One NoodleVPN account affords you the ability to connect up to 6 devices simultaneously.

Since every computer on a network is assigned with an IP address to retrieve information, all activity performed online has an IP signature. Just like your Internet Service Provider (ISP), every webpage tracks the IP addresses of their visitors to collect user-oriented data, and this is done without the agreement of the visitors.

All kinds of user identification can be collected by tracking IP addresses. For example, a website can gather information such as user’s ISP, actual location and other data that can be stored and used at the discretion of the website owners.

At present, search engine giants such as Google use IP addresses as well to associate a search pattern and online activity with every single user. This is done to deliver more targeted ads, but with the kind of information that is being collected, it is worrying to note that Google is in a position to profile Internet users quite accurately.

Socket secure (or “SOCKS”) is a protocol for handling TCP traffic through a proxy server. SOCKS Version 5 adds additional support for security and UDP. SOCKS proxies do not interpret network traffic, which means they are not able to understand what is being passed from the client to the server and vice versa, and that makes the connection secure.

SOCKS uses a handshake protocol to inform the proxy software about the connection that the client is trying to make. It’s capable of transferring all information from a client to a server even through firewalls because the web server views the SOCKS proxy as the client.

OpenVPN is an open source software application that executes virtual private network (VPN) techniques for producing safe site-to-site or point-to-point connections in remote access facilities and bridged or routed configurations. OpenVPN uses a custom security protocol which utilizes TLS/SSL for key exchange. It is able to traverse firewalls and network address translators (NATs).

OpenVPN allows peers to authenticate each other using username and password, certificates, or a pre-shared secret key. When used in a multi-client server configuration, it allows the server to launch an authentication certificate for every user using certificate authority and signature. It uses the OpenSSL encryption library broadly as well as TLSv1.2/SSLv3 protocols and consists of many control and security features.

IKEv2 is a state-of-the-art protocol option, which combines speed with stability and security. A unique aspect of IKEv2 lies in its ability to hop between connections. For example, it can automatically jump from WiFi to a cell network without losing or dropping the secure VPN connection. When combined with Internet Protocol Security (IPsec), it significantly increases security and privacy of the user by employing very strong cryptographic algorithms and keys.

NordVPN uses NGE (Next Generation Encryption) in IKEv2/IPsec. The ciphers used to generate Phase1 keys are AES-256-GCM for encryption, coupled with SHA2-384 to ensure integrity, combined with PFS (Perfect Forward Secrecy) using 3072-bit Diffie Hellmann keys. IPsec then secures the tunnel between the client and server using the strong AES256.
