VPN or IP VPN
What is the right choice for your business?
Virtual Private Networks (VPNs) and Internet Protocol Virtual Private Networks (IP VPNs) have a key difference. When choosing what option is best for your company, it’s integral you know what service you’re getting without a veil of smoke and mirrors in the way.
First of all, what is a VPN and an IP VPN?
A VPN is a networking technology that allows users to connect over a public internet connection to their main network remotely. A VPN allows employees to work from home and connect to the company’s intranet, giving them access to all the shared network files of their office computer.
An IP VPN works in much the same way, establishing seamless connectivity to a main network across an ISP. The difference is that an IP VPN utilizes multiprotocol label switching (MPLS) technology to prioritize internet traffic and avoid public gateway to increase security, making it a layer 2 service.
What’s the Difference?
Did you spot the difference between the two? VPNs and IP VPNs are very similar, but the most important difference is the layer of the OSI Model on which they’re classed.
Typical VPNs fall under layer 3 and 4, meaning they establish a connection through public internet and frequently use a public gateway to connect. By using a public gateway, VPNs are exposed to DoS (Denial of Service) attacks that decrease speeds and valuable bandwidth.
An IP VPN is considered layer 2, meaning it avoids public internet by traveling on a private connection to each remote site, so your vital company data remains secure.
Plus, as a layer 2 service, IP VPN uses MPLS capabilities that prioritize your company’s internet traffic, so critical applications like video conferencing and digital voice are guaranteed the bandwidth they need to perform.
So which option is best for your company, VPN or IP VPN?
VPNs work best for small businesses or sole proprietorships, where employees do not often need to connect to the company intranet remotely, and security is not a major concern.
IP VPNs are ideal for medium businesses to large enterprises, where multiple employees and branches need the ability to connect to the company intranet remotely and securely while handling sensitive corporate information. IP VPN is also useful for internet traffic that needs prioritization to better serve VoIP, video conferencing, and cloud services.
