1、As organizations rapidly adopt hybrid work models and SaaS applications,many security teams have turned to Security Service Edge(SSE)solutions to enforce consistent access controls and data protections across distributed environments.Yet despite their widespread deployment,SSE platforms face mountin

2、g challenges in visibility,control,and effectivenessespecially at the“last mile”of user interaction within the browser.This paper is written for CISOs,security architects,and IT leaders seeking to understand these limitations.It is structured in two parts:the first explores architectural gaps in SSE

3、 design and operation,and the second examines real-world security use case failuresranging from GenAI data leakage to shadow SaaS and browser extension threats.I|By reading it,readers will gain a clear understanding of where SSE solutions fall short,why these gaps persist,and how organizations can c

4、omplement them with browser-level controls to achieve robust,end-to-end security.Executive SummaryCISO RecommendationsAugment SSE with browser-native controls to close last-mile security gaps.SSE platforms lack visibility into in-browser user actions and are blind to threats like copy/paste of sensi

5、tive data,unauthorized file uploads,and malicious extensions.CISOs should deploy secure enterprise browsers or lightweight browser security agents on managed endpoints to gain granular,session-level control over user activity within SaaS and web environments.Conduct a latency and performance audit b

6、efore full SSE rollout.Before scaling SSE across the organization,assess latency implications across geographies and application types.Identify performance bottlenecks introduced by PoP proximity,SSL decryption,and traffic inspection overhead.Where necessary,prioritize regional PoP placement or hybr
