One pet peeve I have is that everyone who is less tech savvy thinks that vpns hide all your info from everyone. They get this from CZcams ads and even my old uncle has asked me about it because he hears ads on the radio saying that this product can stop hackers and stuff. All the advertising is very misleading to people who don't understand what the purpose of the product is. Great video as always :)
A VPN encrypts, the most important part, all your outgoing data, and not just browser activities.
You won't get this safetylevel with proxyservers, since the won't provide any additional encryption, besides the
standard SSL/TLS encryption. (and stripping this, isn't a problem for any 3 letter agency)
So, a proxy will always be more vulnerable than a VPN.
I absolutely agree with the fact, that it is really important to choose your proxy- or VPNprovider wisely, because all you do: is shifting your trust from your own ISP, to them. And many companies out there will, sadly enough, answer trust with betrayal.
The P in VPN stands for Privacy, and not for anonimity, this is somewhat confusing for most people. And the big providers love to play with this fact, by providing a false sense of safety and anonymity in there commercials, knowing all to well that privacy and anonimity depends on so much more, than only securing the datatransport.
Great feedback! One thing I forgot to mention is I only use (and therefore recommend) SOCKS v5 over SSH proxies (which support proxying DNS) so the encryption level is similar to using a VPN thanks to SSH tunneling. That being said, you are absolutely right about VPNs encrypting all traffic (when well configured) vs proxies that tend to only apply to browsing. That false sense of safety and anonymity is unethical. Anyhow, thanks for sharing!
@@sunknudsen hey Sun, thanks for your answer.
I do agree that socks5 is more secure, given the fact the authentication now is in play, always a good thing. But it still doesn't provide the same level of security, provided by VPN. Because, for the most part, the data still isn't additional encrypted, other than the access to the socks5 proxyserver.
> Because, for the most part, the data still isn't additional encrypted, other than the access to the socks5 proxyserver.
What do you mean? In the context of browsing (say we configure a SOCKS v5 over SSH proxy in Firefox), SSH handles authentication and encryption as the SSH tunnel is encrypted. SSH also implements public key cryptography (using Diffie-Hellman key exchange) and forward secrecy.
My gut feeling is that level of encryption compares to most VPN implementations.
For the record, I would still recommend always using a trustworthy VPN (I self-host my own) and running the proxy through the VPN for additional privacy. All of this will be the subject of future episodes. 🤓
@@sunknudsen Hi Sun, thanks for your great response, I'm a bit late responding (I'm in a different timezone 😉)
I agree with you that when we talk about browsing, a socks5 proxy/SSH will indeed provide almost the same level of security and anonimity. (but its still lacks its own encryption, an extra safeguard agains snooping)
I still prefer though, like you also said, a VPN, given the fact that a VPN works on the systemlayer, and handles all your data, instead of SSH, that's on the applicationlayer. That combined with the strong encryption it provides(stacked layers of security/privacy and network options) makes it my preferred choice.
Both options serve different purposes, but share a lot of similarities. In the end, it all depends on your needs and wishes.
So, now I'm going to enjoy one of your other video's 👍
i would love to see a case study on nord vpn!!
Zeus Proxy offers various proxy solutions, including rotating residential proxies, which have caught my attention for their diversity and exceptional quality.
Can you do a video about dVPNs? Orchid, Mysterium, Deeper...
Great info & explanations. Please do a video on how to configure proxies on Firefox in order to run multiple Facebook profiles through the one browser (I’m in advertising).
Thanks for the feedback. I'm currently backlogged but that episode is on the top of the list.
Sun Knudsen Fantastic, I look forward to tuning in.
Firefox, while being used with some VPNs, can leak user's IP address. I ran a DNS leak test with Brave browser + Proton VPN (free plan) and saw no IP leaks. I wonder if there's a way to fix that problem on Firefox.
Hey, have you watched czcams.com/video/NH4DdXC0RFw/video.html and czcams.com/video/uYoJ7U0OMCY/video.html
@@sunknudsen Thanks for responding to my question. I have watched both videos (amazing work btw). Apparently, the "enable DNS over HTTPS" setting on Firefox is the reason for the problem. I turned it off, ran the DNS leak test again (Firefox + Proton VPN) and no IP leaks this time. Restore Privacy has a explanation on why disabling DoH is a good idea while using a VPN service. restoreprivacy.com/firefox-privacy/
Interesting... thanks for sharing. Strange how DoH would leak our IP... what website did you use to test for leaks and which VPN protocol were you using?
@@sunknudsen "DNS leak test" was the website I used to test for leaks. www.dnsleaktest.com/ and the VPN protocol was IKEv2/IPSec (ProtonVPN).
@@NoWay2SeeTheirHoax I'm still kinda new to these sort of things, but from my understanding, isn't the VPN the one leaking the DNS/ IP and not the browser itself?
So, let's say I use a VPN provider that is out of the US. PIA as an example. If I were to connect to a Switzerland VPN server with PIA, is my traffic "under" (for lack of a better term) Swiss privacy laws, or is it under US laws because it's a US service?
Great question, I am not a lawyer, but my gut feeling would be not using a service provider incorporated in a country with poor privacy legislation.
Its the last. Every company that has a office in the US, falls automatically under US laws.
whooo more please lol
Hey Sun → can you please make a video about the best way to BLOCK PORN? OpenDNS ? Something else?
when you say "use Tor for very sensitive stuff", you mean: use Tor for porn?
I am not worried about porn... no need for a VPN or Tor for that in Canada. The technology division of PornHub is headquartered not to far away from where I live.
