Will A VPN Service Help Me Connect Securely To My Office Network

What is a VPN and how does a VPN work? | VPNpro

If you’re trying to connect to your on-premises corporate network, you’ll most likely be assigned a VPN application by your IT department. This will allow you to establish a point-to-point connection between your local device and a server owned and operated by your company.

But, if your company is cloud-based, and you’re connecting to SaaS applications like Salesforce or Google, you should probably use a VPN service since you’re not actually connecting to your company but instead to a public cloud application.

If your IT department does not specifically identify a VPN service you should use for accessing their public cloud applications, definitely look at our VPN directory and choose one of the higher-rated service providers.

What A VPN Cannot Do For You

A VPN does not block viruses. It can encrypt them just like it encrypts data you send over the network. But that wont help you if you were to browse an infected site or download infected files.

A VPN does not make you entirely invisible. Unless you have your own server and storage that you run completely on your own, you will have to trust someone with your data, whether thats your ISP or a VPN.

Is A VPN Legal

VPNs are not illegal in the United States. However, not all countries have the same laws regarding these services. For instance, China, Russia, and North Korea either regulate or ban VPNs. You should know, too, that if you commit an illegal act online using a a VPN, that act is still illegal. Customers often use VPNs so that they can stream sporting events and TV shows that they may be blocked from accessing in their own region. Using a VPN to pretend that you are logging onto the internet from a different location might violate the service agreements of streaming services.

VPNs Are Good For Securing Public Wi

The best use of a VPN is to add security to your connection when youre on public Wi-Fi from someone you dont knowat cafés, hotels, airports and airlines, and even car dealerships while youre waiting for your vehicles fuel-line recombobulator to be replaced. A bad actor or mischievous network owner can intercept and steal your personal data on these types of networks. Though network security has changed since 2014, a more recent vulnerability in 2017 shows that so too have the exploits and methods miscreants use to break it. A properly secured VPN can help deter this type of attack because it encrypts your connection starting with your computer, through the network, and out to the far-off VPN server.

Your Location For Streaming

What is a VPN and How does it Work? An Introduction For Newbie

You might pay for streaming services that enable you to watch things like professional sports. When you travel outside the country, the streaming service may not be available. There are good reasons for this, including contractual terms and regulations in other countries. Even so, a VPN would allow you to select an IP address in your home country. That would likely give you access to any event shown on your streaming service. You may also be able to avoid data or speed throttling.

What Happens If A VPN Connection Fails While I’m On A Remote Connection

A lot depends on what VPN you’re using, how it’s set up, and where you’re connecting. That said, let’s look at the most likely scenario.

Recall that when you’re online and connected to an internet application through a VPN, a few things are happening: Your data from your computer to the VPN service is encrypted by the VPN. Your data from the VPN service to the internet application may or may not be encrypted via https, but the VPN service does not encrypt it. And your IP address is spoofed. The online application sees the IP address of the VPN service, not of your laptop.

When a VPN connection drops, you might just lose your connection. But because the internet is very good at routing around failures, what is more likely to happen is your computer will reconnect to the internet application, simply bypassing the VPN service. That means that — on failure — your local IP address may “leak out” and be logged by the internet application, and your data may be open to local Wi-Fi hackers at your hotel or wherever you’re doing your computing.

There is a reasonably robust solution to that problem, and that’s next.

How Does A VPN Protect You During Online Activities

Do you shop online? Do you check your bank account from your mobile phone? Have you ever used a public Wi-Fi hotspot to access your email or social networks? While those are ordinary daily activities for most of us, they may compromise your online security and expose your most sensitive data to hackers. This particularly applies to users relying on public Wi-Fi.

So, what is VPN protection and how is it helpful in such a scenario? By encrypting your data traffic, it will make your data indetectable by hackers. Apart from preventing data theft and cyberattacks, powerful VPN protection also ensures that the websites collecting your private data cannot track your device.

Should I Leave My VPN On All The Time

If you want the most protection, you should leave your VPN on at all times. You should especially leave your VPN on when you are logging onto the internet using public Wi-Fi. These connections are notoriously unsecure, providing tempting targets for hackers and cybercriminals. You should also use a VPN whenever you are logging into your credit card or online banking accounts. You dont want to expose this sensitive financial information to online thieves.

