Insight Partners, a global venture capital and private equity firm, led a $30m Series A round in DNSFilter, a DNS threat protection provider. "The traditional model of top-down, hardware-centric network security is disappearing in favor of solutions that readily plug in at the device level and can cater to highly distributed workforces. DNSFilter's rapid growth and efficient customer acquisition are a testament to the benefits and ease of use compared to incumbents," Thomas Krane, Insight Partners Principal.
