How to stay safe on the internet using VPN & Antivirus program?

You've heard this advice before: whether you're in the office or on the street, a VPN is one of the most effective ways to secure yourself online. But how effective are VPNs? What is perfect for you? What are the disadvantages? WHAT IS A VPN? VPN is short for Virtual Private Network. The goal of the VPN is to ensure security and privacy when communicating over the Internet.

Here is the problem with the Internet: it is insecure by nature. When the Internet was first designed, the priority was to send packages as faithfully as possible. Networks across the country and around the world were relatively new, and nodes often failed. Most of the basic Internet protocols are designed to bypass failures rather than protect data.

Although some standards have risen, not all internet applications are protected. Many still send their advice without any privacy or security protection.

This exposes every Internet user to criminals who may steal bank details or credit cards, governments who may want to eavesdrop on their citizens, and other network users who may want to spy on you for many different evil reasons. The point is, everything you send is encapsulated in this personal communication channel and coded, so - even if your packets are intercepted - they cannot be decrypted. VPNs are extremely effective and important tools to protect you and your data, but they have limitations.


Let's start with the basic idea of ​​internet communication. Suppose you are at a desk and you want to access a website. To this end, the computer begins the petition by sending any packages.

If you are in the workplace, these packages often travel through routers and switches on your LAN before being transferred to the public Internet through a router. After traveling through the public Internet, these packages travel through many computers. A separate petition has been submitted to a collection of name servers to translate the DNS name to an IP address. This information is delivered back to the browser, which then sends a request via several computers on the public network. Finally, it reaches the website infrastructure, which similarly tracks these packages, and then captures the website (which will be a bundle of separate elements) and sends it all back to you.

Type of VPNs

Each online request usually results in an entire collection of communication events between multiple points. The way VPN works are to pay attention to these programs at their starting point, often hiding not only data but also information about the initial IP address. The VPN software at your end sends these packets to the VPN server at a certain destination, decrypting this advice. One of the most important problems in understanding VPN restrictions is understanding where the VPN server endpoint is.

We will discuss this later. This is the private interior of the network of one physical place - make it a home, business building or campus. But many companies do not operate from one location. They have branches, branches, and branches that are geographically dispersed.

In many cases, each of these branches also has LANs. But how to join a LAN? For some truly specialized solutions, companies rent private lines to join offices. It can be very expensive. Instead, most companies choose to connect separate private LANs over the public Internet. To protect their information, they set up VPNs between offices, encrypting data when browsing the public network. It can be a corporate or venture VPN and has the same company that controls the VPN endpoints.

If your company controls the start point (say, revenue sharing) along with the endpoint (such as the VPN server at the company's headquarters), you can be pretty sure (unless an error occurs) that your information is sent securely. VPN type is a VPN client.

It is for those of you who use a computer in hotels or cafes and connect to internet applications such as social networks, e-mail, banks or shops. Private VPN providers help protect this communication.


The VPN service provides a secure tunnel between your computer device and the support information center. It is very important to understand this. VPN consumer services protect your transmission from place to place, not from the destination to the destination program being used. If you take this into account, it makes sense: the VPN service for consumers is operated by a completely different company than, for example, Facebook or own bank.

Now the data is decrypted and sent along the way. There are two things here: first, if you use an https connection, your data is encrypted by the browser and then from the VPN application.

In the VPN data center, your data is decrypted only once, leaving the encryption provided by the browser intact. This encrypted information is then passed to a target program such as your bank.

The second thing that happens is that the web application you are talking to does not see your IP address. This gives a certain amount of anonymous media. This IP spoofing can be used to trick applications into thinking that you are in a different region or country other than your country. There are reasons for this (both legal and illegal). We'll talk about this in a moment.


We have already discussed the use of a VPN when connecting offices. Whenever you have two LANs that need to connect to the public Internet, you should think about using VPN technology or an equivalent method of protecting your business. In this case, the VPN software will probably work on the router, server and even the dedicated VPN server hardware.

We talked about two use cases above for consumer VPN services: data evaluation and location falsification. We'll talk about falsification later, so let's focus on data protection.

When you are away from home or the office and connect to the network, most often you do it via Wi-Fi provided by a hotel or restaurant, library or coffee shop where you work immediately. Sometimes Wi-Fi has a password. Other times it will be completely open. In any case, you have no idea who else has access to this network, and therefore you have no idea who can sniff at your guests.

I always recommend using a VPN when using someone else's Wi-Fi network. Here's a fantastic rule: if you're away from work or home and using someone's Wi-Fi, use a VPN. This is especially important when you access a service that contains personal data. Remember that a lot is happening behind the scenes and you never really know if one or more programs will authenticate in the background and put your information at risk.

How Norton Help in Security?

VPN can help an organization to established safe internet network. Along with VPN, Norton internet security antivirus program is additional benefit to secure internet. The company can secure their data privacy as much as they can. You can Activate my Norton antivirus on every possible device on your company to secure works
