Demystifying VPNs: Your First Line of Digital Defense
A Virtual Private Network (VPN) creates an encrypted tunnel between your device and the internet, shielding your online activities even on public Wi-Fi. According to Cybersecurity & Infrastructure Security Agency guidelines, VPNs are fundamental security tools for all internet users. They prevent ISP tracking, conceal your IP address, and secure sensitive data.
Choosing a Trustworthy VPN Service
Not all VPNs offer equal protection. Prioritize services with:
- Strict no-logs policies (independently audited)
- AES-256 encryption - the military-grade standard
- Kill switch functionality to prevent data leaks
- Global server coverage for reliable connections
Avoid free VPN services that may sell your browsing data or lack essential security features.
