SASE: SD-WAN and security in one cloud strategy

A secure access service edge from one provider

What is SASE?

Secure Access Service Edge (SASE, pronounced “sassy”) defines a new category of solutions as “converged offerings combining WAN capabilities with network security functions.” These solutions consolidate a swath of network and security capabilities into a single cloud-based service from one provider. By uniting point solutions into one cloud platform, technology silos are broken and IT complexity is replaced by visibility and ease of management. The end result is a synergy across both IT domains; under the SASE model, network and security have officially come together.

SASE solutions include:

  • SD-WAN
  • Firewall as a Service (FWaaS)
  • Secure Web Gateway (SWG)
  • Cloud Access Security Broker (CASB)
  • Zero Trust Network Access (ZTNA)

SASE adoption has accelerated by 94% due to the need for digital services and remote work

SASE Buyer’s Guide

ZK Research explains how SASE unites SD-WAN with security and which considerations can help you navigate this emerging new market.

Network and security analytics all in one portal

In 2017, Masergy began building security analytics into our network services management portal. Clients immediately noticed greater visibility for performance optimization and accelerated security threat response. The client portal includes security features like:

  • Shadow IT Discovery: Automatically scans and identifies potential threats from cloud-based SaaS applications running on your network
  • Identity-Based WAN Analytics: Detailed per-user statistics across all applications are essential in developing a Zero Trust security strategy
  • Full network visibility for faster security investigation and response
    • East/west and north/south (server-to-server) traffic within the data center
    • Client-to-server traffic outside the data center network

SASE architecture really matters

“Be wary of vendors that propose to deliver [SASE] services by linking a large number of features via VM service chaining, especially when the products come from a number of acquisitions or partnerships. This approach may speed time to market but will result in inconsistent services, poor manageability and high latency,” warned Andrew Lerner, V.P. of Networking Research at Gartner, in his blog article introducing SASE.

It’s important to avoid patchworked SASE services, and the degree to which the underlying SASE architecture is standardized distinguishes seamless SASE platforms from mere solution sets where vendors have cobbled together parts and pieces. The key is to have one transparent ecosystem where all SASE capabilities share a common infrastructure for superior interoperability and visibility from edge to edge.

Solution providers typically use their own private network to serve as the underlying platform, and it’s here where Masergy’s underlying network architecture stands out.

  • Standardized SD-architecture: Masergy’s global, private network is entirely software defined, built on a ubiquitous SD-architecture around the world
  • Common infrastructure: Every newly added technology and application interoperates as equal partners on the same operating system
  • Transparent interoperability: One ecosystem delivers the visibility and centralized management needed to achieve superior performance
