Encryption Standards
Robust encryption is the foundation of any VPN. Look for services that support AES-256 encryption, which is the industry standard for securing data against brute-force attacks. Additionally, verify which protocols the provider supports. Protocols like WireGuard and OpenVPN are widely regarded as the best balance between high-speed performance and high-level security.
No-Logs Policy
A "no-logs" policy means the provider does not keep records of your browsing history, connection timestamps, or IP addresses. It is critical to choose providers that have undergone third-party audits to verify these claims, as a VPN is only as private as the company's commitment to data minimization.
Kill Switch
A kill switch is a security feature that automatically disconnects your device from the internet if the VPN connection drops unexpectedly. This prevents your unencrypted traffic from being exposed to your ISP or other observers during the outage.
Server Network and Distribution
The number and location of servers impact both connection speed and the ability to bypass geo-restrictions. For US users, having a broad selection of servers across domestic cities can significantly improve latency and throughput.
