What are two reasons why organizations and individuals use web filtering?

Organizations and individuals use web filtering primarily to prevent network congestion and to preserve employee productivity, making this the correct answer.

Preventing network congestion is crucial because unrestricted access to the internet can lead to bandwidth hogging by non-essential sites and applications, which can ultimately slow down network performance for everyone. By filtering specific websites, organizations can manage the bandwidth more effectively, ensuring that necessary applications and services function optimally.

Preserving employee productivity is equally important. Access to distracting websites — such as social media, streaming services, or online gaming — can significantly reduce the amount of work employees accomplish during their hours on the job. Web filtering helps maintain focus by limiting access to these distractions, allowing employees to stay on task and contribute more effectively to their roles.

While other options presented valid points, such as blocking malware or securing personal data, the primary motivations for web filtering in a workplace setting often center on productivity and the management of network resources.
