Whilst your internal systems and servers may be secure from malicious attack, the website is often an area which can be overlooked. As Marketing teams require more ability to gather valuable customer data and insight, the usage of third-party technologies on site will increase - thus the risk of data leakage will rise.
Cybercriminals are constantly developing more sophisticated methods to target areas of vulnerability. Magecart and other cybercrime groups continue to exploit trusted third-party suppliers operating on site, to steal customer data, a method also known a digital payment skimming. This vulnerable area is often overlooked - in 2018 alone, there were over 300,000 Magecart data breaches.
