Private DNS is a technology that assigns text-based names to networked resources, allowing users and systems to rely on IP addresses instead of traditional domain names. This enables easier management of network administration and improves user experience by caching frequently visited websites. Private DNS servers are managed within an organization's internal network perimeter, providing more control over network usage and security. However, public DNS has security flaws that make it vulnerable to cyberattacks, with 87% of organizations experiencing more than seven DNS attacks per year. Twingate's Zero Trust solution uses software-defined perimeters and transparent proxies to protect private DNS infrastructure from hackers, reducing the attack surface and improving overall network security.
