SASE has been dubbed the ‘security trend of the decade’ by Security Magazine.
Beyond being recognized as a security model for the hybrid workforce, SASE is fast becoming a force in addressing organizational and IT security challenges while also providing a suitable environment for efficiency and productivity.
In the wake of the pandemic, experiencing uninterrupted network access was a major concern for businesses newly testing the remote system. But several months after, businesses are beginning to prioritize secure long-term solutions over emergency patchwork measures.
What has changed?
The pandemic saw two major driving themes: work-from-home and accelerated digital transformation. They have grown over the past months to become a major area of focus for organizations and corporate IT departments.
SASE began in the SD-WAN market, making management and deployment of company branch network connections efficient through software-defined techniques — a development driven by the end-user.
Today, cybersecurity remains a major dynamic challenge with its area of expertise for the foreseeable future. But then, the SASE security framework comes in as a better approach to integrate security into enterprises’ networks.
What is SASE Security? A secure access service edge (SASE) is a method of delivering security controls and a wide area network (WAN) as a single-source connection and cloud computing service instead of through a data center. Security is based on real-time context, digital identity, and the set of rules to aid compliance to the use of company resources.
Challenges That SASE Addresses
Even in a ‘post-pandemic era,’ businesses have chosen to retain the hybrid work pattern, with some employees working from home. Usually, users tunnel in a single location through a VPN where policies and entitlements can be implemented centrally. But instead, the typical medium-sized business conducts multiple SaaS applications day-in-day-out while requesting access to other operational and administrative resources internal file-sharing systems.
However, this approach has been shown to characterize a network point that impairs user experience and requires huge investment in inspection devices to access and scrutinize network traffic.
This challenge is being addressed by the emergence of Secure Web Gateways and next-generation Firewall as a Service vendor, delivering the inspection engines in vital regional PoP sectors and implementing the Cloud Access Service Brokers (CASB) to secure the cloud environment.
Another challenge addressed is how users can reconnect to a corporate network at their homes or elsewhere.
SASE’s development is geared towards meeting the goal of an end-user with the Zero Trust component.
So, as long as remote workers, employees, or hybrid users can ascertain their connecting device and confirm their identity, they can be located anywhere on the planet and still fulfill their employee roles. A trusted user will only be able to access resources they need per time and will not be able to establish a connection elsewhere which is often performed by a software-defined perimeter (SDP).
More so, while traditional VPN solutions centralize all inspection points, a SASE model will distribute the checkpoints across diverse regions, enhance network efficiency, and ultimately address the management complexity of the components as distinct point solutions.
SASE provides an established and centralized cloud-based setup that helps boost control access and visibility access to these systems, which can be orchestrated and regulated in the cloud with distributed policy-setting at the network edge.
Key Trends in The SASE Market
The SASE market is responding to the constant demands of the enterprise market and offering multi-layered drivers focused on consolidating and integrating security and network tools. Here are some key trends in the SASE market currently.
1. SASE Means Remote And Office Connectivity
While many network users have chosen to work fully from home, some companies gradually shift towards the traditional office work pattern. However, remote workers and hybrid workforce are considered in the SASE provision.
SASE is designed to support work systems from anywhere. Technology vendors that lack remote access can search for them to make up better reporting and security capabilities.
2. Strong Trend In Consolidating and Integrating Security Functions On the SASE Model
End users seek better network and cloud security tools to accommodate the mobility of end-users, security threats, and increased access to cloud applications.
3. SASE Architecture Addresses The Demand For More Global Cloud-Based Security Architectures
While some vendors address this with different options and solutions, virtually all of them are diving into flexible service-based platforms that can be cloud-delivered, delivered to edge devices, or both.
4. Vendors and End Users Have Common SASE Interest
Integration, cloud computing, and network security are aligned interests of end-users and the efforts of technology vendors to drive more value across incorporated cybersecurity products portfolios.
In a nutshell, SASE is the security trend of the decade. The wave of technology at this time requires the features of this security architecture, which will also be of benefit in integrating solutions that are appealing to organizations desiring to create a unified security strategy and address multiple security challenges at once.
