Do I Need a VPN at Home?
When youuse a VPN,
you're adding a layer of protection to your online activities by
building an encrypted tunnel between your traffic and anyone who tries
to spy on you. VPNS are great for when you're out and about, using Wi-Fi
networks that aren't your own. But at home, a VPN can help protect you
from other threats and may let you access streaming content that would
be otherwise unavailable.
The Threats at Home
For the most part,
we can be assured that our home networks are safe. It's very unlikely
that a bad guy broke in, replaced your router, and then waited for the
good stuff to roll in. For one thing, that's just too much work. But for
another, attackers need more than one successful hit to make an attack
worthwhile. They'll want to rack up as much information from as many
victims as possible. Unless you live above an airport, it's unlikely
that there's enough foot traffic in your home to justify an attack.
But there are threats to consider when at home. The biggest one is from
the company that provides you access to the internet. The US Congress
hasallowed ISPs to sell data about usersand their online activities to
anyone interested. ISPs say that this information will be anonymized,
but the idea is still unnerving.
ISPs aren't the only ones
interested in what you're doing online. The fallout from the 2013
Snowden leaks has revealed that NSA surveillance isfar more pervasive
than previously believed. A VPN service makes it much harder for an
outside observer to correlate your online traffic to you.
VPNs Can Be Fun, Too
At leasthalf of all VPN useisn't for personal protection. It's for
streaming video. That might seem odd considering the negative effect
that VPNs have on your upload and download speeds, but it makes sense.
Not allstreaming video contentis available everywhere. Each streaming
service has a contract to carry shows and music that are sometimes
limited to specific areas. For example: If you want to watchStar Trek:
Discoveryin the US, you need to have aCBS All Accesssubscription. If
you live outside the US, you can watch it on Netflix. Personally, I pay
forStar Trek, but I digress.
That's where VPNs come in. You can use
your VPN to tunnel to a distant server and access content that is
restricted in your home country. WhileNetflix is very good at blocking
VPNs, this trick is also useful for sports fans. Sometimes the best
games aren't available for US audiences, or the US coverage is so
annoying that die-hard fans would rather see how the BBC or CBC handles
the games.
Trouble at Home
VPNs are all about securing your
traffic from prying eyes, and that's sometimes a problem when you want
your traffic to be seen. If you live in an especially smart home, you're
likely to encounter some problems with using a VPN.
A great example
is Chromecast, Google's dead-simple method for getting content from
your phone or computer on to your TV. When you try to use Chromecast
with a VPN, all your data is shuffled off your devices through an
encrypted tunnel, and can't reach other devices on your local network.
You'll have to switch off your VPN if you want to use this feature, or
others like it.
One solution to this problem is to simply raise the
level of your VPN and install it on your router. That way, all the data
on your local network is funneled through the VPN, giving you all the
protection without causing any of the fuss on the local level.
Configuring your router to use a VPN can sound daunting, but some VPN
companies will sell you a pre-configured router if you want to give it a
try. Still, I think this solution isnot for everyoneand perhaps best
left to people with a determined DIY sensibility.
While many people
are using VPNs to stream online content, many (if not most) streaming
services are very good at blocking VPN usage. One possible solution is
purchasing a static IP address from your VPN provider. These "clean"
addresses aren't associated with VPNs, giving you a better chance of
slipping past attempts to block your access.
Speed will always be an
issue with VPNs. When a VPN connection is active, your web traffic is
going through more machines and more fiber. The result is increased
latency and slower transfer speeds. Not all VPNs are the same in how
much they affect your connection, but you will see some impact.
Do You Need a VPN at Home?
In truth, the answer to the question of whether you "need" a VPN in
your house is going to come down to your own preferences. There are lots
of good reasons why a home VPN might be a valuable addition to your
security arsenal, but what's most important is whether you will use it.
If you find yourself too frustrated with reduced internet speeds, or
juggling streaming devices, don't use a VPN at home. An unused security
feature isn't useful to anyone.
Speaking personally, the decision by
Congress that allows ISPs to sell anonymized data about their customers
is a huge motivator. It's why I keep my VPN switched on as often as
possible, even at home. But I do switch it off when I need to cast
content to my TV. Security is important, but so isStar Trek.
