Today’s IT teams face a common challenge: how to securely enable the growing universe of roaming users, devices, and software-as-a-service (SaaS) apps without adding complexity or reducing end-user performance – all while leveraging their existing security investments. Likewise, users in remote and branch offices need the same level of network performance and security protection as users in central locations. IT must develop strategies to protect users – wherever they work and on any device they use – from a variety of threats, including malware infections, command-and-control callbacks, phishing attacks, denial-of-service attacks, unauthorized access, and unacceptable use, among others. It’s easy to be overwhelmed by the complexity — but we’re here to help!

This book examines the changing network and security landscape, gaps in the existing security stack, and the steps you can take to keep your organization safe and secure as your network evolves. We’ll share how these changes are paving the way to a new solution category: the Secure Access Service Edge (SASE), which delivers multiple security functions from the cloud.

In five short chapters, you’ll learn:

• Key networking and security trends and their associated challenges, along with different networking and security options to solve them
• How an SD-WAN architecture addresses modern networking challenges
• How a multi-function cloud-native security service complements SD-WAN and addresses modern security challenges

By the end, you’ll understand the newest trends in networking and security, know the toughest challenges that these changes bring, and how to set up your business for success today in the future.
