About this category

DNS security tools protect your clients when their devices try to connect to a domain. These products intercept DNS requests, blocking known malicious sites, phishing attempts, and unwanted content categories. The category contains 28 products from various vendors.

Look for solutions that offer granular control over content categories. ScoutDNS, for instance, provides over 67 content categories, along with YouTube and Safe Search controls. ThreatSTOP's DNS Defense Cloud uses AI to identify and block emerging malicious domains, adapting to new threats faster.

Most products here don't list direct PSA integrations, so plan on managing these solutions separately from ConnectWise PSA or Halo PSA. N-able's Filtering offers an API for custom integration work. Heimdal Security's Security Network also uses AI for threat detection.
