Why is SASE essential for any security strategy?

In recent years, companies and their technology teams have been amidst the most significant change: remote work, which implies coordinating and ensuring that employees continue to obtain equally secure applications and access to new security techniques included in the cloud.

In the process, companies have realized that their physical network and security infrastructure must evolve to protect a less physical and much more digital environment.

For this reason, new, more agile and more secure technologies are being created that allow employees to work without worrying about the speed and agility of the response of their applications.

Gartner created the SASE (Secure Access Service Edge) concept, which was defined as a framework that combines network security functions (such as CASB, SWG, and ZTNA) with WAN capabilities (that is, SD-WAN) to support the dynamic, secure access organizations need.

SASE is a new suite of technologies that includes SD-WAN, CASB, SWG, CASB, FWaaS, and ZTNA as core capabilities, which are able to identify sensitive data or malware and decrypt content at line speed with continuous monitoring of sessions, increasing levels of trust.

SASE is essential for any security strategy, why?

SASE was created precisely to meet these new demands and offer companies security and efficiency in dealing with this Hybrid Multicloud universe.

Gartner believes that SASE is the vision of a future secure network model for enterprises and predicts that this concept will become the new security standard in the coming years, with at least 60% of enterprises adopting explicit SASE strategies until 2025.

Therefore, according to Gartner, security and risk management leaders responsible for infrastructure security should develop a roadmap for adopting SASE features and offerings.

Benefits of Secure Access Service Edge Software

 If we talk about protection, the SASE Security layer has benefits such as:

  • Cloud Access Security Broker: CASB is software hosted in the cloud or local software or hardware that acts as an intermediary between users and cloud service providers.
  • DNS sec: Public and private domain server traffic security for known and unknown threats.
  • ZTNA: Concept of Zero Trust Access is a cloud-based service that personalizes users’ access to only the specific applications they need.
  • FWaaS is a firewall delivered as a cloud-based service that allows customers to partially or fully move security inspection to a cloud infrastructure.

Not just Cloud

Generally speaking, SASE is a cloud-based service that provides access to cloud-based resources, secure communication between remote users, and secure device protection. However, in some situations, organizations may need a combination of physical and cloud-based solutions to ensure SASE is functioning properly.

By combining physical and cloud-based elements, SASE is also easier to extend deep into the network rather than relying on an entirely different system at the edge. 

A secure SASE connection can seamlessly integrate end-to-end protection with critical solutions that rely on hardware, such as network segmentation and compliance requirements that a cloud-only approach cannot address.

The future of SASE

Businesses have found out that they must provide consistent, secure, and globally available access to applications and services, regardless of where users are—whether they are employees, customers, or partners—or what devices they are using.

The secure access service offers companies a completely new model for connecting users and devices that is fast and flexible, simpler and more secure. We believe that SASE will provide the speed and agility necessary for businesses to transform into the digital future.
