DNS Filtering

Netsweeper makes security simple by providing a highly scalable embedded DNS service. The Netsweeper Powered DNS Filtered Technology is a scalable, reliable, and managed authoritative DNS service. The service provides low latency, high availability and is a cost-effective way to make Netsweeper policy enforcement and services available to your users. Capabilities include but are limited to: the ability to deny with a hostname; the ability to deny with an IP; per URL deny rewriting and allows for safe search enforcement in lists.

 

DNS Deployment

Specify Netsweeper as DNS Server for filtered users
Filtering is at the hostname level when the DNS lookup is made
Per user filtering policy is enforced based on unique IP – requires RADIUS or DHCP logs integration
Enforce Safe Search on Google and Restricted Mode on YouTube
Traffic is logged at the hostname level and reports can be generated
Ideal for managed networks e.g. schools & enterprise where users are restricted from changing network settings
