You may think a vpn and proxy are similar, because they have a similar end result: Hiding your IP address. But the way they do this is very different, and they cannot be used in the same way and by the same software. They are also very different in terms of security and encryption. This video goes over the difference between VPNs and different protocols used in proxy servers. By the end, you'll be well informed and know whether to use a vpn or proxy.

how's it going guys I'm Theo Joe and
today's video is actually based on a
question that one of you asked me it was
by a I dank Kai wanted to know what's
the difference between a VPN and a proxy
and I thought it was a really good
question because on the surface of them
they seem to be very similar they seem
to do the same thing which is hide your
IP address from websites and services
and change your IP address but that's
really where the similarities end they
are very different in terms of how they
work the protocols they support and in
terms of security and privacy and all
that sort of stuff so we're gonna go
over those differences and it is really
important to know this for those of you
who want a very basic explanation of
VPNs and proxies they basically both act
like a middleman so you establish a
connection with the proxy or VPN server
and then that kind of forwards your
request to the website so to the website
it looks like you're connecting from the
server and they don't see anything about
your real connection or location so
that's really the benefit of it but like
I said the way that this connection is
established is gonna be very different
between proxies and VPNs so the first
major difference is that with a VPN it's
configured at the system level so that
all traffic goes through the VPN
encrypted connection so it can you be
used with any traffic or any type of app
so you can use a VPN while you're
playing a game or streaming music or
doing file sharing anything like that
and although most VPN software's do
allow you to exclude certain apps for
the most part you're gonna be using a
VPN for all of your traffic at once with
a proxy server on the other hand that's
usually configured at the individual app
level so you would have to go into and
individual settings for some software
and put in the proxy connection settings
and then it would only connect through
that software well whereas everything
else will be unaffected
now the next major difference has to do
with security and spoiler VPNs in
general are going to be more secure than
a proxy so let me explain why with VPNs
they all pretty much work this
same way they're gonna all encrypt the
data put it in the tunnel and send it to
the VPN server and yes there are gonna
be different algorithms that you can use
to encrypt it in different key strengths
but they are going to all encrypt the
data now if you really wanted to you
could set up your own VPN server and
specially configure it to not use
encryption but you'd really have to go
out of your way to do that and really
anytime you would buy a VPN service and
use their software it's most likely not
gonna even have an option to disable
encryption so you're gonna get
encryption with a VPN that's the whole
point of it when it comes to proxies
though they aren't all the same there's
different protocols that a proxy could
use depending on the type of application
you're using a width and these different
protocols offer different levels of
security the first of these is going to
be an HTTP proxy this is basically just
going to be used for web content
obviously HTTP is the web protocol and
you're really not going to be able to
use this with any other type of data and
this might be either configured within
the browser itself so the web browser or
you might visit some website where
basically you type in the website you
want to go to and then it kind of
displays that as an interface so you're
not configuring the proxy it's just all
done on that site and the thing to know
about HTTP proxies is they're very
simple they offer no extra encryption at
all when connecting to the site even if
you're using it with your own browser
configured or again using one of those
proxy websites and this means that
anything you do on the web is going to
be just wide open as if you're just
using it with no proxy connection the
only thing it's doing is hiding your IP
address from the website another very
important thing to know is that some
HTTP proxies may or may not even allow
HTTP connections to web sites so you may
know that if you go to a web site and
you connect with HTTPS it says that in
the browser URL it means it's a secure
connection and an HTTP proxy may also
support HTTPS
which means it will be encrypted but it
may also just filter out all secure
connections in which case it'll either
just deny the
connection to the website at all if that
website forces secure connections or if
that website supports both it'll force
you into the non secure version of that
website so the advantage of these is
they might be a little bit faster
because there is no overhead but again
there's no encryption and a lot of free
proxies that do this type of protocol
will actually inject ads because it's
not encrypted so they can literally
modify your connection and inject ads
and that's how they monetize and that's
why they're free so always be a little
bit suspicious of free proxies the next
type of protocol is an HTTP proxy which
does actually encrypt everything with
the HTTP protocol so it's very similar
to the last one except it is encrypted
and if you connect to an HTTPS website
it's kind of like double encrypted
because again you're connecting to that
website with HTTPS and then the server
itself uses encryption as well the thing
to know is that if you connect through
to a website with HTTPS you're always
secure with that website because that is
a direct connection with you and the
website no matter what tunnel it goes
through they can't see anything and also
the other thing with HTTPS which I don't
like it's such a tongue twister to keep
saying this is that it does only support
web traffic typically so you're not
going to be able to use it with anything
else which is a little bit different
than the third protocol which I'm going
to talk about which is socks which is a
proxy that does support any type of
traffic so with a socks proxy and I
believe the most recent version is socks
five if an application supports it you
can use it so this could be music
streaming or voice chat or games or
anything like that but in terms of
security the socks protocol does not
offer any encryption by itself you would
have to have encryption built into the
app that would be connected with
whatever service it's using so I don't a
Skype or something
if white connects normally to the Skype
servers with a secure connection and you
use it with proxy it probably would
still be secure but it's not secure
because you're using a socks proxy if
that makes sense so if you're going to
configure a proxy with software and it
does
mention encryption anywhere you have to
assume that it's not going to be
providing its own encryption and is not
going to be secure
now many socks proxy servers do have ssh
support so it might allow an app to
connect with a secure connection but
that's only if the app supports it in
the first place just cuz again just
because you're connecting and through
the socks proxy doesn't mean it's secure
and also even if you are connecting with
SSH or something like that a lot of apps
will leak DNS so DNS that's basically
your computer sending out a request to
figure out what the IP address of a
domain is and it might send that request
outside of the proxy so even if you're
connecting with secure connection then
the operating system is still giving
away to your eyes P what you're using it
for and obviously another important
thing to remember is that even though
the socks proxy does support any type of
traffic the application that you want to
use it with has to support it in the
first place and for the most part most
popular software's really don't I mean
it's not really a huge request by most
people so you would have to use a VPN if
it doesn't support socks now all that
being said Windows itself does have a
settings page for configuring a proxy
which I assume would be used with the
whole system but again it doesn't
mention anything about encryption so you
really have to assume and I would assume
it doesn't offer any security in that
way so basically VPNs do have a lot more
advantages than a proxy the advantage of
a proxy is that it's gonna tip eclis
have less overhead because there's like
no security with it
so it might be faster if you really need
fast connection but again why would you
use a proxy in the first place if you
didn't want privacy and then it doesn't
really even offer privacy in the first
place and then again going back to VPNs
a big advantage with them is you can use
it with the whole system it does the
application doesn't have to support
proxies it doesn't even know that it's
using a VPN it's just all sent through
there like it's your regular connection
except it is encrypted really the only
situation I would consider where you
would want to use a proxy is like if
you're at school and you obviously can't
change the software settings on those
computers then maybe you could go to
like one of those web-based proxies and
you don't care about
see cuz you don't care about being
snooped on then you can use something
like that but again because it is gonna
be really not encrypted most likely I
wouldn't ever type any personal info
through a free proxy or especially not
login because again if it's not
encrypted or it's weak encryption or
something like that it's not gonna be
secure
so hopefully that covers everything and
answered a lot of questions you may have
had or may not even thought to ask and
if you guys enjoyed this video let me
know what you think down the comments is
there anything I didn't mention that you
want me to clarify I'll try to look at
those if you want to keep watching I'll
