No reputable VPN service logs any kind of user activity, unlike your internet service provider, which can easily log every website you visit by storing all your DNS requests sent in cleartext. The only VPN on this list that maintains 24 hours worth of basic connection logs (no activity) is VPN.ac, and they clearly state their reasons (security) for doing so. There have been shady VPNs that have cooperated with government agencies, such as PureVPN (see logging case) and I do not recommend these providers.
Obfuscation – Obfuscation is a key feature if you are using a VPN in China, schools, work networks, or anywhere that VPNs may be blocked. However, if you are not in a restricted network situation, obfuscation is generally not necessary and may impact performance. (See the best VPN for China guide for a great selection of VPNs with built-in obfuscation features.)
NordVPN has a lot of excellent feature members love. For example, you get top of the line security features from this company including a kill switch that automatically shuts down your session when the connection is not secure. You can choose between a single app kill switch or a full system kill switch, too. NordVPN also offers IP hiding, so your identity is safe with them. Don’t forget the double VPN servers that encrypt your data twice for added security.
Using a VPN will prevent most kinds of DNS attacks that would redirect you to a phishing page, but a regular old page made to look like a legit one in order to trick you into entering your data can still work. Some VPNs, and most browsers, are pretty good about blocking phishing pages, but this attack still claims too many victims to be ignored. Use common sense and be sure to verify that websites are what they say they are by looking carefully at the URL and always visiting HTTPS sites.
Routers – When you install the VPN on your router, all the devices that connect to your router will be using the encrypted VPN tunnel – without the need to install VPN software on each device. The router will only count as one VPN connection under your subscription, even if there are numerous devices using the router’s encrypted VPN connection. There are some important considerations before you do this – see my popular VPN router guide for setup tips.
