Hello,
Thank you for your question and reaching out. I can understand you are having query\issues related to Content filtering.
Web content filtering is part of the Microsoft Defender for Endpoint solution and is fully integrated with the web protection capabilities. Your business may monitor and control access to websites based on the types of content they contain thanks to online content filtering. Several of these websites may be troublesome due to compliance rules, bandwidth usage, or other issues—even if they are not malicious.
Hence apart from Firewall or Physical appliance you can use Microsoft Defender for content filtering.
