Antispam Appliance vs. Antispam Filtering Software
The difference between an antispam appliance and antispam filtering software is that the antispam appliance is hardware that is used on larger networks to filter and block spam from entering the email server. It also allows the user to communicate securely online with different programs without receiving spam as a result of their online activities.
On the other hand, antispam filters are software that is designed for smaller systems and individual PCs on a network. If you are a large organization, antispam filtering software is not as effective as an antispam appliance, due to the fact that the appliance is hardware which can provide more capabilities for spam protection and email security.
How an Antispam Appliance Works
Since an antispam appliance is hardware, it can be placed at the entry point of the email server to inspect and filter every message that enters the email server. An antispam appliance is capable of evaluating IP addresses that are included in the email messages from the sender. The appliance can also examine the message content and then compare it against the criteria and parameters that have been set for receiving email messages.
Advantages of an Antispam Appliance
Antispam appliances are capable of providing more email security to large networks because it is hardware that is specifically designed to handle email security on larger networks. Also since an antispam appliance is hardware it is much easier to install and configure on a network, as opposed to software that may require a specific operating system infrastructure. For example, if the organization is running the Linux operating system, this type of system will not support antispam filtering software.
Another advantage of using an antispam appliance is its ability to protect a large network from codes that are designed to destroy the individual computers on the network. These are malicious codes that can enter the email server and then transmit to the email client via spam. When the individual computers get infected, it slows the productivity of the organization and interrupts the network processes.
Although many large networks deploy a vulnerability assessment program that can protect the network against criminals with malicious intent, sometimes vulnerability assessment is not enough to protect the massive amounts of email that enter an email server on a large network. This is why it is important to deploy an antispam appliance to provide added security for your email server and the email clients on the individual computers that are connected to the network.
