Constellix vs DNSFilter
Side-by-side comparison of features, pricing, ratings, and alternatives.
Constellix is a managed DNS platform, now operating as a DigiCert company, built around enterprise-grade multi-CDN management, traffic routing and DNS availability. It aims to prevent outages and optimize content delivery performance by intelligently routing traffic and monitoring uptime across a business's infrastructure. The platform includes companion tools such as Sonar for uptime monitoring and an analytics dashboard for visibility into DNS and routing performance, and is positioned for enterprise customers that need high-availability DNS alongside multi-CDN failover. Since joining DigiCert, Constellix retains its own brand while being integrated into DigiCert's broader DNS and security product lineup.
DNSFilter blocks malicious domains, phishing sites, ransomware, and unwanted content at the DNS layer before a device can connect, using an AI model the company says catches newly registered and weaponized domains up to 10 days ahead of third-party threat feeds. It serves enterprises, MSPs and MSSPs (with a multi-tenant dashboard used by over 6,000 partners), schools, healthcare, finance, hospitality, and government customers. Beyond blocking, features like AppAware allow one-click blocking of risky applications, CyberSight adds user behavior analytics to spot shadow IT, and a global anycast network keeps DNS resolution fast. It deploys without on-site hardware, includes DNSSEC validation, and is priced per license with volume-based rates that drop as license count grows.
