eSafe Circumvention Prevention

Unbeatable Protection Against Anonymizers and Security Circumvention Tools

Anonymizers are websites or tools that hide a user's real IP address, therefore allowing them to bypass security measures or policy restrictions enforced on the local network. They have proven to be extremely harmful for businesses, schools and other organizations because they open up security holes and widely expose the network to destructive threats, such as malware.

For organizations and staff members who are dedicated to keeping their network environments secure, anonymizers create additional vulnerabilities, liabilities, policy enforcement issues, and productivity problems that can make an already challenging job even more difficult.

“27% (of respondents) said they would consider using anonymous proxies and 9% are already using them”.

Traditional security solutions such as URL filtering, which rely on signature lists, cannot protect against anonymizers because these sites frequently change URL addresses and outpace most signature lists. eSafe is the only intelligent web security solution that provides true real-time protection from the threats posed by anonymizer technologies, while delivering the line-speed performance you need to ensure transparency and availability.

Going beyond traditional filtering methods, eSafe proactively blocks anonymizers based on their site code and behavior -- even if its encrypted by SSL protocols -- and is the only solution that completely defeats anonymizer technology, protecting the integrity of your network, safeguarding your investment in security and limiting your liability from employee abuse of resources.

Part of a complete eSafe Web Solution, eSafe is able to block 100%* of anonymizers using the following modules:

eSafe Web SSL: Provides transparent inspection of all encrypted (HTTPS, SSL, TLS) web traffic and policy based certificate authorization at the gateway.

eSafe AppliFilter™: Monitors and blocks unauthorized Internet traffic and application protocols, such as P2P, IM, Skype, etc. Protects against application level threats, and provides policy enforcement/control of all inbound and outbound communications, regardless of port.

URL Filtering: The industry's largest, most accurate and most advanced database of restricted Internet sites in 60 categories. It covers 97% of commonly browsed web pages, and is constantly updated. Uses intelligent web crawling technology, content analysis, and high performance hardware to deliver additional filtering enhancements.

*Aladdin's Content Security Response Team (CSRT) blocked 100 percent of anonymizers in repeated lab tests, keeping computers free from viruses, spyware, worms and other malicious threats. Competitive solutions did not stand up to proxy threats and allowed users to leave the protected network.

Triple-Layered Dynamic Enforcement

Until now anonymizers have been difficult to beat. These malicious servers frequently change URL addresses, thereby fooling traditional Web content filtering technologies and outpacing even the largest of signature lists. In addition, new anonymizer technologies can create an encrypted tunnel to the Internet, which bypass corporate perimeter guards that are blind to encrypted traffic.

This means that you have two options: put your invaluable security and protection needs in the hands of employees or students who "might" comply with your Internet usage policy, or get protected with eSafe, the only solution to deliver complete, real-time protection by working across multiple layers to:

• Deliver real-time identification of anonymous proxies by analyzing and correlating their behavior (not just by their URL, IP or port) revealing disguises and blocking tunneling efforts.
• Identify SSL-encrypted anonymous proxy sites, decrypting them for further inspection by the additional layers.
• Provide advanced URL filtering that supports policy and productivity and blocks access to known anonymous proxy sites, and unrecognized sites, whitelists, and blacklists.

Want Proof?

An Aladdin eSafe Web Threat Analyzer (WTA) audit evaluates your organization's existing protection, identifies strengths and weaknesses, and delivers relevant, strategic improvement advice. And best of all, the WTA Audit clearly and objectively reveals if anonymizers are allowing users to circumvent your current security solution. It's the PROOF you need to take smart, efficient, and pro-active steps in the right direction.
