I'm sorry if I gave the impression of saying that all NoSQL products are insecure, or even that it is a general case. NoSQL is a very broad marketing category for a diverse range of products. The article I quoted at the start had a rather provocative title, but only evaluated two products, and gave, by implication, the idea that this was a general case. Some 'NoSQL' products have full transactionality and some have a high standard of security.

What I was trying to say was that, if you are having to select a database for a particular use, it would be wise to check that it actually has those features of security and data integrity that are important for the company you work for, or the users of your application. You can't just assume that they are there. There has been no technical breakthrough to doing all that hard boring stuff
