Three parental control solutions certified
AV-Comparatives provides certification for parental control software. Parental control solutions are tested against 2,000 URLs with undesirable content in different categories, and 100 child-safe URLs. In order to be certified, a product must block at least 98% of pornographic websites, have no more than a few false alarms on child-friendly websites, and have no severe unresolved bugs (or design flaws) discovered during the review.
