What is a VPN? VPN stands for virtual private network. A VPN is what establishes a secure and reliable network connection over an unsecure network such as the internet. It protects your internet traffic and disguises your identity as you surf the internet.

please talk about ACL -ACCESSE CONTROLE LIST-
If you look at your internet traffic with full spectrum rf, you'll most likely see that outside the data stream there's a second side stream, that is sending all of your DNS requests somewhere. If not you're ISP, then whom?
Is VPN the same as IPSec? Are they the same topic?
I’ve watched dozens of your videos since discovering your channel a few days ago. Your ability to simply explain complex technologies is amazing.❤
Glad you like them!
literally me. Going through the google IT support course on coursera and these videos on here are way better explaining topics
Yes, it's splendid explained and I like the voice.
Today while browsing I come across your link it's amazing.
It would be wonderful if you can provide some classes on networking as I work for Network company
I'm never as excited to learn as I am whenever you upload a new video. Greatest explanations ever!
Thank you Professor PowerCert ! You have this uncanny ability to explain technical concepts in a manner that is easy to understand.
I have just subscribed after watching one video. You have a knack for delivering video content while faceless. Your way of explanation is awesomely on another level. One can easily comprehend the concepts and the flow of information fully. Keep it up.
I've just been really confused about VPNs all the time, but your video made me instantly understand all of it. Love your videos
Also, some VPN providers (most of the time free ones) act often like ISPs, as they sell to third parties your activity on their VPN
Fact
Yep.
Been following your videos for a while now, it helped me a lot, thank you.
Hey your effort towards providing the quality content is just amazing!!
I just wanted to say you that please make a complete detailed video on the OSI and TCP/IP MODEL. That would be really helpful 😌
Thank God i found this channel! Thank you so much PCAV! You explain things so well and the animations help the information stick to my brain. I've learned so much from your videos with your "explain it like im 5" animations more than other sources! You should sign up as a Udemy teacher! I'd definitely pay top price for your class!!
I could completely relate to the remote work part, as my IT Director is adamant about everyone using a VPN, as 95% of our workforce at my employer are fully remote.
I love this channel, your content is great, I've been following you a few years now and when I need to refresh/learn something this is the first place I try to go
I really like this channel because it has the ability to explain sometimes difficult concepts in easy and fast way. However sometimes faster isn't always better and it does leave a lot of room for deception and dishonesty about product that people don't actually need (like in this case) ...
Care to back up that claim of dishonesty & deception with some examples?
Explanation with animation is brilliant!
Great video as always. One thing I wanted you to mention is different TYPES of vpn, like peer-to-peer, web-to-web or something like that.
Beautiful work as always. Thank you so much.
Man! Your learning videos are interesting enough! Adding funny stuff in them, (like the flaming coffee pot!) is the whipped cream and cherry on top!
These videos are gold ! Keep going and thank you so much for making them!
hey, thanks for making this video...I've been following your videos for sometime. I'm now watching them as you post them.😀
Clearly explained!Well done bro 👍
Love your Channel! Thank you for creating helpful and straight forward videos.
A note about traffic logging: as of this writing, to the best of my knowledge, VPN providers aren't required, in some areas, to log traffic data. With NordVPN in particular, they will comply with law enforcement requests after putting law enforcement through the ringer, but the only records they would have would be payment data and email addresses. Still, that's something. Obviously, a discussion on completely anonymizing and privatizing one's Internet activities falls outside the scope of this video (encrypted DNS, Tor, and how those might even have their vulnerabilities), but kudos on yet again another simple, straight forward explanation on what a thing is, how it works, what it does, etc.
5 eyes, 7 eyes, 14 eyes.
VPNs must comply with a legally acquired court order. Of course, some VPNs use RAM storage (not Nord). Switch off the server and the data is lost forever. The danger with TOR is you never know who is in control of the exit node, hackers, law enforcement...
Safest but slowest is TOR over VPN.
@@ianl1052 "VPNs must comply..." I didn't state otherwise.
"Some VPNs use RAM storage...." Interesting!
"The danger with TOR...." Yep! As stated, "and how those might even have their vulnerabilities."
"Safest but slowest...." Yep. And don't forget your encrypted DNS. That's not to say it's all impregnable, but those are good steps to have in place...
...as of this writing. :-)

Agreed. If in doubt, we should all remember the golden rule. "The Internet never forgets."
@@ianl1052 Aye. Witness the Utah Data Center.

