How A VPN Can Boost Your Online Security & Privacy
In layman’s terms, a VPN (virtual private network) is used to secure your entire web session, which includes transmitted data, personal information, financial transactions, online traffic, and many other segments of your online presence, which are all appealing to hackers, governments, and marketers.
In order to do that, VPNs have to encrypt your online traffic. You can view encryption as a strongbox of sorts used to store your information. Every strongbox has a lock, so this is where encryption keys come into play. When you see letters and numbers like AES-128 or AES-256, the number indicates the number of bits in your security key. Naturally, the higher the number, the harder it is to “pick” your encryption lock without a key.
Modern cryptology has gone a step further in optimizing your online security with perfect forward secrecy, generating a random secret key per session. In other words, every time you connect to your VPN, the lock on your “strongbox” will have a different key. This ensures that, even if one session gets compromised, the attacker can’t compromise others as well, which makes the acquisition of any past encryption keys rather useless.
Finally, VPNs also obfuscate your real IP and consequently, your real identity and location. VPN providers usually give you a shared IP address used across multiple connections, which lowers the chances of anybody “recognizing” you online and identifying you as an individual. Some of the safest VPNs also offer dedicated IPs, which never change and are more difficult to be recognized and blacklisted by services such as Netflix.
Free VPNs – A Good Idea Or A Security Risk?
Running a VPN service is very expensive. Setting up powerful servers that work non-stop, writing software that allows you to route connections through those servers, and employing skilled individuals to maintain and keep the servers running are just some of the essential parts of operating a VPN service; not to mention the huge bandwidth cost that increases as the number of users goes up.
With that in mind, companies that offer free VPN services have to get their funding someplace else, which brings us to the main problem with free VPNs – if you’re not paying for something, you are the product. In other words, if you’re not paying with money, you’ll be “paying” with your personal information.
Many of the low-quality VPN providers actively seek to exploit you in some way in order to maintain their “free” business model. They can utilize you as a P2P endpoint (or node) and use your bandwidth to support other customers. Alternatively, they can actively “steal” your data and sell it to third parties. As you probably know already, all the big companies like Google or Facebook are “gunning” for your personal info, which they can later sell to advertisers.
Having said that, the prefix “free” has become something of a red flag when it comes to VPNs. If you absolutely cannot afford a paid VPN, we recommend going with free plans offered by reputable providers. They are financed by profits made from premium options, so the companies have no reason to exploit you in order to sustain themselves. Note that these options are somewhat limited in terms of servers, P2P traffic, simultaneous connections available, and other features reserved for paid plans.
Choosing The Safest VPN
Contrary to popular belief, online security and privacy are not the same things. You should keep this in mind when choosing the safest VPN service for your particular needs and preferences. Different VPN providers offer different levels of technical security, ranging from impressive to subpar and inadequate. That is why it is important to know exactly what to look for in a VPN before any money changes hands.
Let’s take a look at what makes a safe VPN:
When you see a VPN company mentioning “military-grade” or “bank-grade” encryption, they refer to AES-256 cipher, which is currently the strongest encryption. It represents an unbreakable barrier between your online data and all sorts of prying eyes looking to interfere with your connection.
Some companies feature AES-128, which only means they use 128-bit keys to encrypt your traffic. Some will say this is a lower level of security, but today’s computers cannot break AES-128 – and your encryption can’t get any better than unbreakable.
This cipher is usually paired with RSA-2048 handshake and SHA-256 authentication, which is an optimal security configuration, according to modern standards. Some companies use RSA-4096 and SHA-512, but they are not really necessary.
Reliable Connection Protocols
When it comes to connection protocols, we wholeheartedly recommend going with a provider that supports OpenVPN. Its inherent encryption offers an optimal level of online security and can protect you from hackers coming from criminal circles, as well as your government.
Keeping this in mind, let’s go over the pros and cons of the most popular connection protocols used by some of the safest VPNs:
|PROs||Can bypass most firewalls, highly configurable, open source, highly secure, compatible with numerous encryption algorithms|
|CONs||Tricky to set up, requires third-party software, needs better support for mobile devices|
|PROs||Fast, easy to set up|
|CONs||Outdated, compromised by the NSA|
|PROs||Usually considered secure, easy to set up, available on all modern operating systems and devices|
|CONs||Most likely compromised by the NSA, slower than OpenVPN, problematic with restrictive firewalls, deliberately weakened by the NSA|
|PROs||Can bypass most firewalls, usually secure (depending on the cipher)|
|CONs||Only works on Windows platforms, Microsoft’s proprietary standard|
|PROs||Very secure, supports numerous ciphers, stable, easy to set up, faster than SSTP, L2TP, and PPTP, supports Blackberry devices|
|CONs||Uses the easily blocked UDP port 500, not open source, tricky implementation at the server end, limited platform support|
OpenVPN is definitely the safest but not the fastest connection protocol. If you’re willing to sacrifice security for speed, you can choose PPTP, for example. PPTP is faster than OpenVPN and just as easy to set up as L2TP, but they are both compromised by the NSA. PPTP is easily blocked and L2TP is often implemented badly and can struggle with restrictive firewalls. L2TP with IPsec authentication (L2TP/IPsec) is usually poorly implemented and uses pre-shared keys. SSTP protocol is pretty secure and can bypass most firewalls but is entirely owned by Microsoft, which brings a whole slew of limitations.
