As student devices increasingly began traveling home, the limitations of appliance‑based filtering became clear, particularly around scalability, reliability, and off‑campus protection. Large districts found these systems difficult to maintain and ineffective beyond the school network, often creating single points of failure. Cloud‑based web filtering offers a more flexible alternative, providing zero‑touch authentication through SSO, greater fault tolerance without reliance on local infrastructure, and consistent protection wherever devices are used.
