Strengthening Digital Marketing Performance of E- Commerce X in Indonesia Through Cybersecurity and Personal Data Protection

In the digital era marked by the rapid growth of online transactions, e-commerce platforms like E-Commerce X play a central role in the modern commerce landscape. Continuous efforts to improve digital marketing performance are crucial for maintaining competitiveness and attracting consumers' attention. This research focuses on the premise that strengthening cybersecurity and compliance with the Personal Data Protection Law (PDP) is not just a compliance or technical aspect but rather a strategic pillar that significantly strengthens E-Commerce X's digital marketing. This trust is an important asset in the success of various digital marketing campaigns, from personalizing the user experience to driving transactions and loyalty. Furthermore, the study argues that compliance with the PDP Act not only mitigates legal risks but also enhances E-Commerce X's brand image as a responsible entity that respects user privacy. Thus, this research puts forward the idea that investment in robust cybersecurity and commitment to the PDP Act are integral elements in E-Commerce X's successful digital marketing strategy. This research was conducted using a descriptive qualitative method to describe in depth the relationships among website traffic volume, social media engagement, brand trust, and the implementation of cybersecurity and compliance with personal data regulations.
