We provide protection for your EMail Filtering Services from outside attacks. Our extensive attack protection includes protocol anomaly detection, application and protocol state tracking, Network Address Translation, as well as other technologies. We all use attack detection and mitigation techniques involving application/ protocol command filtering, content verification, and URL debofuscation.
We also utilize TCP stream reassembly, traffic normalization, DNSGuard, FloodGuard, FragGuard, MailGuard, IPVerify, and TCP intercept to protect against Denial-of-Service (DoS) attacks, fragmented attacks, replay attacks, and malformed packet attacks. These technologies are employed to assure you that your information and system is protected from any sort of attack that outsiders may try to initiate.
Fraud Protection
Phishing, also sometimes referred to as brand spoofing or carding, is another method spammers today are using that has very dangerous implications. Phishing involves sending Emails to users posing as an established, legitimate enterprise such as a bank, in an attempt to scam the user into providing private information to be used for identity theft purposes. These Emails may direct a user to visit a specific site where they are asked to update personal information which could include passwords, credit card numbers, bank account numbers, social security numbers, etc that the legitimate organization already has. This website however, is actually fraudulent and is just a means to steal this information for illegal purposes. As you can see, this sort of activity is unlike your typical annoying spam in that it actually poses a real threat to your users. We protect your environment from these dangerous phishing scams so that you can be sure your users enjoy the best protection possible.
Directory Harvest Attack Prevention
A relatively newly expanding method spammers are employing is Harvesting Directories and Denial of Service. Directory Harvest Attacks (DHAs) are designed to provide spammers with growing lists of valid email addresses. Typically, an open source Mail Transfer Agent responds to email attempts verifying the validity of email addresses. This way, spammers have "harvested" lists of valid addresses to send spam to either for their own purposes or to sell to other spammers. Some studies show that during DHAs, an average of 30 percent of an email server's capacity is hijacked by spammers trying to steal confidential information. This is why we utilize technology that does not allow spammers to validate email addresses either way. In this manner, the spammers cannot identify specific addresses to harvest. With our solution you can be confident you're protected from these Directory Harvest Attacks.
Sender Authentication
One of the newest techniques we utilize in combating spam is by means of Sender Policy Frameworks. Using this approach, our email server authenticates the Internet domain of am email sender for legitimacy. Spammers are notorious for "spoofing" the domain that they send email from by hijacking it from an unsuspecting user or user group. Our SPF technology blocks out these messages that may otherwise not be caught by average filters.
