Do you need a VPN? If youre looking at any VPN service this question should be one of several at the forefront. Is signing up to this service the best solution to the privacy challenge you face? A virtual private network (VPN) can help to protect your privacy, defend against electronic surveillance, and protect your device from intrusion. But its not a complete solution itself. Other strategies, such as improving your security practices (for example, stringent passwords, personal data encryption), should take priority over VPNs.
