Firstly, they can come with hidden costs – you might get ads injected into your browser or, even worse, end up having your data sold or your device used as an exit node for other users. If you're going to get a free VPN, you need to know the facts. While it's unlikely they'll be getting you access to worldwide Netflix libraries, they can work in a pinch if you want to securely access your email on public Wi-Fi, or do a search you'd rather no one find out about. You won't be surprised to hear that no free VPN can match the very best VPN services, but for casual users they can be a useful tool to have at your disposal. Knowing how providers can afford to offer a free service in the first place and what sacrifices you'll have to make in terms of functionality and privacy is essential, and will certainly factor into your decision.
It's important to understand how a free VPN works before entrusting it with your online activity. However, is that what you can realistically expect?
A free VPN sounds like the perfect solution – total anonymity online, unblocked streaming sites and the freedom to browse what you want without the fear of being tracked, all without spending a penny.
