As part of the funding, GGV Capital's Glenn Solomon will join NS1's board.

The technology landscape for online businesses has become increasingly complex as cloud, DevOps and other major technology trends have taken hold. At the same time, network outages and malicious attacks have become more prevalent; all while internet audiences have come to demand perfect availability and snappy performance. NS1's software and services help companies navigate these challenges by implementing intelligent DNS and traffic management to optimize application delivery and keep their websites up and running. The company will use this financing to help even more online brands take control over their traffic and infrastructure to build reliable, high performance applications.

A leader in DNS and traffic management space: Since its inception in 2013, NS1 has quickly established itself as the technology leader in the DNS ecosystem, with major customer wins among the highest trafficked internet brands, including Dropbox, Imgur, Pandora, Yelp and many more.

Rapid expansion into enterprise segment: Since its Series B financing in 2016, the company has landed key enterprise customer wins including The Guardian and Weight Watchers. Enterprise demand for NS1's software and services has accelerated as a result of critical enterprise technology initiatives for digital transformation, operational efficiency, DDoS resiliency and datacenter automation.

Accelerated investment in software and services: NS1's platform technologies, with data driven real-time global traffic management and deep API automation capabilities, will continue to expand as the company increases investment in its world-class engineering team and global network infrastructure. Recent product launches include NS1's self-service Developer Edition plans and Managed DNS for China, which enables enterprises to more effectively address the Chinese audience.

Kanwar Gill, senior director of DevOps at Weight Watchers, said: "At Weight Watchers, we trust NS1 to deliver mission critical DNS and traffic management for our key domains. Like most tech companies, we're focused on rock solid, high performance, operationally efficient application delivery, and to provide the best service to our users, we have built a delivery stack that's modern, automated and resilient. NS1 is a critical part of that stack: they are pushing the boundaries of DNS technology, and we've been blown away by the quality of service we've received from the NS1 platform and team. As a customer, we're thrilled for this new funding round and excited to see NS1 continue to invest in their software and platform."

Kris Beevers, NS1's cofounder and CEO, said: "With the shifting DDoS threat environment and copious M&A activity, the DNS and traffic management market has seen rapid change since we raised our Series B round late last year. Today, NS1 is the only major provider focused solely on the delivery of mission critical DNS and traffic management software and services to internet and enterprise companies. We are just getting started: DNS has long been an underappreciated opportunity to take granular control over internet traffic, and it's the entry point to every online application. By unlocking the potential of DNS with our unique software and delivery platforms, NS1 will continue to solidify its position as the clear market leader in DNS. We're excited to continue our mission to build a smarter internet and become a foundational internet player in the coming years."

Glenn Solomon, managing partner, GGV Capital, said: "NS1 has completely re-thought how DNS and traffic management should be performed and has brought to market a software-driven, modern solution. Having spoken to many leading internet scale and enterprise customers and prospects, it's clear the market is blown away by the capabilities, performance and service levels of the NS1 solution. At GGV Capital we seek to invest in global leaders, and we're highly confident NS1 is on the path to becoming a must-have for all the top internet and enterprise players."
