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.

I’ve watched dozens of your videos since discovering your channel a few days ago. Your ability to simply explain complex technologies is amazing.❤

[Someone-bfru]

I'm never as excited to learn as I am whenever you upload a new video. Greatest explanations ever!

[augustemaillot]

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

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

[priceg.t]

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 😌

[Working]

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

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.

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.

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!!

[ranjanadissanayaka]

hey, thanks for making this video...I've been following your videos for sometime. I'm now watching them as you post them.😀

[Soundwave]

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!

[jozsefjuhasz]

These videos are gold ! Keep going and thank you so much for making them!

[dimitrijedukovski]

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) ...

[repsrandom]

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.

[maniagonewild]

Love your Channel! Thank you for creating helpful and straight forward videos.

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.
