Frequently Asked Questions
DNS filtering blocks access to malicious or unwanted websites by checking every DNS request against security and content policies before the connection is made.
Because it works at the DNS layer, it protects every device on or off your network, with no extra hardware or browser plugins.
No. Web filtering inspects pages after a connection is made, often through a proxy or browser plugin. DNS filtering blocks the connection itself, before any content loads. It is faster, works on every device, and stops threats that never reach the browser.
Protective DNS (PDNS) is a security service that blocks DNS requests to known malicious domains. The NSA and CISA recommend it as a baseline defense. DNSFilter adds AI-based threat detection and content controls on top of that baseline.
Most organizations deploy DNSFilter in under an hour. Point your network's DNS to DNSFilter, or install the Roaming Client on devices that leave the office. No hardware to rack, no appliances to maintain.
Yes. Block individual domains, entire content categories, or whole applications with one click using AppAware. Universal block and allow lists apply your rules everywhere at once.
