Implementing protective filtering is essential for ensuring security, visibility, privacy, and control over internet interactions. By effectively reducing risks, organizations can enhance both safety and productivity while navigating the web. In today's digital landscape, businesses require comprehensive management to safeguard their internet traffic, ensuring it remains secure, private, and transparent. The existing domain name system (DNS) primarily serves to resolve internet requests via a worldwide network of servers, translating those requests into distinct Internet Protocol (IP) addresses. However, this crucial service was not originally built with security as a priority, leading to numerous exploits and vulnerabilities within the DNS framework. Organizations can leverage protective DNS services, such as Webroot® DNS Protection, to gain greater control over their networks while ensuring the necessary security, privacy, and visibility for their IT infrastructure and users, including those operating remotely. This solution's main objective is to establish a robust, private, and manageable connection to the internet. Additionally, automated filtering powered by Webroot BrightCloud® Internet Threat Intelligence effectively blocks harmful requests, further enhancing the protection of online activities. As a result, businesses can confidently navigate the complexities of the internet with a fortified defense against potential threats.

DNSservers generate a large number of difficult-to-understand logs. DNSEye allows for the collection, enrichment and AI-based classifying of DNS logs. Its advanced SIEM integration saves time and EPS because it transfers only the data needed by SOC teams to SIEM. DNSEye collects logs from a variety of DNS servers, including many different brands and models. This can be done without requiring any changes to your network structure.

A DNS (Domain Name System) changer converts web addresses such as Surfshark.com into the numerical IP addresses essential for machine communication. Typically, your DNS provider is your Internet Service Provider (ISP), which has the capability to monitor your web activity and retain your browsing history. By using a DNS changer, you can enhance your privacy since it encrypts your DNS requests and allows you to connect to public DNS servers provided by third parties. Changing your DNS settings is relatively straightforward; you can manually adjust them through your device’s Wi-Fi settings by editing the network configuration. Alternatively, you can simplify the process by using the Trust DNS app, which enables you to switch DNS servers with just one tap. There are two primary methods to utilize the Trust DNS app: you can either activate its server for improved browsing security or connect to one of the free third-party DNS servers that offer features like content filtering, ad blocking, and protection against malware. This flexibility ensures that users can choose an option that best suits their needs while enhancing their online experience.
