Tips for choosing the free VPN

But after testing over 100 free VPNs, my team and I have found VPNs with strong security features to keep you safe. Some also have the added benefit of unlocking popular media streaming platforms. Unfortunately, they have all the limits. When choosing a free VPN, there are a few important things to pay attention to. My tests rated these best free VPNs using the following criteria:

• Truly Free – If a VPN is truly free, you don’t have to commit to a subscription. Plus, a truly free VPN doesn’t require you to provide payment information.
• Strong Security & Privacy – VPN requires industry-standard encryption, kill switch IP / DNS leak protection. Since you’ve checked all of the free VPN’s logging policies, nothing on this list stores logs that can identify and protect you.
• Good Speed ​​with Enough Data – A VPN should give you enough speed and enough data to browse the internet without sacrificing your speed. Also, look for free VPNs that offer lots of free servers. This is usually because it speeds up (because the server is not too crowded).
