What is VPN?

Over the last ten years, the IT landscape has shifted dramatically. New developments in cloud and mobile have transformed IT technologies (think about file sharing and Box). Networking, however, has struggled to keep pace.

VPN or a “virtual private network” is essentially a secure “tunnel” that connects remote employees with network resources. Generally, VPN servers and clients support remote access to an intranet, support connections between numerous intranets within one organization, or form an extranet that joins networks between two organizations.

VPNs are traditionally hardware-based, require hours to setup and configure, take money to maintain and upgrade, and still pose connectivity issues for remote workers.

VPN solutions rely on a variety of different network protocols including L2TP, PPTP, SOCKS and IPsec. VPN users usually interact with basic graphical client programs, and the physical infrastructure is generally comprised of numerous VPN hardware and software products that require service and upgrades from time to time.

For a while, traditional networking did its job pretty well, but today’s era of cloud and worker mobility is bringing new opportunities for VPN development.  The rise of the mobile workforce and BYOD (bring your own device) have created serious new challenges for IT pros, who are responsible for ensuring that workers can connect with one another and crucial information without exposing communications or data to prying eyes.

As workers become highly mobile and organizations shift workloads to the cloud, hardware-based networks are becoming constraining, complex, and inefficient. The rise of BYOD (bring your own device) also poses problems, since windows-based management and security paradigms don't extend to smartphones, tablets and Macs.

To escape the continuing expenses and headaches associated with traditional VPN, Pertino invented networking for the cloud and mobile era. In just minutes, and without any hardware or configuration, IT professionals can create fully-functional business networks. It’s simple to manage theses networks and the people on them via Pertino’s management dashboard.

As more companies move away from constraining hardware-based VPN and move networking to the cloud, IT professionals will have more time in their days, more budget, and fewer help desk calls.
