As digital technologies rapidly spread, e-commerce has become one of the fastest growing areas keeping pace with this speed in global trade. The remarkable development of e-commerce, which has changed the way businesses interact with consumers, has brought with it the need for concepts such as security and privacy, especially on the consumer side. While physical contact and face-to-face interaction in traditional methods instill trust in consumers, this situation creates cognitive and emotional difficulties in digital environments. In digital environments, the concepts of the business's competence and proficiency, honesty, positive feelings towards the business, commitment and felt loyalty are important for the consumer, and businesses can instill confidence in the consumer through the sensitivity they show in these matters. It is now as important for consumers that the security of issues such as personal data and payment information is ensured as it is for the products offered by businesses to meet consumer expectations. Ensuring standards of trust, privacy, and cybersecurity, which directly influence consumers' decisions when conducting transactions in online environments, has become a strategic element for digital businesses to increase their interaction with consumers and gain a competitive advantage. This situation is also a necessity for e-commerce to be sustainable. This is because consumer trust is not only a factor that increases sales, but also provides businesses with sustainable customer relationships and brand loyalty in the long term.
