Hello,Email gatewaysIt is typically used to move from one mail server to another, such as from an internal corporate mail server to an external mail server, or from an external mail server to an internal mail server.

Email gateways are typically software-based cloud gateways, but some are hardware-basedIt is recommended to consider the following points when choosing a reliable anti-spam gateway:

1.Stability of the anti-spam gateway

As the entrance and exit of the email system, the anti-spam gateway directly affects the efficiency of the mail server. High availability and high load performance are one of the criteria for verifying the stability of an email gateway.

2.Anti-spam effect

The main function of the anti-spam gateway is phishing, fraud and other spam, while ensuring the normal business email sending and receiving, it can effectively identify and intercept spam.

3.High interception rate and low false positive rate

A high interception rate and a low false positive rate are a very important indicator to verify the performance of anti-spam gateways. If the normal business email of the enterprise is also intercepted by the anti-spam gateway, then the normal operation of the enterprise employees will be affected.

4.Compatible with the mail system, full rotation of waiting

Common email systems on the market include Exchange, Domino, MDAEMON, Postfix, and Office365, and these email systems are perfectly compatible and easy to deploy.

5.IT operations management flexibility

The management and deployment of the reliable anti-spam gateway system should be flexible and convenient to minimize the workload of enterprise operation and maintenance personnel. The back-end logging system, query management system, and useful reporting functions should be at a glance to help IT administrators keep track of email sending and receiving details.

As the entrance and exit of the mail system, the mail gateway directly affects the efficiency of the mail server, and it is a good choice to choose a reliable anti-spam gateway. Hopefully, the above will help you choose an email gateway.

Email gatewaysThis can be a hardware gateway or a software-based cloud gateway, both of which can be leased to secure e-mail systems in a corporate network. For example, the anti-spam cloud gateway can not only realize the email filtering function, detect and block malicious emails, spam emails and phishing emails, etc., but also accelerate the overseas inbound emails, and also provide functions such as email sending and receiving log query.

Antivirus gatewayIt is usually used to protect all traffic and network security in the enterprise network, and to scan and kill data in and out of the gateway, including worms and web traffic. Antivirus gateways are usually used in conjunction with a network firewall and an intrusion detection system (IDS) to protect the network.

In short, both the email gateway and the anti-virus gateway can protect the security of the email system in the enterprise network, but their focus on protection purposes is different, the email gateway mainly protects the security of the enterprise email system such as spam filtering, phishing emails, etc., while the anti-virus gateway focuses on protecting the security of the email system network, as well as virus threats.

The difference between an email gateway and an anti-virus gateway is that the anti-virus wall only has the ability to scan and kill viruses in the packets passing through the gateway, and does not have the ability to control access.

The main function is to filter viruses while resisting spam, which is also directly related to the key conditions of enterprise email security, once there is a deviation and omission in any link, it may lead to the abnormality of the email sending and receiving status, so it is necessary to increase the application of Shanghai Qingyu's email products with advanced anti-spam technology to improve the level of enterprise email security.

After all, it is difficult to avoid hacker attacks on self-built mail servers, and if there is no professional product such as reliable email, it will face a large number of spam emails and passwords being cracked, but in the normal use process, you will find that the anti-spam cloud gateway function is powerful enough, and good spam and virus defense capabilities are quite intuitive to present the main functions.

Enterprise email security gateway is a kind of hardware or software gateway used to protect enterprise email system, reliable anti-spam cloud gateway as a security gateway for enterprise email has the following advantages:

1.Message filtering and detectionThe reliable anti-spam cloud gateway can detect and filter all emails in and out of the Huaidaqiao enterprise lead mail system in real time, and identify and intercept malicious emails and spam emails through a variety of technical means, such as anti-virus, anti-spam, anti-phishing, content filtering, etc., to prevent them from entering the enterprise network and employees' inboxes.

2.Threat protectionIt can monitor threats and attacks in the email system in real time, such as viruses, Trojans, worms, malicious links, etc., and prevent and intercept these threats through a variety of technical means, so as to ensure the security of the enterprise email system.

3.Security policy management: It can formulate and implement a variety of email security policies, such as sending rules, receiving rules, access control, audit logs, etc., to help enterprises manage email security and improve the security and controllability of the system.

4.Data backup and recovery: The reliable anti-spam cloud gateway can regularly back up the data in the enterprise email system, and support data recovery and emergency disaster recovery to ensure the integrity and reliability of the data in the enterprise email system.

5.Mail inbound acceleration: Intelligent DNS technology is used to divert domestic and foreign traffic, domestic mail is used for domestic bandwidth, and international mail is directly used for overseas dedicated bandwidth, and the reliable anti-spam cloud gateway accelerates email inbound with obvious effect.

To sum up, the enterprise email security gateway is one of the important security devices in the enterprise email system, and it can effectively prevent and reduce various security threats and risks in the enterprise email system through the powerful security functions and management capabilities of the reliable anti-spam cloud gateway.

Hello! The email gateway is a barrier that can filter advertising emails, virus emails, etc., and the better gateway services include Softnext, Cisco, etc.

Only on behalf of the opinion of the manuscript Tonghu, don't spray the bureau if you don't like it, thank you.

Email gateways and protocol converters work the same way. A gateway is essentially an IP address from a network to other networks.

The gateway implements network interconnection above the network layer and is the most complex network interconnection device, which is only used for the interconnection of two networks with different higher-level protocols.

Gateways can be used for both WAN and LAN interconnections.

A gateway is a computer system or device that acts as a translator.

Used between two systems with different communication protocols, data formats or languages, or even completely different architectures, the gateway is a translator.

With bridges only.

Simply conveying information is different, and the gateway has to repackage the received information to fit the needs of the destination system. Same layer - application layer.

A better one can achieve anti-spam and anti-virus, international mail sending and receiving, email archiving, email monitoring, but not all of them can, such as turbogate email gateway can be realized, and others will be less.

If you tell him so much, it is estimated that he can't understand it, and the ** of the email is generally not used, but if you are a business, you may use it.

A computer that transmits e-mail from one network to another, from one network to the Internet or, conversely, reformats header information if necessary.

Gateways used to be an easy-to-understand concept. In the early days of the Internet, the term gateway referred to routers. The router is a marker in the network that goes beyond the local network, and this "gate" to the unknown was, and still is, used to calculate routes and transfer packet data to parts of the source network, so it is considered the gateway to the Internet.

Over time, routers ceased to be magical, and the emergence and maturation of public IP-based WANs contributed to the growth of routers. Now that the routing function can also be performed by the host and the switching hub, the gateway is no longer a mysterious concept. Now, the router has become a multi-functional network device, which can divide the LAN into several network segments, interconnect the relevant LANs in the private WAN, and interconnect the various LANs to form the Internet, so that the router loses the original gateway concept.

However, the term gateway is still in use, and it is constantly being applied to many different functions, and it is no longer easy to define a gateway.

Currently, there are three main types of gateways: • Protocol gateway WNX"n • Application Gateway O: JWN • Security Gateway e-C The only generic meaning that is reserved is that it is a gateway as an intermediary between two different domains or systems, and the nature of the differences to be overcome determines the type of gateway required.

Turbogate is very good, you can ask for it.

Gateway: The gateway between two networks.
