Top 11 Network Security Software For Small To Medium-Size Business (SMB)

If you run a business, especially one that deals with valuable information, you can never have too much security. There is a world of hackers trying to get into your system to steal information. With the dangers of hackers, there are also varmints such as spyware, viruses, spam mail and pop-ups trying to get into your computer network. Some of these intruders such as spam mail and pop-ups are simply bothersome while some can be destructive to your computers if you allow them in. In today’s world, there are also threats from inside your computer network, an area once viewed as safe. Like software that protects your computers from outside threats, network security software can cut down on threats that come from inside your own network.

As mentioned, network security comes in two varieties, internal and external. External means protecting you system from network security threats that come from any place other than inside you internal network or LAN. Internal security protects your system from intrusions on the network you own. An example would be an attack by one of your own employees.

There are several ways to handle the problem of computer network security. These all involve adding something to your network internally. If you decide to go the security software route there are several companies that offer solutions. Some companies only offer firewall protection. If you are only going to be running a web-server this may be the only protection you need. If you need to protect your personal computer, the one you use to keep tax and bank records on, surf the net, and open emails, you may want to consider an Internet security suite. There are many companies offer Internet security suite solutions to choose from. Make sure to pick one that will protect you system from viruses, spam, pop-ups, spyware, and hacker attacks with one program.

If you decide to go the hardware route for network security, then you will have to buy equipment that you must program and setup properly to work with your network. Just like software driven security, hardware security offers a wide range of protection. Also like software, hardware is customizable to your applications. However, hardware security platforms offer much more security than software, simply because these appliances stand alone and are not tied to the computer the hacker or virus might be trying to infect. This hardware simply gives hackers or viruses one extra layer of protection they would have to penetrate to gain access to your network. Obviously, a combination of hardware and software is the ultimate in network security, adding more layers or protection.

Whether you are using network security software or hardware on either an internal or external network, the goal is the same – an intruder free system with zero down time. Why? Because downtime means zero productivity and zero productivity means zero profit.
