Security Features Summary

  • Anti-Spam Tools
    SecurityGateway for Exchange/SMTP contains multiple cutting edge tools to help control unwanted email. While no single tool detects all spam, their combined capabilities can reduce the flood of un-wanted messages to a trickle, without hindering the flow of legitimate communications.
  • Outbreak Protection (ProtectionPlus add-on required)
    By monitoring massive, worldwide outbreaks of new messages on the Internet, Outbreak Protection can automatically identify spam within minutes and sometimes within seconds of its release.
  • Heuristic and Bayesian engines
    Heuristics and Bayesian filtering takes advantage of your input to provide a tuned and personalised defense layer. By flagging messages as either spam or legitimate mail, this technology learns to automatically accept or reject messages based on your personal preferences.
  • DNS and URI Blocklists
    Use numerous trusted databases to quickly identify and block messages sent from or through email servers that are 'open relays' or known as spammers.
  • Greylisting
    This feature delays message acceptance from unknown senders by telling the sending email server to 'try again later'. In theory, most spam sources will not retry.
  • Message Certification
    When a message is certified, you can be sure it was sent from a source someone else says is trustworthy. Certified messages can be exempt from spam scanning.
  • Backscatter Protection
    Prevents receiving irritating bounce messages from messages you did not send.
  • Message Scoring
    Each domain can refuse, quarantine or tag messages based on customisable score thresholds.
  • Anti-Virus Tools
    SecurityGateway uses a combination of two very different but trusted virus engines, kept up to date by automatic updates at regular intervals. Flexible configuration options enable users to choose whether viruses are refused or quarantined for later review on a per-domain basis.
  • Clam AntiVirus
    ClamAV is a well trusted open source anti-virus engine, designed especially for e-mail scanning on mail gateways. Benefiting from a comprehensive up to the minute virus definition database, ClamAV provides accurate detection and also scalable performance.
  • Kasperksy AV (ProtectionPlus add-on required)
    Choose to add another layer of defense against viruses by complimenting ClamAV with Kasperksy's award-winning antivirus software. Protect your Exchange or SMTP server from trojans, spyware, rootkits and other malicious programs. Reactive detection methods are combined with proactive technologies to provide balanced and effective security, while automatic updates ensure uninterrupted protection and complete peace of mind.
  • Anti-Spoofing Tools
    An impressive range of cutting edge technology such as DKIM and SPF combine to ensure that any message sender is who they say they are, preventing spammers from forging the origin of messages.
  • DKIM (DomainKeys Identified Mail)
    The result of collaboration from both Alt-N Technologies and a number of other key industry players including Cisco, Yahoo! and Verisign, DKIM provides a method for validating a domain name identity through encryption. Messages are sent with a digital 'fingerprint', which is then validated upon receipt to confirm the signer's identity and to ensure the message was not tampered with during transit over the Internet.
  • Sender Policy Framework (SPF)/Sender ID
    Both of these security protocols are designed to detect spoofed email address using IP-based or path-based methods.
  • Reverse Lookups
    This feature checks the IP address of whichever server is sending you a message and cross-references it with details held about the domain on global DNS servers.
  • Call Back Verify
    This security option asks the sending server to verify the existence of the sending account before accepting the message.
  • Email Authentication
    Incorporates current authentication techniques used to validate and sign messages to minimize the receipt of possible spam messages.
  • Anti-Abuse Tools
    SecurityGateway for Exchange/SMTP contains a multitude of tools to detect and prevent the unauthorised use of your email server.
  • Relay Control
    Relay control limits authorised senders to those with email accounts only.
  • SMTP Authentication
    Specify that users must authenticate with a username and password in order to verify they have the authority to be sending messages through your server.
  • IP Shielding
    IP Shielding works using a database containing pairs of domain names/IP addresses. If a message comes from one of the domain names in the database, SecurityGateway knows it must come from a matching IP address otherwise the message will be blocked.
  • Dynamic Screening
    Dynamic Screening temporarily prevents connections by senders who exhibit spam-like behaviors.
  • Tarpitting
    This feature discourages spammers by slowing down their ability to send high volumes of messages to an email server within a specified length of time.
  • Bandwidth Throttling
    Limit the amount of bandwidth you can afford to allocate to email services to avoid slowdown of other services sharing the same connection.
  • Attachment Filtering
    This option quarantines messages containing specified types of attachments, such as Visual Basic scripts, executable programs and other user defined extensions.
  • Blacklists and whitelists
    Global, domain-specific and account-specific white lists help make sure users receive messages from their regular correspondents. Black lists at these same levels can make sure they do not receive messages from specified domains and individual senders. Specify trusted senders by using their domain, email address, host name, or connecting IP address.
  • Policy Enforcement Tools
    SecurityGateway incorporates the powerful SIEVE email filter language to minimize data leakage of sensitive or proprietary information, helping businesses adhere to both internal policies and industry regulations. With an intuitive GUI design, administrators can prioritise and customise the filtering process in order to better manage the ingoing and outgoing message flow.
  • Message content filter
    Allows the administrator to look for content within a message and take action based on the results.
  • Preset file types
    Allows the administrator to tell SecurityGateway to block all attached video files, images, or executable files with one click.

Admin Features Summary

  • Simple Installation
    Be up and running in minutes. SecurityGateway requires only a few basic configuration details such as the first email domain name. Accounts are added automatically in almost all installations.
  • Intuitive Web Based Control Panel
    SecurityGateway is 100% Web based for greater flexibility, and an intuitive interface design produces an easy-to-use understanding of features, configuration options and settings.
  • Per user/per Domain Controls
    SecurityGateway's per user and per domain options enable administrators to delegate responsibility for the editing, configuration and reporting for specific domains without having to grant server-wide access. In addition, user level features also include:
    • Individual Whitelists and Blacklists
    • Individual Message Logs
    • Individual Quarantine Management
  • Automatic Domain and User Creation
    Domains can be added automatically from verified and trusted email servers enabling practically hands-free maintenance of the domain and user base.
  • Individual Quarantine Emails
    Users can opt to receive periodic summary emails of any messages sent to them that have been trapped in the quarantine. A one-click, Web based system enables users to quickly review, and then accept or reject mesaages from within their mail client at the touch of a button.
  • Automatic Periodic Backup
    Periodic backups can be scheduled to prevent loss of the gateway data, including the logs and graphical reports. The system can keep all backups or only a specified number of recent backups. Message files, if available, are kept in the backup as well.
  • Message Management
    By viewing the message log, an administrator can see a list of all messages processed, along with information about the status of each message delivered, quarantined, rejected and why. This information can also be used for fine-tuning the filters.
  • Defense Layer Customization
    A unique control that allows global administrators the flexibility to prioritize the order of operations of SecurityGateway for Exchange/SMTP's multiple security features. Simple up and down arrows within the easy-to-use interface enable an administrator to change the order in which a specific security rule will execute when analyzing incoming or outgoing email traffic. This technique can result in faster processing of email by allowing the rejection or quarantine of messages at the earliest point during processing.

Reporting features
