Preparing for SASE: Key Factors and Strategies for a Successful Transition

May 31, 2024

The shift towards Secure Access Service Edge (SASE) architecture is a significant move for any organisation, especially in the dynamic digital landscape of Australia. SASE, a comprehensive framework that converges network security and wide area networking (WAN) capabilities into a cloud-based service, offers numerous benefits. However, determining an organisation’s readiness for such a transition and effectively planning its implementation are critical steps. This blog delves into the key factors that should be considered and outlines an approach for planning and implementing a SASE architecture.

Understanding SASE Readiness

Transitioning to a SASE architecture requires careful consideration of several factors. These include the current IT infrastructure, security needs, network demands, and the organisation's overall digital transformation strategy.

1. Assessing Current Network and Security Infrastructure

The first step is to assess the existing network and security infrastructure. Understanding the current setup helps in identifying what can be integrated into the SASE framework and what needs upgrading. This assessment should include an evaluation of existing WAN, cloud services usage, security tools, and policies.

2. Identifying Organisational Needs and Goals

Every organisation has unique needs and goals. Identifying these is crucial in tailoring the SASE implementation to align with business objectives. Consider factors like the scale of remote work, reliance on cloud applications, and specific compliance requirements relevant to Australian regulations.

3. Evaluating Workforce Distribution and Mobility

The distribution and mobility of the workforce are key factors in SASE adoption. Organisations with a significant remote or mobile workforce will benefit greatly from SASE's ability to provide secure, consistent access regardless of location.

4. Considering Cloud Adoption and Integration

SASE is inherently cloud-centric. The level of an organisation’s cloud adoption and integration plays a pivotal role in determining SASE readiness. A higher reliance on cloud services typically indicates a smoother transition to SASE.

5. Understanding the Security Landscape

Assess the current security landscape, including threat vectors, security incidents history, and compliance with standards like the Australian Privacy Principles (APPs). This assessment helps in understanding the security enhancements that SASE can bring.

Planning and Implementing SASE Architecture

Once an organisation’s readiness is established, the next step is the strategic planning and implementation of SASE.

6. Developing a Strategic SASE Roadmap

Develop a comprehensive roadmap for SASE implementation. This should include timelines, milestones, resource allocation, and specific objectives. The roadmap must be aligned with the overall IT strategy of the organisation.

7. Choosing the Right SASE Solutions and Partners

Selecting the right SASE solutions and technology partners is critical. Look for solutions that offer the necessary integration capabilities and partners with experience in deploying SASE in similar organisational environments.

8. Pilot Testing and Phased Rollout

Before a full-scale rollout, conduct pilot testing with a small user group or department. This helps in identifying potential issues and making necessary adjustments. A phased rollout approach minimises disruption and allows for gradual adaptation.

9. Training and Change Management

Effective training and change management are essential for a smooth transition. This involves educating IT staff and end-users about the new system, its benefits, and best practices for using it.

10. Continuous Monitoring and Adaptation

Post-implementation, continuous monitoring is crucial to ensure the SASE architecture is performing as intended. Be prepared to make adjustments based on evolving needs and technological advancements.

11. Ensuring Compliance and Data Protection

In the Australian context, ensuring compliance with data protection laws and industry regulations is vital. Ensure that the SASE solution adheres to these requirements, providing adequate data protection and privacy controls.

12. Real-World Example: SASE Implementation in an Australian Company

In a recent project with an Australian financial services company, the transition to SASE involved a comprehensive evaluation of their existing WAN and security setup, followed by a strategic implementation plan. The result was an enhanced security posture, improved network performance, and streamlined management, aligning with their digital transformation goals.


Transitioning to a SASE architecture is a significant yet rewarding journey for organisations looking to enhance their network security and efficiency. By thoroughly assessing readiness, strategically planning the implementation, and continuously adapting to changing needs, businesses can successfully leverage SASE for a more secure, agile, and future-proof IT infrastructure.

In the evolving digital world, the ability to adapt and embrace innovative solutions like SASE is key to staying competitive and secure, particularly in the diverse and dynamic Australian market.