VPN & Tor How To Use Them Together

VPNS (What they do, what I use) (DISCORD PROBLEM FIX)

Even though Tor and VPN are fundamentally different, they can still be used together for maximum security and online privacy.

  • Tor gives you the ability to access the web by routing your connection through a number of random nodes, while also encrypting that connection at every stage.
  • VPN gives you access to one server at a time.

The nature of it is a bit different in principle, and therefore we cant say things like Tor or VPN is better than the other. We talked about the differences between Tor and VPN in detail on this site already, feel free to visit that post to get the full picture.

One of the good things about Tor is that you can use it 100% free and there are no built-in limitations to that free version. All you need to do is grab the official Tor web browser. Once you have it, you just need to fire it up like your standard Chrome or Firefox browser, click the connect button, and youre up and running.

How to combine your VPN and Tor:

  • Enable your VPN connection normally. From this point on, everything that involves communicating with the web goes through your VPN.
  • Open your Tor browser and connect with Tor.

    The Best VPN Services To Hide Online

    Now that you understand a bit more about VPNs, youll want to search out the best provider. Unfortunately, the market has hit a saturation point with VPNs of all caliber, ranging from high monthly fees to seemingly free services. Well cut to the chasemost arent worth your time, as striking the right balance between privacy, performance, and price is delicate work.

    The following 6 VPNs are perfect for hiding your data, identity and activity online:

    NordVPN is a security-first VPN thats great for staying anonymous online. It has a number of features specifically made to protect you, help beat censorship, and unlock content. Everything starts with encryption NordVPN uses 256-bit AES keys that would take a supercomputer millions of years to crack. The specific encryption technologies used include OpenVPN, which blends speed and security, as well as less popular options like SSTP . The second layer of security comes from NordVPNs tough no-logging policy. The service doesnt store your browsing history, real IP address, traffic, bandwidth, and more which gives you a very high level of data privacy protection. Moreover, with the holding company being registered in neutral Panama, what little personal information NordVPN does have is unlikely to ever be released to a third party.

    How Does A VPN Work#

    A VPN conceals your IP address by routing it through a specially configured distant server hosted by a VPN host. This implies that if you use a VPN to access the web, the VPN server becomes the source of your data. This means that your Internet Service Provider and other third parties will not be able to see the websites you visit or the data you transmit and receive online. A VPN acts as a filter, converting all of your data into “gibberish.” Even if someone were to obtain your data, it would be worthless.

    Are The Free VPN Services Any Good

    10 Things To Know About What Does A VPN Hide And How Does ...

    There are some good free VPN services, but I avoid all free VPNs.

    Why? It costs a lot to provide the infrastructure to operate a VPN service, from the network pipes to the servers. That infrastructure has to be paid for somehow. If user fees do not pay for it, advertising, data gathering, or some nastier reason are likely to be paid for.

    Here’s another reason not to use a free service, and this one is a lot scarier: Malware providers and criminal organizations have set up free VPN services that not only don’t protect you but actively harvest personal data, and either use it or sell it to the highest bidder. Instead of being protected, you’re being plundered.

    Are There Any Downsides When Using A VPN

    As you can realize, a VPN can bring back a lot of fantastic benefits. However, as with any type of technology, therere also some drawbacks to using a VPN.

    Consider some cons of a VPN before you go ahead:

    • Potentially slower speed. Your web traffic will go through more steps than usual when connected via a VPN, so there could be a perceptible slowdown. People doing things online that need a speedy connection can have some problems with the wrong VPN service. Thats why its essential to check a VPNs speed when youre trying it out.

    • QoS challenges. QoS describes the performance of a network or service. As a matter of fact, VPNs havent had a standard in place to gauge and report such measurements yet. With no metrics to evaluate, you need to rely on professional reviews and word-of-mouth to choose the most reliable one.

    • No cookie protection. Although VPNs do their job of keeping you encrypted and secure, it is not possible for a VPN to block cookies, some of which are necessary to make websites work properly. One bad kind of cookies, tracking cookies, can still be stored in your browser and identify who you are.

    • No total privacy. While VPNs block your ISP, government, hackers, advertisers, and other snoops, the VPN provider itself can see your online activity if they want. Thats why its critical to choose a trustworthy provider that doesnt keep logs.

