DNSFilter is a network security company built on protective DNS, serving over 43,000 organizations with threat prevention and content filtering. The tech stack reveals a full-stack product business: React + Next.js frontend, Go + Ruby + .NET backend, with operational infrastructure spanning Salesforce, NetSuite, and HubSpot. Current hiring is heavily weighted toward senior and director roles across engineering and product, suggesting they're scaling capabilities rather than adding headcount — particularly evident in active projects around Windows roaming clients, AI integration into their SDLC, and design system modernization.
