Features

Multiple Domains and Servers Support
ShareTech MA supports multiple domains and mail servers (for example, you can create sharetech.com.tw & tpsharetech.com.tw). An email with its attachments will be transferred and archived based on administrator-defined policies.

Mail Gateway
To couple with industry-leading real-time antivirus and antispam scanning, ShareTech MA provides fast and accurate email security that does not affect end-users or delay their communications. MA Servers can be deployed in the gateway mode to defend your mission-critical email systems.

Dual Anti-Virus Engines
MA offers built-in ClamAV and Kaspersky modules for virus scanning. ClamAV, having automatic signature updates, can detect millions of Trojans, viruses, malware & other malicious threats, reducing business IT costs. Moreover, clients with more demanding security needs can purchase Kaspersky modules, ensuring a rapid response to new attacks. The system will generate filter reports and notify users whenever a suspicious email is quarantined.

Multi-Layered Spam Filtering
ShareTech MA employs multi-layered spam filtering, including keyword/hyperlink filtering, multi-RBL check, ST-IP network rating, greylisting, Bayesian filtering, fingerprinting, and spam characteristics to filter out unwanted bulk email messages before system overload. Personal black/whitelisting can be defined and enforced flexible policies for high-accuracy spam filtering. Moreover, the system provides link filtering with a database to avoid receiving emails with malicious links.

 

Spam Mail Auto-Learning System
Phishing techniques are more and more challenging to deal with nowadays. ShareTech developed a spam mail auto-learning system to analyze emails' details and find the possible danger. Through data sharing, the auto-learning system will handle all the complexity of spam mail issues and stop malicious attacks.

ShareTech Sandstorm-Malicious Programs Filtering System
Event logs record all the happenings on the device and bear clues to several security hacks and application performance issues. It is a tedious task for an administrator to check and track issues on each device manually. MA provides a solution to handle complete network fault management from one window. Administrators can search through events logs efficiently for evidence of a particular event.

Email and Personal Data Auditing
MA provides policy-based auditing controls. Security policies can be created and prioritized by the system administrator in the user interface based on governmental regulations or internal business processes. Incoming and outgoing emails are handled according to recipients, senders, subjects, size, attachments, etc. Moreover, MA protects personally identifiable information such as ID number, credit card number, phone number, mobile number, and date of birth. Actions such as forwarding to administrators, deleting, sending carbon copies, or sending notifications can be performed to certain emails that trigger the filtering rules.

Mail Archive Retrieval and Inspection

In addition to simply archiving all inbound, outbound, or internal email, MA protects organizations' emails from accidental deletion, provides email resumes, and allows for quick searching and data retrieval in the email archive. The system allows users to enter a keyword or conceptual search query on web-based interfaces to search through all fields, including domain, subject, content, attachment, sender, recipient, date, attachment, and more. Users can either read or retrieve crucial documents for investigations.

 

Email Record, Archive, and Backup
Storage can be divided into two main types: Localhost and remote.

   Localhost Storage

2TB HDD built for use in MA-400. By default, archiving policies can be applied to move email messages automatically to the archive database, and the system will keep your backups for 7 days.

   Remote Storage

USB flash drive, FTP, and SAMBA are supported for users to retrieve individual messages through Network Neighborhood in a failover. MA can connect to multiple storage servers simultaneously so that administrators can search for archived messages, inspect their contents, and retrieve them easily from within their archive database.

 

Securely Backup Office 365 and Gmail
MA backup solution supports cloud-based storage platforms by creating hybrid clouds, giving businesses greater flexibility. MA can integrate with two generally available cloud-based solutions among businesses: Google Workspace and Microsoft Office 365. In addition to applying in-place archiving and auditing policies to business email messages, data can be securely stored in different geographical locations as an off-site backup.

Multiple Server-Based Password Authentications
Using multiple user authorization methods is desirable for SMBs, and ShareTech MA supports RADIUS, AD, POP3, IMAP, LDAP servers, and Google OAuth for authentication. A valid username, password, and full email address are required to connect to these authentication servers.

Role-based System Administration
Role-based system administration provides distributed management and distinguishes between administrators and ordinary users. After securely assigning different levels of initial accesses, users have fully integrated functionality to grant, manage, and revoke items such as system management, SMTP server, bridge mode, domain management, and authentication across internal and external organizations.

Event Logs Analyzer
Event logs record all the happenings on the device and bear clues to several security hacks and application performance issues. It is a tedious task for an administrator to manually check and track issues on each device. MA provides a solution to handle complete network fault management from one window. Administrators can search through events logs efficiently for evidence of a particular event.

Personal Archive Interface
A personal archive interface with three privilege levels (domain, department, individual) allows users to search with different columns, including sender, receiver, subject, content, date, etc. For users accustomed to the Outlook interface, Outlook Plug-in is available to search archived emails directly in Outlook.

Individual Mailbox Backup & Restore

ShareTech MA provides an easier way to perform individual mailbox backup and restore. When hard drive failure or unforeseen circumstances occurs, the system allows users to directly resend email stored on the MA appliances to designated accounts.

 

Personal Dashboard
Unlike traditional reporting, MA provides a dynamic personal dashboard in the web user interface (web UI), presenting a graphic view of personal email statistics. Users can specify a date range to analyze their ordinary email, spam, and virus-infected email activities. Pie charts and bar charts are used to display query results. Users are given more visibility into their email flow statistics with data visualization.

User-Friendly Web UI and Custom System Configuration

With web-based configuration utility and firmware upgrade, MA provides an interface that allows users to change their language preferences (Traditional/Simplified Chinese and English) and enable/disable HTTPS remote control services. Additionally, administrators can change names on browser tabs, login pages, and servers.

 

Unrestricted-User Accounts
MA has no restriction on maximum licensed users. Performance varies considerably depending on hardware and network traffic. The system provides regular firmware and predefined attack-signature database updates without additional charge. Moreover, integration with ShareTech Eye Cloud management reduces the cost of ongoing support and maintenance for budget-conscious businesses.

     ShareTech Mail Archive (MA) supports 3 Architectures: Bridge, Gateway and POP3 Proxy

  Bridge Mode

MA-400 supports 2-pair LAN bypass for Ethernet connection. The MA appliance can be deployed in front of a major mail server. When configured in Bridge Mode, it can record email messages and provide security services. Due to other email clients like Outlook and Thunderbird are widely used in the business world, the MA Series appliances can filter SMTP protocols while capturing, store and archive all inbound and outbound email messages.

 

   Gateway Mode

MA-100 can be an email gateway that filters your organization's inbound and outbound email to protect users from virus and spam. To protect internal mail servers from outside attacks, gateway mode usually demands more computational resources. Outlook users can point SMTP service at MA-100 to apply email auditing. Moreover, gateway mode is also suggested to companies that build mail server on virtual machine and are not able to receive traffics running in bridge mode.

 

  POP3 Proxy

ShareTech MA Series can operate in POP3 proxy mode and automatically archive all inbound and outbound email messages as they pass through, using a process called Journaling. Email systems such as cloud-based exchanges (Gmail, 163, and Microsoft Office 365) and internal servers (Microsoft Exchange Server or IBM Lotus) are supported. In this way, email communication can all be archived to the organization’s mail archive appliances. By choosing POP, users can continue to use their preferred email services and search through all their emails in a single archive view.
