What web filtering strategy provides granular control over web traffic and ensures policy enforcement even off the corporate network?

Agent-based filtering is a strategy that allows organizations to have significant control over web traffic and ensures that security policies are enforced regardless of whether users are connected to the corporate network or working remotely. This is achieved by deploying security agents on user devices that monitor and filter web access based on predefined policies.

With agent-based filtering, organizations can enforce consistent security measures across various environments, including on-site, off-site, or hybrid, by requiring the agent to be active on the device. The agent can inspect web requests, evaluate them against the security policies, and act accordingly, maintaining security posture even when the device is outside the corporate perimeter.

This approach provides advantages like real-time monitoring, adaptability to changing user locations, and the ability to apply specific filtering rules tailored to different user roles or locations, thus helping to mitigate risks related to remote work and enhancing overall security management.

Other strategies, while useful for web filtering, may not offer the same level of control or enforceability outside of the corporate network. For example, proxy-based filtering often relies on routing traffic through a centralized server, which may not be applicable for off-network users without a VPN. DNS filtering can block requests based on domain names but might not provide granular control over specific content within web traffic. IP-based
