Dnsfilter Expands Capabilities With Strategic Acquisition Of Zorus

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

WASHINGTON, April 7, 2025 /PRNewswire/ -- 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. This strategic move extends DNSFilter's filtering capabilities and reinforces its commitment to Managed Service Providers (MSPs).

The acquisition combines the strengths of both platforms to deliver a comprehensive security solution.

Key Benefits for Customers and MSPs:

• Increased Resiliency and Availability: More resilient and highly available security service through combined infrastructure and expertise, ensuring business continuity.
• Double Down on Partnership with MSPs: Zorus has a strong MSP-first strategy, focusing on ease of deployment and integration with MSP tools. Both companies prioritize understanding and meeting the unique needs of MSPs. Together, this commitment is strengthened to deliver superior service to this community.

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."

Brett Cheloff, CEO, Zorus and former VP of Product, ConnectWise, said: "Joining forces with DNSFilter marks an exciting new chapter for Zorus and our MSP partners.

As the saying goes, 'If you want to go fast, go alone. If you want to go far, go together.' I look forward to working with Ken and the entire DNSFilter team to deliver a comprehensive security experience that empowers our shared MSP community to reach new heights."
