The Websense Approach
In the past, most Web content was static and predictable. But today’s reality is
that Web content—even from so-called “trusted” sites—is constantly changing
with end-users encouraged to post, edit, or manipulate content. The most
popular and heavily-trafficked sites that make the most use of dynamic Web 2.0
content, are also the most vulnerable to attack. In fact, according to Websense®
research covering the first half of 2008, over 60 percent of these top 100
sites either hosted malicious content or contained a masked redirect to an
illegitimate site.*
The Web security landscape is changing: heavily-trafficked sites contain
the most dynamic
content, which bypasses most legacy security systems.
Websense understands both the content and the context of the Internet landscape
through its industry-leading ThreatSeeker Network, and feeds this
intelligence into all its security solutions. Websense is the first security vendor
to address the risks of Web 2.0 by deploying ThreatSeeker analytics inline at
the customer’s gateway, providing dynamic, adaptive protection against new
threats and uncategorized content.
Websense customers can now harness the power of Web 2.0, while keeping
security risks in check by examining the content of both inbound and outbound
HTTP and SSL-encrypted traffic. Real-time content analysis is combined with
powerful anti-malware, Web reputation, and URL filtering protection to proactively
block malicious content before other security solutions even know
it exists. This approach keeps networks secure, while still enabling the latest
Web-based tools, applications, and legitimate content.
Websense ThreatSeeker Network
The Websense ThreatSeeker™
Network adaptive security technology
uses more than 50 million
real-time data collecting systems
that continuously monitor Internet
content—including new and dynamic
content—for emerging threats. The
Websense ThreatSeeker Network
feeds this intelligence into its Web
security, messaging security, and
data loss prevention solutions. As a
result, Websense is able to adapt to
the rapidly changing Internet at
speeds not possible by traditional
security solutions and basic email
filtering solutions.
The ThreatSeeker Network:
- Analyzes more than 40 million
Web sites per hour
- Assigns reputation to more than
2 million domains, networks, IP
addresses, and hosts every hour
- Scans nearly 10 million emails for
unwanted content and malicious
code every hour
- Captures more than 10 million
unsolicited spam, phishing, or
exploit campaigns every day

The Web 2.0 Challenge:
The Internet is rapidly evolving and Web 2.0 technologies are dramatically changing
the way people communicate and work. As the powerful, collaborative nature
of Web 2.0 is creating a new way of doing business, it also introduces
unprecedented security risks. Web 2.0 applications are rapidly appearing on the
desktop, from Web-based mashups to hosted services to user-generated content
and applications.
The dynamic, user-generated content common to Web 2.0 cannot be monitored
with legacy security models, such as reputation databases or URL filtering. This
presents IT security teams with conflicting challenges—how to tap the enormous
potential of Web 2.0 while keeping networks, end-users, and sensitive data secure.
The changing desktop: Web mashups, user-generated content, widegets
and hosted applications
present new security challenges.
Say Yes to Web 2.0
As new capabilities made possible by Web 2.0 enter the business mainstream,
simply denying access and blocking the use of these technologies is no longer
a viable option. To take advantage of the business opportunities of Web 2.0,
organizations need to know that essential corporate information is being protected.
With Websense, IT professionals can provide access to the latest Web-based tools
and applications while still keeping the enterprise safe from attack. With the
unrivaled knowledge of the threat landscape, real-time analysis of dynamic
content, and comprehensive inbound and outbound security found in Websense
Web security solutions, IT professionals can now say Yes to Web 2.0.
Web Security Products:
Websense Web Security Gateway analyzes and secures Web traffic in real-time,
enabling safe use of the latest Web 2.0 sites and tools. The Web Security Gateway
adds on-premise, proxy-based content analysis of Web and SSL traffic to the
robust Websense Web Security and Websense Web Filter platform. This allows
instant categorization of new sites and dynamic content, while proactively
discovering security risks and blocking dangerous malware. The Websense Web
Security Gateway includes:
-
The Active Security module deploys state-of-the-art ThreatSeeker analytics
at the gateway to detect, block, or strip malicious code before it enters the
network. Using advanced heuristics, rules, signatures, and behavior detection,
these analytics are integrated with the global ThreatSeeker Network providing
continuous updates and fine-tuning to detect the latest threats.
-
The Content Gateway module provides inline classification of new content,
along with decryption and scanning of SSL traffic. Built on a robust Web proxy
and caching platform, the Content Gateway module can identify proxy avoidance,
adult, hacking, and many other types of content, protecting users from
the potential risks of new, unknown Web content.
Websense Web Security Gateway combines powerful security with unrivaled
ease-of-use. An intuitive management dashboard provides immediate feedback
on network security, threat detection, traffic loads, and user activity. Combined
Integrated policy management, reporting, and delegated administration saves
time and effort while reducing errors that can lead to security breaches.
