What is SASE and how is it revolutionizing the security of your corporate network?

With the widespread adoption of remote working, the growing use of SaaS applications, and the disappearance of the traditional network perimeter, conventional security architectures are no longer sufficient. The Secure Access Service Edgemodel, or SASE, meets these new requirements by natively merging network and security functions into a unified, cloud-native approach.

Scalair supports companies in the evolution of their infrastructure. By integrating modern solutions such as SASE, adapted to hybrid environments and new digital uses.

SASE: an approach where the network becomes a security platform

Previously, connectivity and protection were managed by separate (and often siloed) solutions. The concept of SASE, defined by Gartner, is based on the unification of connectivity and security services in a cloud architecture. It involves converging the following functions in a distributed model:

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

The goal is to provide secure access to resources, regardless of where users or applications are located, while ensuring centralized visibility and control.

Why SASE is essential in modern environments

Companies can no longer rely on a partitioned architecture between internal networks and the Internet. Employees work remotely, applications are mostly in SaaS mode, and data circulates outside the traditional perimeter.

The SASE model addresses these challenges by:

Security natively integrated into the network flow

Security services are delivered from the cloud, enabling the same security policies to be applied to remote users, branch offices, and online applications.

Identity- and context-based access (Zero Trust)

Thanks to the principle of Zero Trust, access is granted based on the user's identity, device, location, and risk level. This significantly reduces the exposure surface.

Centralized and scalable management

Configuration, monitoring, and policy enforcement are all done from a single console. The SASE model easily adapts to changes in the number of users, sites, or applications.

Scalair's positioning on networks and modern security

Scalair supports SMEs and mid-market companies in modernizing their IT infrastructure by integrating scalable and secure network solutions. The company offers managed services based on technologies compatible with the SASE model. This is particularly useful in multi-site, cloud, or remote working environments, or for companies with mobility or international deployment challenges.

Projects carried out include:

• Implementation of secure cloud infrastructures with traffic segmentation
• The integration of ZTNA and cloud access control
• Support for network transition with a focus on performance and security.

Scalair acts as a partner in building an aligned network architecture where cybersecurity is no longer an add-on option, but the very foundation of connectivity.

The SASE model is establishing itself as a concrete response to the challenges posed by the digital transformation of businesses. It enables security and connectivity to be unified in a world where there should no longer be any boundaries.

By integrating SASE components into its managed services offerings, Scalair enables companies to secure their access, data, and usage, while improving the overall performance of their information systems.
