VPN allows users to use an easy to set up Internet infrastructure, allowing new users to quickly and easily add to the network. Read on to know advantages and disadvantages of VPN’s.

1. VPN’s advantages and disadvantages
1.advantage
VPN enables mobile employees, remote employees, business partners and others to
connect to the enterprise network using locally available high-speed broadband
network connections (such as DSL, cable TV or WiFi network). In addition, high-speed
broadband network connection provides a cost-effective method of connecting
remote offices.
Well-designed broadband VPN is modular and scalable. VPN allows users to use an
easy to set up Internet infrastructure, allowing new users to quickly and easily add to
the network. This capability means that enterprises can provide a large amount of
capacity and applications without adding additional infrastructure.
VPN can provide a high level of security, use advanced encryption and identification
protocols to protect data from prying, and prevent data thieves and other
unauthorized users from contacting this data.
Full control, virtual private network enables users to use ISP facilities and services,
while fully mastering the control of their own network. Users only use the network
resources provided by ISP, and other security settings and network management
changes can be managed by themselves. You can also establish a virtual private
network within the enterprise.
2. Shortcoming
Enterprises cannot directly control the reliability and performance of Internet-based
VPN. Organizations must rely on Internet service providers that provide VPN to
ensure the operation of services. This factor makes it very important for enterprises
to sign a service level agreement with internet service providers. It is necessary to
sign an agreement to ensure various performance indicators.
It is not easy for enterprises to create and deploy VPN lines. This technology requires
a high level of understanding of network and security issues, and requires careful
planning and configuration. Therefore, it is a good idea to choose an Internet service
provider to run most things of VPN.
VPN products and solutions of different manufacturers are always incompatible,
because many manufacturers are unwilling or unable to comply with VPN technical
standards. Therefore, mixing products from different manufacturers may cause
technical problems. On the other hand, using equipment from one supplier may
increase costs.
When using wireless devices, VPN has security risks. Roaming between access points
is particularly problematic. When users roam between access points, any solution
using advanced encryption technology may be broken.
