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.
The solution is also able to bypass firewalls through stealth connections. Additional security is provided through an ad and malware blocker, which can be switched on and off. For those who enjoy torrenting, the software supports such process, with certain servers optimized for P2P networks. This is designed to keep high-speed browsing on other connections. However, the service warns users to keep torrenting activities confined to specific cities around the world.
They even offer the most generous simultaneous connection count, with six simultaneous connections through their network, where everyone else offers five or fewer. NordVPN's network isn't as large as some of their competitors, so if you're trying to obfuscate your tracks, you might want a company with more servers. Otherwise, this company is clearly providing a winning offering.
