Using SafeDNS

DNS-layer filtering

DNS filtering is the most comprehensive web filtering technique. It blocks unwanted sites altogether before users access them. DNS filtering blocks both HTTP and HTTPS sites. DNS filtering is indispensable for blocking malicious sites, as over 90% of malware uses DNS to carry out malicious campaigns.

Category-based filtering

SafeDNS users decide which categories of content to block or allow on their network. We provide 61 categories to choose from.

High precision filtering

To deliver users an exceptionally accurate web filtering, the company uses its own web categorization database with 109M sites, distributed in several dozen content categories. With the database information we analyze each DNS query from SafeDNS-protected devices to define what content categories the requested site belongs to. The queries for sites from user allowed categories are successfully resolved into IP addresses of the requested sites. Otherwise, SafeDNS shows users a service block page – instead of the requested site from user blocked categories.

Families with kids

Offer your home users an easy-to-use parental control service for protecting children against anything the family people hate about the internet – pornographic and adult-only content, social media and gaming sites, in a word, any unwanted content.

Business & nonprofits

Provide your corporate users with an additional safety layer in the corporate multi-layered cyber security strategy. Allow employers to limit online activity of their staff to work-related sites only.

Education & libraries

Give educators a useful tool for regulation compliance and appropriate internet policy enforcement at libraries and educational institutions of any level from kindergartens to schools to colleges and universities.

Public WiFi owners

Help WiFi hotspot owners welcome guests of any age by providing them with a family-friendly internet, free from dangerous, gross and explicit sites.

Regulation compliance

Internet policy compliance

Increased productivity

Family-friendly internet

With the SafeDNS-based web filtering, families with children will have no worries as to what websites their young web surfers visit. Restrict kids’ access to any unwanted web content to provide the parents with a peace of mind.

Malware & phishing-free internet

Make the filtering for your entire subscriber base an additional cyber security layer against botnets, malicious and phishing sites. Let no malware penetrate and lurk on your network, infecting ever more user devices.

Choice on who manages the filtering

You are to decide whether to manage the filtering on your side or allow the subscribers do it.

Protection against child abuse content

Block the 2 dedicated filtering categories to make sure your users access no sites with child sexual abuse images and videos. Both these categories contain the similar illegal content from the IWF Child Abuse Image Content List, which SafeDNS receives as IWF Member, and a list compiled by the Canadian Centre for Child Protection, as part of its Project Arachnid.

Anti-extremism protection

Filter out terrorism-promoting content which poses threat to young and adult minds alike. To protect users against terror-related content, SafeDNS adds a list of sites, compiled by Counter Terrorism Internet Referral Unit run by the Metropolitan Police, UK to a filtering category, named 'Hate & Discrimination'.

Ad blocking

To get rid of distraction and further improve your subscribers’ online safety, filter out web advertisements. Firstly, they are a nuisance and the internet ads pose additional threat as bad actors use the ads for malware propagation. The ad blocking is in demand with web browsers.

Safe mode for Google, Bing & YouTube

Enable SafeSearch Mode for Google and Bing and Restricted Mode for YouTube out of your personal Service Dashboard. In these modes gross and explicit content is blocked from the search results and videos, marked as inappropriate for kids by YouTubers, are filtered out.
