The internet basically runs our lives nowadays. The internet offers information, entertainment, news, social connections and answers in a split seconds. It can be accessed from anywhere and on any compatible device. It allows organizations to reach target markets as well individuals and students attend online classes.


But in as much as the internet is important, it has its own downsides and vulnerabilities. There are always data security threats lurking around on the internet. It is because of these threats that a Virtual Private Network (VPN) comes in handy.




A VPN is a tool that is used to protect you, your devices and your data from threats and vulnerabilities on networks. The networks in this case are mostly public and may include a public network, Wi-Fi and the internet. The tools are also used in the business and corporate sector to offer protection to sensitive information. There has been a rise in demand of VPNs which means that people are beginning to take their data security and privacy seriously. Personal VPN’s popularity has grown exponentially.


Security


The whole concept of a VPN is based on the privacy and security of your data and device. It might not protect you against malware but it guaranteed to protect your browsing sessions by letting you browse anonymously. Security is the only major reason that explains why the business and the corporate sector has been using VPN services for a long time. There are emerging ways in which hackers can intercept your data while transmitting it on a network. The simple framework in this case is that a Firewall safeguards your data while it is still on the computer but a VPN is required to protect your data during transmission on a network.


A VPN tool utilizes sophisticated security protocols to encrypt and find a secure tunneling technique to transmit data online. This prevents hackers and other individuals with malicious intent don’t hijack and intercept your data. This process involves the user signing in to a public network using an ISP (internet service provider) protocol which then initiates a VPN connection via the VPN service provider.


There are various security protocols utilized by VPNs on the market today. It is important to find out the type of security protocol offered by a VPN service before purchasing it. This is because different levels of security protocols offer varying security and features. They include.


·         IP security- abbreviated as IPsec, this protocol is usually used to secure data transmission on the internet. It operates in two modes. The transport mode involves encryption of data packet content only while the tunneling mode involves the encryption of the data packet in entirety. It can be used alongside other security protocols.


·         Layer 2 Tunneling Protocol (L2TP)/IPsec- this protocols merges the functionalities and features of L2TP and IPsec security protocols to give you a high performance VPN. In this case L2TP generates data tunneling while IPsec generates encryption of the data packet.


·         Secure Socket Layer (SSL) and Transport Layer Security (TLS) - this is a very powerful combination of security layers, it provides robust security and sophisticated encryption. The security layer creates secure connections between your device and the network without a hassle.


Why you need a VPN


There are various compelling reasons as to why you should use VPN services.


i)        Secure messaging- not all online messaging platforms use encryption while sending out messages or mails. Utilizing a VPN tool during messaging services offers you with a higher level of security.


ii)       VoIP- it is an abbreviation for Voice over Internet Protocol. This an advanced technology that allows you to send digital messages at a considerably lower cost. The only problems is that these voice messages can be intercepted over a network. Sending your voice communication via a VPN makes it secure by encrypting it before sending.


iii)     Bypassing government censorship and restriction- in countries where the internet is highly controlled by the government, a VPN can come in handy.


iv)     Secure public Wi-Fi connection- public Wi-Fi can be a package of threats. They include data phishing programs, packet sniffers and spyware which can facilitate hacking or malware infection on your device. A VPN comes in handy in these situations to protect you against such attacks.
