What Is A VPN And How Does It Help

What is a VPN?

A VPN is a tool for security and privacy, but it can do way more than that. So if you ever asked yourself, Why do I need a VPN? read on to find out. Heres how a virtual private network helps:

  • Encryption. A VPN encrypts your traffic so that it becomes virtually indecipherable to third parties.
  • Hiding your IP. A VPN hides your IP, which in turn hides your location as well. Access to Netflix. With a VPN, youll be able to watch your movies and shows outside your home country.
  • Torrenting protection. A VPN will protect you when torrenting.
  • Firewall circumvention. From the ones at your office to the ones used in China, firewalls block certain websites from users. VPNs allow you to circumvent these restrictions.
  • Wi-Fi protection. Finally, a VPN will protect your connection on public Wi-Fi and help avoid bandwidth throttling. Some Virtual Private Networks even offer anti-malware solutions.

How Does VPN Tunneling Work

To connect to the internet through a VPN tunnel, you’ll first have to sign up with a virtual private network service, better known as a VPN. The VPN is the key to hiding your IP address and shielding your online activity from snoops.

Before visiting websites, you’ll log into your VPN providers service. When you then start searching online, the websites you visit and your own internet service provider ISP, for short won’t see your IP address. Instead, they’ll see the IP address of your VPN provider, helping to protect your privacy.

In essence, when you click on links or download files from a site, no one will know its your activity. Its as if your VPN provider has built a tunnel around your online activity, providing a barrier between it and everyone else.

Using a VPN alone may not be enough to protect your online privacy, though. Thats why VPN providers take one more step to encrypt the data you send and receive while you are online. When your data is encrypted, it is scrambled so snoops cant intercept and decipher it.

When you enable this added layer of protection, hackers, businesses, governments, or others won’t be able to track what sites you visit, files you download, videos you stream, or online games you play.

Hiding your IP address and encrypting the data you send and receive is a powerful combination to help keep your online browsing sessions private.

Different Types Of VPN Tunneling Protocols

The VPN industry gave birth to a variety of tunneling protocols.

Some of them are considered old and less secure.

Some have been introduced relatively recently and are perceived to be the industry-standard both in terms of speed and protection.

Currently, the most commonly used VPN protocols are PPTP, L2TP/IPSec, SSTP, and OpenVPN protocols.

Now, lets talk a bit about them.

Are There Free Versions And Does It Matter

Many of the top providers offer free versions of their VPNs. But the free versions may be limitations for instance, on how much data you can use.

Some VPN providers offer free trials of their paid versions. The trials typically run for about a month. Some allow to access most of the VPN features of the paid service, although there may be data limitations.

If you sign up for a free trial, you provide the same personal and payment information youd use if you were signing up for the paid service. You can cancel your account before the end of the trial. If you dont cancel, the provider will begin to bill you for continuing service.

Keep in mind, some free VPNs may collect and share or sell your data to third parties for marketing purposes, while others may not block ads.

How Does Pptp Work

5 VPN Functions for Internet Activity

PPTP Point-to-Point Tunneling Protocol is a method of creating a virtual private network VPN. One way to imagine PPTP would be a freeway running from point A to point B. The freeway has lots of tow trucks driving from one side to the other, carrying things that need it to need to deliver to either Point a or Point B.

Now lets imagine there is a helicopter looking down and that these tow trucks have no roof and can see everything they are transporting. PPTP does something special for that it creates its tunnel for trucks to pass through it. From the helicopter, you can only see that the trucks go from Point A to Point B, but we will not be able to see anything that is inside it.

All you can know is that there is a connection between two points the rest is out of sight from view. In the same way, when users want to connect to their hotel network or public Wi-Fi securely, they dont want other people to be able to see what they are doing, so they have to use a PPTP VPN, to create an encrypted tunnel to protect your data.

A VPN is a secure connection established between your InternetService Provider and the other VPN internet service provider. When you use a VPN, all your online activity is encrypted, so attempts to break internet connections to steal private and confidential information will be in vain since internet traffic gets hidden behind the VPN.

What Is A VPN Privacy Policy

While many VPN service providers boast of having a strict no-logs policy, the reality is often contradictory. Minimum data logging is needed if the user pays with a credit card or other non-anonymous method, so theres nothing to worry about here. Its the other things you should look out for in the Privacy Policy: logging IP addresses, DNS queries, etc.

