Our Global E-Mail Gateway Service acts as a shield for our customer's e-mail messaging infrastructure. We enhance a company's network architecture extending the capacities and useful life of the security investments already made as well as ensuring greater functionality and user productivity.

Our network is enabled through our fully redundant and geographically dispersed network of servers. This distributed architecture ensures each and every customer a highly reliable and seamless means of layering our gateway protection on top of their present e-mail infrastructure without a moment's disruption to users.

The architecture itself acts as the first layer of protection for customers. The distributed nature of the design automatically protects customers from network-based hazards such as mail bombs as well as Denial of Service (DoS) attacks.

Benefits:

• Highly distributed and geographically disperse network
• Multiple Tier 1 bandwidth providers with extensive peering relationships
• 100% historic uptime with 99.999% service availability guarantee
• Protection against DoS and Mail Bomb attacks

Spam Filter

The Spam filter automatically eliminates "junk" e-mail or "Spam" from each user’s mailbox, protecting workers from unwanted distractions and interruptions. With the ever-increasing amount of unsolicited e-mail arriving daily, protection is an important means of saving time and staying focused on important work at hand.

As e-mail passes through the mail routers, Singlefin’s proprietary Spam filter automatically scans inbound e-mail and separates out any Spam found.

The Spam filter is a system that Singlefin has developed in house. Spam is filtered in a multi-step process. The first step is a collection of millions of “bait” e-mail addresses. These e-mail addresses are used to actively look for Spam. Spam is captured and run through a process in which a fingerprint is created and added to a master database for each message. Next, as each new customer e-mail message enters the Singlefin network, it is fingerprinted and cross-reference in the database to see if there is a match. If there is a match, the message is marked as Spam. If there is no match, the message proceeds to the next step in which it is run through a series of tests where different aspects of the message including the header, subject, and content of the message are analyzed. These tests give the message a score that in turn determines if the message is Spam. Spam messages are fingerprinted and added to the database. Clean messages are queued for delivery to the client. This process, on average, takes less than a second to perform.

Administrators have many options in regards to the filtered Spam:

• SpamTank: With the most popular option being the SpamTank, Spam is held in a user level quarantine on the Global Gateway or the Local Messaging Router. As Spam is identified, temporary junk e-mail boxes are created for each user. Users are notified that they have junk e-mail on the server and are given a link to a web-based control panel where they can check it. The administrator sets the notification interval. Spam is held in this user level quarantine for 30 days before it is deleted.
• Redirection: This option allows administrators to redirect all Spam to a single e-mail address. For example, Spam@yourcompany.com.
• X-Header: This option allows administrators to insert an x-header. Rules can be written on the destination mail server to reroute mail via the x-header variable.
• Subject Line Modification: This option allows administrators to modify the subject line of Spam messages. For example, the word JUNK or SPAM could be inserted before the subject so that the individual users could easily identify Spam messages.
• Deletion: This option quarantines and deletes all Spam messages.

Benefits:

• Proprietary filtering process catches 98% of Spam
• .00001% false positive rate
• Automatic filtering with no maintenance headaches
• Reduces the time-distraction of clearing out unwanted e-mail
• Far less expensive than maintaining own onsite spam filtering system
• Implementation in minutes with a simple change in DNS configuration
• Reduced load on IT staff and mail servers

Virus Filter

The Virus Filter detects and eliminates viruses before they enter your network. The system utilizes two leading enterprise-class virus scanners on the market: Trend Micro and Sophos. Integrated at the application level, the network receives virus definition updates every 10 minutes. All e-mail as well as attachments are scanned through both engines insuring the most complete protection possible. Each of the anti-virus partners maintains global research and solution centers to ensure viruses are identified as early as possible and solutions are implemented as quickly as possible. Being that e-mail management is Singlefin's core business; the anti-virus libraries are updated far more frequently and more efficiently than is possible within a typical company.

• No maintenance windows or downtime, causing the reduction in
  corporate protection
• Implementation in minutes with a simple change in DNS configuration
• Greater e-mail network security with seamless layers of anti-virus protection
• Stops viruses at the gateway level before they enter the company network,
  eliminating the possibility of accidental outbreaks
• Significantly less expensive than maintaining an in-house virus solution
• No staff training required
• Reduced load on IT staff and mail servers
• Easier to implement than any other anti-virus alternative
•  Immediate updates to protect against fast moving virus outbreaks

Attachment Filter

The attachment filter is positioned to reject messages with certain types of file attachments before they enter your current messaging infrastructure. This feature insures potentially destructive files, such as “.vbs”, “.scr”, “.exe”, etc. do not gain access to the customer's network.

Administrators can add or delete file types as well as file names in order to fine-tune the filter. Messages with blocked attachments are sent to the quarantine for administrative review.

• Dangerous files can be restricted and quarantined, making the work place safer
• Preventative layer of protection that is far less expensive than maintaining your own onsite filter system
• Filtered messages delivered to quarantine for review
• Reduced load on IT staff and e-mail servers
• No staff training required
• Easier to implement than any other alternative
• Potential bandwidth savings

Content Filter

The content filter gives administrators the ability to block messages based on words or phrases found in the message subject, message body as well as any attachments. Messages can also be filtered based on character sets (i.e. language types). Any filtered messages are delivered to quarantine for administrative review.

• Ability to maintain full control of e-mail
• Far less expensive than maintaining own content filtering system
• Reduced load on IT staff and mail servers
• Filtered messages delivered to quarantine for review

Policy Filter

The policy filter allows administrators to block messages based on message size as well as number of recipients.
Messages with policy violations are sent to quarantine for administrative review.

• Filtered messages delivered to quarantine for review
• Ability to maintain full control of e-mail
• Reduced load on IT staff and mail servers
• Implementation in minutes with a simple change in DNS configuration
• No user training required

Black / White Listing

The black and white lists give customers the ability to block or allow e-mail messages based on domain name, e-mail sender and e-mail recipient.
