ContentKeeper WebHow it works

A less technical view

  • To provide in simple terms, an overview of how ContentKeeper Web works.
  • This presentation is not intended to provide an exhaustive overview of features of ContentKeeper.

Place an appliance (P/C) in the internet path

All traffic to and from the internet passes through this appliance

  • As each message passes through the appliance….
  • Logs it.
  • Examines it against our URL file and against a policy file.
  • And either allows it to go through or sends the user a block screen,

The URL file (stored in memory) contains an entry for every URL that has ever been accessed by any ContentKeeper user in the world.

URLs are classified according to content.

More about how we maintain the URL file later.



LOG File

  • The policy file contains the predefined access policies for the site (up to 200 policies per client)
    • What classifications of site can be accessed.
    • When they can be accessed.
    • What file types that can be downloaded.
  • If the URL request does not conform to the policy it is blocked.



LOG File

  • The log file contains a record of each web session
  • Information such as
  • User Name
  • URL Accessed
  • Time spent on the session
  • URL classification
  • MB Used

Canberra Support Center

Communicating with the ContentKeeper site

On an hourly basis the appliance will receive new discovered and classified URL’s from the central ContentKeeper site.

The central site will receive any URLs that have been discovered on the clients appliance.

We also use this link to download new software and for support

What happens if a user accesses a URL that we don’t have recorded in the URL file?

how does contentkeeper do it
How Does ContentKeeper Do It?
  • ContentKeeper has a built-in real time engine to catch new sites as well as the industry’s most up-to-date site control list.
  • Any new suspect URLs discovered locally, are encoded, encrypted, compressed, and sent back every hour to the Data Centre.
  • The Data centre automatically analyses the URL using its more comprehensive AI programs.
closed loop collaborative filtering tm technology global collection with hourly updates
Closed-Loop Collaborative FilteringTM Technology(Global Collection with Hourly Updates)
  • All other Contentkeeper sites will have their URL files updated at the next hourly update.
  • In this way all users of ContentKeeper contribute towards keeping the URL list up to date.

Additionally CK Canberra have an automated process that gathers, analyses, categorises and adds previously undiscovered URL’s to the hourly trickle.

for example optional skip to 19
At the Users Site ……

Now if a user in London goes to a brand new site the request packet is inspected by ContentKeeper. Firstly, ContentKeeper checks the URL in the URL file in the appliance and if the URL was found, acts according to the policies in the policy file.

If the URL is not found then the AI engine kicks in and starts analyzing the data stream in real time.

ContentKeeper will allow the first page through so that it does not slow down the network traffic. About 60 seconds later, when our friend is about to click on the next link on that web site, the AI engine has finished its job and that site will be blocked instantly.(If it does not conform to the policy).

Meanwhile the newly discovered URL is stored in the appliance.

And sent to the ContentKeeper data centre at the hourly update.

For example*** Optional – skip to 19 ****

The discovered URLs are passed through all the ContentKeeper AI engines for in-depth analysis.

If they come out of that process still looking like porn for example, then they are added to the Global Control List and collected by every ContentKeeper appliance worldwide during the next hourly update cycle.

Back in London….
  • Our user who may have received one of those SPAM emails, may have been the 1st guy in the world to go to this new site.
  • With the traditional products it’s like a wide open gate, they are powerless to stop them.
  • With ContentKeeper, the site will be blocked locally within 60 seconds and then within an hour or so of discovery, that new site is blocked in Thailand, Europe, UK, USA, Australia and all around the world.
closed loop collaborative filtering
The Key differentiator….

Whereas the traditional filtering companies employ approximately 20 to 40 staff and single point web crawlers looking for new sites, ContentKeeper has several million users discovering new sites, automatically, 24 hours a day, 7 days a week.

Clearly, ContentKeeper’s globally based CLOSED LOOP COLLABORATIVE FILTERING TECHNOLOGY is a far superior methodology for tackling this global problem. Better than any other solution on the market today.

Closed Loop Collaborative filtering
there s more
ContentKeeper’s Quality control is built in!.

Other vendors have no effective Control List review with only approximately 40 staff.

ContentKeeper once again utilizes CLOSED LOOP COLLABORATIVE FILTERING to insure the quality of the database.

Whenever any of the ContentKeeper administrators/users around the globe come across an incorrectly classified URL, they can simply and instantly re-classify that URL fixing the problem on their own site while at the same time automatically contributing to the Quality of the Global List by submitting a reclassification request.

The request is handled by the data centre in the same way.

There’s More …
this means
This means that while the competitor's control list is increasing in a linear fashion, ContentKeeper’s list is growing exponentially.

While their control list quality is increasing in a linear fashion, ContentKeeper’s list is improving exponentially.

Whereas their quality control relies on their own staff (<40), ContentKeeper has several million users, automatically helping to maintain and improve quality, working non-stop around the globe.

  • Install ContentKeeper in client’s site in “Silent Mode”. This takes about 20 minutes.
  • After a period extract logs from Appliance and Produce savings report.
  • The savings report will tell you
    • How your bandwidth is being consumed.
    • What site categories are being accessed.
    • What productivity losses are being incurred.
    • The savings that would be made by enforcing a sensible policy.
