  • Stay safe while using public Wi-Fi.
  • Stay safe while peer-to-peer gaming or file sharing.
  • Stop nosey sites from tracking you.
  • Speak out safely as a journalist or political dissident in a repressive country.
  • Watch streaming video content from another country.

VPN services, such as Malwarebytes are consumer level VPNs. This means as the VPN provider, they are responsible for the servers, the encryption, and the user authentication. All you need to do is pay your subscription fee and they take care of the rest!

VPN Vendors And Products

VPN services are available in free or paid options. Paid vendor options tend to be recommended more often than free ones, however. Some example vendors include the following:

  • NordVPN contains a strong collection of security features with a large collection of servers. NordVPN has features such as Tor connections, while maintaining a strong stance on customer privacy.
  • Private Internet Access is an app for iOS and Android that can support up to 10 different simultaneous connections. It does not offer too much in terms of extra features and privacy tools, however. Still, it is generally seen to be a good VPN service.
  • ExpressVPN is a VPN service with a large and diverse set of distributed servers. It has strong privacy and information practices focused on security and offers extra features such as split tunneling. It also uses the OpenVPN protocol.

Why Do You Need A VPN

  • Safeguard your personal information

This is truly the era of mobility. The majority of people are accessing the internet on the go using their mobile devices, exchanging massive amounts of data over public networks in the process. From online shopping to mobile banking, or simply checking emails and social media accounts, the number of ways your personal information and sensitive data can be exposed to hackers and cybercriminals is a real concern.

People who frequently access the internet using public Wi-Fi networks are at a greater risk. Using a VPN will help mitigate unwanted data leakage and theft of your personal information by securing your data as it is transferred across the internet.

  • Access region-restricted streaming content

One of the main reasons people use VPNs is to access region-locked streaming content and websites. Popular streaming services limit their viewable content depending on which country you access their sites from. As a result, it may not be possible to watch your favorite movie or TV show without the use of a VPN. VPNs allow you to choose which country you appear to be connecting to the internet from, enabling you to view streaming content that may not be available in your country. They also allow you to access websites and social media platforms that may be restricted in your country, too.

  • Enhance your browsing privacy
  • Save money when communicating with family and friends abroad
  • Escape content-based bandwidth throttling

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.

Osi Layer 3 Ppvpn Architectures

How to Stay Safe on Public Wi

This section discusses the main architectures for PPVPNs, one where the PE disambiguates duplicate addresses in a single routing instance, and the other, virtual router, in which the PE contains a virtual router instance per VPN. The former approach, and its variants, have gained the most attention.

One of the challenges of PPVPNs involves different customers using the same address space, especially the IPv4 private address space. The provider must be able to disambiguate overlapping addresses in the multiple customers’ PPVPNs.


In the method defined by RFC 2547, BGP extensions advertise routes in the IPv4 VPN address family, which are of the form of 12-byte strings, beginning with an 8-byte route distinguisher and ending with a 4-byte IPv4 address. RDs disambiguate otherwise duplicate addresses in the same PE.

PEs understand the topology of each VPN, which are interconnected with MPLS tunnels either directly or via P routers. In MPLS terminology, the P routers are Label Switch Routers without awareness of VPNs.

Virtual router PPVPN

The virtual router architecture, as opposed to BGP/MPLS techniques, requires no modification to existing routing protocols such as BGP. By the provisioning of logically independent routing domains, the customer operating a VPN is completely responsible for the address space. In the various MPLS tunnels, the different PPVPNs are disambiguated by their label but do not need routing distinguishers.

Speed Security And Privacy

People turn to VPNs for different reasons, and whatever yours is, you need to ask three questions before choosing a provider. How fast is it? Will it keep my data safe? And will it respect my privacy? Of course, you want your connections to be safe and your data to stay private. But to have all that without losing any speed? Thats the trick. So when you choose a VPN service, make sure they dont make any compromises theres no point in having unbreakable encryption if every website takes ages to load.

Hide Your Private Information

INE Cyber Security VPN Basics

Hackers can use a variety of methods to intercept sensitive information you enter on websites. Using that information, they can try to impersonate you, gaining access to bank accounts, credit card information, and more. With a VPN, however, you can enjoy high-level security, such as 256-bit encryption. This makes all your communications online look like nonsensical, garbled text and characters to anyone who is able to find a way to intercept them.

Safe Access To Cloud Services

Cloud-based services have become popular with businesses because they saw the potential it has to contribute to their productivity, thats why companies have integrated cloud services into their everyday work. Nonetheless, the cloud is still a cybersecurity hazard. Hackers can exploit your companys usage of cloud services to steal information.

Once you have installed a VPN, the data you stored on cloud servers will be safe and sound. All of your cloud-based assets are now secure from any malicious attempts of a breach from outside forces.

