Authoritative DNS

Companies face challenges managing authoritative DNS due to increasing traffic loads, complex hybrid environments, and rising cyber threats like DDoS and DNS hijacking. Maintaining global availability, low latency, and accurate zone replication across regions is difficult. Misconfigurations, outdated infrastructure, and lack of redundancy often lead to outages or security vulnerabilities, impacting reliability and trust.
