web filter

Our primary goal is to provide software and services that allow us to protect users from objectionable and harmful web content as well as unwanted and possibly objectionable email (spam).  Our two primary products are a  web filter software (Emerald Web Shield) and a hosted spam filter service (Emerald Spam Shield).

Companies can use our products to combat the productivity losses and bandwidth issues. Companies without a spam filter or web filter find themselves at increase risk from the legal liability caused when employees view objectionable web content at work.

Schools can use our web filter products to protect not only faculty members but most importantly their students from the inadvertent viewing of objectionable websites.

Emerald Web Shield ( web filter software )

We filter objectionable websites for users in the easiest and most cost-effective manner possible.  Our goal is to provide protection to users when browsing the web.  We also understand that most companies and schools do not have the staff or the time to spend figuring out what sites should be blocked in a web filter.  We manage the entire system for you.  In most cases we can provide our web filter service without installing anything on-site. Porn site filtering is a major concern in every school.  We find and filter over 10,000 new porn sites each week.  Porn filtration is a primary goal of our web filter, keep children away from porn sites.

Nothing to install on client computers or maintain

Website domain names must be looked up through a DNS server before a web browser can download the site.  By handling those queries as a DNS server the Emerald Web Shield web filter is able to filter web content in a new and unique manner.  This also means that we are not limited to a specific platform and our web filter service can filter any machine capable of browsing the web including Windows, Macintosh, and Unix machines.

Why would I want to use a web filter?

New sites with objectionable and harmful content are published on a daily basis.  Many of the links to these sites are obscure and rarely indicate the content they contain.  And because of the frequent use of web redirectors you can never count on being in total control of your browser.  We find and filter these porn sites before you can be exposed to them.

The Emerald Web Shield web filter software eliminates the threat of known-malicious websites by preventing your browser from even visiting them.  Our real-time List Management system is actively maintained and updated with new sites as they are discovered (as often as 4 times per hour).  The Emerald Web Shield web filter effortlessly blocks the site from being downloaded to your computer.

Emerald Spam Shield (anti spam filter service)

The Emerald Spam Shield is an anti spam filter service that utilizes a redundant cluster of servers to filter spam out of the corporate email stream and send only desired email on to a company's mail network.

The Emerald Spam Shield takes advantage of a unique and effective real-time website rating system to provide maximum protection against spam.  This rating system facilitates the detection and filtering of spam from previously unknown domains.  Messages that contain known-bad domains catalogued by this system can easily be detected.

The Emerald Spam Shield can also "mailbag" your mail in the event that your mail server is offline.  This is similar to using an offsite backup MX service but with the added benefit of spam filtration.  All of your mail is stored on our network of servers and transmitted when your server is online.  We have servers in datacenters in three different states across the US to ensure that our servers are always available.

You have complete control over 11 different engines to filter your email. For any given engine you can choose to simply edit the subject, forward to a specific mailbox, reject the message, or delete it.
