There are also security downsides to having full access to a machine on the network, including access to local files as well as network resources with the full permissions of that user.

Is VPN a third party?
However, for a third-party needing access to provide support, a VPN is merely the first step. Additional layers of access would need to be added in order for them to access the servers or hosts to be supported. For instance, if you will be supporting a server, you need credentials on that server and the proper rights-levels to do the work. This is, at minimum, a two-step process (you might need credentials on multiple hosts) which allows for human error and active maliciousness to cause issues or problems. On the converse side, they may be provided with too much access and that access may not be tracked adequately. Once the job is done and the contract’s terminated, credentials and VPN access must be removed in a timely manner. If not, this provides a window of vulnerability into those services and devices. And if a user’s credentials are stolen or co-opted, the amount of damage that can be caused is greatly increased by a VPN’s broad network access.
Is VPN good for third party access?
