Most people ask ‘why I should use a VPN, what it is and how it helps’? Well, VPN or Virtual Private Network is a form of network that has been carefully designed to offer a secure conduit when it comes to data transmission amid a web browser and a web server. This tunnel is secure owing to the encryption levels thereof. In today’s age, VPNs have turned into a mandate exclusively for their efficiency and practicality.
How can a Suitable VPN Help?
If you have a VPN that is suitable, you can enjoy the following,
- Privacy- VPN will enable you to stay anonymous when you are online. Be rest assured that neither the government nor your ISP can see your activities online.
- Censorship- Most institutions like the workplace, schools, the government, and your ISP as well can censor any activity that you perform online. With a good VPN, you will be capable of evading all that along with possessing the freedom that you want no matter the network type.
- Geo Spoofing- Often users are denied some online services online based on the geographical location. A VPN will be an ideal means of overcoming such restrictions because it will mask your location providing you with the access that you require.
- Prevent Hackers- We time and again hear not to use our devices on a public wi-fi hotspot. That is because it will make you fall prey to malicious people and hackers whose intention is in stealing your data. An ideal VPN can solve this issue via offering you with the right encryption for staying safe from such hackers.
- Downloading- If you love to download files online be it software, movie or songs, having a secure connection is a must because this will help in preventing an attack and keeping all your identity anonymous. To learn more visit FastestVPNGuide.com
Broad Categorization
To have a proper understanding of a VPN, it is essential to be familiar with the different forms of VPNs available. VPNs are of two broad categories – Site-to-Site VPN and Remote Access VPN.
- Site-to-Site VPN- The site-to-site or router-to-router VPN is extremely popular with corporates. Mostly, businesses which have offices in different geographical locations use this. The VPN acts as a safe virtual bridge. Here the geographically distant workstations’ networks are joined for maintaining secure communications.
- Remote Access VPN- The VPN is for connecting to private networks. One can use its resources from a remote location with its connection through the public internet yet is secure and private. The remote access VPN is equally beneficial for business and home users alike. If you are an employee who wishes to work while traveling, you will require a VPN for accessing the vital resources or files you need from the organization’s private network. On the other hand, this VPN for a home userwill prove handy for bypassing the restrictions like blocked sites.
The Powerful VPN Protocols
The VPN security protocols are available in various types which offer security features of varying levels. Take a look,
- IPsec or the Internet Protocol Security- Through this protocol one can have secure online security communication all over an IP network. It will secure the communication via authenticating as well as encrypting every data packet at the time of the connection. IPsec functions in two modes namely tunneling and transport. The former will encrypt the whole data packet, and the latter will handle the message encryption within the data packet. This VPN protocol is also used together with different other security protocols for enhancing the security system.
- PPTP or Point-to-Point Tunnelling- This protocol helps in creating a tunnel as well as encapsulate the data packet. The point-to-point tunneling will pave the way for multiprotocol traffic encryption and encapsulate within the IP header for being sent across online. The primary use is for site-to-site and remote access connections.
- L2TP or Layer 2 Tunnelling Protocol- This protocol will merge with other security protocols like IPsec for attaining a highly secure VPN connection. It is accountable to create a tunnel amid 2 L2TP connection points, and the IPsec protocol will take care of the data encryption and the secure communications amid the tunnels.
- SSL or Secure Socket Layer and TLS or Transport Layer Security-Both online shopping sites and online service providers use these protocols commonly. They will help in creating a VPN connection that will help the web browser is acting as a client thereby restricting the access to the user to specific applications and not to the network in its entirety. A web browser has the flexibility of swiftly switching to the SSL because it comes integrated with TLS and SSL. The former can be identified easily through https at the URL’s beginning rather than HTTP.
- SSH or Secure Shell- It will help in creating the VPN tunnel into which the transfer of data will take place and at the same time ensure the tunnel’s encryption. The SSH clients will make SSH connections while the data will be routed towards the remote server from the local port through the encrypted tunnel. This protocol is ideal to offer an encrypted channel for allowing the logging into a different PC over a network along with shifting files from a particular PC to another. It will provide secure authentication and encrypted communication.
- OpenVPN- This protocol is flexible software that is open source and a tunneling application that uses TLS/SSL for crucial exchange along with being capable of traversing NATs (Network address translators) and firewalls. The Open VPN will make sure connections of point-to-point are in routed configurations. It is both stable and also reliable on unreliable networks and Wi-Fi hotspots. That will offer high speed on connections that have latency that is excessively high.
- SSTP or Secure Socket Tunnelling Protocol- This VPN tunnel will allow in the PPT traffic’s transportation through a TLS/SSL channel. It is mostly used in case of remote client access and supports user authentication.
Using a VPN service is safe and legal and will ensure that every person’s online activities remain private. After learning about the significance of using a VPN choosing it right also matters. After all, it is critical when it comes to your anonymity and online security. Some pointers that you need to consider here include- the protocols it uses, the number of servers as well as server locations that it offers, will it log the activities that you do online, its spyware/anti-malware capabilities, contains mobile apps, the pricing, internet speed, and customer support.
