Powerful Categorization

Catblocker is Netsanity’s premium content filtering engine. Using public and private databases, Netsanity’s own artificial intelligence engine, and other proprietary tools, we maintain a database with many millions of websites and apps. Catblocker will work regardless of the browser or app being used. Use Apple’s Safari browser or feel free to use Google’s Chrome, or Firefox and many others – let your child or teen decide and know that they are protected regardless.

Block what you want

Our catblocker has neat options too. For instance, you can block or allow uncategorized sites. There are thousands of new sites added hourly. Some are innocent and some dangerous and inappropriate. By blocking uncategorized sites, catblocker will block all sites that are not cataloged and not in our database. This ensures that only sites and categories you approve are allowed. Another option for parents is to allow background traffic. Innocent traffic from, for instance, can be passed even if a certain category blocks it.

Frequently Asked Questions

How many categories are filtered using Netsanity Lite?

Netsanity blocks one category (Adult Pornography) only. All other categories can be unblocked by simply
upgrading to one of our premium plans, which have 30+ categories.

How can I prevent new sites from showing up if they are not yet categorized?

We have an option to block all uncategorized sites. This is useful for younger children who need maximum
proitection. With that turned on, only sites which have been previously cataloged are allowed

Can I allow a site even though its blocked in a category?

Sure. If you want to allow a specific site that is in a category that you are blocking, simply allow it
in siteblocker. That will take precedence.

Very quick to respond and was very helpful!


Great, fast service!


We were very happy that there was no issue with using data with the VPN used by net sanity. Though the safe search issue was frustrating, we were totally happy with the service provided by the support/tech team in solving it as quickly as possible! I'm already certain I'd recommend net sanity to others. Thanks!


Been using your parental controls for two weeks and love the service. It is truly unique in its capabilities for iOS devices.


Thanks to the tech and support team for promptly communicating with us for several hours to solve the safe search issue - and resolving it!


Customer service is top notch!

Keep it up and thanks for all you do! We now can use these iOS parental controls at my sons school with the new safe wifi feature. They were blocking it before so it works great again! Anyway let us know when the Android version is out.

Just a shout out and thank you for the discount! Our small school has about 8 tablets for special needs children. We use Netsanity exclusively to help monitor and control the content on the kid's iPads. They do not need to do anything and we control everything remotely.


I asked for Meet Me to be added to Appblocker. A few days later, I got an email from Netsanity that they were going to add it and they did! That is cool! Thanks again.
