SecureTide™ Hosted Spam Protection

SecureTide™ acts as an organization's gated "front door,” shielding Internet facing SMTP gateways and message servers from numerous threats so that only legitimate e-mail is delivered to user’s inboxes. The SecureTide™ filtering system is continually revised 500-1500 times per day to ensure protection from even the newest Spammer tricks and tactics, including fraud and phishing attacks. At no additional cost, SecureTide™ checks messages for viruses, worms, and other protocol-based vulnerabilities. Anti-virus signatures are updated every 10 minutes.

SecureTide™ is AppRiver's solution for preventing spam, phishing scams, viruses and other internet pollution from impacting our clients operations. While SecureTide™ is best known for its accuracy and low maintenance, equally remarkable is its ease of implementation. The following six steps outline how the SecureTide solution acts on client email to determine whether hand-off to the client email system or the offsite quarantine is more suitable.

At the heart of service is a proprietary Spam detection system that utilizes more than 60 types of filtering techniques. In addition to sophisticated Spam identification analytics, SecureTide™ employs multiple anti-virus engines as well as proprietary detection systems that rid incoming email of worms, viruses, phishing attempts and other protocol-based vulnerabilities.

Step 1. Perimeter Protection

SecureTide™ intercepts messages before they reach the clients infrastructure to prevent high impact attacks such as Denial of Service (DOS) and Directory Harvesting programs from stealing email processing resources.

Step 2. Redundant Server Set

SecureTide™ uses an array of redundant servers to ensure that at least one server will always be available to deliver mail. Each server set is equipped with AppRiver's proprietary Spam detection system that utilizes more than 60 types of filtering techniques. All servers also contain multiple anti-virus engines and proprietary detection systems that rid incoming email of worms, viruses, phishing attempts and other protocol-based vulnerabilities.

Step 3. Virus Scanning

In today's world, viruses are the favorite tool used by spammers to enable the mass delivery of spam. AppRiver uses three anti-virus engines which are updated every 10 minutes to ensure the signature databases are current. AppRiver's own wave-front detection system is used to identify and block unkown viruses providing an extra layer of virus protection. Emails that fail any of the anti-virus tests are routed to the Virus Quarantine for review by the system administrators.

Step 4. SpamTrap™

The AppRiver Spam Filtering system uses the results from a blend of leading spam identification techniques to determine whether a message is legit or belongs in the Spam Quarantine. Some of these tests include internal and external RBL checks, routing analysis, signature and heuristic content inspection and reputation review. Drawing on our worldwide spam traps the system is updated between 500 and 2500 times per day providing consistent spam capture rates of up to 99%.

User Quarantine

Messages that are identified as spam or containing a virus are parked in AppRiver's offsite Spam or Virus Quarantine. The detained emails can be viewed and/or released by administrators or individuals users depending on the configuration selected by the administrator. User-level logins as well as email reports eliminate anxiety over potential false positives and optionally allow tracked message releases.

Step 5. Delivery Manager/Store and Forward Service

Because uninterrupted email service is now a requirement for most businesses, AppRiver's Delivery Manager protects your business from unexpected interruptions - natural, accidental, malicious or otherwise. Delivery Manager components include:

• Store and Forward Buffering
• Load Balancing
• Email Delivery Fail-over Support
• Emergency Mail Service

Each element increases the resiliency and control of email architecture - one of the most visible and sensitive enterprise applications.

Step 6. Delivery to Your Network

Our ultimate goal is to deliver spam-free, virus-free email messages to your network. Our six step process prevents spammers from capturing an innocent email server for their dirty work of relaying spam and viruses, and enables clients to utilize email as the communication tool for which it was created.
