By effectively mitigating risks, organizations can significantly boost both safety and productivity while engaging with the web. In the current digital environment, businesses necessitate comprehensive strategies to protect their internet traffic, ensuring it remains secure, private, and transparent. The traditional domain name system (DNS) is primarily designed to resolve internet queries through a global network of servers, converting those inquiries into specific Internet Protocol (IP) addresses. However, this vital service was not initially developed with security as a key consideration, resulting in various exploits and vulnerabilities within the DNS architecture. Organizations can utilize protective DNS solutions, such as Webroot® DNS Protection, to enhance their control over networks while guaranteeing the essential security, privacy, and visibility for their IT infrastructure and users, including those working remotely. The primary aim of this solution is to create a strong, private, and manageable connection to the internet. Moreover, automated filtering driven by Webroot BrightCloud® Internet Threat Intelligence effectively blocks malicious requests, further boosting the protection of online activities.

DNSEye is a tool that identifies harmful network traffic and assesses whether this traffic can be mitigated by your existing security systems. Since DNS is integral to all protocols such as HTTP, HTTPS, and IoT, it provides comprehensive insights into your entire network, no matter the protocol in use. However, data loss prevention (DLP) solutions often fall short in recognizing data exfiltration attempts that utilize DNS tunneling techniques. To effectively address this issue, a thorough analysis of DNS logs is essential. Alarmingly, approximately 80% of domains associated with malware do not possess an IP address, which makes DNS logs the only avenue for identifying malware requests lacking an IP. The logs generated by DNS servers can be extensive and complex, making interpretation challenging. DNSEye simplifies this by enabling the collection, enhancement, and AI-driven classification of DNS logs. Its sophisticated integration with Security Information and Event Management (SIEM) systems optimizes efficiency for Security Operations Center (SOC) teams by transmitting only the pertinent data they require. Furthermore, DNSEye is capable of aggregating logs from a wide range of DNS servers, encompassing various brands and models, without necessitating any modifications to your existing network infrastructure. This seamless integration enhances your overall network security posture while minimizing disruption.

A DNS (Domain Name System) changer transforms web addresses like Surfshark.com into the numerical IP addresses necessary for devices to communicate effectively. Your default DNS provider is often your Internet Service Provider (ISP), which can track your online behavior and store your browsing records. By opting for a DNS changer, you can significantly boost your privacy since it encrypts your DNS queries and enables connections to public DNS servers from external providers. Adjusting your DNS settings is quite easy; you can do this manually through your device’s Wi-Fi settings by modifying the network configuration. For added convenience, the Trust DNS app offers a user-friendly solution, allowing you to change DNS servers with a single tap. There are two main ways to use the Trust DNS app: you can either enable its server for enhanced browsing privacy or connect to one of several free third-party DNS servers that provide additional features like content filtering, ad blocking, and malware protection. This variety of options ensures that users can select the solution that best fits their preferences while improving their overall online experience. Ultimately, utilizing a DNS changer not only safeguards your privacy but also enhances your internet browsing efficiency.

Implementing preventive strategies is significantly more advantageous than addressing problems after they surface, especially in the field of cybersecurity.
