The rapid expansion of online retail has increased convenience for global consumers while simultaneously exposing retailers to sophisticated cybersecurity threats. As cyberattacks grow in frequency and complexity, incidents such as data breaches, payment fraud, account takeovers, and phishing have become primary obstacles that undermine consumer confidence. These threats compromise sensitive personal and financial information, creating heightened perceptions of risk and negatively influencing purchase intentions. Despite advancements in security technologies- such as encryption, tokenization, secure authentication, and web-application security many organizations continue to face vulnerabilities stemming from inadequate protective measures and weak governance practices. Regulatory frameworks, including GDPR and PCI DSS, attempt to strengthen data protection, yet compliance gaps persist in multiple regions. Trust remains a decisive factor in online purchasing behavior; therefore, transparent communication, rapid incident disclosure, and strong security assurances are essential for restoring post-incident confidence. This paper examines the major cybersecurity challenges in online retail and evaluates their direct and indirect impact on consumer trust. The study highlights the need for integrated technological, organizational, and regulatory strategies to enhance security resilience and sustain long-term customer trust in digital marketplaces.
