Eset is an integrated product and uses all its all its components in various combinations in malware detection. In this case, Web access protection will interface with real-time protection for malware sigs., blacklists, etc.. Finally when you disable Eset's real-time protection, Windows Defender on Win 10/11 should immediate start up and set itself as Windows real-time protection. Eset Web access protection is designed to interface with Eset real-time protection; not WD real-time protection. Bottom line - you were actually testing WD's web access protection which in reality, doesn't exist.
