Virtual Private Network (VPN) and Internet Protocol Virtual Private Network (IP-VPN) have several differences. When choosing what option is best for your company, it is very important that you know what service you are getting First of all, what is a VPN and an IP VPN? VPN is a network technology that allows users to remotely connect via a public internet connection to their main network.
A VPN allows employees to work from home and connect to the company intranet, giving them access to all shared network files on their office computers. IP VPN works in much the same way, establishing seamless connectivity to major networks across ISPs while leveraging multiprotocol label switching (MPLS) technology to prioritize internet traffic and circumvent public gateways for increased security.
What is the difference? VPN and IP VPN are very similar, but the most important difference is the layer of the OSI Model in which they are classified. Typical VPNs are below layers 3 and 4, meaning they make connections over the public internet and often use public gateways to connect.
By using a public gateway, a VPN is subject to a DDoS (Distributed Denial of Service) attack which slows down valuable speed and consumes valuable bandwidth. IP VPN is considered layer 2, meaning it circumvents the public internet by traveling using a private connection to any remote sites, so your important company data stays safe.
Additionally, 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 needed to run them. So which option is best for your company, VPN or IP VPN? In general, a VPN works best for small businesses or individuals, where employees often don’t need to connect to the company intranet remotely, and security is not a major concern.
IP VPNs are ideal for mid-sized businesses to large companies, where multiple employees and branches need the ability to connect to the company intranet remotely and securely while handling sensitive company information. IP VPN is also useful for internet traffic that needs to be prioritized to better serve VoIP, video conferencing and cloud services.
