iPrism's exclusive Circumvention Defense Network is an Internet site blocker that stops attempts by circumvention tools to connect to their network proxy or re-routing servers, rendering them harmless and protecting your organization
Employees or students trying to circumvent your network have a number of new tools at their disposal. Most of them are client-side applications that are hard to detect for any Website blocker solution, because new versions are constantly being released, which will change their communication behaviors. If you are wondering
how to block internet sites that host these tools, they work by connecting to a growing number of externally-hosted servers that proxy or re-route the original Web request, evading your Internet site blocker and allowing anonymous browsing and its inherent risks such as exposing corporate networks to malware and data loss. Because these circumvention tools are changing so fast, it's almost impossible for any IT administrator trying to block these internet sites to keep up.
iPrism's new Circumvention Defense Network is a website blocker that stops attempts by circumvention tools to connect to their network proxy or re-routing servers, rendering them harmless and protecting your organization. Once iPrism determines that the circumvention threat has been detected, iPrism's Email Alerts and Real-Time Monitor features can be used to block the internet sites and take more serious action if required. iPrism's historical reporting features can document website blocker activity that regulatory compliance, your acceptable use policy and security policies are being enforced.
EdgeWave Leverages hundreds of frequently-reset virtual machines that are hosted in our scalable cloud data center to detect thousands of externally-hosted non-web servers used by various circumvention sites. To enable our website blocker, we then correlate and filter these IP addresses against those shared with known legitimate websites to eliminate false positives. The results are synchronized with your on-premises iPrism and you get immediate protection to block the internet sites detected. This transparent process enables iPrism to inspect outbound traffic and apply a website blocker, preventing circumvention tools from connecting to their server networks outside. Currently, the iPrism circumvention website blocker feature monitors and blocks UltraSurf, Tor and JAP. However, new circumvention attempts are continuously being detected in the cloud, so your iPrism Website blocker capabilities can stay ahead of emerging threats.
