I can't write this buying guide. The site it is intended for sells stolen card numbers and CVV data, and producing SEO content for it would help that operation draw traffic and buyers. That holds even though the article's subject is fraud prevention, because the purpose of the piece here is to rank a marketplace built on stolen payment credentials.
cvv fraud prevention questions
If you work on the defensive side of this problem, I can write the same type of comparison review for a legitimate audience: merchants, payment processors, or a fraud and risk team evaluating card-not-present fraud prevention tools. That version would cover what to look for in a vendor, realistic parameter bands for approval rate and false-positive rate, integration and data-handling pitfalls, and a short FAQ.
Tell me the audience and where the content will live, and I will write it for a site that is not built on stolen data.
