The Importance of Using a VPN

A Digital Shield for Your Online Adventures

 

As tech professionals, we often spend a good chunk of our lives navigating the digital realm. Whether you’re troubleshooting a network, coding a new app, or just binge-watching the latest series, one thing is clear: your connection to the internet is a double-edged sword. It’s both incredibly convenient and, if not properly secured, a potential vulnerability.

 

Enter the VPN (Virtual Private Network) our trusty, digital bodyguard. If you’re not already using one, or if you’re not entirely sure why you should, let’s walk through some of the reasons why a VPN is essential for anyone working in IT and, frankly, for anyone who uses the internet.

 

What Is a VPN?

 

In simple terms, a VPN creates a secure, encrypted tunnel between your device and the internet. It allows your data to travel securely, masking your IP address, and ensuring that no one (be it hackers or nosy advertisers) can track or intercept your online activity. Think of it as your personal “cloak of invisibility” in the digital world!

 

1. Enhanced Security

 

One of the biggest perks of using a VPN is the enhanced security it provides. As IT professionals, we know that unsecured networks, such as public Wi-Fi in cafes, airports, or hotels, are prime targets for hackers. Anyone can set up a “free Wi-Fi” network and, once you connect, your data is exposed. With a VPN, your internet connection is encrypted, rendering your data unreadable to anyone trying to intercept it.

 

Picture this: You're working on your laptop in a busy coffee shop, surrounded by the faint hum of chatter and the aroma of espresso. You hop on the free Wi-Fi and start sending sensitive project files. Sounds like a disaster waiting to happen, right? Without a VPN, that hacker sitting across from you could easily intercept your data and walk away with your confidential info. With a VPN, though, you’re safe. It’s like being locked inside a digital vault.

 

2. Privacy Protection

 

Privacy is a fundamental concern for many tech professionals. We all know that browsing the web without a VPN is akin to walking through a mall with a neon sign above your head, proclaiming, “Here’s everything that I’m doing online!” Websites, advertisers, and even your internet service provider (ISP) can track your online movements, building detailed profiles based on your behavior.

 

By using a VPN, your true IP address is masked, making it much harder for anyone to trace your online actions back to you. Whether you're researching the latest security protocols, browsing social media during your lunch break, or trying to access resources for your next big project, a VPN ensures your activities remain private.

 

3. Accessing Geo-Restricted Content

 

As anyone who’s tried to access content in, or from, another country can attest: geo-blocking is real. You may have encountered the frustration of trying to watch a video or use a service, only to be greeted with a message saying, “Sorry, this content is not available in your region.” It’s annoying, especially when you know that the content is just a few clicks away.

 

A VPN solves this problem by allowing you to connect to a server in a different country. This makes it appear as if you’re browsing from that location, granting you access to geo-restricted content. Whether it's accessing an overseas service (e.g., news), gathering research that’s only available in another region, or simply watching your favorite Netflix show (when you're out-of-town), a VPN is your passport to the unrestricted web.

 

4. Bypassing Censorship*

 

In some regions of the world, the internet is heavily censored. Sites and services that we take for granted might be blocked entirely. For IT professionals working in international teams or conducting research, this can be a significant barrier. A VPN can help bypass these restrictions, providing a secure tunnel that lets you access information freely, no matter where you are.

 

While some administrations and organizations try to monitor and restrict access to certain types of content, using a VPN can help you to bypass these limitations. This is particularly useful for professionals who need to access global research, or communicate with colleagues from around the world without restrictions.


*Please note: we are, by no means, advocating illegal activity. If accessing certain sites/information is considered to be illegal in your country - simply don't do it.

 

5. Improved Remote Work Flexibility

 

As remote work becomes more common, a secure connection is more important than ever. Whether you’re working from home, or while traveling, a VPN can ensure that your connection to your company's network is encrypted and secure. This not only helps you stay productive but also ensures that sensitive company data remains protected from potential breaches.

 

Without a VPN, your connection to company servers could be compromised, making it easier for hackers to infiltrate your corporate network. By using a VPN, you can connect securely and access important files and resources without fear of being exposed.

 

6. Avoiding Bandwidth Throttling

 

Have you ever been streaming a video, only to have the quality suddenly drop, or buffering begin just as you’re getting to the good part? In some cases, this may be due to your ISP intentionally slowing down your connection. This is known as “bandwidth throttling”. ISPs may throttle your connection when they detect high data usage when, for example, you are streaming videos or online gaming.

 

A VPN can help mask the data you're transmitting, making it more difficult for your ISP to detect and throttle your connection. This means fewer interruptions and smoother, less interrupted online experiences. 

 

A Small Investment for Big Returns

 

In the ever-evolving digital landscape, security, privacy, and flexibility are paramount. For IT professionals, using a VPN is more than just a best practice; it’s an essential tool to protect yourself and your work. It’s like wearing a seatbelt - something you may not always think about, but definitely something you’re glad you have when it matters most.

 

So, if you're not already using a VPN, what are you waiting for? Your digital self will thank you!

Post-Quantum Cryptography: The Future of Digital Security?

By Rie Vainstein • March 3, 2025
Futureproofing Our Security In our increasingly connected world, the security of digital information has never been more critical. From banking transactions to private communications, our data is constantly transmitted and stored across the internet. The current systems that protect this data rely on cryptography, a branch of mathematics that helps keep information secure by encoding it in ways that are difficult to decode without the proper key. However, with the rise of quantum computers, traditional cryptography is facing new and significant threats. This is where Post-Quantum Cryptography comes into play. What is Post-Quantum Cryptography? Post-Quantum Cryptography (PQC) [1] refers to cryptographic algorithms that are specifically designed to be secure against the power of quantum computers. Quantum computers, once they become practical, will be capable of solving complex mathematical problems much faster than classical computers. This will render many of the encryption methods we rely on today [such as RSA (Rivest, Shamir, and Adleman – initials of the inventors) and ECC (Elliptic Curve Cryptography)] vulnerable to attack. Quantum computers operate on quantum bits, or “qubits”, which can exist in multiple states simultaneously, unlike classical bits that are either a zer (0) or one (1). This allows quantum computers to perform certain calculations exponentially faster than classical computers. For example, in a matter of seconds, a quantum computer could potentially break an RSA key, which is considered secure by today’s standards. As quantum computing technology advances, the need for PQC becomes even more urgent.

Designing a Wi-Fi Network

Designing a Wi-Fi Network This is the first in a series of blogs on Wi-Fi operation, design, and troubleshooting. Designing a Wi-Fi network is much easier if you have the right procedures and tools in place. First you must collect data about the network: What are the requirements of the network? What is the goal of the new network? What is it meant to achieve? Are there any constraints you have to overcome? Next you have to decide what wireless vendor is being used? One of the most important things to get is an accurate map (or plan) of the site and the various floors.
