What is a VPN, and how does it work?
VPN is a secure connection between your computer and a server. Without a VPN, your personal information might be expose to third parties whenever you are visiting a website, streaming online video or even download files from a trusted site.
With VPN, when you connect to the internet, VPN acts as a middleman by encrypting your traffic through their secure server, so neither your ISP nor any third party will not able to see any of your online activities. So basically, using a VPN is adding more layers of protection to your online activities.
Why do we need it?
In today’s world, the internet is being a mandatory need in every aspect of our life, being convenient does have its cost, due to privacy, and security.
Almost all of our works are done on our personal computer, either freelance work or accessing company networks from our home or public network.
From the security side, on open connection without VPN could expose some threats like sniffing what we do on the internet and accessing vital information like credentials.
We are being tracked and logged by ISP and websites. They will able to see any of our activities and could sell our data 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 your online activities, your govt more likely also does. With a VPN, it is much harder for any outside observer to correlate our online activities with us.
The perk of using VPN
• Access a Business Network While on the go:
VPNs are frequently used by travelers to access their business’ network, including all its local network resources, while on the road. The local resources don’t have to be exposed directly to the internet, which increases security.
• Hide Browsing Activity From Local Network and ISP:
If we’re using a public Wi-Fi connection, your browsing activity on non-HTTPS websites is visible to everyone nearby, if they know how to look. If we want to hide our browsing activity for a bit more privacy, we can connect to a VPN. The local network will only see a single, secure VPN connection. All the other traffic will travel over the VPN connection.
• Access Geo-Blocked Websites and services:
Whether we’re trying to access Netflix account while traveling out of the country or wish you could use American media sites like Netflix, Pandora, and Hulu, we’ll be able to access these region-restricted services if we connect to a VPN located in the USA.
• Bypass Internet Censorship:
Many people use VPNs to get around the internet limitation by govt firewall to gain access to the full internet world outside.
• Downloading Files:
Many people use VPN connections to download files via torrent. VPN can be useful even if we’re downloading completely legal torrents – if our ISP is throttling the torrent site and making it extremely slow, we can use the torrent client on a VPN to get faster speeds. The same is true for other types of traffic that our ISP might interfere with (unless they interfere with VPN traffic itself.
So do we need a VPN?
The answer to whether we “need” a VPN depends on your preferences. There are lots of good reasons why a VPN might be a valuable addition to our security.
Personally, the decision that allows ISPs to sell anonymized data about their customers is a huge motivator. I keep my VPN switched on as often as possible, even at home, and especially when I am outside.
