3. Types Of VPN -:

Now There are Three Types of VPN. These are given below -:

• Site-to-Site VPN
• Remote Access VPN
• VPN as a Service

3i. Site-to-Site VPN

A Site-to-Site VPN Connects two different geographically websites. Nowadays, the majority of security gates come with VPN connectivity. A next-generation firewall (NGFW), for instance, implemented at the network's perimeter safeguards the business network and simultaneously acts as a VPN gateway. This gateway, which encrypts the traffic supplied to the gateway at the other site, handles all traffic that travels between the two sites. The data is decrypted and sent to its destination through this gateway.

3ii. Remote Access VPN

A secure connection between distant users and a business network is made possible by a remote access VPN. For instance, many firms made the switch to a remote workforce in the wake of the COVID-19 pandemic in 2020, and they set up secure remote access VPNs from the distant clients to connect to crucial business processes at the corporate site.

3iii. VPN as a Service

VPN as a Service, often known as a cloud VPN, is a VPN that is hosted on a cloud-based infrastructure and uses that cloud infrastructure as the point of entry to the Internet rather than the local address of the client. This concept is frequently used by consumer VPNs, giving customers the ability to protect themselves while connecting to the Internet over unsafe public Wi-Fi and offer some privacy while doing so.

4. No bandwidth throttling -: When its clients access particular websites or utilize particular services, some ISPs place bandwidth restrictions on them.

5. Protects us while working Remotely -: With more individuals than ever working remotely in the wake of the COVID-19 outbreak, a VPN is particularly important for enterprises and corporations. Accessing business networks remotely puts confidential consumer and corporate data at danger of theft.

Working remotely on a public or shared network puts your sensitive information at risk of exposure to hackers since someone on the same network with the correct credentials might access internal corporate systems.

Access to firm information by unauthorized third parties can have catastrophic effects on a corporation. In order to ensure that all sensitive data is protected, it is crucial for businesses to move towards a safer remote work environment and implement VPN technology.

5. Doesn't Work with some devices -: There are certain exceptions to the rule, particularly when it comes to smart home gadgets, even if the majority of common devices and operating systems are fully compatible with VPNs.
