In a world where employees work from anywhere and applications mostly run in the cloud, a traditional network with separate firewalls, VPNs and appliances falls short. A SASE infrastructure provides a modern, integrated foundation for both networking and security. From a single cloud platform, all your sites, remote workers and mobile users get secure and fast access to applications, wherever they run. What is a SASE infrastructure? How it works? When is it relevant for your organization? We answer your questions:

What is a SASE infrastructure?

SASE stands for Secure Access Service Edge. A SASE infrastructure is a cloud-based platform that brings networking and security together. Instead of separate solutions per location or data center, you move the intelligence to the cloud.

A SASE infrastructure typically combines:

SD-WAN for smart, application aware connectivity between sites and the cloud
Secure Web Gateway for safe internet access
Next Generation Firewall and Intrusion Prevention for advanced threat protection
Zero Trust Network Access for secure access to internal applications without traditional VPN
Cloud Access Security Broker for control over SaaS applications
Central management for policy, logging and reporting across all users and locations

The result is one coherent infrastructure for connectivity and security instead of a collection of separate point solutions.

Why a SASE infrastructure is becoming essential?

Many organizations recognize one or more of these challenges:

Employees work in a hybrid model and use laptops, tablets and smartphones
More and more applications run in the cloud or as SaaS
The classic office network with a central firewall has become a bottleneck
The operational overhead and complexity of separate firewalls, VPNs and proxies is increasing
Security must meet stricter requirements and regulations

A SASE infrastructure addresses these issues head on. Instead of sending all traffic through the headquarters, users and locations get a secure connection directly to a SASE platform. That platform provides inspection, policy enforcement and optimal routing to the internet, cloud and data centers.

How a SASE infrastructure works in practice?

A modern SASE infrastructure usually consists of the following building blocks:

1. Edge connectivity

Physical or virtual SASE or SD WAN devices at sites
Clients or agents on laptops and mobile devices for remote users
Tunnels from data centers and cloud environments to the SASE platform

2. Cloud-based SASE platform

Global network of points of presence or nodes
Inspection of all traffic: web, applications and internal services
Policy enforcement based on identity, device, location and application

3. Central management and monitoring

One cloud console for configuration, policies and segmentation
Real-time visibility into traffic, performance and security events
Reports for compliance, audits and management

Users always connect to the nearest SASE node. From there, traffic is securely and efficiently routed to the right destination. This improves both performance and security.

Benefits of a SASE infrastructure for your organization

A well designed SASE infrastructure delivers clear business benefits:

Consistent security for all users. Whether someone works in the office, at home or on the road, everyone is covered by the same security policy.
Better performance for cloud and SaaS. Traffic no longer has to detour through a central data center. Direct, secure access via the SASE platform reduces latency.
Less complexity and operational overhead. Fewer separate appliances, fewer ad hoc VPN solutions and fewer custom configurations. You manage policies centrally.
More scalable and future proof. New branch, acquisition or growth in remote work. A SASE infrastructure scales with you.
Stronger security and Zero Trust. Access is based on identity and context instead of only network segments. This aligns with a Zero Trust architecture.

SASE infrastructure and SD WAN: how do they relate

SD WAN and SASE are often mentioned together but they are not the same.

SD WAN focuses primarily on smart, software defined WAN connectivity between locations and the cloud
SASE combines SD WAN with extensive security services in a single cloud platform

In practice, SD WAN is often a component of a broader SASE infrastructure. Elite Networks supports organizations that:

Already use SD WAN and want to evolve to a full SASE environment
Want to move directly from a traditional WAN and separate firewalls to SASE
Want to rationalize and modernize an existing firewall and VPN landscape

SASE infrastructure and Zero Trust

A SASE infrastructure is an important building block for a Zero Trust strategy. Instead of implicit trust inside the internal network, access is determined per user, device and application.

Key Zero Trust principles that show up in a SASE infrastructure include:

Verifying identity and device for every access request
Least privilege access to applications and data
Continuous inspection of traffic, regardless of location
Segmentation based on applications and user groups

For organizations with both IT and OT environments, this helps to better isolate production environments from office IT without disrupting operations.

When is your organization ready for a SASE infrastructure?

A SASE infrastructure is particularly interesting when:

You have multiple offices, warehouses or production sites
There is significant hybrid or remote work
A large part of your applications runs in the cloud or as SaaS
Your current VPN and firewall environment is complex and hard to manage
Your security requirements are increasing due to growth, compliance or regulations

Elite Networks works with organizations in sectors such as:

Manufacturing and logistics with a mix of OT and IT
Education with high demands on digital safety and scalability
Professional services with heavy cloud usage and hybrid work

FAQ about SASE infrastructure

What is a SASE infrastructure?
A SASE infrastructure is a cloud-based combination of networking and security services. Instead of separate firewalls, VPNs and proxies, you use one integrated platform that delivers SD WAN, secure access, web security and Zero Trust capabilities for all your users and locations.

How is a SASE infrastructure different from a traditional network with VPN and firewall?
In a traditional network, users and locations usually connect through a central firewall or data center, which adds extra hops and complexity. In a SASE infrastructure, users and locations connect directly to a cloud platform that handles both security and routing. This is more scalable, more secure and better suited for cloud and hybrid work.

Is a SASE infrastructure suitable for mid sized organizations?
Yes. SASE is not only for large enterprises. Mid sized organizations with multiple sites, significant cloud usage and hybrid work benefit from the simplicity and central control of a SASE infrastructure. Elite Networks regularly helps organizations that want to move from a traditional WAN to SASE.

Which technologies does Elite Networks use for SASE infrastructures?
Elite Networks works with Cato Networks as a cloud native SASE platform and with Fortinet for integrated networking and security solutions. Based on your situation and requirements, we advise an architecture and technology stack that fits your organization.

How long does it take to implement a SASE infrastructure?
That depends on the number of locations, the current environment and the desired scope. An initial phase with a pilot site and a group of remote users can often be set up within weeks. A full migration of all sites and users usually takes a few months. We work in phases to safeguard business continuity.

What does a SASE infrastructure cost?
The cost of a SASE infrastructure depends on factors such as the number of users, locations, bandwidth and required services. Often, investments shift from hardware and separate licenses to a predictable subscription model. Elite Networks can provide an estimate based on a short assessment of your environment.
