Leverage Leading DNS Infrastructure from a Name You Can Trust to Improve Availability and Performance

Improve the availability of your organisation's website(s) and other Internet assets by leveraging Verisign’s global, securely managed DNS infrastructure. Our service is built on our patented, proprietary technology, Advanced Transaction Look-up and Signalling (ATLAS®), that performs at 100 times the processing capacity of its DNS predecessor, maintaining the speed and reliability of connections, as well as integrating new protocols quickly and efficiently.

Verisign Managed DNS service helps you avoid capital expenditures, while decreasing the costs associated with premise-based DNS management; lowering your company’s total cost of ownership.

Maximise Availability

Improve Security

Protect your online revenue, reputation and brand with Verisign’s redundant DNS infrastructure that mitigates the risk of network/server outages caused by distributed denial-of-service (DDoS) attacks. Verisign Managed DNS service utilises our patented, proprietary technology, ATLAS. Since ATLAS does not rely on BIND software, it is much less vulnerable to security flaws than other DNS platforms.
