Recently it has been announced that the most popular browsers, such as Safari, Chrome, Mozilla and Microsoft Edge, will not allow unsafe connections through the use of both SSL and TLS insecure versions protocols after 2020. This action will result that services that have implemented with these old protocol versions will stop working.
Microsoft recently posted their statistics on the current situation of most sites. As you can see in the following image, 94% of the sites are already compatible with TLS version 1.2 and less than 1% still are using TLS version 1.0 or 1.1.
The organisations that have not yet completed the protocol migration will experience a negative impact on their business if they do not take the appropriate measures on time, especially if the business must comply with PCI DSS.
