PIA does offer a Chrome browser extension, but it’s only a proxy. It gives you a certain degree of privacy by changing your virtual location, but it doesn’t offer encryption like the full VPN app does. So, in situations when strong security is most needed (such as online banking), I recommend using the PIA’s full VPN app. This protects your entire device, including your browsing sessions. Aside from Chrome, PIA browser extensions are also available for Firefox and Opera.
