Mail Sentinel anti-spam and Mail Sentinel anti-virus subscription options build upon the capabilities of Mail Sentinel's basic feature set to help ward off malicious spam and viruses. Mail Sentinel's subscription options are used to add an additional layer of strong defense at the network's perimeter by implementing an extraordinary gateway-level solution.
GTA has integrated the ‘best of breed' in anti-spam engines from technology leading Mailshell into Mail Sentinel's subscription options. Mailshell's anti-spam with SpamCompiler AITM technology compiles, optimizes, and executes over 300,000 checks in fractions of a second to determine whether or not a message is unsolicited spam.
Mail Sentinel anti-spam
The Mail Sentinel anti-spam subcription option is a fully customizable, easy-to-use SMTP spam blocking solution. There is no additional software to install on your GTA firewall UTM Appliance. Activation and configuration of the subscription option is a simple process.
Mail Sentinel Anti-Spam's greylisting settings offer enhanced email filtering before the email reaches the email server. Greylisting is designed to protect users from spammers that use "fire and forget" email applications, which are created to send spam messages, but never attempt to retry delivery if the first attempt fails. Greylisting significantly reduces the number of emails which are scanned by spam rules, so email processing is more efficient. With a two pronged attack on email, spam is virtually eliminated while legitimate email is efficiently processed and received at the user's inbox.
Mail Sentinel anti-spam is powered by MailShell Anti-Spam's spam Recognition System. Each message is reviewed by four separate spam identification engines that utilize over 300,000 rules to identify unsolicited email. Mailshell's four spam identification engines check for a variety of characteristics that exhibit spam-like behavior, such as spam attacks, phishing techniques, image spam, and others. This unique spam identification system provides a high accuracy rate, all while preventing false positives.
The result of the proprietary Bayesian engine are combined into a SpamScore, a final spam probability rating. Messages with a high rating are flagged as spam, while messages with low ratings are delivered to their destination. Administrators can establish thresholds based on SpamScores for confirmed and probable spam to fine-tune spam filtering to match corporate needs. Once Mail Sentinel anti-spam thresholds have been established, administrators may choose to accept, reject, tag or quarantine confirmed or suspected spam.
GTA firewall UTM Appliances with the Mail Sentinel anti-spam subscription option receive automatic updates to ensure the accurate weighting of rules when formulating the SpamScore probability rating. With automatic updates, network administrators can rest assured knowing Mail Sentinel anti-spam remains up-to-date to combat the latest spam tactics.
Mail Sentinel anti-virus
The Mail Sentinel anti-virus subscription option is your first line of defense against virus attacks. Activating the Mail Sentinel anti-virus option on your GTA firewall UTM Appliance's email proxy results in real-time scanning for viruses and other malware that is preformed at the perimeter before they reach your network. Multiple updates per hour ensure that you are getting the best protection from virus infections.
Mail Sentinel anti-virus provides reliable virus protection based on time-proven virus detection algorithms such as pattern matching, behavior emulation and heuristics. Even unknown viruses are detected and prevented using proactive virus detection mechanisms, providing sought after zero-day protection.
When using Mail Sentinel anti-virus, each email message is quickly scanned and its contents reviewed against a growing database of nearly 100,000 virus definitions that includes malware definitions for classic viruses, network worms, trojan program, DoS and hacking tools, flooders and virus writing tools. If a virus is detected, Mail Sentinel anti-virus will disinfect the contents when possible. Network administrators can customize how email is handled with choices to accept, reject or even quarantine email that is known to contain a virus. Email containing viruses can be tagged for easy recognition by the end users, who can then choose to filter tagged messages using email rules.
All GTA firewall UTM Appliances with active Mail Sentinel anti-virus subscriptions automatically receive periodic updates of virus definitions to ensure effective and accurate virus protection. As new virus definitions are discovered, your GTA firewall UTM Appliance is updated to provide the best possible protection against email based virus attacks.
