Multiple Antivirus Scanners plus Antispam Agent
Every email transiting through the ADVASCAN™ service is processed by up to five separate antivirus scanners. The first (two are standard, up to four may be used) are commercial scanners. The final scanner is the proprietary email filter engine ASSESSOR™. At each stage, when a scanner detects a virus, the email concerned is removed from the flow and deposited in a 'quarantine' storage area.
ADVASCAN™ also runs antispam processing on all emails through the system. ADVASCAN™ uses public black lists, customer defined black and white lists, plus a sophisticated proprietary algorithm for detecting unsolicited bulk email.
ADVASCAN™ incorporates a wide range of heuristic tests on mail headers and body text to identify spam. The spam scoring techniques used are under configuration control by the customer IT administrator, who can choose the criteria against which potential spam is dropped or deposited in a spam quarantine store for later examination and deletion.
Configurable Quarantine Rules
The separate quarantine areas for suspect emails have configurable parameters such as storage quota, number of messages, and time to hold messages before automatic deletion. Through the user-friendly web-based management tool, the customer IT administrator has full access to the quarantine areas to inspect and delete infected or unwanted emails.
Web-Based Statistics and Management Reporting
The IT administrator is given secure access to a web-based 'front end' from where he can manage all configurable features of the ADVASCAN™ service, and generate reports and statistics relating to virus incidents, spam and general email usage and volume per user account. Through this interface the administrator also has the ability to add and delete individual user accounts, and even switch them in or out of the ADVASCAN™ service altogether.
Notifications
Whenever the system detects and quarantines a virus-suspect email, a message can automatically be sent to both the sender and recipient of the email. Additionally, an email alert is sent to the IT administrator. For normal emails passing through the system, a brief footer is appended explaining that each email has been scanned by ADVASCAN™ and is virus-free.