Biggest issues I don't see being talked about here are how VPN's are not actually one shoe fits all service...
There are many more issues not covered in this video about how still even while using a VPN you are not actually 100% safe and secure but the fundamental layout of this video is pretty accurate for the most part and is exactly how I would explain it to a kid or elderly person.
There is still some major technical flaws in VPN's like:
1.) ISP's still know you are using a VPN, as they are able to see your connection to the VPN servers. (Unless masked which some provide)
2.) Shared IP's on these servers are almost always flagged for fraud or spam, causing more issues like Captchas and not being able to use them for purchases. (Annoying for daily use)
3.) VPN's are not magic, it just adds an extra hop in your routing which, usually cause more latency. ("Gaming VPN's" are a gimmick)
4.) Your data is almost always end-to-end encrypted WITHOUT a VPN by HTTPS & SSL already so you get red flags if you connect to an unsecure site. (End-to-End Encrypted VPN is pointless)
5.) Who is providing your DNS? If its your ISP's DNS then your VPN is worthless because they know what domains you are resolving anyways.
Without going on and on though..
its so hard to find honest reviews and information online about VPN's anymore.
Most of these people running these channels don't care what company actually has more credibility or security or who is actually offering a higher quality service.
All they know is the sponsors is willing to pay them and the referral link will make them some passive income when people use it.

Thanks for another great lesson.👍

Those hacker jokes at the end, and dude, that coffee pot is on fire. Lol!
Great video, as always. I think you could have mentioned some downsides of VPNs. For example: VPNs can slow your internet speed. Some sites might not accept VPN connections. Some VPNs will disconnect, and reconnect; even if this is done momentarily, it can be long enough to gather data about you.
Good point!
It depends what servers you choose that will slow down your speed.
Thanks for the quick tutorial on VPNs.👍
Thank you for your thorough explanation. I'm Nigerian, and from mid 2021 to early 2022, our government banned Twitter (because we were insulting them on it), so a lot of us downloaded VPNs to access Twitter. I've always wanted to how that worked. Great video!
best channel for me in the world.
i have binhed watched all videos and continue to do so.
Explained it really well for me thanks!
My school use your video like documentary and teach student like us. Thank you for your hard work ! Because OMG !!! my teacher explain things so bad to the point where I have to watch your video to understand what he say xD
Thanks :)
Yes but remember to get the whole story and not just snippets of a explanation video!
You can set up your own VPN on your broadband router for remote access to your office server.
I like your explanation, but i would like more if you could list some trade off like disadvantages or limitation of vpn as well.
Wonderful explanation 👏 can you please make a video on what an endpoint is and how is it accessed using API s?
Very straightforward and helpful! Thanks!!
You have done it again sir, straight to the point and very concise. Your content is awesome. Thank you!
One question though, let's say you pay for a VPN here in America right and let's say you visit a country overseas would you be able to connect to the same VPN server in America or it has to be something closer to where you are located?
@Murray Wight Thanks!
Great video yet again !
Your explanation is very awesome .
Do you do videos on cyber security? Love your vids!
Excellent content. amazing teacher
very beautiful animation! thanks for the lesson!
Glad you liked it!
Explanation is great .
This is so helpful even I use these videos while learning Azure Cloud.
Thank you so much💗 ur explanation is the best
I love your explanations...very clear !!! would you please make a video for difference between DNS and cdn ? and what is a cdn ?♥
Noted
Some online sites (streaming, banking, etc) have blacklisted known VPN server addresses so your connection may bug out. Always best to give a VPN service a good work out during the trial period. All you have done is swapped out your current ISP tracking for a VPN further down the road.
Good one... Simple to understand...❤
Please make a video on Circuit switching vs Packet Switching. Thanks.
Isn’t circuit switching mostly archaic at this point?
Thank youuuuu! For imparting education to lay persons like me! Most browsers allow browsing incognito. Does that add an extra layer of safety?
Thank you for another great video.
Great videos. Could you do one on ssh tunelling (and how come ssh can avoid “the network stack” to change port numbers) please ?
A well explained video on what VPN's are. I especially liked the Hacker in the coffee shop. Nice touch, PowerCert
Thanks! 😃
The mug of coffee was really cool.
Could you do a video on Active Directory, Azure and LDAP?
Hi sir, i am from India..Your videos are Excellent. your way of teaching is awesome easily understandable.But one thing i request u to Please make Video about OSI and TCP/IPmodel..
Can you please explain in more detail how tunneling works? Is it the data just encrypted? And also, how does a VPN protect you from fake AP since you are connected to it directly?
Could you go over the OSI model layers and their functions?
I get so excited for each new video. As usual, great video
Yeah, me too.............these videos are pure gold.
Glad to hear it!
Thank you, teacher, really you explain very very well, and thanks very much for turkhis subtitles
Hello. Great video. (Are you the LearnLinuxTV guy?). How can a VPN bypass the ISP, if it is using the ISP's router in the home?
I would like to see a more indepth videos from you. If you use a VPN you still need to go through your ISP, you are not avoiding them. Only thing is your connection is encrypted and even that, which parts are encrypted. I suppose destination of the packet must not be encrypted. Also are packets encrypted only between you and a VPN server but I guess it is not encrypted between VPN and whichever site you are trying to access?
Its amazing, well explained in 7 minutes
I have a subscription with STC for internet service, but my home does not have an landline extension, so STC has partnered with Mobily to provide the connection. As such, I was provided two devices: one from Mobily (that is connected to a fiber optic cable) and a router from STC. Is there any way that I can activate the Mobily device and do away with requiring the second STC router ?
Best Channel So far :D 💥
great explain thank you
Even though the connection is secure between you and a specific server with a VPN, if you connect to a bad server (such as fake websites, scam downloads and so on), it no longer protects you. A VPN secures the connection, but it doesn't protect you from the server your are connecting with.
True. I just protects the data as it travels to the destination.
A VPN only protects communication between the end-points of the VPN connection, it does not protect the data to the destination.
But it still useful cuz it mask your IP address right?
yes
@@PowerCertAnimatedVideos I was going to ask this anyways, but what about a VPN offered by your protection software? I noticed that Norton has a VPN, would that be safer, as they'd also be protecting against hackers and malware.
And two other questions:
1) If your IP address is changed, won't that cause a problem with previously saved/bookmarked websites? Wouldn't you have to reconnect/re-subscribe to each of them?
2) I can see it being useful on your laptop or cell phone, but would it be absolutely necessary on your desktop?
this one could use a follow up with more detail around how the encryption/tunneling works, at least practically
Thank for your explanation. I have a question,Do the packets go directly to the VPN server or they go first to the ISP server and then routed to the VPN server?
They have to go through your ISP first. There's no other way since the ISP is the company that provides you with internet access. Your ISP will then forward the packets to the VPN provider which in turn will forward the packets to their intended destination.
Thank you sir 🙏
I hope you make a video on Graphics cards!
Freaking love you PowerCert
The coffee maker started burning at the end of the video 😁
You are a gem, awesome.
Please make a video about CORS and same-origin policy!
Great illustrated
We need to know how to establish VPN connection for Free!
can you make a video about routing tables please!!🙏🏻🙏🏻🙏🏻
Loves these videos!
Nice explanation. Often a VPN will really slow down your thruput. Often a trade off between safety & speed.
Yes, true
Thank you very much!
Amazing!
Is the burning coffee pot a result of the HTCPCP(Hyper Text Coffee Pot Control Protocol) implementation?
good one :)
Even the VPN providers can have our original IP and can share with government or companies right?
Yes...if they chose to. But they are not supposed to if it's in their terms of service.
@@PowerCertAnimatedVideos so it's like trying to be secured in an unsecured environment 😂
This is how data is shared and miss used
@@yashsakhare5399😅😅😅
No matter what it's about a chain of trust. So you have to ask yourself who do you trust more. Your ISP or VPN provider. No way around it.....except Tor, but that's a whole different thing.
Sir, we have to say thank you for this VPN-based video, perfectly explained, just have one question is real that ISPs does not reach our web search via VPN? and does ANTI-Virus software's VPN include to paid VPNs, or VPN has to be bought from additional vendor for this purpose?
I don't understand your first question. Some antivirus programs have a built-in VPN, but that depends entirely on the software and/or subscription in question.
finally a good explanation of vpn
Thanks for the Teaching on VPN, it's the best, very clear.... I don't have any credit card but am very much interested, because you made it very simple and clear. Thanks
Which app do you use to create such slides? its so nice
big fan !!

