Types of VPNs and Protocols

Types of VPNs and Protocols

VPN service (Virtual Private network) provides a secure connection to the Internet via privately owned servers on a P2P basis. Devices are connected via a kind of tunnel, which encrypts data, and it passes through the tunnel without being detected by surveillance or governmental services. For this reason, VPNs are increasingly popular worldwide. There are two types of VPN services by connection:


  

1. Remote Access VPN

Also known as virtual private dial-up networks (VPDN), remote access VPN service provides safe and secure connections with remote private networks. This type of connection is popular both among business persons, employees and individuals, who use the Internet for their personal needs.

This kind of VPN service has two main components – a network access server (NAS), to which users connect, and client software, which is installed on users’ PCs and/or devices.

This software creates an encrypted channel and ensures safe and secure transfer of data. It enables employees to maintain contact with their companies while traveling and safely access corporate information, which should not be shared with any third parties. 

BroVPN does provide this kind of software and guarantees protection of corporate information. Also, it helps bypass restrictions and censorship and helps users access blocked websites.

  

2. Router – to – Router VPN

Router-to-Router (Site-to-Site) types of VPN services are better suited for corporate use, as they enable companies, whose offices are distributed around the globe, to safely connect to each other. In other words, one office can connect to the network of another one. This interconnection between different offices that are part of a single organization forms a so-called Intranet-based VPN network. An Extranet VPN network is formed when a company or a customer connects to another company’s office using a Router-to-Router VPN. This type of connection links companies and corporate divisions located far away from each other, and ensures maximally secure transfer of corporate data.

Site-to-Site connection is called “Router-to-Router’ because it uses two routers, one of which functions as a VPN Client, and the other one – as a VPN Server. To ensure connection, both sides should use the same software and carry out an authentication procedure. 

 

What VPN Protocols Does BroVPN Use?

 Both paid and free VPN services ensure encryption of data, which users share online. There are several types of VPN protocols that provide connection for different types of OS (Windows, Android, etc.) They have different security levels and protection patterns. So what about BroVPN protocols?

  

1. Internet Protocol Security or IPSec:

IPSec is compatible with all popular platforms and types of OS. The protocol authenticates sessions and directly encrypts data transferred during sessions. 

IPSec uses Transport and Tunneling modes. The former encrypts/authenticates the payload of the data packet, and the header remains unchanged. The Tunneling mode encrypts/authenticates the entire data load, including the header. This type of protocol is mostly used by many paid and free VPN services and can be combined with other VPN protocols for better protection.

 

2. OpenVPN

This VPN protocol is the most popular one among VPN providers and VPN users thanks to its simplicity and availability (it is open-source). It is great for setting up a Router-to-Router and Point-to-Point connections and compatible with a large number of platforms. OpenVPN uses SSL and TSL security protocols and therefore is good for online stores and banking institutions. 

  

3. IKEv2

This VPN protocol is commonly used in mobile devices. It is not actually a protocol, because it does not code data. IKEv2 can be used in combination with IPSec. It could be a great option for those who place speed of connection above online security.

 

4. SSTP

Although SSTP (Secure Socket Tunneling Protocol) was created by Microsoft and initially was not intended for use in VPNs, it is increasingly popular among both paid and free VPN services users. This is thanks to its high security level. The protocol uses the 443 port that circumvents almost all types of firewalls, and 256-bit AES encryption. It is ideal for Windows users, and it is also compatible with Linux, Mac and Android, with the use of respective client software.

 

5. PPTP

PPTP (Point-to-Point Tunneling Protocol) creates a secure encryption tunnel and thus protects data flows against attacks. The protocol has long been used by Windows, and today it is compatible with Mac and Linux and very popular among VPN users.  

 

These are protocols, which VPN providers and BroVPN use in an effort to ensure a quick and stable connection and a high data security level. Each protocol is great in its own way, so users are free to choose any type of paid or free VPN service and protocol to suit their individual and corporate needs.
