Abstract
A Virtual Private Network (VPN) is a technology that enhances online privacy and security by establishing a secure, encrypted connection between a user's device and a remote server. Acting as a protective tunnel, a VPN routes the user's internet traffic through this encrypted connection, shielding their data from potential cyber threats, surveillance, and unauthorized access. VPNs serve as powerful tools for safeguarding sensitive information, especially when using public Wi-Fi networks, as they prevent hackers or malicious entities from intercepting data transmissions. Additionally, VPNs allow users to mask their true IP address with that of the remote server, effectively anonymizing their online activities and bypassing geographical restrictions. Beyond security and anonymity, VPNs offer other practical benefits. They enable users to access region-restricted content, granting access to websites, services, and streaming platforms that might otherwise be unavailable in their location. Whether for personal use or business needs, VPNs have become integral in today's digital landscape, providing a reliable means of maintaining privacy, evading censorship, and fortifying online experiences.The significance of researching Virtual Private Networks (VPNs) lies in their pivotal role in modern cybersecurity and digital privacy. As online threats and data breaches continue to escalate, understanding the intricacies of VPN technology is crucial for developing advanced encryption techniques, improving network security protocols, and countering emerging cyber risks. Furthermore, VPN research contributes to enhancing user awareness about the importance of safeguarding personal information, aiding in the design of more effective privacy solutions for individuals, businesses, and organizations. By delving into VPNs, researchers can devise strategies to mitigate cyber threats and ensure a safer online environment for users worldwide.The DEMATEL (Decision-Making Trial and Evaluation Laboratory) method is a systematic approach used for analyzing complex interrelationships among various factors in a decision-making process. By visually mapping cause-and-effect relationships, DEMATEL helps to identify key drivers and dependencies within a system. It quantifies the strength and direction of these relationships, enabling decision-makers to prioritize factors based on their impact. This method finds applications in diverse fields such as business, engineering, healthcare, and environmental management, aiding in understanding intricate systems, formulating effective strategies, and making informed decisions in complex environments.ExpressVPN, NordVPN, CyberGhost VPN, Private Internet Access, Surfshark.
