SASE, in brief: a modern network for a modern world

by | Jun 9, 2025 | Blog

SASE (pronounced “sassi”) is an entirely cloud-native network model that merges two essential pillars:

  • 🌐 Intelligent connectivity with SD-WAN-like functions
  • 🔐 Advanced security, such as ZTNA, DNS filtering or TLS inspection

All delivered as a service in the cloud, with a single, centralized console. The aim? To give your employees secure access to their tools, wherever they are, and whatever their device.


Why traditional models no longer suffice

The classic network is office-centric: VPN, physical firewalls, and a central datacenter. But today :

  • Teleworking has become permanent
  • Mobile devices are everywhere
  • Applications in the cloud
  • And cyberthreats are evolving at breakneck speed

This rigid model slows innovation, reduces productivity, and leaves too many blind spots on the safety front.


SASE = simplicity + safety + performance

Adopting a SASE architecture allows you to :

  • Replace VPN: secure access per user, no permanent tunnel
  • Eliminate physical SD-WAN: intelligent routing to cloud applications
  • Centralize security: filtering, inspection, access control… all integrated in the cloud

And best of all: you have real-time visibility of everything that’s happening, in every branch or remote device.

Differences And Similarities Between SASE And SD-WAN

📱 And what about mobile devices?

This is where SASE really shines.

Phones, tablets and out-of-office laptops represent the biggest security challenge today. VPN is slow, unreliable and often misused on mobiles.

With SASE :

  • Devices connect directly to the nearest PoP (point of presence)
  • Security is applied according to context: identity, device, location
  • The user doesn’t have to do a thing: access is fluid, fast and protected.
  • IT sees everything in real time: connections, threats, applications in use

The result? Productivity without compromise, safety without complex configuration.


Fortinet: making SASE accessible to SMEs

Until recently, SASE was reserved for large companies. Fortinet has changed all that with its FortiSASE Starter Kit, designed for SMEs:

  • Accessible to 10 users or more
  • Includes Secure Private Access (SPA), to connect every user securely without VPN tunnels
  • Compatible with your FortiGate 120G+ firewalls
  • Modular and scalable with easy-to-manage co-term SKUs
  • Managed via FortiCloud, with visibility over users, applications and policies

In short, a SASE solution on a human scale, without heavy infrastructure or huge budgets.

FortiSASE - Expansion Bundle

Where SASE makes all the difference

💼 Hybrid or teleworking employees

Direct connection to tools (Teams, M365, etc.), without VPN. Fast, secure, frictionless.

🏪 Branches or franchises

No need for a site-to-site VPN. Each site connects to the Fortinet cloud. Uniform security, simplified configuration.

📱 Mobile users

Regardless of location or network, security is applied automatically. Less risk, less technical support.


And the FortiGate, do we keep them?

Absolutely. FortiGate continues to play an important role:

  • On main sites: network segmentation, Wi-Fi, local resources
  • In hybrid environments
  • As a relay for certain on-site safety policies

But for everything that’s nomadic, mobile or cloud-based, FortiSASE takes over, and everything is managed in a unified way.


In a nutshell

SASE is the modern answer to modern challenges.
Fortinet guarantees that even SMEs can adopt it without financial stress.

By combining safety, performance and simplicity, SASE enables :

  • abandon VPNs
  • eliminate complex interconnections between sites
  • better secure mobile devices
