The evolution of technology means that others, which bear more advantages than previous versions, can replace various applications. The primary purpose of both Direct Access and VPN is to provide users at a remote location with access to internal networks via the internet. As a result, the best solution is required to adequate user comfort while using the remote services. This paper explains the benefits of using Direct Access over VPN.
One of the edges that Direct Access has over VPN is the ability for automatic direct connection. The user need not initiate connection from their computer to the internal network. Furthermore, Direct Access works through all firewalls, whereas VPN is limited to some extent with its access to firewalls. Moreover, selected server access is supported, in addition to IPsec authentication in the cases of internet network servers. Furthermore, Direct Access provides support for end-to-end authorization and encryption for user data, thereby assuring that the user experiences high safety standards during their remote access operations. In addition, Direct Access has the options for computer management for remote users in whichever location (Wang, Iyer, Dutta, Rouskas, & Baldine, 2013).

Nevertheless, some limitations are present in the case of using Direct Access. Where other operating systems other than Microsoft are involved, Direct Access is not usable. However, VPN is a viable option. In addition, VPN is compatible with computers, which are not joined to a domain and does not need the remote access server to run Windows Server 2008. Notwithstanding, the end-user productivity is generally higher when using Direct Access, as the users enjoy the same experience that they have while at the office using an internet connection. Therefore, users can read their email, access shared information and enjoy the services of their internal applications without being connection to a private network. Overall, Trek would best be suited adapting the Direct Access software rather than the current VPN technology, as this will provide ease of access to its sales representatives traveling across the country.
