Explanation

Content filters operate at Layer 7 (the Application Layer) of the OSI model and can inspect, parse, and block specific application-layer content - including dangerous or prohibited HTML tags (e.g., <script> tags used in XSS attacks). Standard firewalls typically operate at Layers 3–4 and cannot inspect HTML syntax. Routers operate at Layer 3 and handle packet forwarding, not content inspection. NIDS (Network Intrusion Detection Systems) detect threats but are not specifically categorized as HTML tag filters. Content filters are purpose-built for application-layer content control.
