
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.
