Episode 50 — Proxies, Gateways, and CASB Basics

This episode focuses on the middlemen of modern connectivity—devices and services that inspect, control, and secure traffic before it reaches its destination. You’ll learn how web proxies enforce acceptable use policies, filter content, and provide caching for performance and control. We explain how secure email and web gateways prevent data loss, block malicious attachments, and sanitize links to reduce exposure. The episode also introduces Cloud Access Security Brokers (CASB), which extend these controls to SaaS applications by inspecting API traffic and applying the same policy logic used on-premises.Listeners will see how these technologies enable visibility into encrypted and cloud-based traffic that traditional perimeter tools can’t reach. We discuss integration challenges like SSL inspection, privacy considerations, and how to balance depth of inspection with latency. The conversation ties directly to exam questions about layered defenses and to real-world strategies for enforcing consistent security across hybrid environments.
