Fortinet SASE: The Ultimate Guide to Secure Access Service Edge Architecture in 2024

In today’s rapidly evolving digital landscape, organizations face unprecedented challenges in securing their networks while maintaining operational efficiency. The traditional network security model—centered around a defined corporate perimeter—has become obsolete as applications migrate to the cloud and users connect from anywhere. This paradigm shift has given rise to Secure Access Service Edge (SASE), a revolutionary framework that combines network and security functions into a unified, cloud-delivered service. At the forefront of this transformation stands Fortinet’s implementation of SASE, offering a comprehensive approach that addresses the security challenges of the modern distributed enterprise.

Understanding SASE Architecture: The Convergence of Networking and Security

SASE (pronounced “sassy”) represents a fundamental shift in how organizations approach network security. First coined by Gartner in 2019, SASE has quickly evolved from a theoretical concept to a practical solution for enterprises dealing with cloud migration, remote workforces, and edge computing. At its core, SASE combines wide-area networking capabilities with cloud-native security functions, delivering them as a unified service from the cloud.

Traditional network architectures relied on a hub-and-spoke model, where traffic from branch offices and remote locations was backhauled to a central data center for security inspection before being sent to its destination. This approach creates latency issues, especially for cloud applications, and struggles to scale with increasing traffic volumes. SASE addresses these limitations by moving security functions to the cloud, closer to users and applications, enabling direct and secure access regardless of location.

The Key Components of SASE Architecture

A comprehensive SASE solution encompasses several essential components that work in harmony to deliver secure access:

• Software-Defined Wide Area Networking (SD-WAN): Provides intelligent path selection, application-aware routing, and WAN optimization to enhance performance and reliability.
• Secure Web Gateway (SWG): Protects users from web-based threats by enforcing corporate policies and filtering malicious content.
• Cloud Access Security Broker (CASB): Secures cloud application usage by providing visibility and control over data and applications in the cloud.
• Zero Trust Network Access (ZTNA): Implements the “never trust, always verify” principle by granting access based on identity and context rather than network location.
• Firewall as a Service (FWaaS): Delivers next-generation firewall capabilities from the cloud, including advanced threat protection and traffic inspection.
• Network as a Service (NaaS): Provides global connectivity options through a cloud-native infrastructure.

The integration of these components creates a seamless security fabric that can adapt to changing business requirements while maintaining consistent protection across all users, applications, and devices. This unified approach eliminates the complexity and security gaps associated with managing multiple point solutions from different vendors.

Fortinet’s Approach to SASE: Unified Security and Networking

Fortinet’s implementation of SASE, known as Fortinet Unified SASE, stands out in the market due to its holistic approach that leverages the company’s comprehensive security portfolio.

The Fortinet Unified SASE solution is architected around three core principles:

1. Convergence of networking and security: Fortinet integrates its market-leading SD-WAN capabilities with a full stack of security services, eliminating the operational silos between network and security teams.
2. Single-vendor approach: By offering all SASE components from a single source, Fortinet reduces complexity, simplifies management, and ensures consistent protection.
3. Flexibility in deployment: Organizations can adopt SASE at their own pace, with options for on-premises, cloud, or hybrid implementations based on specific requirements.

FortiSASE: Cloud-Delivered Security Service Edge

At the heart of Fortinet’s SASE strategy is FortiSASE, a cloud-delivered Security Service Edge (SSE) solution that provides secure access to applications, data, and services for users regardless of their location. FortiSASE combines multiple security capabilities into a unified service, including:

• Zero Trust Network Access (ZTNA): FortiSASE implements a sophisticated ZTNA approach that verifies users and devices before granting access to applications. This continuous verification process evaluates factors such as user identity, device health, and behavior patterns to make access decisions.
• Secure Web Gateway (SWG): The integrated SWG functionality protects users from web-based threats by enforcing URL filtering, SSL inspection, and data loss prevention (DLP) policies.
• Cloud Access Security Broker (CASB): FortiSASE includes CASB capabilities to provide visibility and control over cloud application usage, protecting sensitive data and ensuring compliance with regulatory requirements.
• Firewall as a Service (FWaaS): The solution delivers enterprise-grade firewall capabilities from the cloud, including advanced threat prevention, intrusion prevention, and application control.

