What are the key components of SASE architecture?

SASE architecture comprises three core components: SASE Network (including SD-WAN), SASE Security (encompassing FWaaS, SWG, CASB, ZTNA, and anti-malware solutions), and Lifecycle Services (Aryaka’s unique addition). This cloud-based framework integrates networking and security functions, offering scalability, simplicity, and cost-efficiency. It also incorporates SSE (Secure Services Edge) for robust edge protection, making it a comprehensive solution for modern enterprise security needs.

Comprehensive Overview of the SASE Framework

Core Components of SASE

The SASE (Secure Access Service Edge) framework is primarily built on two foundational components: SASE Network and SASE Security, both integrated within a cloud-based model. This integration harnesses the cloud’s full potential—scalability, simplicity, and cost-efficiency—applying these advantages to both networking and security. This cloud-centric approach simplifies deployment and consumption, making it suitable for enterprises of varying sizes.

Detailed Breakdown of SASE Components

  1. SASE Network: This component includes SD-WAN (Software-Defined Wide-Area Network), which enhances connectivity, optimizes application performance, and facilitates efficient multi-cloud access.
  2. SASE Security: This encompasses several advanced security solutions:
    • FWaaS (Firewall as-a-Service): Filters unwanted traffic based on security rules.
    • SWG (Secure Web Gateway): Ensures safe internet access and compliance with corporate policies.
    • CASB (Cloud Access Security Brokers): Monitors and secures cloud environments.
    • ZTNA (Zero Trust Network Access): Grants access based on strict identity verification.
    • Antivirus and Malware Inspection: Protects against malicious software and threats.

These components are seamlessly blended to deliver a unified, cloud-based infrastructure where networking and security are interdependent, enhancing both functionality and management.


Aryaka’s Unified SASE Architecture

Aryaka’s Unified SASE as a Service is a comprehensive solution designed to deliver performance, agility, simplicity, and security without tradeoffs.

2. Aryaka Zero Trust WAN

Aryaka’s Zero Trust WAN operates over a global private network, enhancing security and performance from the initial to the final mile of connectivity. It connects Aryaka Point of Presence (POP) locations through redundant and dedicated links, offering a private core backbone with specific bandwidth allocations for inter-office traffic. This setup reduces jitter, ensures deterministic throughput and latency, and provides secure, fast, and reliable access to cloud and SaaS applications globally. By leveraging a private backbone, it minimizes the attack surface by avoiding public Internet backbones for inter-POP traffic, thus significantly enhancing security.

3. Aryaka Services

Under its Unified SASE as a Service, Aryaka offers a broad array of integrated services including Unified Policy, Network Security, SD-WAN, Application Acceleration, WAN Optimization, and Observability services. Additional offerings include Secure Remote Access, Next-Gen Firewall-Secure Web Gateway, Anti-Malware and IPS, Managed Firewall Services, Last Mile Services, and Professional Services. Aryaka’s customer portal provides monitoring, insights, alerting, and reporting capabilities in a real-time, co-managed portal, allowing customers to choose their preferred service delivery method.

4. Aryaka Delivery

Aryaka delivers its Unified SASE services through a combination of its single-pass architecture and a global private core network. This approach consolidates traditionally separate products like SD-WAN, Next-Gen Firewall, Secure Web Gateway, IDPS, and Observability services into a unified platform. Enterprises can connect to Aryaka’s cloud-connected, software-defined network and security architecture as a service, enabling rapid deployments and instant application of network and security policy changes across the network. Aryaka’s solution is tailored to provide performance, agility, simplicity, and security, offering flexible delivery options to accommodate the unique needs of each organization.


Understanding SSE and Its Role in SASE

What is SSE?

SSE (Secure Services Edge) is a subset of the broader SASE (Secure Access Service Edge) framework, specifically focusing on the security aspects. Defined by Gartner in 2021, SSE combines various security services that can be integrated with network services like SD-WAN to form a comprehensive security solution. Essentially, SSE represents the concentrated security component within the SASE architecture, ensuring robust protection at the network’s edge.

Core Components of SSE

SSE operates at the critical juncture where the enterprise network meets the internet or cloud services, deploying security measures to shield against external threats. The primary components of SSE include:

  1. Firewall: This network security system scrutinizes and manages incoming and outgoing network traffic based on established security rules, acting as a barrier against unauthorized access.
  2. Secure Web Gateway (SWG): Provides web content filtering, malware protection, and URL filtering, safeguarding against web-based threats.
  3. VPN (Virtual Private Network): Facilitates a secure connection for remote users or sites to the enterprise network over the internet, encrypting data in transit to prevent interception.
  4. ZTNA (Zero Trust Network Access): Adopts a zero-trust security model where no user or device is inherently trusted. Access is granted strictly based on identity verification and need-to-know basis, enhancing security by minimizing potential internal and external threats.
  5. CASB (Cloud Access Security Brokers): Offers visibility and control over cloud services and applications, enforcing security policies to prevent threats like data leakage and malware.
  6. DLP (Data Loss Prevention): These solutions monitor and protect sensitive data from unauthorized access or transfer, whether in motion, at rest, or in use.

Importance of ZTNA in SASE

Aryaka’s implementation of ZTNA within the SASE framework underscores a shift from traditional perimeter-based security models to a more dynamic, zero-trust approach. This model necessitates rigorous verification of all users and devices before they can access network resources or applications, whether hosted on-premises or in the cloud. ZTNA ensures that access is securely confined to authorized entities, with all connections encrypted to safeguard against potential security breaches.

By integrating ZTNA with other SASE components like SWG, CASB, and SD-WAN, organizations can establish a robust security architecture. This architecture not only secures access to applications and services regardless of location or device but also aligns with modern cybersecurity practices that prioritize adaptive, identity-based security measures over traditional, perimeter-focused strategies.
