You can find more information below on these VPN protocols. All of these protocols are considered highly secure by the infosec community. TunnelBear uses OpenVPN/IKEv2 on Windows, OpenVPN on MacOS and Android, and IPSec/IKEv2 protocols on iOS. The degree of security a VPN has depends on the protocol chosen. Internet protocols determine how data packets are sent across a network. TunnelBear uses 2048-bit DH for Windows, 3072-bit DH for MacOS and iOS, and 4096-bit for Android. The higher the number of bits, the more secure the key exchange. The Diffie–Hellman (DH) key exchange is a way of sending cryptographic keys over a public channel. Diffie-Hellman Exchange Diffie-Hellman Key Exchange SHA256 is 256-bit SHA and is considered secure by the information security (infosec) community. This is done rather than sending sensitive information in plain text across the internet. SHA, or Secure Hash Algorithm, creates a “hash” of unique characters that can be compared to authenticate passwords or keys. The United States uses AES-256 to encrypt top-secret information, which is why sometimes you will see this advertised as “military-grade encryption”. AES-256, AES with a 256-bit key, is ubiquitous in the encryption field because it’s fast, secure, and doesn’t use much computing power. AES-256Īdvanced Encryption Standard (AES) is an encryption algorithm used to encrypt data with a 128-, 192-, or 256-bit key lengths. Here’s a brief summary of this technical jargon means. TunnelBear uses AES-256 for data encryption, SHA256 for data authentication, and 2048-, 3072-, or 4096-bit DH group for handshake encryption. At least I would hope so! If you can’t trust the encryption of your VPN, then it’d be better to stick with your regular ISP. With all your data being transported through that shiny, new VPN tunnel, you might be wondering how secure that tunnel is. TunnelBear Encryption How Encryption Works With that said, if you’re going to be torrenting often, I would recommend a VPN that has servers designed for P2P file transfers, like FastestVPN. TunnelBear used to block access to P2P downloads, but now torrenting does seem to work on TunnelBear. In the past, the answer would have been no. What I mean is that in the tests I performed in the United States and European Union servers, TunnelBear doesn’t work with Netflix. TunnelBear fight, Netflix is currently on top. The battle between Netflix and VPNs has been raging for years now. TunnelBear does have split tunneling, but only on Android. For example, this feature would let you watch Netflix through your ISP unencumbered, while you are surfing the web with your VPN at the same time.
Split tunneling is a feature allows you to route some web traffic to your Internet Service Provider (ISP) and some through an encrypted VPN tunnel. Does TunnelBear Offer Split Tunneling? Split Tunneling Luckily, TunnelBear does have a kill switch, called VigilantBear, on Windows, Mac, and Android. Without a kill switch, a momentary outage could expose your private IP address.
TUNNELBEAR FREE VPN FOR MAC SKIN
This feature could save your skin if you’re a journalist or downloading a torrent that might be copyrighted content.
TUNNELBEAR FREE VPN FOR MAC WINDOWS
Screenshot from TunnelBear Windows app.Ī kill switch, also known as a network lock feature, is an application feature that “kills” your internet if your VPN connection is lost. Does TunnelBear Have A Kill Switch? TunnelBear Kill Switch. The point is, TunnelBear will never log your web traffic, which is the purpose of having a VPN in the first place. You can decide whether this information is too much for you.