A key differentiator of FortiSASE is its underlying security engine, FortiOS, which provides consistent protection across all form factors. This unified operating system ensures that security policies and threat intelligence are applied consistently whether a user is connecting from a branch office, home network, or public Wi-Fi.

Technical Implementation of FortiSASE

From a technical perspective, FortiSASE leverages a global network of Points of Presence (PoPs) strategically located to minimize latency and optimize performance. These PoPs host the security services and connect to a high-performance backbone network that ensures reliable connectivity to both cloud and on-premises resources.

When a user attempts to access an application, the FortiSASE cloud service performs multiple security checks in real-time:

1. User authentication using multi-factor authentication (MFA) and integration with identity providers
2. Device posture assessment to verify compliance with security policies
3. Continuous risk assessment based on user behavior and environmental factors
4. Application of security policies, including URL filtering, malware scanning, and data protection
5. Encrypted tunnel establishment for secure application access

This process occurs transparently to the user, providing a seamless experience while maintaining strong security controls. The following code snippet illustrates a typical FortiSASE policy configuration:


config firewall policy
edit 1
set name "SASE-SaaS-Access"
set srcintf "virtual-wan-link"
set dstintf "virtual-wan-link"
set srcaddr "all"
set dstaddr "SaaS-Applications"
set action accept
set schedule "always"
set service "ALL"
set utm-status enable
set ssl-ssh-profile "certificate-inspection"
set application-list "default"
set ips-sensor "default"
set webfilter-profile "default"
set dnsfilter-profile "default"
set ssl-inspection "deep-inspection"
next
end


FortiOS: The Foundation of Fortinet’s SASE Implementation

The technical backbone of Fortinet’s SASE offering is FortiOS, the proprietary operating system that powers all Fortinet security products. FortiOS provides a common framework for policy management, threat intelligence sharing, and security automation across the entire Fortinet Security Fabric, including SASE components.

FortiOS enables several critical capabilities for SASE implementation:

Universal Policy Management

One of the greatest challenges in implementing SASE is maintaining consistent security policies across diverse environments. FortiOS addresses this challenge through its universal policy engine, which allows administrators to define policies once and apply them everywhere—from branch offices to cloud environments to remote users.

This unified approach to policy management significantly reduces the operational overhead associated with maintaining multiple security solutions. For example, a data loss prevention policy defined in FortiOS can be automatically applied to web traffic (via SWG), cloud applications (via CASB), and private applications (via ZTNA), ensuring consistent protection regardless of how users access sensitive information.

Advanced Threat Intelligence Integration

FortiOS integrates with FortiGuard Labs, Fortinet’s global threat intelligence network, to provide real-time protection against emerging threats. This integration brings several advanced security capabilities to the SASE framework:

• AI-powered threat detection: FortiGuard leverages artificial intelligence and machine learning algorithms to identify and block sophisticated attacks, including zero-day exploits and advanced persistent threats (APTs).
• Sandboxing: Unknown files can be automatically sent to FortiSandbox for detonation and analysis, protecting against previously unknown malware.
• Content disarm and reconstruction (CDR): Files are automatically sanitized to remove potential threats while preserving functionality.
• Real-time URL filtering: Web addresses are continually evaluated for malicious content, with categories updated in real-time.

The following example demonstrates how FortiOS integrates threat intelligence into security policies:


config firewall policy
edit 10
set name "SASE-Internet-Access"
set srcintf "internal"
set dstintf "wan1"
set srcaddr "all"
set dstaddr "all"
set action accept
set schedule "always"
set service "ALL"
set utm-status enable
set av-profile "fortiguard-based"
set webfilter-profile "block-malicious"
set ips-sensor "protect-client"
set application-control-profile "default"
set logtraffic all
set nat enable
next
end


Single-Pass Processing Architecture

A unique technical aspect of FortiOS is its Single-Pass Processing architecture, which allows multiple security functions to be applied to network traffic simultaneously. Unlike traditional approaches that require traffic to pass through separate security engines for each function (firewall, IPS, web filtering, etc.), FortiOS processes all security functions in a single pass, significantly reducing latency and improving performance.

This architecture is particularly beneficial for SASE implementations, as it enables complex security processing to occur in the cloud without introducing noticeable delays. For remote users accessing cloud applications, this means enterprise-grade security without sacrificing performance—a critical requirement for maintaining productivity in today’s distributed work environment.

