If you ever connect to public WiFi or just value your privacy, using a VPN is essential. With blazing fast connections and servers spread around the globe, PureVPN is one of the best options around. You can get a lifetime subscription for $36 (Orig. $597) via 9to5Toys Specials with coupon code “GREEN40.”

Billed as the world’s fastest VPN, this service helps you enjoy the web without revealing your browsing history. With over 550 servers in 141 countries, PureVPN disguises both your IP address and physical location. This makes it impossible for anyone to track your connection, including your ISP.

In addition, you can protect your data using AES-256 encryption. This is vital if you regularly use hotel WiFi, as these networks are often insecure.

With apps for all major desktop and mobile platforms, PureVPN provides instant protection. You can also use the service on smart TVs, games consoles, and other devices. This means you can avoid regional restrictions on sites like Hulu and Netflix, with unlimited bandwidth for all your streaming needs.
