DNSFilter Expands Capabilities with Strategic Acquisition of Zorus

Delivering Improved End User Protection, Increased Resiliency, and a Deeper Commitment to MSP Partners

WASHINGTON, DC – April 7, 2025 – DNSFilter, a cybersecurity leader in content and threat filtering at the DNS layer, today announced its acquisition of Zorus, an innovative provider of endpoint-based web filtering and user behavior analytics.

Ken Carnesi, CEO, DNSFilter, said: “This move brings together the best of both worlds: DNSFilter’s unmatched AI-driven threat intelligence and Zorus’ deep understanding of the MSP space. DNSFilter was born in the MSP world, and this acquisition reaffirms that commitment. Brett and his team bring serious talent and focus—they live and breathe MSP. They’re not just joining us; they’re helping lead the charge. Together, we’re building something that raises the bar for what MSPs should expect—and this is just the beginning.”
