Today there are major fears of cyber-crime. Identity theft is at an all-time high with corporate intellectual theft following the trend.
Governments and businesses have taken action by restricting access to those under their umbrella. While they mean well, this isn’t always a good thing.
This restriction isn’t always solely for security purposes. Corporations and governments can and have restricted access to information about things that threaten their sovereignty, expose their wrongdoings or simply rival their power or influence.
I personally value national security, but it’s nice to be able to watch the Olympics or Netflix where I want to or browse for news relevant to me and to that end we have VPNs or Virtual Private Networks.
A Virtual Private Network is a service that connects you to the internet through a specific server. This server encrypts your information allowing you to have a level of privacy and security that isn’t otherwise possible.
Designed for Corporate
VPNs were originally developed to enable corporate workers to securely access their networks from anywhere in the work. This is referred to as a corporate VPN. While this use is still in place chances are most times you’ll here about this service it’ll be referring to commercial VPNs.
Why Would I Need One
You may be wondering why that matters if you aren’t planning to do anything illegal so here are some examples –
- You’re on holiday and you’d like to catch the season finale of ‘insert show here’ but it isn’t available for viewing in your host country.
- You’re at school or work and you’re blocked from the website you need to get the information you require.
- You’re using public internet and aren’t interesting in being an easy target for hackers.
Those are the most relatable examples, but there are far more uses. While there are nefarious uses for a VPN the vast majority of users simply want privacy. Thus, there’s no stigma for their use in most countries.
Nuts & Bolts
When you access the internet you connect to your internet service provider (ISP). From there, you connect to any websites you choose to visit. Everything you do from the point you connect to your ISP can be viewed (tracked) by them assuming you allow it.
When you connect via an VPN you still go through your ISP, but now your data is encrypted. The ISP is aware that you’re connected to and using the internet, but not where you are specifically unless you’ve designated so on your VPN.
The Downside of Using a VPN
Nothing is perfect and the cost of encrypting and decrypting all the data you access is processing power. You’re browsing experience will be slowed when using a VPN. The stronger the encryption, the greater the power needed, the slower the experience.
This is compounded by the distance traveled to the VPN server of your choice. If you live in South East Asia a server in the UK will yield faster results than a server in the US due to proximity.
Before you go out to get a VPN do a little research and check some reviews. There’s tons of information out there. Cheers and stay secure out there.