SD-WAN Integration: The Networking Pillar of Fortinet SASE

While many SASE discussions focus heavily on security aspects, the networking component is equally important for delivering a complete solution. Fortinet’s approach to SASE leverages its industry-leading SD-WAN technology as the networking foundation, providing intelligent connectivity that complements the security services.

FortiGate Secure SD-WAN

Fortinet’s SD-WAN solution is built into the FortiGate next-generation firewall platform, providing integrated security and networking functions in a single device. This integration is a key differentiator in Fortinet’s SASE approach, as it allows organizations to deploy consistent security and networking capabilities across branch offices, data centers, and cloud environments.

FortiGate Secure SD-WAN delivers several critical capabilities for SASE implementations:

• Application awareness: The solution can identify over 5,000 applications and make routing decisions based on application type, user identity, and performance requirements.
• Automated path selection: Dynamic path selection automatically routes traffic over the best available connection based on real-time performance metrics.
• WAN optimization: Built-in WAN optimization techniques improve application performance by reducing bandwidth consumption and latency.
• Direct cloud access: Secure local internet breakout enables direct access to cloud applications without backhauling traffic to a central data center.

A key technical innovation in FortiGate Secure SD-WAN is its application-centric approach to traffic management. Rather than relying solely on traditional network metrics like packet loss and latency, the solution evaluates the actual user experience for specific applications. This is achieved through continuous monitoring of application performance and automated adjustments to routing decisions.

Consider this configuration example for Microsoft 365 optimization in a FortiGate SD-WAN deployment:


config system sdwan
set status enable
config zone
edit "virtual-wan-link"
set service-sla-id 1
next
end
config members
edit 1
set interface "wan1"
set gateway 192.168.1.1
next
edit 2
set interface "wan2"
set gateway 10.0.0.1
next
end
config health-check
edit "Office365"
set server "www.office.com"
set members 1 2
set sla-fail-log-period 600
set sla-pass-log-period 600
set protocol http
set port 443
config sla
edit 1
set latency-threshold 150
set jitter-threshold 30
set packetloss-threshold 2
next
end
next
end
config service
edit 1
set name "Office365-Traffic"
set mode sla
set dst "Microsoft365"
set src "all"
config sla
edit "Office365"
set id 1
next
end
set priority-members 1 2
next
end
end


Cloud On-Ramp Capabilities

A critical aspect of Fortinet’s SASE implementation is its cloud on-ramp capabilities, which provide optimized connectivity to major cloud service providers. This functionality is essential for organizations that have migrated applications to multiple cloud environments and need consistent performance and security.

Fortinet’s cloud on-ramp approach involves several technical components:

• Cloud connectors: Purpose-built integration with major cloud platforms (AWS, Azure, Google Cloud, Oracle Cloud) that automate the discovery of cloud resources and apply appropriate security policies.
• Virtual FortiGate instances: Cloud-native implementations of FortiGate that can be deployed within cloud environments to provide consistent security and networking services.
• API integration: Deep integration with cloud provider APIs to enable automated scaling, security policy enforcement, and traffic management.

This approach allows organizations to extend their SASE architecture seamlessly into cloud environments, ensuring that users have secure and optimized access to cloud-hosted applications. By deploying FortiGate instances in cloud regions close to where applications are hosted, Fortinet minimizes latency and maximizes performance while maintaining robust security controls.

Zero Trust Implementation in Fortinet SASE

Zero Trust Network Access (ZTNA) is a foundational component of Fortinet’s SASE architecture, implementing the principle that no user or device should be trusted by default, regardless of their location or network connection. This approach represents a significant departure from traditional perimeter-based security models and is particularly important in today’s distributed work environment.

FortiClient and Zero Trust Access

The client-side component of Fortinet’s ZTNA solution is FortiClient, an endpoint security agent that provides secure access to applications while enforcing security policies. FortiClient establishes secure, encrypted tunnels to application resources based on user identity and device posture, rather than network location.

