It is probably an uphill battle for you as a telecom operator or ISP to get higher revenues while proving your company is socially responsible. Let alone, distributed denial-of-service (DDoS) or similar attacks, and undesirable content all over the web which make your network flounder.

Perhaps too, you’re wondering whether you will be able to deploy a solution which can bring you both profit and network reliability for your corporate and residential users in a timely manner against such cyber threats.

SafeDNS provides you with cloud-based security solutions that handle your network vulnerabilities and help your business with smooth sailing during their implementation.

Give your revenue and subscribers’ cyber security a boost

Using SafeDNS

DNS-layer filtering

DNS-based filtering is the most comprehensive web filtering technique. It blocks unwanted sites altogether before users access them. It also restricts accesses to both HTTP and HTTPS sites.
Other than that, 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 6 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 domain queries 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.

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

Any kinds of for-profit and nonprofit organizations.

Education & libraries

Libraries and educational institutions of any level – from kindergartens to universities.

Public Wi-Fi owners

Guest and public wireless networks at public venues.

Regulatory compliance

Block any illegal content so that your clients comply with corporate internet policies and the regulation, concerning filtering out pornography and child abuse content. SafeDNS is Children’s Internet Protection Act compliant, which is vital for K-12 schools and libraries subject to CIPA in the U.S. Germany’s educators and Wi-Fi hotspot owners can block illegal sites from a list, maintained by Federal Department for media harmful to young persons (BpjM).

Internet policy compliance

Make it possible for employers to enforce the internet use policy for their staff members. Blocking access to irrelevant and pornographic content will drive productivity and help employers to avoid law suits about a hostile work environment.

Increased productivity

Employers will appreciate an efficient tool to increase workforce productivity. Upon deploying SafeDNS, employers will be able to limit online activity of the staff to relevant, work-related sites only.

Family-friendly internet

Parents with kids who connect to your internet will not have to worry about unwanted or explicit sites with the SafeDNS web filtering service on.

Malware & phishing-free internet

Use SafeDNS to prevent your employees and visitors from accessing sites with cryptomining malware or phishing which can harm your entire network, user devices, and steal valuable info. To protect your users against these cyber threats, filter out all security-related categories of content in the SafeDNS service management panel.

Revenue & loyalty driver

Increase the average revenue per user (ARPU) and customer lifetime value (CLTV) by charging an additional fee for any filtering-based services


No limit on the number of customers and scaling of the filtering. You will be able to add new users to the filtering list by purchasing more SafeDNS licences.

White labeling

Promote your own company – brand the filtering with your corporate logo and custom domain, and introduce a new value-adding service to your customers stamped with your brand only.

Choice on who manages the filtering

You are to decide whether to manage the filtering on your side or allow the subscribers do it. You can create a child-friendly service plan with the same filtering settings for all subscribers who buy this plan. Or you can give your corporate and residential users an opportunity to decide what content to block or allow on their networks so the filtering meets user demands 100%.

Custom domain for your filtering users

The customized domain name might be, let’s say, ‘’. The domain and service dashboard on it will contain your logo. Thus, your clients will see the customized brand login page and dashboard with the relevant set of features.

  • Custom branded login page

  • Custom branded filtering settings page

  • Custom branded block page

Protection against child abuse content

Because we signed a partnership agreement with the Internet Watch Foundation (IWF) and the Project ARACHNID, both advocates of the fight against child sexual abuse, our database gets permanently updated about the resources and domains considered inappropriate for children. Hence, you can ensure your Wi-Fi users do not visit websites with child sexual abuse images or videos. You may block the two dedicated filtering categories SafeDNS provides for child sexual abuse content-related sites.

Anti-extremism protection

Filter out terrorism-promoting content which poses a threat to young and grown-up individuals. 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 of the UK, to a filtering category named 'Hate & Discrimination'.

Ad blocker

To get rid of annoying distractions and further improve your Wi-Fi safety, filter out web ads, as a majority of them very often help vehiculate malware.

Safe mode for Google, Bing & YouTube

Enable ‘SafeSearch Mode’ for Google and Bing, and ‘Restricted Mode’ for YouTube from your personal Service Dashboard. With the two modes, gross and explicit content is blocked from the search results and videos deemed inappropriate for kids on YouTube.
