Cloudflare

Cloudflare is a global network providing CDN, DDoS protection, DNS, and a growing edge-computing platform (Workers, Pages, R2). It sits in front of a large share of the web to speed up and secure sites.

DNSFilter

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.

NextDNS

NextDNS is a customizable DNS-based content filtering and privacy protection service. It allows users to block unwanted content, protect their online identity, and customize their internet experience.

Cisco Umbrella

By leveraging DNS, secure web gateway, and cloud‑delivered firewall capabilities, it blocks malicious domains, IPs, and files before they can compromise devices. The service integrates with existing network infrastructure and offers real‑time visibility, policy enforcement, and detailed reporting, helping organizations reduce risk and simplify security operations across distributed workforces.
