5G SASE- Key to Security Access

Executive Summary

Networking and cyber security have changed dramatically in the past few years. The rising remote working culture due to the COVID-19 pandemic, coupled with the growing push of company data and infrastructure into the cloud, promoted many enterprises to outline a new approach to networking and security of the data. SASE, security access service edge, helps companies to install security at edge networks where the employees are located. SASE delivers end-to-end security, telemetry, and visibility for 5G infrastructure and related services. SASE frameworks were designed by Gartner to identify the features required to deliver device and application security to the end-users.

Factors That Are Driving the Market Growth

  • Adoption of SaaS in the traditional on-premises network architecture backhauling SaaS to the data center was a complicated process as it worsens latency and increases network costs. Due to the rising prevalence of cloud environments, SASE allows organizations to move network security services from data centers to remote users.
  • Rising adoption of remote working culture due to the COVID-19 pandemic, remote working has become very common among organizations. Employees have now started working remotely, ensuring the security of networks through traditional VPNs is not feasible. The traditional type of VPN doesn’t provide granular security controls.
  • IT Team handles all the security features and updates or upgrades their infrastructure to tackle ransomware or other threats. This is a complex and time taking process that still often leaves many organizations open to zero-day threats.

Key Challenges of SASE

  • In a few cases, a standalone SASE cloud-based solution is not enough to fulfill all the requirements an organization may ask for. For example- when local security is needed to separate OT and IT at a branch location, in that case, a hybrid approach is taken into consideration to balance on-premises and cloud networking and security.
  • No single platform is superior to any other; different types of organizations have different needs, for which Gartner’s magic quadrant isn’t enough.  An all-in-one platform benefits from a single policy engine that combines policies for networking and security. However, it may come with some functional limitations compared to a best-of-breed solution approach.

Implementing SASE in the Current Cloud Environment

implementing sase

SASE is a unified fabric that combines networking service brokering, identity service brokering, and security as a service into one. One of the major issues facing many IT teams today is ensuring that security is applied uniformly across an increasingly scattered network. Most businesses rely on on-premises, cloud, or hybrid security, and they want to protect their existing investments. A business would need to examine best-of-breed integrations and solutions that can be scaled to consolidate and centralize the security posture based on SASE principles. Integrating individual security tools into a single, policy-driven service is one of the primary drivers for adopting the SASE approach. Following are the key benefits:

  • Access to enterprise-level security provides greater security.
  • Firewall management consolidation.
  • Improvement in application performance.
  • Improved internet communication security.
  • Adaptability to changing business requirements.
  • Remote employees and stand-alone locations can be deployed faster.
  • Improved links to regions that are expensive or difficult to reach.
  • Network & Security-as-a-Service/monthly subscription

Traditional network perimeters are being phased out in favor of more optimized, cloud-based networks with zero trust governance as a result of growing risks, increased competition, and new methods of working. In addition, IT and security teams must meet stringent business and security requirements, consolidate and optimize technology, and enable frictionless connection to a hybrid workforce, customers, and partner ecosystem.

traditional networking and sase model

Enabling and securing remote access is one critical scene in which the SASE technique thrives. The remote worker is effectively becoming the new branch office as more individuals work from home. SASE streamlines security management and company-wide governance by providing visibility over resources and the ability to apply a single set of policies to all users, regardless of their location or device.

Vendors have been rapidly innovating since the COVID-19 outbreak began, providing services and solutions to their SASE platforms. To boost connectivity speeds and dependability, leading SASE suppliers are increasingly collaborating with key cloud service providers such as Office 365 and Zoom, AWS, Google Cloud, as well as ISPs and other partners.


As hackers take advantage of the trend to remote and hybrid work, cyberattacks and threats have escalated, leading to a significant shift toward cloud-based security and SASE solutions. The SASE model solves the limits of traditional network designs by integrating networking and security in the cloud as firms allow their staff to access corporate resources remotely. As per the data from the survey done by Check Point® Software Technologies Ltd. In July 2021, organizations were more vulnerable to cyberattacks when they moved to remote working, according to 45 percent of all respondents. Finance (54 percent), utilities (52 percent), and manufacturing were the industries with the most cyberattacks (47 percent).