In any case, we can group all VPNs and their privacy policies into these categories:

  • Verified no-logs policy. On rare occasions, VPN providers have to cooperate with law enforcement agencies. Yet even when they do, no information about a user can be gained from the VPN servers. Such VPNs have a no-logs policy and can be trusted. Examples include Private Internet Access.
  • Independently-audited no-logs policy. Some VPNs like NordVPN or VyprVPN invest in having their no-logs policies audited by a third party, which is a sign that theyre serious about your privacy.
  • Minimal logging. Some providers like CyberGhost claim to do minimal logging, and were inclined to trust them for the time being because they rank high in other areas, such as security.
  • More than minimal logging. These services, such as TunnelBear, should be used cautiously because they care less about your privacy.
  • Extensive logging. Finally, we have services that collect as much data as possible and probably sell it to third parties. Thats why they have no problem with handing over your information to authorities if needed.

How Many Servers Are There

VPN providers with lots of servers can spread their users out to avoid overloading any one server. This ensures faster and more stable connections for everyone. Wondering how many servers your chosen VPN has? Weve got the numbers right here:

  • Avast SecureLine VPN: 700+ servers

  • AVG Secure VPN: 700+ servers

  • CyberGhost: 6,900+ servers

  • TunnelBear: Approximately 3,000 servers

Is Using A VPN Safe

A quality VPN is a safer way to search the internet. Without a VPN, your browsing and downloading activity could be visible to hackers, snoops, and cybercriminals. A hacker could intercept your email messages, mine personal data such as your Social Security number, or uncover the password to your online banking portal or credit card. Any of this could expose you to identity theft or fraud. That’s why logging onto a VPN, which protects your privacy, is one of the safest ways to browse the web.

In the current cyber security landscape, businesses cant be too careful. More dangerous and damaging risks are constantly emerging, and many of them directly align with enterprise technology trends.

Take, for example, the rise of remote working. According to Global Workplace Analytics, 4.3 million workers now operate from home or locations outside of the regular office at least half the time. Whats more, 50% of the entire American workforce has a position that would lend itself well to partial teleworking, and upwards of 90% percent of U.S. employees say theyd appreciate the ability to work from home part time.

As more staff members work remotely, though, this creates risks surrounding their access to sensitive company data and tools. Without a completely secure connection that helps eliminate the risk of cyber snooping and unauthorized access, these remote employees drive up the digital security threats for their employers.

Enter Virtual Private Networks , an advanced solution to enabling security for remote business employees. Lets take a closer examination of this technology, including how VPN works, the benefits for enterprise users, and how to set one up.

How Can A VPN Help Protect Against Identity Theft

Identity theft occurs when cybercriminals steal your personal information and use it to commit crimes in your name like taking over or opening new accounts, filing tax returns in your name, renting or buying property.

So many things may happen out there that a data breach can also occur at an organization where you have an account which is out of your control.

In conclusion, VPN actually has lots of positive sides which a lot of people dont know and I presume maybe because they havent been opportune to learn about it.

What VPN Providers Are There

Above we have shown you three good VPN providers but there are hundreds of companies that offer commercial VPNs. Just type in VPN in the App Store or Play Store, and youll see a dizzying amount of VPN apps, that are often free to download. And then there are also quite a few companies that offer business VPN packages.

We like to help and have tested many VPN providers already. You can find more information about testing and the results in our VPN review section.

Below youll find a selection of VPN providers to give you an impression of the amount of services out there. We also state under which jurisdiction each VPN provider falls and whether the VPN provider is located in a 5, 9 or 14 eyes country the governments of these countries exchange information.

The jurisdiction may have implications for the privacy of VPN users, as each country has different privacy laws. In practice, there are therefore differences in which user data VPN providers store. With privacy in mind, you ideally want to use a VPN that doesnt log or track anything about your internet activities.

Secure Your Data Over Public Wi

The convenience of free public Wi-Fi often comes with a loss of security. Since anyone can hop onto an unsecured Wi-Fi network, theres no way to know exactly whos connected at any given time, or what theyre doing. Its easy for a hacker to sit on a public Wi-Fi network and intercept all the traffic flowing across it.

If you log into your bank account, check your email, or hang out on social media, a hacker can snap up your login credentials. Any messages you send or personal data you transmit can be intercepted and used for blackmail or identity theft. The risks of public Wi-Fi are almost endless.

Because a VPN connection encrypts your communication with its server, anyone trying to eavesdrop on the public network will see only gibberish. Thats a big part of what VPN protection is: ensuring that no one can access your data.

How A VPN Works

What is the purpose of a VPN software?

A VPN works by routing your devices internet connection through your chosen VPNs private server rather than your internet service provider so that when your data is transmitted to the internet, it comes from the VPN rather than your computer. The VPN acts as an intermediary of sorts as you connect to the internet, thereby hiding your IP address the string of numbers your ISP assigns your device and protecting your identity. Furthermore, if your data is somehow intercepted, it will be unreadable until it reaches its final destination.

