There is no definite answer to it as it depends how far you want to go, how much you value your privacy, how well your device is secured, what virtual traces you normaly leave and many other factors. In these days, use of VPN is strongly recommended as it can protect you against basic virtual attacks. However, VPN will not help if you have your device full of viruses, malware and other threats that can capture what you are doing, or where you go. Cyber security is being underestimated and overlooked by many. It would be very smart for every individual using electronic device that connect to any virtual network to get better understanding to basics of cyber security.
