what is wireguard and do you actually need it
the key goal of any vpn provider is to create a secure encrypted tunnel for
all your internet traffic shielding it from hackers and other third parties like icp that
want to take a peek vpn providers can choose from many security protocols such as openvpn ikev2 l2tb
ssdp and others to create and manage that tunnel each with their advantages and disadvantages
say openvpn is the most popular option but its design dates back to 2001 and much has changed
in our technologies and years in the last 20 years wireguard on the other hand is a more recent entry
into the world of vpn protocols and has already gained a popularity among cyber security space
one major advantage of a wireguard protocol is its simplicity whilst openvpn and say
ikev2 requires hundreds of thousands lines of code buyerguard only requires about 5 000.
and that has all sorts of benefits for example fewer bugs and security and reduced cpu usage
as a result faster connection and by the way it's much better suited for mobile devices and
routers that don't have desktop levels of computer power cryptography is another highlight because
fireguard uses state-of-the-art protocols such as curve25519 chacha 20 poly1305
and blake 2 and some others it doesn't really matter what matters though is that you hit
the like button to show me that you like this type of video and if that is done let's proceed
nobody is wireguard doesn't have a way to allocate dynamic ip addresses for
instance this means in theory that your vpn ip address might be the same each time as you log
in thus perhaps allowing to track you online wireguard doesn't automatically delete your ib
address when you disconnect either and it might stay in memory for who knows how long after your
session has ended like openvpn and some other protocols work harder on your privacy by deleting
the ip addresses that are no longer needed thus reducing the opportunity of your address to be
logged also wireguard doesn't have such thing as a forward secrecy a system where vpn data
is encrypted each time with a new key wireguard just uses the same key by default
which means if a hacker gets into the system and steals the key they can decrypt your traffic
although wireguard does have some privacy concerns they are not issues or bugs with the design
the whole point of this protocol is to keep things simple and throw away a lot of complexity so
these are the features that got left out however the speed is nice and this speed is
a major advantage of a wire guard protocol it has a light touch when consuming your
device cpu resources and it is a linear protocol overall which basically means a longer battery
life and less lags when you open and reopen other apps on your device the speed boost also includes
connection and reconnection speeds when you're using your vpn that uses availaguard protocol
say on your mobile device when you reconnect from your mobile data to wifi if you are using
a wireguard protocol you probably won't even notice this reconnection time and the loss of
your connection speaking about connection let's connect here on youtube so that you don't miss our
new episodes hit the subscribe and the bell icon right next and if that is settled let's proceed
for maximum privacy stick with openvpn especially if you are under a jurisdiction whereby passing
censorship is important however if you are using a vpn in an environment where speed
is a priority over privacy say accessing international service of video streaming
while in the area with a lower speed connection you might want to switch from openvpn to
wireguard so if you want to try wireguard protocol here are some of the vpns that support wireguard
northvpn surfshark and express vpn let's start with sur shark to switch to wire guard protocol go
to settings advanced and here is a protocol that you can choose by default i put automatic but you
can switch to wireguard protocol as to expressvpn you go straight into the options and here you can
see a tab protocol and while expressvpn doesn't support wireguard it supports lightweight
protocol which many believe is better than vargard and uses the same principles as vargardt
does i have linked all of those below with the best pricing offering that you won't find
anywhere else on the web before you go though make sure to hit all the buttons you find below and
let me know what you value the most in vpn providers is your priority speed or privacy
let me know in the comments and i'll be waiting for you in our next episode see you there bye
