Why NxFilter

Faster and lighter

Filtering requires an extra process for your network. It can be a bottle neck in your network and causes a latency problem. NxFilter uses lightweight DNS protocol for its filtering. With NxFilter, there’s no latency problem.

Boost up your network performance

NxFilter doesn’t just do the filtering. It caches DNS responses from public DNS servers. Once it cached, it will be resolved in your local network. It will save a lot of bandwidth and improve your network performance.

Scalability

We see many sites running NxFiler with several thousand users. At the moment, the biggest number of users for a single NxFilter server we have seen is 40,000. We don’t know its limit yet.

Authentication

You want to protect your network with a login procedure and differentiate users with userames and IP addresses on a report view. NxFilter offers IP and password based authentication by itself.

Active Directory integration

You can import users and groups from an Active Directory domain and you can filter them by multiple policies based on those imported groups and users.

Single sign-on

Your users don’t want to go through any other login process after they logged-in to their PCs. NxFilter provides several kinds of single sign-on agents. Some of them can be used for Active Directory integration.

Multiple policies

You can have multiple policies for your users. One policy for staffs and a stricter policy for your students. You can apply these policies based on IP and IP ranges or users and groups created on NxFilter GUI or imported from your Active Directory domain.

Easy deployment

You can say that NxFilter is the easiest webfilter to install and manage. Many of our users are not high skilled professional network engineers. We put everything into a small package and you just install it and run it.

Remote filtering

We provide remote filtering agents for Windows and Chromebook. You can filter your users while they are away from your office or school. We offer these agents for free.

Community proven

You don’t believe everything they say. There are so many best webfilters out there. But only several of them have working communities. We have been running a public user forum since we released the first version of NxFilter in 2013.

Very stable

Many of our users never reboot their NxFilter systems for several months. It doesn’t ask you continuous care. Leave it running and you can spend your precious time on other things to do.

Malware and botnet detection

Malwares and botnets are basically network client programs. They are heavily relying on DNS protocol. NxFilter is capable of detecting and blocking them based on DNS packet inspection.