A VPN creates a private tunnel from your device to the internet and hides your vital data through something that is known as encryption.

Security On Public Wi

Public Wi-Fi is convenient but comes at the expense of security. When youre answering emails at a local coffee shop or absent-mindedly scrolling through social media at the airport, someone may be tracking your online activity.

Using a VPN protects your data while you are on other networks, hiding your browsing history, banking information, account passwords and more from ill-intentioned internet strangers.

What Is VPN Encryption

VPN encryption is the process of using data encryption to create a secure tunnel for your data to travel through. If anyone examines your VPN connection, theyll see scrambled data. Only your device and the VPN server youre using can encrypt and decrypt, or unscramble, your data.

While many encryption methods, or algorithms, exist, most VPNs use the 256-bit AES algorithm. This level of encryption is so secure that its used by banks and governments worldwide as well as by AVG Secure VPN.

Browsing Without A VPN: What Makes Your Data Valuable

When surfing the web, you constantly send and receive data packets. These packets contain your IP address because they need to know where to go and come back.

Without a Virtual Private Network, your Internet Service Provider and websites can see where these packets travel and what data comes with them. This allows them to monitor, log, and later sell this information.

Why do they care? Your data is valuable to ad brokers and other service providers because it reveals patterns in your actions, such as likes, hobbies, and interests. This can later be used to make product offers youre more likely to buy.

The amount of information these companies collect and store has also become a privacy hazard. Data breaches happen all the time, affecting billions every year.

All that information eventually ends up on the dark web. This can lead to massphishing campaigns and evenidentity theft. So, its better to protect your privacy and data in the first place!

What Are Advanced VPN Features

Remote Access / Virtual Private Network (VPN) Explanation

Almost all high-quality commercial VPN software will have a setting or preferences menu where sub-menus such as security or advanced options are located in the application. The features will also vary slightly across different platforms e.g. laptop and smartphone options may differ. Since VPN providers need to diversify and have unique selling points in order to compete in the market, there will be signature options that differ between VPN providers. These features in general include options such as

  • Auto-connect options
  • Presets that prioritize speed, downloads, and more
  • VPN protocol selection options
  • Routing over the Onion network
  • Malware, tracker, and ad blocking features

Lets cover the most significant of these options briefly and why you need to have them enabled.

Keeping VPN Traffic In The Tunnel

Most VPNs rely on tunneling to create a private network that reaches across the internet. In our article “How does the internet work?” we describe how each data file is broken into a series of packets to be sent and received by computers connected to the internet. Tunneling is the process of placing an entire packet within another packet before it’s transported over the internet. That outer packet protects the contents from public view and ensures that the packet moves within a virtual tunnel.

This layering of packets is called encapsulation. Computers or other network devices at both ends of the tunnel, called tunnel interfaces, can encapsulate outgoing packets and reopen incoming packets. Users and IT personnel configure the tunnel interfaces they’re responsible for to use a tunneling protocol. Also called an encapsulation protocol, a tunneling protocol is a standardized way to encapsulate packets . Later in this article, you can read about the different tunneling protocols used by VPNs.

To better understand the relationships between protocols, think of tunneling as having a computer delivered to you by a shipping company. The vendor who is sending you the computer packs the computer in a box . Shippers then place that box on a shipping truck at the vendor’s warehouse . The truck travels over the highways to your home and delivers the computer. You open the box and remove the computer .

How Does A Virtual Private Network Work

A VPN extends a corporate network through encrypted connections made over the Internet. Because the traffic is encrypted between the device and the network, traffic remains private as it travels. An employee can work outside the office and still securely connect to the corporate network. Even smartphones and tablets can connect through a VPN.

What Is A VPN And How Does It Work

A VPN establishes a private, encrypted network connection over the internet. In other words, it enables data to travel through a protected tunnel, from the end users device to the corporate network.

As Cisco explains, one can think of a VPN as a protected extension of the main corporate network, accessible from outside of the main office. In this way, employees can work from their home office, the local coffee shop, the airport, or nearly any other location with internet access and still operate in a secure manner as they would from their regular, office desktop computer.

Because the traffic is encrypted between the device and the network, traffic remains private as it travels, Cisco states. Even smartphones and tablets can connect through a VPN.

Encryption ensures that any data accessed or other actions taken by remote employees are protected and safeguarded from unauthorized, prying eyes that might exist over public Wi-Fi connections.
