The four challenges involved with international networks are service quality, security, costs, and regulatory constraints. Firstly, regarding the service quality, one should note that aspects such as speed and reliability of network access provided by public organisations are questionable. Hence, organisations should be cautious of the regional differences that limit the access and quality of the public networks. Next, security and use of authentication is an essential problem due to cases of hacking and unlawful use of private data. For this reason, private networks are often used instead of public ones to ensure that information exchange is secure. In this regard, the companies should pay additional attention to ensuring that their international networks are secure because the loss of data would affect all subsidiaries.
Next, the problem of cost is substantial since although in European countries, access to public networks is available to the majority of populations through high-quality services, this is not the case for many developing countries. Next, regulations are the most challenging and difficult to address the problem of international networks. For example, China has blocked popular social platforms and websites, meaning that companies cannot rely on some services in their work. While in some cases, this issue can be mitigated by applying a VPN, the fact that these regulatory constraints exist make it difficult for some businesses to operate since it highlights a possible threat. In general, companies can address some of these issues, for example, by training their employees to be able to understand the technology and gain necessary skills. These four challenges encompass the main problems that businesses encounter when developing international networks.
