SSE, SASE, and Zero Trust: Mastering Security Beyond Borders with Next-Gen Edge Technologies is the essential guide for securing the modern, cloud-connected enterprise. Covering the three most influential network security architectures of our time--Secure Services Edge (SSE), Secure Access Service Edge (SASE), and Zero Trust--this book demystifies how these technologies work, why they matter, and how to implement them effectively.
Whether you're modernizing a global enterprise, securing a remote workforce, or preparing for the next evolution of cybersecurity, this comprehensive resource delivers the clarity, strategy, and practical steps needed to build a resilient security foundation.
Written for IT leaders, cybersecurity professionals, network engineers, and students entering the field, SSE, SASE, and Zero Trust blends foundational knowledge with real-world design patterns, migration frameworks, and best practices. Youll learn how these solutions work individually--and how they combine to form a holistic, future-ready security architecture.
If youre looking for a single resource that ties together cloud security, network transformation, and Zero Trust principles, this is the guide youve been waiting for.
