Block out access to azure resources from outside
I am looking for a way to completely block out access to azure resources from outside of Japan. An access from abroad is most likely from a person who are not from our company.
Recently, I am terribly worried because there are a lot of illegal access from the outside country. It's very reassuring to have the ability to shut off foreign access in Azure. This scenario is difficult to achieve because the NSG feature has a limit in a number of IP addresses which can be restricted.
Thank you for your suggestion. We are planning to offer more in the NSG space as well as DDoS solutions.
If you ONLY do business with companies in Japan, you could theoretically block ALL IP's which are not resident to the country of Japan.
