With growing censorship and regulations threatening global internet freedom and security, in turn, we’ve seen an increasing number of services become available to protect your online web browsing.
Virtual Private Networks (or VPNs) have become increasingly popular in recent years for their ability to bypass government censorship and geo-blocked websites and services, and do so without giving away who is doing the bypassing.
For a VPN to do this, it creates what is known as a tunnel between you and the internet, encrypting your internet connection and stopping ISPs, hackers, and even the government from nosing through your browsing activity.
We explain the basics of what a VPN is here
What is a VPN Tunnel?
When you connect to the internet with a VPN, the VPN creates a connection between you and the internet that surrounds your internet data like a tunnel, encrypting the data packets your device sends.
While technically created by a VPN, the tunnel on its own can’t be considered private unless it’s accompanied with encryption strong enough to prevent governments or ISPs from intercepting and reading your internet activity.
The level of encryption the VPN tunnel has depends on the type of tunneling protocol used to encapsulate and encrypt the data going to and from your device and the internet.
Types of VPN tunneling protocols
There are many types of VPN tunneling protocols that offer varying levels of security and other features. The most commonly used tunneling protocols in the VPN industry are PPTP, L2TP/IPSec, SSTP, and OpenVPN. Let’s take a closer look at them.
Point to Point Tunneling Protocol (PPTP) is one of the oldest protocols still being used by VPNs today. Developed by Microsoft and released with Windows 95, PPTP encrypts your data in packets and sends them through a tunnel it creates over your network connection.
PPTP is one of the easiest protocols to configure, requiring only a username, password, and server address to connect to the server. It’s one of the fastest VPN protocols because of its low encryption level.
While it boasts fast connection speeds, the low level of encryption makes PPTP one of the least secure protocols you can use to protect your data. With known vulnerabilities dating as far back as 1998, and the absence of strong encryption, you’ll want to avoid using this protocol if you need solid online security and anonymity – government agencies and authorities like the NSA have been able to compromise the protocol’s encryption.
Layer 2 Tunneling Protocol (L2TP) is used in conjunction with Internet Protocol Security (IPSec) to create a more secure tunneling protocol than PPTP. L2TP encapsulates the data, but isn’t adequately encrypted until IPSec wraps the data again with its own encryption to create two layers of encryption, securing the confidentiality of the data packets going through the tunnel.
L2TP/IPSec provides AES-256 bit encryption, one of the most advanced encryption standards that can be implemented. This double encapsulation does, however, make it a little slower than PPTP. It can also struggle with bypassing restrictive firewalls because it uses fixed ports, making VPN connections with L2TP easier to block. L2TP/IPSec is nonetheless a very popular protocol given the high level of security it provides.
Secure Socket Tunneling Protocol, named for its ability to transport internet data through the Secure Sockets Layer or SSL, is supported natively on Windows, making it easy for Windows users to set up this particular protocol. SSL makes internet data going through SSTP very secure, and because the port it uses isn’t fixed, it is less likely to struggle with firewalls than L2TP.
SSL is also used in conjunction with Transport Layer Security (TLS) on your web browsers to add a layer to the site you’re visiting to create a secure connection with your device. You can see this implemented whenever the website you visit starts with ‘https’ instead of ‘http’.
As a Windows-based tunneling protocol, SSTP is not available on any other operating system, and hasn’t been independently audited for potential backdoors built into the protocol.
Saving the best for last, we have OpenVPN, a relatively recent open source tunneling protocol that uses AES 256-bit encryption to protect data packets. Because the protocol is open source, the code is vetted thoroughly and regularly by the security community, who are constantly looking for potential security flaws.
The protocol is configurable on Windows, Mac, Android, and iOS, although third-party software is required to set up the protocol, and the protocol can be hard to configure. After configuration, however, OpenVPN provides a strong and wide range of cryptographic algorithms that will allow users to keep their internet data secure and to even bypass firewalls at fast connection speeds.
Which tunneling protocol should I use?
Even though it’s the fastest, you should steer clear of PPTP if you want to keep your internet data secure. L2TP/IPSec provides 256-bit encryption but is slower and struggles with firewalls given its fixed ports. SSTP, while very secure, is only available on Windows, and closed off from security checks for built-in backdoors.
OpenVPN, with its open source code, strong encryption, and ability to bypass firewalls, is the best tunneling protocol to keep your internet data secure. While it requires third-party software that isn’t available on all operating systems, for the most secure VPN connection to the internet, you’ll want to use the OpenVPN protocol.
A good VPN service should offer you the choice of at least these four types of tunneling protocols when going online. We’ve compiled a list of the best VPNs in the industry for you to get started on protecting your internet data.

Samsung to invest $115 billion in its foundry business by 2030
Samsung is earmarking $9.5 billion a year for Samsung LSI and Samsung Foundry.
Samsung Electronics is one of the largest semiconductor players around, and the manufacturer is investing $115 billion (133 trillion won) over the next 12 years to take on Qualcomm and Intel. Samsung says its goal is to become the world leader in semiconductors and logic chips, and the company will invest $9.5 billion a year from now through 2030.
Samsung will invest $63.4 billion (73 trillion won) toward domestic R&D — where it is looking to add 15,000 jobs to “bolster its technological prowess” — and spend $52 billion (60 trillion won) toward production facilities that will make the logic chips. Samsung has long been the dominant player in the memory business, but with that market shrinking the South Korean manufacturer will be looking to diversify.
While the $115 billion seems like a staggering amount at first, it’s in line with what Samsung has been spending in recent years. Just last year alone Samsung invested over $15 billion in R&D, and Intel also spent over $10 billion toward developing new products.
Apple will start selling AirPods 3 by the end of 2019
Apple is expected to start selling third-generation AirPods by the end of 2019. One big difference is that the new wireless headphones will have a noise canceling feature. At the level of the companies that will be involved in this project, we have Inventec, from Taiwan, that will be responsible for the production of the AirPods 3, while Luxshare Precision, also from China, will also receive part of the orders.
AirPods 3 arrive until the end of 2019 with new functionalities
Apple has dominated the wireless headphone market and will continue to do so. Statistics show that this company sold 35 million AirPods in 2018, which translates into a 75% global market share. As we said, the AirPod sales boom is expected to continue, with annual shipments for distribution rising to 50 million devices by 2019.
Of course, when a market becomes profitable, competition arises. Inspired by rising sales of AirPods, many brands like Huawei, Xiaomi and even companies like Microsoft, Amazon, and Google are betting on wireless headphones to meet strong demand.
To meet the challenges of rivals, Apple and its partners want to raise the bar.
That said they will add new features to AirPods 3, including the noise canceling function. However, do not think this is an easy task.
Noise canceling technology consumes a significant amount of battery. Since AirPods are not the king in this field, the runtime may be even more affected.
It is not known now what Apple could do and if it is even going to consider a change in design. Because considering the integration of new features, it may be necessary to increase the size of the battery. This requires more space. However, the solution may also involve shrinking the other components to accommodate the larger battery.
However, in addition to the design change, Apple may also be considering adding new colors to AirPods 3.
