AntiVirus MultiScan

Retarus' Antivirus MultiScan technology provides powerful protection against virus-laden messages and attachments by utilizing up to four different virus scanners. The redundant, high-speed scanners check incoming and outgoing messages automatically (including attachments) for viruses. By means of heuristic analysis we detect even as-yet unknown malware.
 

• Higher detection rate with the use of up to four virus scanners
• Protection against unknown viruses through heuristic analysis (Zero-Hour Protection)
• Eliminate threats before it impacts your infrastructure
• Virus definitions updated every minute

Retarus AntiSpam

Our AntiSpam service checks incoming emails using continuously updated rules and tools for spam detection. Once classified as a spam message, depending on your service settings the Retarus service will mark the message or isolate it in the Retarus quarantine system. With our innovative technologies Retarus' multilingual anti-spam service will achieve a significantly higher detection rate than conventional anti-spam tools.

• Spam protection with a detection rate over 99.95 percent
• False-positive rate of less than 0.0001 percent

• Multilingual content analysis by means of over 3,000 rules
• Content and structure analysis using heuristic modeling
• Fingerprint analysis, Bayes algorithms, and sender verification
• Continuous updates of intelligent filter-, pattern- and recognition rules

Quarantine Management

The digests, which we send you at individually definable points in time, provide you and your staff an overview of all intercepted spam and virus messages. From there, any message that is classified as spam can be quickly released from quarantine without the need to access a portal. Additionally, we offer online access to the Retarus quarantine with simplified user authentication (OneClick token login). This quick login makes it possible to search for specific messages. We also offer an online quarantine version for mobile devices such as BlackBerry, iPhone and Windows Mobile.

• Quarantine of spam emails, optionally with online access
• Combined spam and viruses reports by email
• User-based quarantine and report settings
• Direct request of messages without authentication
• System-wide configuration via EAS portal for administrators

Quiet Time

With Quiet Time, you can define time periods, such as evenings and weekends, during which no external emails will be sent to your employees. Instead, inbound emails are stored in the Retarus data centers and automatically delivered to the intended end device once the retention period has elapsed. A bypass feature for high-priority emails and an emergency button both help to ensure that emails that need to be dealt with quickly are immediately delivered to the intended recipient.

• Configuration of email-free periods (external emails)
• Individual settings for various user profiles
• Secure temporary email storage in the Retarus data centers
• Automatic delivery of emails once the retention period has elapsed
• Bypass feature for high-priority emails
• Emergency button for immediate delivery of emails during email-free periods

E-Mail Size Reduction

Retarus E-Mail Size Reduction removes unnecessary parts, such as invisible elements in the header or alternative email body text (HTML, plain text), from incoming emails. File attachments are compressed automatically on request (ZIP function). These measures help reduce the size of inbound emails by as much as 30 percent, with no loss of information for the user. The simplified coding means better and faster presentation in the email client. And you save a huge amount on costly storage and backup capacity.

• Reduces data volume by as much as 30 percent
• Compresses attachments (ZIP) and recodes text parts on request (e.g. Quoted-printable to 8-bit MIME)
• Removes superfluous header information and alternative email body text
• Takes the strain off the email server and the backup infrastructure, saving costly storage space
• Faster, better email display thanks to simplified coding

Data Leakage Prevention

The theft of sensitive data, for example production plans or customer contracts, can put a company's very existence at risk. With Retarus Data Leakage Prevention you can prevent data from being undetectedly sent out by email, thus protecting confidential data effectively. Users can only send out emails if a supervisory authority or a designated function mailbox is included in the distribution list. Checks can then be made on a random sample basis and/or if misuse is suspected. This enables you to meet compliance requirements efficiently.

• Definition of supervisory entities for email transmission
• Granular configuration options on profile, group and user level
• Definition of exceptions on the basis of blacklists and whitelists
• Effective protection of company data
• Improves the quality of email communications
