Roaming VPN
The Only Enterprise VPN That Seamlessly and Securely Combines, Optimizes and Transitions Between Wi-Fi and Cellular Networks, Boosting Throughput 2x to 10x or More
The Only VPN with Massively Scalable Back-end Optimization that Delivers 2x to 10x or Greater Improvements in Throughput by Eliminating Wasted Bandwidth
Today’s streaming applications, cloud environments and wireless networks increasingly generate jitter – now the leading cause of throughput collapse, resulting in video that randomly pauses, stalled applications and dropped connections, even when plenty of bandwidth is available. This means a large percentage of bandwidth is wasted, killing network performance as well as employee productivity. Paying for more bandwidth isn’t the solution!
Roaming VPN includes the only patented back-end network optimization solution capable of eliminating jitter-induced throughput collapse for all types of traffic – encrypted, unencrypted or compressed. Bandwidth previously lost to jitter-induced throughput collapse is recaptured, resulting in 2x – 10x or greater improvements in throughput. Roaming VPN delivers these impressive results with unmatched scalability, supporting network traffic speeds of more than 1 Tb per second, with over 10 million simultaneous sessions and 50,000 new sessions per second. Roaming VPN’s back-end network optimization component is single-ended and can be installed in an on-premises data center, or as a VM in a cloud environment.
Only Roaming VPN offers Seamless Channel Bonding that Combines, Optimizes and Continuously Transitions Between LTE and Wi-Fi Connections Without Packet Loss or Performance Degradation
Wireless network environments are crowded with Wi-Fi hotspots, LTE dead zones, and constant switching between LTE and Wi-Fi, and from one Wi-Fi network to another. Roaming VPN hides these transitions and eliminates packet loss, as it combines and optimizes the bandwidth of all the user’s available connections. Users have the experience of always being on a single high-performing network, even when they’re constantly changing locations.
Wireless networks are also frequently subject to RF interference, fading and channel access conflict, creating jitter that leads to throughput collapse over the entire network path between the user’s mobile device and the application server, not just the wireless segment. Only Roaming VPN overcomes this by combining its patented back-end network optimization component on-premises or in the cloud, with its VPN application on the user’s laptop or other mobile device.
Roaming VPN offers the Ultimate Security Solution for Both the Employee’s Mobile Device, and their Employer’s Network and Data
Roaming VPN uses the latest VPN encryption technologies, and ensures that payload data, including tunneling headers, are hidden from public view. In the back-end network, Roaming VPN’s next generation optimization uses an algorithmic approach that requires no payload access. Traditional dual-ended optimization tools that need unencrypted payload access for de-duping and compression add encryption/ decryption delays at each endpoint that slow performance, in addition to imposing the maintenance overhead and security risk of exposing sensitive data and encryption keys to a third-party solution – significant drawbacks now that over 80% of internet traffic is encrypted.
Only Roaming VPN Fills the Performance and Security Gaps as Enterprises Adopt SD-WAN for their Move to the Cloud
SD-WAN’s rapid enterprise adoption has accelerated with the move to the cloud. The reason is SD-WAN enables internet traffic to be offloaded from leased line and MPLS links to less expensive broadband, allowing direct branch office-to-cloud and branch-to-internet connectivity. The architectural and cost advantages are obvious. However, enterprises typically make two faulty assumptions when they select an SD-WAN solution:
- The first faulty assumption is that SD-WAN can optimize performance by choosing the best available network path among broadband, LTE, 5G, MPLS, Wi-Fi or any other available link. The problem is that SD-WAN makes decisions based on measurements at the edge, but it has no control beyond that. What if all paths are bad? Some SD-WAN vendors bundle network optimization solutions to address this. However, these tools typically rely on de-duping and compression techniques that do nothing to address jitter-induced throughput collapse, and even make it worse for the more than 80% of internet traffic that’s encrypted by requiring payload access that adds encryption / decryption overhead. In cloud environments, VM crosstalk and hypervisor packet transfer delays compound jitter from hosted applications that transmit data in random bursts, contributing to throughput collapse before traffic even enters the network. Only Roaming VPN’s back-end optimization, whether in the cloud, or an on-premises data center can address these issues and improve performance for all types of traffic.
- The second faulty assumption is that because most SD-WAN vendors offer IPsec, SD-WAN must be secure. The problem is SD-WAN bypasses MPLS VPN connections that funneled all traffic to a corporate data center where security policy was applied before moving on to its destination. Even though IPsec protects traffic as it moves from branch office-to-cloud, there’s no protection for break-ins or malware for direct branch-to-cloud traffic. You often have to create an IPsec VPN overlay by deploying devices at the branch office and cloud head-end. This will require additional infrastructure and management tools, unless you use Roaming VPN.
Roaming VPN Offers the Lowest Possible Mobile Device Power Consumption
In head-to-head tests against other VPNs that feature channel bonding, Roaming VPN demonstrated the lowest mobile device battery consumption – nearly 50% less than the closest competitor. Employees will turn off a VPN that drains their battery, preventing enterprises from taking advantage of the cost-savings, security and productivity improvements a VPN can offer.
Roaming VPN Future-Proofs Enterprise Networks for 5G
The rollout of 5G will result in constant 5G to Wi-Fi transitions as in-building Wi-Fi becomes the fallback for blocked high-frequency short range 5G signals that can’t penetrate building walls and energy efficient windows. Another important factor is that during the transition to 5G, LTE will serve as the backup network for 5G, just as 3G has for 4G, requiring frequent switching between them.
In addition, 5G networks will require at least 10 times the number of cells due to shorter signal ranges and higher frequencies, making jitter due to fading and RF interference an even greater factor. Roaming VPN’s back-end optimization that eliminates jitter-induced throughput collapse, combined with its mobile device VPN application’s seamless, secure transition between wireless networks will be even more critical with 5G.
