Secure64 LineGuard offers the fastest protective DNS (pDNS) cloud solution available globally, with an industry-leading average query response time of just 12 milliseconds, significantly outperforming Cisco Umbrella’s 20+ milliseconds. In addition to its superior speed, LineGuard delivers a much lower total cost of ownership (TCO), making it a more cost-effective choice for organizations of all sizes. Unlike legacy platforms with limited innovation, Secure64 continues to actively develop new features and advanced capabilities, offering far more functionality than Cisco Umbrella. LineGuard includes powerful tools like EDNS support and source IP filtering for precise policy enforcement, along with a dedicated team of Customer Success Managers who ensure seamless migration and help organizations optimize their threat-blocking strategies from day one.
