A forward proxy with content filtering capabilities would allow the administrator to enforce a content filtering policy, blocking access to specific sites as per the institution's guidelines. Concurrently, it would cache frequently accessed content, speeding up subsequent access for users. A reverse proxy, while commonly used for load balancing and SSL offloading, does not typically provide content filtering. An SSL/TLS proxy can decrypt and inspect SSL/TLS traffic but does not inherently provide content caching. A VPN service primarily provides remote access and encryption, which are not aligned with the stated requirements.
