Virtual private network (VPN) technology has become increasingly important for ensuring online privacy and security. While premium VPN services offer the most robust features and performance, some users may not be willing to pay for a subscription. Fortunately, there are a number of free VPN services available, although these may come with certain limitations. In this article, we’ll take a look at some of the best free VPN services available, and the limitations that come with them.

1. ProtonVPN: ProtonVPN is a highly secure VPN service that offers a free version with limited features. The free version is supported by advertisements and can only be used on one device at a time. Additionally, it only allows access to servers in three countries.
2. Windscribe: Windscribe offers a free version that provides users with up to 10GB of data per month. It also has a feature called “R.O.B.E.R.T.” which blocks known malicious sites. However, the free version only allows access to servers in 10 countries and has limited features.
3. TunnelBear: TunnelBear is a user-friendly VPN service that offers a free version with a 500MB data limit per month. It has a strong focus on privacy and security and offers access to servers in over 20 countries. However, the free version does not allow users to access certain high-bandwidth services.
4. Hotspot Shield: Hotspot Shield offers a free version that provides users with access to servers in the US only. It also has a data limit of 500MB per day, which can quickly be used up by high-bandwidth services such as streaming video.
5. Speedify: Speedify is a unique VPN service that combines Wi-Fi and cellular data connections to provide faster speeds. The free version allows users to connect to servers in the US, Canada, and the Netherlands, but only provides 2GB of data per month.

While free VPN services can be useful for occasional use, they do come with certain limitations. These may include data limits, limited server locations, and reduced features. Additionally, free VPN services may not offer the same level of security and privacy as premium services, and may log user data. For users who require more robust protection, it is recommended to opt for a paid VPN service. However, for those who only need occasional access to restricted content, a free VPN service may be sufficient.
