Corporate Guardian
Inappropriate Internet usage means a lot more than browsing pornography. It is a problem that cannot be ignored, for allowing users unrestricted Internet access can result in serious financial, legal and social consequences. Bad publicity, time wasting, copyright violation as a result of music downloads, the viewing of explicit content and co-worker complaints are all problems that occur unless controls are put in place. Yet many organisations are fearful of the complexity and cost of the content filtering solutions - but SmoothWall has the answer, Corporate Guardian, the most effective, affordable and easy-to-use solution available. Dynamic
Content Analysis is the key technology that makes SmoothWall's Guardian
solutions so much more effective than other filtering products. The Dynamic
Content Analysis filter scans web pages for words and phrases from numerous
categories, including pornography, violence, drugs, racial hatred and gambling.
A sophisticated page weighting system recognises content that is clearly work
related, so avoiding the problem of over blocking medical and technical pages
experienced by other content filters.
Our Dynamic Content Analysis technology works for every web page in existence,
regardless of whether it has ever been seen before or categorised, ensuring
that users are not exposed to unsuitable or illegal content. With more than
half a million new pages being added to the web every day, the traditional
blocklist technique of pre-categorising all web pages is becoming increasingly
unworkable.
Integration
with Microsoft Active Directory user authentication systems avoids the need to
replicate or maintain user IDs and passwords on the Corporate Guardian system.
The membership of Windows security groups is used to determine which filter
rule-set is applied to each user. Thus no routine user management is required
on the Corporate Guardian system; this being performed on the Windows 2000 or
2003 server.
Corporate Guardian includes comprehensive reporting facilities to monitor
Internet usage. Numerous standard reports provide managers with information in
both text and graphical formats on the most visited sites, attempted access to
blocked pages, user activity and bandwidth utilisation. A "Drill down"
mechanism allows any information to be explored to a greater depth, for
example, from a report of blocked sites find which people have been attempting
to access any particular site.
Corporate Guardian keeps objectionable content at bay, reduces time wasting and
avoids legal issues by ensuring that Internet usage is work related.

SmoothGuardian, effective, affordable, easy-to-use and integrated with your
SmoothWall firewall solution.

SmoothGuardian determines the correct filtering policy to apply based on the
user identity or the IP address of the user PC. In conjunction with Advanced
Firewall, user identity is determined by verifying username and password
against a Microsoft Active Directory® or other LDAP authentication system. This
avoids the need to replicate or maintain user IDs and passwords on the
SmoothWall system. Advanced Firewall parses the list of Windows security groups
of which the user is a member in order to determine the filter policy and
rule-set to apply to the user. Thus no routine user management is required on
the Advanced Firewall system; this being performed on the Windows 2000 or 2003
server.
The new malicious code detection features of SmoothGuardian 4.0 detect and
remove common in-page exploits from HTML web pages, such as Active-X controls,
Java Applets and Scripts. Such in-page exploits are not recognised by
traditional anti-virus software, yet are often used to install spyware, viruses
and Trojan horse software on user PCs. Likewise, the new malicious URL
detection features help to prevent users falling victim to phishing scams,
where they are directed to bogus websites by emails containing spoof URLs that
appear to come from banks and other legitimate senders.
SmoothGuardian includes comprehensive reporting facilities to monitor Internet

SmoothGuardian keeps objectionable content at bay, reduces time wasting, avoids
legal issues and is a vital element in anti-virus and anti-spyware precautions.
School Guardian Integrated

with Microsoft Active Directory®/LDAP user authentication. Deep
Packet Inspection techniques are used to detect and block port agile Peer to
Peer network traffic. School Guardian is only available to educational
institutions.
Dynamic Guardian AnalysisDynamic Content Analysis is the technology that makes SmoothWall's Guardian so effective at blocking unwanted or objectionable web content. Most web filters (note we do not call them content filters) rely upon a blocklist of several million pre-categorised web sites and pages. This may sound impressive until one takes into account that Google currently indexes more than nine billion web pages and at least half a million new web pages are created every day. The growth of the web is seemingly exponential - thus keeping pace with a comprehensive blocklist is becoming an ever more difficult, if not an impossible, task. Furthermore it is not foolproof, for if a user accesses the web via an external proxy server it may well be possible to fool
such blocklist systems into believing that all web pages are coming from an
acceptable source. Likewise search engines will display links and page snippets
from offensive or pornographic web sites, sometimes even when the search terms
are totally inoffensive.
The solution is to examine the actual page content, not where it appears to
come from.
SmoothWall's Guardian web content filtering products incorporate a proxy server
that processes all user requests for web pages. As web pages are received, the
Dynamic Content Analysis engine compares the text against categorised word and
phrase lists, looking for objectionable, non work-related and positive
work-related content. Every time a match is made, a weighting value for the
word or phrase is added to a page score. Matching of positive work-related
phrases will offset the presence of words from other categories, to avoid the
false blocking of medical related pages for example. Once the page score
reaches a threshold blocking value then the page will be blocked and a "Blocked
Page" message sent to the user's computer instead of the requested web page.
Guardian does all this at lightning speed; its Dynamic Content Analysis engine
works can examine the entire content of a typical novel in just a fraction of a
second.
User authentication determines the content filtering policy that needs to be
applied, using configurable filter rule-sets for particular user groups. The
blocking threshold for a rule-set would be set appropriate to members of the
group, typically being set very low for young children, a moderate value for
high school children and higher still for most adults. Different word and
phrase categories can be enabled or disabled for each filter rule-set. For
example, the marketing department could be allowed to view news sites but for
other users could be denied access to such pages, or only allowed access at
certain times of day. System administrators can even add their own words,
phrases and weightings into custom category lists to fine tune filtering
behaviour specifically for their organisation.
It is the speed and sophistication of our Dynamic Content Analysis technology
that makes it possible for Guardian to analyse the actual page content. Most
web filters only perform the quick and simplistic action of checking URLs
against a blocklist. Guardian is the "true" web content filter, the most
accurate, the fastest and most flexible solution available.
