Wireless VLANs can boost network security and protect business assets by segmenting traffic
Small business networks don’t have to be basic. In fact, they should apply some advanced networking technologies to their networks to get the same benefits as large enterprises, such as virtual LANs (VLANs). Just like larger companies, smaller businesses can use VLANs to bolster security, increase usability, and improve network performance. And with a wireless VLAN, you can segment wireless traffic on your network into groups that keep certain types of traffic separate from the rest of the traffic on your network.
A LAN is defined as all the devices that connect to each other in the same broadcast domain, whether that’s a wired or a wireless network. A VLAN uses software to create a virtual network of devices that are assigned to a broadcast domain; a wireless VLAN is like a separate, mini network within your wireless LAN. You can set up one or more wireless VLANs to support different groups of users, depending on their needs and the risks inherent to your company.

Another dimension of security is about maintaining overall device integrity regardless of the network (corporate or otherwise) it connects to.

You can provide guests with Internet access while ensuring the safety of your company data
I do a fair bit of traveling in my job. When selecting hotels, secure Internet access is one of my top criteria. It’s right up there with a comfy bed and fluffy pillows. I want to know that when I’m using the hotel network, I can access my corporate email or do online banking without having to worry about whether an intruder is prying on my Internet connection. It’s the same when I visit a client site. Clients very kindly let me use their Internet connection, but they want to ensure that I can’t snoop on their corporate network. Read More »
Increasing popularity of smartphones, laptops, and other WiFi-enabled devices makes the ability to get online wherever you are a necessity. In public areas, there are often hotposts and other public WiFi networks, but how do you connect when at someone else’s home? And when you host guests, do you ever feel awkward giving out the password to your wireless network?
