Email Filtering Technology

MX Logic® Email Defense Service Technology

Advanced technology protects your email network

Spam accounts for over 80 percent of all email worldwide. It is a costly drain on time and resources and continues to threaten network security as it acts as a host for destructive worms and viruses.

The MX Logic Email Defense Service is a fully managed, cloud-based service based on proprietary technology that blocks over 99 percent of spam viruses, worms and harmful content and attachments and eliminates 90 percent of spam-related costs.

Multi-layered, network perimeter protection

MX Logic identifies and controls spam using a patented method found only in our Stacked Classification Framework®. Through a voting algorithm based on a sophisticated form of intelligent reasoning, the Framework successfully combines over 20 separate spam, virus, content, attachment, and email attack filters to protect against the world's latest threats.

Within the Framework, the different spam filters separately assess and vote on the probability that a specific email is spam - a technique that results in highly-accurate threat protection with industry-leading low false positive rates. Then, as new spam-detection techniques and filters are developed, these are quickly and seamlessly integrated into the flexible Framework.

The Framework includes:

• IP Reputation Connection Manager
• Deep Content Analysis^SM
• Premium Anti-Spam Multi-Language Filter
• Statistical Filtering
• Sender Policy Framework(SPF)/Sender ID
• Proprietary Heuristics
• Reputation Analysis
• URL filtering
• Reputation-based RBL filtering
• Domain-level black and white lists
• Distributed black lists
• Recipient deny lists (Address)
• User-level black and white lists

Leading anti-virus engines

The MX Logic Threat Center proactively tracks and blocks the latest waves of worm and virus attacks using sophisticated content behavior analysis, proprietary scanning and triple anti-virus engines. With MX Logic, we automatically strip worms and viruses from incoming email before they can enter your business network.

• Proprietary worm filtering: MX Logic WormTraq worm detection technology identifies and intercepts zero-hour mass-mailing worms before they enter or leave a corporate network.

• Leading signature-based virus scanning engines: MX Logic leverages advanced, signature-based virus scanning from industry leaders to detect, quarantine, block and strip viruses and worms before they can enter and damage your corporate messaging infrastructure. MX Logic scans for anti-virus updates from these services every five minutes.

Fraud Protection

The MX Logic combination of industry-leading spam-fighting methods is also designed to protect organizations from phishing and fraud. Using the same methods to detect spam, phishing emails and fraudulent content are identified and filtered out of inbound email before they reach the network - ensuring that they never reach or dupe employees.

Content and Attachment Filtering

Many organizations want a solution to block the inbound and outbound transmission of private or proprietary corporate data, racially- and sexually-insensitive material, profanity, or anything considered inappropriate. MX Logic® Content and Attachment Filtering supports this type of specific keyword filtering, while protecting the business network from the bandwidth-draining effects of dangerously-sized or malicious attachments. The filtering integrates:

• Keyword filtering
• Attachment filtering
• Archive and compressed file integrity filtering
• Spam beacon and Web bug detection and blocking
• Multi-level HTML Shield and content protection

Email Attack Protection

MX Logic® Email Attack Protection provides real-time monitoring and analysis of incoming messaging traffic, conceals critical messaging gateways and shields groupware email servers from attack. By pointing your MX record to our SecureMX, you can conceal your organization's Internet-facing mail servers and remove the threat of anonymous connections. Malicious traffic is identified and quarantined at the network perimeter to prevent Directory Harvest Attacks and block Denial of Service attacks.

Secure Message Delivery via Transport Layer Security (TLS)

The MX Logic® Email Defense Service supports SMTP over TLS - accepting, filtering and delivering encrypted inbound and outbound messages across a secure tunnel when recipients are TLS-enabled. If a recipient is unable to receive a TLS encrypted tunnel, MX Logic will deliver the message via standard SMTP.

Outbound Message Filtering

While the MX Logic Email Defense Service is protecting the network from malevolent incoming email, the MX Logic® Outbound Message Filtering can protect intellectual property by preventing accidental or intentional distribution of sensitive or proprietary internal information. Our outbound message filtering includes:

• Content Filtering
• Attachment Filtering
• Virus and Worm Scanning