Are Free VPNs Safe

You can choose from many free VPNs. This could be useful if you are on a limited budget. Be aware, though, that free VPN services might not provide the same type of browsing privacy that pay services offer. Free VPNs have to make money somehow. They might do this by tracking and collecting your browsing data and selling it to third parties, like advertisers. Others might hit you with a steady stream of online ads. Free VPNs might be easier on your wallet, but using one might compromise some of your privacy.

What Does No Logging Mean

No logging means that your VPN provider doesnt keep any records of what you do while using the VPN. A no-log VPN provider wont track or store any information sent over the VPN connection they know only your IP address, payment information, and the VPN server you use while connected.

Whenever an activity happens on a computer, that event is logged. Since servers are computers, they collect information by default whenever theyre accessed by a device such as yours.

Before choosing a VPN, read the providers privacy policy closely to see exactly what type of information they collect and keep. If your VPN is storing your browsing history, then it defeats the purpose of using a VPN service for internet privacy and security.

Free VPN Versus Paid VPN

VPN. virtual private network. secure vpn connection ...

Running a good VPN service costs serious money robust servers, data transfer, infrastructure, employees, and so on. If the service is offered for free, consider what compromises may have been made. Are they logging activity for their own reasons? Are they displaying their own ads? Is your data being sold to a third party?

Paying for a VPN isnt a huge investment. Weve tested some great solutions for as little as $3-5 per month, which doesnt seem a lot in exchange for peace of mind and improved online privacy.

How Much Does a VPN Cost?

The average out of 70 popular VPNs is $4.99 a month, which tells you a lot about what sort of an expense this usually is. VPNs that cost more than $10 are uncommon, and theres not a lot of reason to buy them since there are more affordable solutions out there.

Most services give out big discounts if youre willing to subscribe for two to three years up front, instead of renewing your subscription monthly. For example, NordVPN a VPN that we very much enjoy costs $11.95 if paid monthly, but you can grab their 3-year plan for just $3.49/month .

Your Ip Address And Location

Anyone who captures your IP address can access what youve been searching on the internet and where you were located when you searched. Think of your IP address as the return address youd put on a letter. It leads back to your device.

Since a VPN uses an IP address thats not your own, it allows you to maintain your online privacy and search the web anonymously. Youre also protected against having your search history gathered, viewed, or sold. Keep in mind, your search history can still be viewed if you are using a public computer or one provided by your employer, school, or other organization.

VPN Encryption Boosts Network Security

Encryption scrambles data so only authorized users can see it. Hackers, fraudsters or other bad actors who manage to intercept it are out of luck.

Even if cyber fraudsters intercept your data, its safe inside the VPN tunnel.

Lets assume an employee is working from a cafe, shared workspace, hotel, or airport, and that employee is authorized to access your companys business-grade VPN. Using a VPN client installed on their device of choice, and a public WiFi network, the employee can establish an encrypted connection between the users device and your VPN. That device, and any other that connects to your VPN, will set up encryption keys on both ends of the network connection. Those keys will then encode and decode the information being shared back and forth.

Once the employee working at the cafe establishes an encrypted VPN connection, using the cafes WiFi as a hotspot with a VPN client, their data is protected by the VPN. Even if cyber fraudsters manage to get into the cafes network, your employee, and their data, is safe inside the VPN tunnel.

How Can Cybersecurity Defend Against Attacks Threats Vulnerabilities & Risks

Cyber Security Course: 20 Data in Transit Lab – VPN. Learn Internet Security

Most cybersecurity strategies cant provide full protectionthey can only mitigate risks and reduce the probability of threats. For instance, a Layer 7 DDoS attack with a massive amount of traffic from geographically distributed sources is nearly impossible to stop. But deploying a CDN with scrubbing data centers to clean the junk traffic and L7 WAFs to filter further will help mitigate the risk.

The Predecessors Of The VPN

Their efforts led to the creation of ARPANET , a packet switching network, which in turn led to the development of the Transfer Control Protocol/Internet Protocol .

The TCP/IP had four levels: Link, internet, transport and application. At the internet level, local networks and devices could be connected to the universal network and this is where the risk of exposure became clear. In 1993, a team from Columbia University and AT& T Bell Labs finally succeeded in creating a kind of first version of the modern VPN, known as swIPe: Software IP encryption protocol.

In the following year, Wei Xu developed the IPSec network, an internet security protocol that authenticates and encrypts information packets shared online. In 1996, a Microsoft employee named Gurdeep Singh-Pall created a Peer-to-Peer Tunneling Protocol .

How Much Does A VPN Cost

Compare a VPN providers price to the level of service they provide. One VPN might be cheaper than another, but does it let you connect as many devices at the same time? Does it have as many server locations as another VPN? Consider these factors when evaluating VPNs by price.

Here, weve listed the monthly prices for each VPN, though several VPNs bill annually. Many of these VPN providers offer lower rates with longer subscription commitments or special promotions.

  • Avast SecureLine VPN: $7.50/month