From a technical perspective, FortiClient implements ZTNA through several key mechanisms:

• Micro-segmentation: Applications are hidden from unauthorized users, with access granted only after successful authentication and authorization.
• Continuous verification: User and device trust is continuously evaluated throughout the session, not just at initial connection.
• Least privilege access: Users are granted access only to specific applications they need, rather than to entire network segments.
• Device posture assessment: Security checks verify that endpoints meet security requirements before granting access.

The following FortiClient configuration example illustrates how ZTNA policies are implemented at the endpoint level:


<forticlient_configuration>
<zero_trust_access>
<enabled>1</enabled>
<sso_enabled>1</sso_enabled>
<server>sase.fortinet.com</server>
<port>443</port>
<certificate_validation>1</certificate_validation>
<on_connect>
<run_posture_check>1</run_posture_check>
</on_connect>
<applications>
<application id="1">
<name>Internal CRM</name>
<service_name>crm-app</service_name>
<description>Access to internal CRM system</description>
</application>
<application id="2">
<name>Financial Reports</name>
<service_name>finance-app</service_name>
<description>Access to financial reporting system</description>
</application>
</applications>
</zero_trust_access>
</forticlient_configuration>


Identity-Based Access Control

A core aspect of Fortinet’s ZTNA implementation is its sophisticated identity-based access control system. This system integrates with existing identity providers (such as Microsoft Active Directory, Okta, or Azure AD) to leverage established identity and access management frameworks while extending them with additional security controls.

The identity-based access control in Fortinet SASE operates at multiple levels:

• User identity verification: Authentication using multiple factors, including passwords, certificates, and biometrics.
• Role-based access control: Access policies based on user roles and responsibilities within the organization.
• Context-aware authorization: Access decisions that consider contextual factors like location, time, device, and behavior patterns.
• Continuous authentication: Ongoing verification throughout the user session rather than just at login.

This multi-layered approach to identity verification is critical for implementing true Zero Trust principles, as it ensures that access decisions are based on comprehensive information about the user and their environment. By continuously evaluating this information, Fortinet’s SASE solution can detect anomalous behavior and adjust access permissions accordingly, helping to prevent compromise even if credentials are stolen.

Security Service Edge: The Cloud Security Component

The Security Service Edge (SSE) represents the security pillar of SASE, focusing on cloud-delivered security services that protect users, devices, and data regardless of location. Fortinet’s implementation of SSE, part of its broader SASE strategy, provides comprehensive protection through a suite of integrated security services.

FortiSASE SSE Components

FortiSASE delivers SSE functionality through several key security services:

Secure Web Gateway (SWG)

The SWG component of FortiSASE provides comprehensive protection against web-based threats by monitoring and filtering HTTP/HTTPS traffic. From a technical perspective, the SWG functionality includes:

• URL filtering: Categorization of websites based on content and reputation, with policies to allow, block, or warn users about potentially dangerous sites.
• SSL/TLS inspection: Decryption and inspection of encrypted traffic to identify hidden threats, with granular controls to exempt sensitive categories (like financial or healthcare sites).
• Content inspection: Deep analysis of web content, including HTML, JavaScript, and multimedia, to detect and block malicious code.
• Browser isolation: Optional remote browser isolation for high-risk websites, executing web content in a secure cloud environment rather than on the user’s device.

The SWG capabilities are powered by FortiGuard’s web filtering service, which maintains a database of billions of URLs categorized into more than 90 categories. This database is continuously updated through a combination of automated crawling, machine learning analysis, and human verification, ensuring high accuracy in content categorization.

Cloud Access Security Broker (CASB)

The CASB functionality in FortiSASE provides visibility and control over cloud application usage, helping organizations secure sensitive data and ensure compliance with regulatory requirements. The CASB component operates in multiple modes:

• API mode: Integration with cloud service provider APIs to monitor data at rest, enforce data loss prevention policies, and detect misconfigurations or compliance violations.
• Proxy mode: Real-time monitoring and control of cloud application access, with the ability to enforce granular policies based on user, device, and data sensitivity.
• Shadow IT discovery: Identification and risk assessment of unauthorized cloud applications being used within the organization.

A key technical innovation in Fortinet’s CASB approach is its integration with the broader security fabric, enabling consistent data protection policies across on-premises and cloud environments. For example, a data loss prevention policy defined for sensitive customer information can be automatically applied to both internal file servers and cloud storage platforms like Box or Dropbox.
