The world is becoming more and more interconnected for every day that passes. This interconnectedness has many upsides, including easy access to communication platforms, news, and information. However, the high level of interconnectedness also has a downside, mainly the increasing need for cybersecurity against vicious cyberattacks.

Since digital technologies continue to develop, the landscape of cyber threats is ever evolving, which means that safeguarding sensitive information and maintaining privacy is crucial.

Virtual Private Networks, also known as VPN, attempts to address the risks of cyberattacks and their ever-evolving nature. VPNs offer a layer of protection, which helps users to navigate the internet with greater security and anonymity.

Introducing VPNs - know the basics

To understand the basic setup of a VPN, you should picture a tunnel: A tunnel protects the traffic that is within the tunnel from outside interference. Similarly, a VPN creates a tunnel which is secure and encrypted. This means that the connection between the user's device and the internet is secure. To ensure the tunnel, the internet traffic is routed through a remote server, which is being operated by the VPN provider.

This tunnel ensures that the user's IP address is masked and that their online activities are encrypted. The main functions of a VPN are the following:

Encryption. VPNs encrypt data transmitted between the user's device and the VPN server.

IP masking. Since the traffic is routed through a VPN server, the IP address is hidden, and a new IP address from the VPN server is assigned.

Secure access to networks. Using a VPN ensures secure access to remote networks, enabling people to connect securely to the organization’s internal systems.

Bypassing geo-restrictions. Some websites use geo-restricting codes, meaning that based on your location, you have limited access to content. A VPN can bypass this, which addresses the challenge of unequal internet access.

A way to enhance privacy & security

The baseline for VPNs is to enhance privacy and security. This is to address the growing concerns about data privacy and surveillance, which is becoming an increasing matter in the rise of digital services. One thing that VPNs can protect against are Internet Service Providers (ISPs) and other third parties from tracking your online activities. This is often done to target advertising and collect data, but the VPN prevents these entities from monitoring your browsing history.

VPNs can also ensure secure communication, by protecting the channels from malware. This also includes phishing attacks, which is when one creates fake accounts in attempt to place malware. VPNs are also useful when using public Wi-Fi networks, as these often are insecure and thereby susceptible to cyberattacks. By providing a secure connection, VPNs can protect against online threats. Lastly, VPNs can mitigate government surveillance. Some regions have very strict internet censorship and surveillance, but VPN is becoming an important tool to bypass these government restrictions and maintain online freedom and privacy.

The limitations of VPNs

Although VPNs offer a lot of good tools for protecting privacy and security, there are also some limitations to VPNs, which are important to understand to most effectively protect yourself. Firstly, VPNs do not offer a complete security solution. They do enhance privacy and security, but they do not protect from all types of cyber threats. This is why VPNs are recommended alongside other security measures, which includes antivirus software, firewalls, and a strong password.

There are many VPN providers, but not all are equally good. Some VPN providers log user data or might have inadequate security practices. It is therefore important to research and compare VPN providers and choose one you trust. Furthermore, VPNs rely on specific protocols for encryption and security. Some older or less secure protocols might be vulnerable to attacks, so when picking a VPN provider, you should ensure the one you pick uses up-to-date and secure protocols. Lastly, in some jurisdictions, the use of VPNs might be restricted by legal and compliance issues. Be aware of your opportunities within your region.

The role of VPNs in business & remote work

For many businesses, work has become equivalent to remote work. To enable remote setup, VPNs have become crucial in securing the access of employees. With a VPN, employees can securely access corporate networks, which ensures that sensitive business data remains protected. Furthermore, VPNs also safeguard intellectual property and information from potential threats, both from competitors and from malicious actors.

There are data protection regulations in most industries, which emphasize data protection. Both GDPR and HIPAA are important data protection regulations to comply with. A VPN helps a business to comply with these, since it ensures that the data transmitted is encrypted and secure. Lastly, a VPN can facilitate secure communication channels between remote employees and corporate systems, which reduces the risk of data breaches and unauthorized access.

Concluding remarks

There is no doubt that VPNs play a crucial role for individuals and business in the digital era we are in. With the many upsides to VPNs, and knowledge about the limitations, individuals and business can navigate the world of cybersecurity and implement the use of VPNs effectively.
