The Firewall Isn't Blind — It Just Needs to See Inside the Session
Summary: The article argues that enterprise work has moved into HTTPS browser sessions on port 443, where firewalls see only an encrypted connection and cannot distinguish a ChatGPT prompt containing customer PII, a credential-harvesting browser extension, or a SaaS file transfer moving data out. It says Security Service Edge was built to close that gap through CASB, SWG, DLP and browser-level controls, but that full SSE deployments require replacing or modifying infrastructure, rerouting traffic, deploying endpoint agents and reconfiguring identity systems in multi-month projects, so adoption has lagged the problem.
Key Takeaway: The article states that enterprises able to absorb an 18-month SSE deployment are not the majority, leaving security teams defending session-level threats with network-level visibility in the interim. It also notes that traditional infrastructure can only block an AI tool entirely or allow it entirely, which leaves prompts containing sensitive data, downloaded responses and saved AI-generated content outside policy control.
