      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?

    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.

      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.

    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.

    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.

    With the help of this video, I understood in around 7 minutes what is VPN (Virtual Private Network) in detail. I find VPN pretty useful tool to hide the identity if needed and to encapsulate the data sent over the internet. Also, if a person works from home VPN could be very useful to connect to the main office in a safe and secure way. Thus, VPN especially nowadays could help many to have a secure network.

      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.

      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.

    Generally, proxies offer quicker connectivity than VPNs because they route only specific types of traffic, while VPNs encrypt all internet traffic, potentially causing delays. Zeus Proxy excels with its rotating residential proxy, perfectly suited for activities like e-commerce multi-account registrations, data crawling, airdrops, and gaming.

    @1:09 "By using a VPN, your on-line activity will bypass your ISP's server, and will be redirected to another server, which is a VPN server.".
    Well, sort of, but...
    You are not bypassing your ISP's server.
    100% of your internet activity is still going through your ISP's server.
    The difference is that your ISP's server can no longer see what you are doing, even though 100% of your data is passing through their server.
    This is because your data is being encrypted on your local computer, and gets decrypted by your VPN's server. Any and all computers between you and your VPN service will only pass along the encrypted data, and will not be able to see anything other than scrambled data.
    @3:07 "So any activity that you do on the internet, such as visiting web pages, or transferring files -- the data is encrypted, and kept private, when using a VPN".
    Your data is encrypted, only between you and the VPN's server. Once you data reaches your VPN's server, 100% of your data is decrypted by your VPN service. The VPN service can see 100% of your activity, in the clear.
    So your data is not kept private, when using a VPN service. You are trusting your VPN service to do the same thing as what your ISP does. By using a VPN service... all of your internet activity will stop being visible by your ISP, and will now be visible by your VPN. You have simply handed your trust to a different company -- a different group of complete strangers.
    @5:34 "It reassures that you are surfing the internet safely, securely, and anonymously".
    If you visit sketchy sites, a VPN service will do zero to protect you. You will encounter malware, viruses, etc, the same as if you were not using a VPN service. The VPN service is simply acting as a middle-man. The VPN service does not interfere with what you are doing. The VPN service will pass along anything and everything, including malicious data.
    As to "anonymously", that is true, only if your VPN service is telling the truth.
    Lots of VPN services claim a "No logs" policy.
    They can claim anything that they want, because you have zero ways to verify their claims. They could be logging everything that you do, and you will not know, and you can not know.
    And even if a VPN service really abides by their claim to keep no logs...
    If they are handed a court order to keep logs, then they are going to keep logs. And if they are also handed a gag order, then they will not be allowed to reveal that they are keeping logs.
    What better place for governments to spy on people, than via VPN services?
    Using a VPN service is announcing that you really, really, really, want to keep your on-line activity private. That is where governments really, really, really, want to see what you are trying to keep private.
    If you think that your VPN service is really keeping your on-line activity private, you will have a rude awakening if you use a VPN service and engage in illegal porn distribution, or if you post that you are going to commit violent crimes (the type that puts you behind bars for life), etc. Watch how quickly you will get a visit from a government agency.
    @6:33 "But paid VPNs are more secure. These, generally ,will not log your internet activity, and they will keep it private".
    @6:49 "...and they have a strict, 'No logging' policy".
    As I wrote about above... you have zero ways to verify any VPN's claims.
    Also note that many countries have reciprocal law enforcement agreements.
    So if country "A" asks country "B" to keep logs, then they will comply. That goes for court orders.
    Look up "five eyes" and "fourteen eyes". Each set of eyes refers to countries that cooperate with one-another.
    Use a VPN service for accessing services that your county does not permit, or in a coffee shop on public WiFi, or to connect to your office.
    For all of those uses, a VPN should be safe and secure. But for general internet activity, using a VPN service is putting all of your eggs in the VPN's basket, instead of your ISP's basket.
    I am dismayed that our host made VPNs sound like the holy grail of security and privacy. They are not, and he knows it.
    If you want that level of privacy and security, then use TOR browser via the TAILS operating system, or via ParrotOS and its Anon Surf feature, or via Qubes OS, and one of its TOR related virtual machines.

Is it using a vpn? And using their server or perhaps doing that and then adding the static ip address that NordVPN offers? Or is it by setting up my own vpn server in a location where I want my ip address to be giving that location from and connecting to that? Can you give me a clue. It would be for work, and know the laws and I know I should let my employer know. I know the ethics of it in other words. But can you help me on it, some serves will block access if they detected a common sever right? Can a vpn use to access an employer vpn? Its is all in the router? Asus rog ax5400 to?

    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?

      @@emmanuelobareki4655 let me refrase. Whenever someone visits a HTTP (NON-HTTPS) website throught a VPN, data is still going unencrypted between VPN server and website. Advertisers, ISP's (yes, VPN providers also use ISP services to have an Internet access) and governments can still read that data, despite NOT knowing whose data it is. Encrypted (HTTPS) web site - only site name can be read from DNS requests (unless DNS over TLS is used) or trafic to the site itself (unless encrypted SNI is used). Advertisers, hackers or governments only have site name and user ip (or VPN server IP if used)

  • @blcjck8121
    @blcjck8121 ปีที่แล้ว +3

    Most home users do not have a unique public IPv4 address assigned to them, because of shortage. Instead most ISP's set up a CGN to share public IP's between many customers, which means users can not be identified by public IP.
    Also a VPN does not provide anonymity as there are many other ways to identify users other than IP. The VPN provider could also intercept your data if they wish, so it all comes down to who you trust. There's nothing to generally indicate, that just because they are a paid service they can be trusted or does not log activity.

    3:19 This is a persistent lie told in just about every advertisement for a VPN. I have to disable my VPN to watch a video on Netflix. I live in the US and use a VPN in the US. Netflix knows I am trying to watch a video from a VPN server that is in the US but they don't know where in the world I am, so they disallow it.

      Netflix does blacklist. Not just Netflix many ott tv stations which do geoip identification also implement blacklists. One example is Abema TV, a Japan ott tv station. They put all data centre IPs into a blacklist. You need a sock5 proxy with residential IPs.

    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

    Most websites support HTTPS, a hacker or ISP can only see you're visiting the domain not the full URL, they also can't change the pages. When dns over tls become supported there will be no need of using a VPN when it come to security (security of visiting websites over https, other protocols will still be vulnerable). You can safely check your favorite social media website on public wifi. The only benefit of a VPN for me is restricted geographical content.

If it's server based (e.g LOL, DOTA, APEX, PUBG, Fortnite...) then only the company will know your IP, a VPN in this case is useless.

      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.
