Sarcastically, albeit unavoidably, most third-party safety add-ons don’t begin up in Protected Mode, so another strategy is just as well up with as many non-security-related apps turned off, so that they don’t begin robotically while you log in.
You possibly can quickly flip off auto-starting background apps within the Settings > Normal > Login Objects menu.
