Introduction to Secure Access Service Edge (SASE) Architecture: Revolutionising Network Security

In recent years, various innovative security solutions have emerged because of the fast-changing network security trends. Remote work and cloud computing add complexity to existing network infrastructure which demands more flexible and dynamic security measures. SASE is an innovative architecture that combines network security and connectivity into one solution, meeting the needs of businesses. The SASE architecture delivers a new level of security and convenience to business environments. It provides a secure VPN connection for remote users, as well as access to cloud services such as Office 365.

In this blog post, we will talk about Secure Access Service Edge, its architecture, and how it has revolutionised network security trends.

What is SASE?

SASE is a term by Gartner for a combined architecture that provides secure and user-friendly access to systems, applications, and data. This is regardless of the user’s location or the device they are using. Secure Access Service Edge is a converged architecture that acts as a single solution combining networking and security. Secure Access Service Edge architecture has SD-WAN, SWG, FWaaS, ZTNA, and more. This combination is great for businesses wanting to improve their cybersecurity and handle spread-out IT systems.

SASE Overview

SASE combines the capabilities of multiple components. Let’s break it down to understand the Secure Access Service Edge architecture better.

• SD-WAN: It enhances network performance and agility by separating control and data planes in networking devices. This separation is a crucial component of SASE. It also prioritises and routes traffic based on application requirements, creating a more efficient and flexible network.
• Secure Web Gateway (SWG): SWG filters internet traffic to block malware and enforce company security policies. With an emphasis on real-time protection, SWG enhances the security of data and users across the network.
• Firewall-as-a-Service (FWaaS): FWaaS delivers firewall functionality through the cloud, enabling a scalable and accessible solution. This approach simplifies firewall administration and provides consistent security policies across various locations and devices.
• Zero Trust Network Access (ZTNA): ZTNA implements the principle of “never trust, always verify” to maintain secure access control. It continuously authenticates and authorises users, devices, and applications, thereby minimising the attack surface and reducing potential risks.

SASE vs. Traditional Security

Traditional security architectures often rely on a rigid perimeter-based approach, where traffic must pass through a central firewall. This method is no longer considered effective. The reason for this is that more people are now working remotely and using cloud services. As a result, the risk of exposure has increased. The Secure Access Service Edge security system follows the Zero Trust Network Access (ZTNA) principle. This principle provides detailed access control and ongoing authentication. The purpose is to minimise the risk of attacks. ZTNA leverages technologies such as micro-segmentation and intelligent endpoint protection to enhance security effectiveness, reliability, and efficiency.

SASE is paving the way for a new era in network security, offering a more agile and adaptable approach. Secure Access Service Edge combines security features into one solution, allowing organisations to apply consistent security policies across locations and devices instantly.

Features of SASE

• Integrated Security Services: SASE integrates multiple security services such as SD-WAN, firewall as a service (FWaaS), secure web gateways (SWG), data loss prevention (DLP), and more into a single platform. This integration streamlines security management, reduces complexity, and ensures consistent policy enforcement.
• Cloud-Native Architecture: With its cloud-based infrastructure, Secure Access Service Edge allows organisations to deploy security services quickly and efficiently. Its cloud-native nature enables scalability, flexibility, and accessibility across various locations and devices.
• Zero Trust Framework: Secure Access Service Edge operates on a Zero Trust security model, which verifies the identity and security posture of users and devices before providing access to resources. This approach reduces the risk of unauthorised access and lateral movement within the network.
• Edge-Centric Security: With a focus on the network edge, Secure Access Service Edge offers security services closer to users and applications. This proximity ensures faster response times, reduces latency, and improves overall user experience.

Benefits of SASE

• Enhanced Security Posture: By incorporating a comprehensive set of security services and a Zero Trust model, SASE strengthens an organisation’s security posture, mitigating risks and safeguarding against emerging threats.
• Improved User Experience: SASE’s edge-centric approach and cloud-native architecture lead to faster and more reliable access to applications and data, enhancing the overall user experience.
• Cost-Efficiency: Integrating security services into a single platform reduces operational costs associated with managing various security solutions and ensures better resource utilisation.
• Agility and Flexibility: Secure Access Service Edge’s agility allows organisations to adapt quickly to changing business needs, scale resources on demand, and deploy security services wherever they’re
