Mailscreen Email Attack Protection
Today, spammers are writing code and developing complex tools that take advantage of the universal openness of email. Although new attacks can easily bypass typical email filtering mechanisms and capture information about end users, businesses can be protected by incorporating Mailscreen Email Attack Protection.
Email Attack Protection from Mailscreen provides real-time monitoring and analysis of incoming messaging traffic, conceals critical messaging gateways and shields groupware email servers from these SMTP-based attacks. By pointing your Mail Exchange (MX) record to our SecureMX, you can conceal your Internet-facing mail servers and remove the threat of anonymous connections.
With Mailscreen’s unique MX record masking technique, malicious traffic is identified and quarantined at the network perimeter to ensure that your network is protected from directory harvest attacks, denial of service attacks, mail bombs, and channel flooding - attacks that can debilitate even the largest email systems.

A closer look
Like a double-edged sword, email has opened the lines of communications for businesses across the globe, but its openness and accessibility has also made businesses vulnerable to a new breed of threats.
Concealing the email network
Directory harvest attacks, denial of service attacks, mail bombs, and channel flooding are sophisticated email intrusion techniques that spammers use to capture information about end users. Because these tools can easily bypass the typical email filter to create chaos and network damage, Email Attack Protection from Mailscreen provides real-time monitoring and analysis of incoming messaging traffic, conceals critical messaging gateways and shields groupware email servers from attack.
A simple redirection of your MX record
By pointing your mail exchange (MX) record to our SecureMX, our unique MX record masking technique conceals your Internet-facing mail servers and removes the threat of anonymous connections. With Mailscreen, malicious traffic is identified and quarantined at the network perimeter to ensure that the network is protected from attacks that can debilitate even the largest email systems.
Prevent Directory Harvest Attacks
Mailscreen Email Attack Protection can defend your business network against directory harvest attacks (DHAs), which methodically bombard email servers with messages by using common name pairs or email address patterns, or uses "brute force" to run through alphanumeric combinations to identify valid addresses. Our solution blocks DHAs at the network perimeter to prevent spammers from gaining information about the validity of random email addresses used to target businesses for future attacks.
Blocking Denial of Service attacks
Denial of service (DoS) attacks are particularly stealthy because while they are designed to elude detection by masquerading as legitimate transactions, the intent is to launch them on a massive scale to overwhelm unprotected networks. When Mailscreen detects the excessive SMTP "chatter" associated with DoS attacks, it limits the connections it will allow from the attacking IP address, throttling back the traffic and effectively stopping the attack.
