  • It is now possible to apply configuration changes directly from Admin UI by reloading or restarting the Web Filtering Proxy service.

0.10

Built on February 15, 2021

  • Added several new components and one system services for Traffic Monitoring module. It is now possible to see the summary information about users and domains being browsed through the proxy at the current moment as well as daily, monthly and yearly traffic monitoring statistics.

0.9 and lower

Built on January 26, 2021

  • It is now possible to use the Active Directory groups as policy members. The administrator now adds a group to web proxy just once and then normally manages the users in the Active Directory. The proxy automatically applies correct policy after authenticating the connecting user and looking up his security groups in the LDAP.
  • Added some default exclusions to ease working with Microsoft, Windows Updates, Office 365, Outlook and Apple iCloud.
  • Added activation schedules to the policies. The administrator now can easily have the lunch, weekend or out-of-work filtering policies automatically activated by schedules.
  • Fixed error with POST requests of zero size.
  • Fixed error with connecting to IP addresses (as opposed to normal connection to domain names).
  • Added three proxy authentication backends - Microsoft Active Directory, local users database and IP address labelling. It is now very easy to support proxy authentication using Negotiate authentication (both Kerberos and NTLM authentication schemes are supported). Just install the application on any Microsoft Windows server joined to the Active Directory and enable authentication from Admin UI with two mouse clicks.
  • After successful authentication policy is switched to the better one matching the name of the authenticated user.
  • Added ability to run secure web proxy (HTTPS proxy).
  • Default listener port is now 8080 (normal conventional proxy) and 8443 (secure web proxy).
  • Updated admin guide.
  • Administrative UI is able to show the table of last N processed requests.
  • Optimizations in HTTPS decryption module.
  • The proxy is now capable of performing basic proxy authentication using list of locally configured users.
  • Improved handling of new policy creation.
  • Small improvements and redesign in Administrative UI.
  • Fixed the installation problems on non-English Windows Servers.
  • Two step selection of policies.
  • Better processing of filtering exclusions.
  • The web filtering proxy core is now able to process policies (by user IP, address range or subnet). These filtering policies can also be configured in Microsoft Management Console.
  • History component writes proxy access logs as JSON entries making it very simple to parse.
  • Added updater component that allows for automatic actualization of definition files for filtering modules.
  • Administrative UI is implemented as MMC management snap-in.
  • Improvements in handling of connections to domain names with several IP addresses. Small fixes
