Had found in news, that Websense had announced, that it intended to acquire SurfControl.
Number of players at the content security market continue to decrease - Who will acquired next?

About information leakage prevention
The Gartner company had published very interesting report about market of content monitoring and filtering/data loss prevention products. Gartner point, that currently this market is small, but it should grow up to $120-150 million in current year.
Currently in this branch (by the version of Gartner), there are 3 leading companies - Websense (after acquiring of PortAuthority), Vontu and Vericept. Many providers of content filtering solutions (Clearswift, Secure Computing, etc.) was excluded from the analysis, as their products doesn't has a required functions - absence of data collection and static analysis, limited capabilities for the filtering of outgoing traffic, no common subsystem for defining and controlling filtering policies.
It's interesting to mention, that many of things, described in this report - collecting and classification of information, linguistic analysis, etc, already was described by me as the things, that will needed for future development of the content filtering systems. I'll continue analysis of data, and will write about the results in this blog.

about notes in blog
I want to mention, that i also has some notes about content filtering in my personal blog. They are marked with Content Filtering label. But i'll try in future may avaialable only in this journal, or provide a copy of the notes

My article about content filtering trends & techniques
Today i had uploaded to site my article (in russian) about content filtering trends & techniques, that was published in October 2006 JetInfo Magazine. Article is available here. I hope, that i make translation of article to English in near future.
I had also uploaded earlier article about web-filtering and our product for it, that also was published at JetInfo, and available from their site.

New Acquisition of Cisco
Yesterday Cisco had reported, that it'll acquire a company Reactivity, that sell a XML-oriented appliances. Interesting thing is that, these solutions could play several roles - xml-data filtering and transformation, provide additional shield for xml-based services, etc.
With this acquisition, Cisco will open for itself a new rapidly grown market of EII- & SOA-oriented products.

New version of WebWasher
Secure Computing had announced a new version of WebWasher product - 6.5. It also released a new version of Sidewinder - 7.0.
Both product included Real-time Reputation Scores, that allow users of both products to filter not only by categories of sites, but also with reputation rank, that is updated in real-time, and allow to detect and propagate knowledge about sites, that has malicious code

stopping the image spam
Tumbleweed had announced yesterday a new technology to fight the spam, that going as an image. They call this technology "Adaptive Image Filtering", and use combination of wavelet transformation with fuzzy matching.
This is looks interesting, but i need to test this technology to say about results

web-filtering in web 2.0 env
Introduction of Web 2.0 technologies - Ajax, etc. is headache for developers of Web-filtering products. Information in such web applications smeared between different connections, and sometimes, we can't analyze data properly.
Now i think about developing a new mechanisms for filtering of this applications (many of them are web-mail, chats, etc., that could lead to information leakage). Currently i hold in head blured image of possible approach, but still doesn't have a clear idea.

information interception
last time, many russian customers (and also customers from other countries) ask us about solutions to intercept internet traffic (web, mail, im, voip). Some of them also want to use this system together with usual phones interception systems.
As i know, in Russia exists some systems, that implement this in some way. But no one do interception of all types of traffic. And we, also trying to play in this game - we has several approaches to this, all based on out MailBoss product, combined with different sniffers and dissectors for various protocols, that produce mail like messages and send them into MailBoss, that do text & datatype detection, and process it with different filtering rules.
But interception of full traffic, has different disadvantages - we need to store anormal amount in information, and we can't use usual relational database to do this. So, currently i thinking about implementing something like data storage, used by web search systems.

Content filtering vendors consolidation?
Looking back to the summer's time, i think that security products vendors are started big consolidation process. What we'll have from this process - improved products, that cover all aspects of content-filtering and security, or not? Or they just to trying increase their market share?
I hope, that they go first way, not second ;-)
But i also hope, that not only market share will main decision for customers, and also will select products by they functionality

WebBoss again
We had started development of a new version of our WebBoss (aka SKVT) software. In this version we'll provide following features:
- conditions on HTTP commands, quota's and much more ;-)
- integration with ISS & NetStar URL databases
- authentification of users by IP & MAC addresses
- storing POST's data in database archive
- replace objects with given data
- new web-based interface with heavy use of Ajax
We has too little time to implement this (until the end of the year), but we'll do this!

content filtering of IM
Alladin had developed a new function for their eSafe product - control of IM file transfer. This is very handy feature for companies, who are using IM for their work
DansGuardian. Code quality in open source projects
Today i had look again to the dansguardian code, and had found, that they still converted upper/lowercase with arifmetics operation - they doesn't use locale information, provided by using standard tolower/toupper functions. This wonder me, as i sent my patcht to fix this about 2 years ago, when i planned to use DG in some of open source projects.
As i know - both DG developers working in SmoothWall, and if they programm CorporateGuardian in style of DansGuardian, i wonder how it works!

ahhh, another acquision
In start of July SonicWall had acquered MailFrontier company with their e-mail security products
continue to read google alerts
found an article, in that says, that content-filtering products must make real-time analysis, and don't use pre-defined URL databases. We always use real-time analysis in our products (first product was offered to customers 6 years ago).
There are many approaches to the real-time analysis. Some of them use statistical approach, some of them use genetic analysis technics. Statistical techniques are simple to implement, but powerfull, while genetic is more precise, but harder to implement.
