Family Filter

Blocks access to adult content, proxy and VPNs, phishing and malicious domains. It enforces Safe Search on Google, Bing, Brave, DuckDuckGo and YouTube. The filter does not log your requests, IP addresses and other activities. Blocked domains are send to NXDOMAIN, which does not track. [11]

Adult Filter

Less restrictive than the Family filter and only blocks access to adult content and malicious/phishing domains.

Security Filter

Blocks access to malicious and phishing domains [12] . It often performs very well on detection tests between providers [13] [14]
