Learn About Various Types Of Virtual Private Networks for your Mac


Nowadays, you can see businesses increasingly installing a virtual private network on their official workplace OS X devices. The immense benefits offered by this technology makes it a must-have software for any business. A VPN (virtual private network) is used to access a geographically restricted content, explore websites without any limits, and safeguard your business or the personal data of your MacBook hard drive from getting exposed on the internet. This is why VPN aids in boosting the overall internet experience of users.

What is VPN?

VPNs or Virtual Private Networks enable users to safely access a private network and distribute data remotely via public networks. A VPN for Mac works much like a firewall that safeguards data stored on your computer. VPNs do the same task online.

How does VPN work?

VPNs are immensely popular among corporations for securing sensitive data while connecting to remote data centers. Building secure connections is one of the main objectives of using a VPN for a business. This method makes it very easy and safe for employees to log into a private corporate business network from remote locations via their Macs.

VPN technology uses a combination of encryption protocols and dedicated connections to generate virtual point to point connections. This network enables individuals to hide their physical location. This is done by replacing your actual IP address with the VPN service provider’s, thus enabling it to bypass content filters.

Different types of VPN security protocols

Many security protocols are build because VPNs offer varying levels of features and security. Most common ones being:

IP security:

IPSec is used to protect online communications of a business. It can operate in 2 modes. Transport mode and Tunneling mode. The transport mode only provides encryption for the data packet message that is being sent from your Mac, while tunneling mode encrypts the entire data packet.

Layer 2 Tunneling Protocol and IPsec:

Both of these protocols come up with their best individual features to develop a highly safe OS X VPN client. L2TP protocol does not do any encryption, it only creates a tunnel. IPSec protocol deals with encryption, data integrity, and channel security to make sure that all packets arrive in order and that the integrity of the channel will not be compromised in any way.

Secure Sockets Layer protocol and Transport Layer Security protocol:

Both SSL and TLS protocol is extensively used in ensuring the security of e-service providers and retailers.

Point-to-Point Tunneling Protocol

PPTP is a universal virtual private network protocol that does not perform any encryption on its own. It only tunnels and captures the data packet. A secondary protocol that is called TCP is required to handle the encryption.

Secure Shell:

This protocol creates VPN tunnel as well as encrypts the data. It enables users to send information by directing traffic from remotely located fileservers via an encrypted channel. The data is not encrypted but the tunnel through which it moves is encrypted.


Installing a VPN on your Mac is the best answer when you’re accessing data remotely from an unsecured public network. This service helps in protecting critical and sensitive business information from getting into the hands of wrong people. Thus, a simple VPN installation on your OS X  Apple device will be the best way for you to prevent risking your business or your personal private data.
