Future Architecture of Secure Access Service Edge: SASE

In today's era where digital transformation is rapidly advancing, the security and network performance needs of companies are increasingly growing. Traditional network and security models face challenges in meeting the demands of flexibility, security, and performance. However, Secure Access Service Edge (SASE), introduced to us by Gartner in 2019 with the blog post titled 'Say Hello to SASE!', presents an innovative approach designed to address these issues.

What is SASE?

SASE can be defined as a framework that combines security and the network. This approach enables secure access from anywhere by providing a cloud-based service interface for both network and security. By converging traditional Wide Area Network (WAN) and security services, SASE offers organizations a more flexible, scalable, and cost-effective solution. Cloud computing, Wide Area Network (WAN), security services, Zero Trust architecture, Edge Computing, and user experience optimization are the foundational elements of SASE. These integrated technologies provide companies with an approach that integrates flexibility, security, cost-saving, and scalability.

Benefits of SASE

Flexibility and Mobility:

SASE enables secure access for employees from anywhere, a significant advantage for companies in today's increasing trend of mobile work. Employees can securely access company resources even when outside the office.

Cost Savings:

Traditional network and security infrastructures are often expensive and complex. SASE reduces these costs with a cloud-based service edge. Centralizing hardware and software infrastructure in a cloud service brings about cost savings.

Security and Adaptability:

SASE automatically adjusts security and network policies based on the user's and device's location. This allows companies to respond more quickly to evolving threats. Additionally, security measures like data encryption enhance information security.

Scalability:

With its cloud-based structure, SASE solutions are easily scalable. As companies grow, these solutions can support more users and devices.

The Future of SASE

Expected to reach a market value of $1.9 billion USD in 2023 and forecasted to grow to $5.9 billion USD by 2028, SASE is being increasingly adopted by more companies. Particularly with the continuous rise in remote work and mobile access needs, the importance of SASE will further escalate. Moreover, through integration with technologies like artificial intelligence and automation, SASE will evolve into a smarter and more responsive structure.

In conclusion, Secure Access Service Edge (SASE) offers a modern solution by combining secure access and network services, providing companies with a more secure, flexible, and scalable infrastructure. With the adoption of SASE in the future, companies are likely to become more effective in digital security and network management.