A VPN/Internet kill switch is designed to prevent accidental exposure of your true IP address in case your VPN disconnects for whatever reason. It is just a simple feature written into the software of your chosen VPN created with the purpose of killing your Internet connection if your VPN fails.
If you disable this feature, once your VPN disconnects, your computer will automatically re-establish a regular connection through your ISP and expose your true location to all protocols and websites you are browsing at that moment.
You can view the kill switch as a tripwire that constantly monitors your connection for any IP or status changes. If it detects anything out of the ordinary (like a VPN connection drop), it’ll block your computer’s Internet connection until your VPN comes back online. The software reacts instantly and will never allow your computer to connect to the Internet outside of your safe VPN tunnel.
Protection Against DNS/IP Leaks
First of all, let’s explain the terms “DNS” and “IP” and then we can deal with their respective leak prevention.
DNS stands for “Domain Name System” and represents a framework used by machines with Internet-connecting capabilities to translate domain names into numeric values that machines can “understand” and process.
In other words, thevpnlab.com is the site’s domain name and it allows people to find it on the Internet. This domain name is translated into a numeric form known as an IP (Internet protocol) address, which is required for machines to locate resources online. The job of your Internet service provider is to facilitate this translation.
DNS is basically a database filled with domain names, something like the great phone book of the Internet.
One of the core functionalities of every VPN lies in obfuscating your real IP address while assigning you with a fake one from the region of your choice, although some VPNs do not provide their users with regional IPs.
If your VPN of choice allows your real IP address to “leak out,” it defeats the very purpose of having a VPN in the first place. IP leaks are also known as WebRTC leaks (WebRTC is a framework designed to facilitate online communication). With DNS leaks, your computer will contact your ISP for DNS service instead of your VPN, which is a big no-no if you want to remain anonymous online.
Everything we mentioned so far has been about preserving your online security. A strict no-logging policy is there to ensure your privacy is protected as well.
Only a no-logging policy can prevent your VPN provider from simply handing your data over when requested to do so by a government agency or similar organizations with public authority.
If your chosen company doesn’t keep any logs, it will have no data to hand over – it’s as simple as that. In order to make sure you’re completely protected, it’s a good idea to choose a VPN provider registered in a country without any mandatory data retention laws.
VPN providers can keep two types of logs:
- Connection logs – Your IP address, IP address assigned by your VPN, time stamps (start/end of your VPN sessions + duration), amount of data transferred during each session
- Usage logs – Downloaded files, list of visited websites, protocols/software (Netflix, BitTorrent…)
As you can see, usage logs are much more invasive and dangerous and you should definitely avoid VPN services that keep these logs, no matter how cheap they are.
In order to ensure optimal security and privacy while online, you also have to pay attention to the geographic location of your chosen VPN provider.
Many VPN services are registered in countries with implemented mandatory data retention laws. This means they HAVE to log your personal information and hand it over if requested to do so by the government or some of its agencies. These countries include Italy, Latvia, Malta, Portugal, France, Greece, Estonia, Austria, and others.
Furthermore, you should also pick a VPN service registered outside of the Five Eyes Alliance, which includes the US, New Zealand, Canada, Australia, and the UK. The reported close partners of the Five Eyes Alliance include Israel, British territories overseas, South Korea, Japan, and Singapore.
The Nine Eyes countries include the Five Eyes members, plus France, Denmark, Norway, and the Netherlands. The 14 Eyes treaty also includes Belgium, Germany, Sweden, Italy, and Spain.
Apart from numerous surveillance treaties launched to spy on their citizens, countries like the US, for example, have a pretty extensive legislation that allows the government to obtain information from your VPN provider without you even knowing it.
If you decide to go with a VPN service located in a country with unfavorable legislation, at least make sure the country doesn’t have mandatory data retention laws. Additionally, if a VPN is based in one of the ”Eye countries,” make sure it has a strict zero-logging policy.
