AV-Comparatives offers certification for parental control software, evaluating products against stringent criteria. Each solution is tested with 1,000 URLs containing adult content and 200 child-safe URLs. Starting in 2025, to achieve certification, a product must block at least 95% of adult websites, have zero false positives on child-friendly websites, and be free from significant unresolved bugs or design flaws.
