The nhs (my blog) is seen as a nice gravy train by firms like Oracle and Microsoft where there ‘products’ are not up to the job
Microsoft email is thoroughly shit there is the classic story of the large email list in the nhs that if anybody replies to all costs about £300,000.00 per email due to some ‘bug’ in exchange.
Ransomware is the latest find that exploits Microsoft failure to not defend against but since the exploit was known by both gchq and the nsa (my blog and not passed on you could argue that the government is ransoming itself by keeping mum.
I am not saying there is a perfect solution even assuming that this was not an inside job but it points the failure in any reasoning that Microsoft is enterprise software.
I am sure the management of the nhs would like that
