Anti-Spam and Email Archiving to be Retired
Posted by Jim Giseburt on 21 October 2016 11:34 AM

The Anti-Spam and Email Archiving features have long been a part of Cipafilter.  Years ago, Anti-Spam was our number two selling feature behind our superior, proprietary, context-sensitive Content Filtering.

With the advent of Google Apps for Education, now known as G Suite for Education, many of our valued Anti-Spam customers moved to Google for email services which include free anti-spam protection.  Initially, many of those same customers continued to use Cipafilter Email Archiving, because Google charged education customers for their email archiving solution, Google Vault.  In January 2015, Google began to provide Google Vault to G Suite for Education customers for free.

The number of Cipafilter customers that use our Anti-Spam and Email Archiving features has continued to decline.  As a result, it is with a very heavy heart that we announce the retirement of our Anti-Spam and Email Archiving features.

In our soon to be released Version 9.2 firmware, these features will remain fully functional, but will be moved to a Deprecated Features menu.  Effective with the release of our Version 9.6 firmware scheduled for release in December 2017, these features will be completely removed from firmware.  Support for both features will terminate at that time.

We want to thank our customers for their belief in us and our product.  As we retire Anti-Spam and Email Archiving, we will redeploy our Anti-Spam and Email Archiving development team members to our Firewall, Content Filter and Internet Reporting development teams.

We recently introduced our new Advanced Bandwidth Control, web reporting enhancements including:  the InSite report, a Report Card and exclusion filters,...

VPN compatibility with iOS 10 and macOS Sierra
Posted by David Cross on 20 September 2016 07:02 PM

Today marks the release of Apple's latest desktop operating system, macOS Sierra. Sierra joins iOS 10, released last week, in removing support for the PPTP VPN protocol, as announced by Apple Support.

Cipafilter firmware versions 9.1.0 and earlier do not support any alternative protocols suitable for end-user VPN access. As such, Cipafilter's VPN functionality is currently NOT compatible with iOS 10 and macOS Sierra.

A forthcoming release of the Cipafilter 9.1 beta firmware will introduce support for L2TP over IPsec, which is suitable for use with all major operating systems, including iOS 10, macOS Sierra, and even Chrome OS. We do not currently have a release date for this feature, but our developers are working hard to get it out as soon as possible.

In the meantime, customers who rely on PPTP VPN are advised to make alternative arrangements or simply delay upgrading their Apple devices.

If you would like to learn more about becoming a beta customer, please let us know by reaching out to

Important Changes to Google SafeSearch
Posted by Dan Schuler on 03 June 2015 02:59 PM

Google has announced that it will be making some changes to its SafeSearch feature. Currently, when the “Safe Search Enforcement” box is checked on your Cipafilter, searches are sent to a non-SSL version of Google. This allows your Cipafilter to log search terms, as well as to enforce SafeSearch and perform additional filtering through our Enhanced Safe Search features. Due to abuse by external parties, Google will no longer be supporting non-SSL searches and will soon allow only SSL connections.

What this means for you:

Recent versions of Cipafilter firmware will still be able to enforce Google SafeSearch. However, unless SSL Decryption is enabled, Google’s changes will prevent your Cipafilter from either logging searches or using our Enhanced Safe Search features.

Firmware versions supporting this change:

  • 8.6.3 and newer
  • 8.4.7 and newer


If your Cipafilter is on firmware older than the versions listed above, or if you have any additional questions about Google SafeSearch, please contact the Technical Support team at

Posted by Chris Cooper on 28 January 2015 05:10 PM

Qualys recently announced the discovery of a bug (CVE-2015-0235) in the gethostbyname function of the Linux glibc library. This bug is commonly referred to as GHOST. More information on the vulnerability itself can be found on the Qualys Blog


Affected Cipafilter Versions

The following versions of CIPAFilter are affected:

  • 8.6 Release Candidate: 8.6.3 and below
  • 8.4: 8.4.6 and below
  • 8.2: 8.2.56 and below
  • 8.0 and older: All versions affected



The Cipafilter Proactive Maintenance team has been busy hot patching all affected units that can be reached. While we are attempting to reach as many units as possible, it is still recommended to upgrade your firmware to the latest version to ensure the patch is installed. 8.2 and above users may upgrade themselves by visiting the Firmware Updates page on their filter. 8.0 and older users will want to contact support to schedule an upgrade.


If you have any additional questions regarding how GHOST affects your Cipafilter, please feel free to Submit a Ticket.
