This is Part 2 of our VPN provider guide. Read Part 1 for information about protocols, IP protection, server networks, and zero-log policies.
Kill Switch
If your secure VPN connection gets interrupted, your computer reverts to your real IP address, which in turn compromises your identity. A kill switch prevents this by immediately disconnecting your internet connection as soon as the VPN connection drops.
This feature proves essential for:
- Maintaining anonymity during connection instability
- Preventing accidental data exposure
- Ensuring continuous protection without manual monitoring
- Protecting sensitive activities like financial transactions
Quality VPN providers offer configurable kill switches — some allow you to specify which applications should be blocked during VPN disconnection rather than cutting all internet access.
Mobile Device Compatibility
Activities on mobile devices can be risky when occurring on unsecured Wi-Fi networks. If you need more secure mobile operation, finding a provider that offers mobile VPN support becomes important.
Key mobile features to look for:
- IKEv2/IPSec protocol support — Excellent for roaming between networks
- Seamless network switching — Maintains connection when moving from Wi-Fi to cellular data
- Battery optimization — Minimal impact on device power consumption
- Native apps — Dedicated applications for iOS and Android
The ability to switch to IKEv2/IPSec protocol while roaming ensures your connection remains secure even when transitioning from public Wi-Fi to mobile data.
Authentication Options
When a computer attempts to connect to a VPN server, the VPN service must first authenticate the user before establishing the connection. Typically this means entering credentials on a login page or in a desktop client, but consider additional authentication options for enhanced security.
Multi-Factor Authentication
Multi-factor authentication requires you to authorize your login using a mobile device through an app. This adds a second verification layer beyond your password.
Physical Security Keys
You can also use a physical security key that plugs into a USB port for even greater security. These hardware tokens provide protection against phishing and credential theft that software-only solutions cannot match.
Customer Support
Like other software companies, a VPN provider should have reliable technical support that you can contact with any questions that arise. This support team should be:
- Knowledgeable — Understanding both basic and advanced VPN issues
- Helpful — Providing clear solutions rather than generic responses
- Accessible — Available through multiple channels (chat, email, phone)
- Responsive — Quick response times, especially for urgent issues
Look for providers offering 24/7 support, comprehensive knowledge bases, and setup guides for various devices and use cases.
Premium Pricing
As a general rule, it's best to avoid free VPNs. By choosing a paid provider, you're selecting a real, trustworthy company backed by quality technology and infrastructure.
Why free VPNs are risky:
- Often monetize by logging and selling user activity data
- May inject advertisements into your browsing
- Typically offer limited server options and slower speeds
- May lack important security features
- Could contain malware or security vulnerabilities
A paid provider is also less likely to log your activities and sell that information to advertisers. A premium VPN service may require monthly payment, but the value of security, reliability, and peace of mind is worth the investment.