    In spite of the above disadvantages, VPNs are actually worth it if you care about online privacy.

    Types Of Virtual Private Network Protocols

    The protocol represents a set of rules and procedures used for data exchange in a network. It structures the data flows and the way devices send or receive information. A VPN service may offer many security protocols, and you can choose which ones to use, depending on what you want to do online.


    Almost every VPN software uses OpenVPN as a standard protocol. Its open source, thus allowing developers to implement their ideas and tailor it to suit their companys and clients needs.

    Once OpenVPN opens a tunnel for the information it uses a 256-bit OpenSSL encryption protocol and UDP User Datagram Protocol faster, but less secure protocol to transfer data back and forth. Or TCP Transmission Control Protocol more secure, but slower, compared to UDP.


    The Internet Protocol Security encrypts the data packets that go through the tunnel. Additionally, it verifies the session across the IP network. It can be combined with other security protocols to increase overall data protection.

    L2TP Layer 2 Tunneling Protocol

    L2TP is a protocol which supports the virtual private network by generating a tunnel. It doesnt provide any encryption, so it often comes hand in hand with IPSec.

    Point-to-Point Tunneling Protocol

    More familiar by its acronym PPTP, this is one of the oldest protocols for creating a Point-to-Point network. Enterprises use it to create LAN networks, but its also used in VPN connections. This protocol also creates a tunnel between two specific points

    A VPN Can Help You Save Money

    You might have come across expansive claims about how a VPN can help you save thousands of dollars. You can supposedly do so by finding cheaper subscription plans for software, streaming services, and other apps and programs. Even airfare, rental car rates, and hotel prices could be much lower when using a VPN.

    Im not going to scoff at this claim as it does work in theory. Certain pieces of software, streaming service subscriptions, and airline booking rates are priced differently across the world. You can use a VPN to see the differences, and its certainly worth the purchase if you can save big. However, you either have to be very, very lucky or make a lot of trial and error to save thousands of dollars.

    There are undoubtedly some differences in prices. That difference will likely get covered in currency exchange rates, bank fees, and other transaction charges, though. Other restrictions might also come into play, like a website not allowing the use of a credit card that isnt from a local bank.

    Granted, you may see significant savings in the long-term or if even youre planning a long holiday. Even five to ten dollar savings on everything will eventually add up to a pretty good amount. That said, you might want to re-think things if saving a lot of money is the main advantage youre looking for from a VPN service.

    Protecting You On Public Wi

    WHAT IS A VPNâ? Simple, non-technical explanation of how a VPN works!

    If you log into public Wi-Fi networks to get online, such as in a coffee shop or on the train to work, VPNs can keep your data private.

    Public Wi-Fi can be a great commodity, but it is not as safe as your work or home internet connection. Through a VPN tunnel, your data is fully encrypted. Until your data reaches its predetermined destination, it cant be deciphered, so you can browse, email, or pay by credit card securely even on a public Wi-Fi network.

    What A VPN Can Do For You

    Besides adding an additional layer of encryption, a VPN essentially hides or masks your IP address from websites. There are legitimate reasons why you wouldnt want a website to know your IP address. Among other things, your IP address tells websites where you are located. This could prevent you from accessing content that is not available in your region be it for marketing or even censorship reasons.

    A VPN Can Circumvent Some Internet Censorship

    Because they can geo-shift your location, VPNs can be useful tools to at least temporarily circumvent certain kinds of government censorship. But theyre not foolproof.

    In some countries, VPNs are sometimes the only way to access certain parts of the internet, including major sites like Facebook and WhatsApp. For example, in Myanmar, people turned to VPNs as the only way to access the news during a coup, as many people have long done to avoid Chinas Great Firewall which blocks hundreds of sites, ranging from Google to Bandcamp.

    Countries often play whack-a-mole with VPNs when people try to find ways around government censorship, as weve seen in Russia and China. This makes finding one that works in any given country difficult. Getting around access restrictions is also dependent on how the censorship technology works, and a VPN might not even be necessary. Other ways around these barriers include changing your DNS provider or using the Tor Browser.

    None of these tools are useful in cases where a government leans on private companies to block or control content, and a government can still take action against people who use a VPN and then post on social media. VPNs are also not helpful in places that restrict free speech through laws, rather than by blocking websites.
