DNS Filtering Help stop web threats before they reach a device
Designed to block malicious websites before a connection is made, DNS filtering uses AI-driven domain intelligence to flag threats days before traditional feeds. No hardware required.
Most web threats are stopped too late
New malicious websites and phishing domains appear faster than static blocklists can track. Standard network security protects users inside the office, but remote and hybrid work has changed where users connect, and traditional edge controls don’t always follow them out the door. The gap between when a threat appears and when it hits a reputation-based feed is where attacks happen. DNS filtering closes that gap by blocking threats before a connection is ever established.
What changes when threats are blocked at the DNS layer
Blocked before devices are reached
Protection that follows users
First client protected in minutes
Security value made visible
Protection built into every DNS query
N-able DNS Filtering powered by DNSFilter™ delivers DNS protection at the query level, so threats are designed to be blocked before data reaches a device.
AI-driven domain classification

Automatic sync of groups and users supports up to 500,000 users, so existing policy structures carry over without manual work.
DNS filtering is a critical part of IT security defense in depth. Being able to protect laptop assets even when they are not on the main corporate network fills a critical hole in security protection.
Ahead of threats before they hit a blocklist
Traditional DNS tools may rely on reputation feeds that update after a threat has already reached victims. AI-driven domain classification identifies malicious and newly registered domains an average of 10 days before they appear on those feeds. That lead time means clients are protected from a threat before it makes the news. DNS-layer filtering can help prevent compromised endpoints from establishing command-and-control callbacks.
I absolutely love [N-able DNS Filtering]. Domain lookup, category blocking, category insights, query log, user security — it is all spot on and great for a business of any size.
