VPN Haus recently spoke with Rainer Enders, CTO of NCP engineering, about multi-tenancy in VPNs and its advantages. Stay tuned for part two of this conversation where we dive into some of the drawbacks of multi-tenancy and what it all means for enterprise users.

Q: What are the primary differences between a multi-tenant VPN and a standard VPN? How does virtualization play into the mix? 

Rainer Enders: Multi-tenancy in VPN typically refers to the presentation and management of customer-specific objects and information related to the customer’s VPN connections. On the access network side, the resources that are being accessed and used by the various tenants must be logically and securely separated. Virtualization techniques such as Hypervisors, VLANs, and VSANs, ease the burden of operation, maintenance and management in multi-tenant networks.  

Q: What are the advantages of running a multi-tenant VPN as opposed to running a single-tenant network?  

Enders: The benefits of multi-tenant capable VPN systems mainly appeal to service providers and network operators. Security service providers, cloud service providers or network service providers, in general, all are able to provision and manage VPN connections from different customer domains. As the security sensitive and relevant parameters are fundamentally different in the various distinct customer domains, keeping them separated from each other, for both security and manageability reasons, is critical. Another benefit in multi-tenant systems is that providers can offer easy and dedicated remote access while allowing the individual customers to manage and control certain aspects of the VPN securely, without compromising the privacy or security of the other customers and users.
