In our increasingly digital world, the Domain Name System (DNS) plays a vital role in connecting our devices to websites. However, traditional DNS services provided by internet service providers (ISPs) may lack adequate security and protection against various online threats. In this article, we will introduce ProtonDNS, a user-friendly softwareless solution that offers enhanced security and protection for your online activities.

What are DNS servers and how do they translate IPs to human-readable domains?

When we enter a website's name (e.g., www.alvosec.com) into our web browser, our device needs to know the corresponding IP address (e.g., 192.168.0.1) to establish a connection. DNS servers act as the internet's phone book, translating human-readable domain names into IP addresses. They enable our devices to find and access websites by handling this translation process.

Every device already uses DNS from the internet provider

By default, when we connect to the internet, our devices automatically use the DNS servers provided by our internet service provider (ISP). These servers facilitate the translation process mentioned earlier. However, relying solely on ISP DNS servers can have limitations in terms of security and protection.

The lack of security and protection provided by ISP DNS servers

Unfortunately, ISP DNS servers often prioritize speed and efficiency over security measures. As a result, they may not provide adequate protection against phishing, scams, malware-infected websites, and other online threats. This leaves users vulnerable to various risks while browsing the internet.

ProtonDNS: A softwareless solution for enhanced security and ease of use

ProtonDNS offers a compelling alternative to traditional DNS services. It is a softwareless solution, meaning you don't need to install any additional software on your device. This makes it incredibly easy to use across different platforms, such as computers, smartphones, and tablets.

Protection against malicious websites, phishing, and scams - especially for Web3

ProtonDNS goes beyond basic DNS services by providing enhanced protection against malicious websites, phishing attempts, and scams. It uses advanced security measures to detect and block access to these harmful online destinations. This is particularly important as we transition into the Web3 era, where decentralized applications and cryptocurrencies require heightened security.

Blocking ads, NRD domains, ransomware, and adult content

In addition to protecting against malicious websites, ProtonDNS offers several other advantages. It can block intrusive ads, preventing unwanted distractions and potentially malicious content. It also helps to safeguard against NRD domains (newly registered domains), which are often used by cybercriminals to launch attacks. Furthermore, ProtonDNS helps in blocking ransomware threats and restricting access to adult content, ensuring a safer browsing experience.

Why DNS protection is important and its advantages over software solutions

DNS protection is crucial because it acts as the first line of defense against online threats. By using ProtonDNS, you benefit from enhanced security without the need for additional software installations. Unlike software-based solutions, ProtonDNS works at the network level, providing protection to all devices connected to the network. This means you are protected across different devices without having to individually set up and maintain separate security software.
