In their own words
Control D
Control D is a configurable DNS filtering and traffic redirection service for controlling access to domains, services and browsing activity. Its filtering includes 20 content categories, custom rules and more than 1,000 premade services that users can block or allow. Malware protection uses threat intelligence feeds and machine learning, with selectable aggressiveness levels. DNS connections support DNS-over-HTTPS, DNS-over-TLS, DNS-over-QUIC and DNS-over-HTTPS/3, as well as IPv4 and IPv6. Listed integrations cover Windows, macOS, Linux, iOS, Android, browsers, routers, RMM tools and Tailscale. API access includes generating and invalidating tokens. Raw query logs are retained for 30 days and lower-resolution analytics for up to one year; customers can choose analytics storage in New York, Amsterdam or Sydney. A free plan is available. The SMB plan costs $2 a month, billed per endpoint, and includes self-serve deployment and real-time analytics. Control D was founded in Toronto in 2021.