Great explanation. How do you know the VPN isn’t logging your activities?
Exactly!
Hello sir I hope you can make a video explain what is integers range in a computer ❤❤❤ I am a BSIT 1st year student
Good video, the question is why I should blindly trust a vpn provider more than my local isp provider, there is no guarantee about how they use my information, at least my provider is in my country and is subject to known laws, but what about vpn providers located in certain countries that don"t care about privacy or personal data ? I never use public wifi, roaming or a brand new sim card is more secure and afterall we can survive without being online all the time
Can you circumvent the European Digital Services Act with a VPN?
What guarantee is there that the ISP hasn't set up their own VPN? Or that the VPN you've chosen hasn't made deals to sell your IP?
If the site has SSL enabled, you should be safe using public Wifi (unless it is a compromised connection). You only need a VPN to hide from your ISP.
Not certainly. Though with SSL/TLS certificates your data are encrypted before leaving your device (mobile or phone), with a hacker being able to capture these data, he can perform rather bruteforce attack to crack these data. Obviously, most valuable part is the password.
But, to be honest, I am not really sure, if the encrypted data are one continuous pile or it can be distinguished.
@@andrejpovala bruteforce is practically impossible and takes years for a string of 8 charectors
I'm glad to find your comment. After doing some research here and there (a lot of googling) I came to the same conclusion as you. That means, if you are at home with your own private network (wireless or not) and you are visiting HTTPS sites, your traffic is already encripted. So if you only care about security (when doing online banking) and not about hiding your identity nor location, then a VPN is not necessary.
Well, I thought VPN stands for Vice President for Negotiation 😁(kidding)
Nice video as always.
Thanks
Just a note. Even if you pay for a vpn, they still may sell your data and i doubt that nordvpn don't log your activity.
Very true! , gain your trust then do as the free vpns do, sell your data 😚
Thanks for the awesome explanation.
