Outline
Situation. Mobile devices are challenging the traditional VPN model
The virtual private network is still seen today as the most secure and practical data
communications solution for both companies and end users. 1
However, the tradi-
tional VPN is very task-specific. Staff outside the company set up a connection to
the corporate network on their laptops or PCs, in order to edit documents. After ac-
cess to the documents, the connection is severed again. The arrival of smartphones
and tablets in the corporate world and the changing behavior of users mean that
the standard VPN is in many cases no longer sufficient.
Problem.
Many variables make it harder to adapt VPNs to smartphones and tablets
Depending on the security requirement and user behavior, you may be faced with
the following issues regarding the virtual private network: “I offer BYOD and want
only the business apps to use the VPN connection.” Or: “I want every instance of
data communication that is sent from a mobile device to be routed via the VPN.” Or:
“What happens when the VPN server has to decide which website or app can go
through the tunnel, how does the device cope with that?” In addition to security and
user behavior, you also need to check the technical preconditions. These include
the possibilities of your VPN provider, of the mobile devices, and of the mobile
operating system.
Solution. Find the right virtual private network with iOS
Since iOS 8, Apple has been offering its customers a wide range of VPN settings.
This can satisfy the full extent of your security requirements and cover the antici-
pated user behavior of your staff. With iOS, you as a company have the benefit that
the device and the operating system are one and the same, and thus easier to
manage. However, iOS is not the answer on its own. A suitable enterprise mobility
solution that supports the different VPNs is also important. The VPN provider must
also work smoothly with the enterprise mobility solution and the iPhone/iPad.
Result.
VPN, Cortado Corporate Server, and iOS: The perfect threesome for security
Thanks to a perfect combination, consisting of the Cortado Corporate Server enter-
prise mobility solution, the appropriate type of VPN, and iOS 8, the door to secure
and successful implementation of enterprise mobility is wide open. From now on,
your staff will work securely and productively and thus you will create the basis for
your mobile company.
