What are the disadvantages of a private network?

Private networks can be more expensive to set up and maintain than public networks.  Additionally, because access is restricted, it may be more difficult to collaborate with external partners or vendors. Private networks also rely on physical infrastructure, such as cables and routers, which can be vulnerable to damage or failure. This can result in downtime and lost productivity if the network is not properly maintained or backed up. They can also be difficult to scale up or down as the needs of the business change. Adding or removing users, devices, or resources can be time-consuming and require additional hardware and software investments.

Overall, businesses and organizations need to carefully consider the advantages and disadvantages of private networks before deciding whether they are the right choice for their needs. While private networks can provide increased security, control, and performance, they also require significant investment and ongoing management to ensure reliability and scalability.
