US-based web traffic management software developer NS1 has received $33m in a series C round led by Dell Technologies Capital, the corporate venturing vehicle for computing technology producer Dell.
Networking security firm Cisco, enterprise software publisher Salesforce and telecommunications firms Deutsche Telekom and Telstra also took part, through subsidiaries Cisco Investments, Salesforce Ventures, Deutsche Telekom Capital Partners (DTCP) and Telstra Ventures.
The deal was rounded off by Entrée Capital, Flybridge Capital Partners, GGV Capital, Two Sigma Ventures, Sigma Prime Ventures and Mango Capital. Tyler Jewell, managing director at Dell Technologies Capital, will join the board of directors at NS1.
Founded in 2013, NS1 has created a software product called Anycast that prevents congestion on enterprise web services and apps by assigning data traffic through the domain name server (DNS) closest to the user’s IP address.
The company also provides software that integrates the management of user IP addresses and DNS names, and a group of tools which help precipitate malevolent DNS attacks. The funding will help it meet customer demand and garner additional business for edge computing, service delivery and internet-of-things apps.
The company said it has now raised $85m altogether. GGV Capital led a $20m round in mid-2017 that included DTCP, Salesforce Ventures, Telstra Ventures, Flybridge Capital, Sigma Prime Ventures and Two Sigma Ventures.
The latter three had already taken part in a series B round for NS1 in 2016 that was sized at more than $20m and led by DTCP, before Telstra Ventures added an extension of undisclosed size shortly afterwards.
Flybridge and Sigma Prime co-led NS1’s $5.4m series A round, which also featured Founder Collective, Center Electric and assorted angel investors, in 2015.
